Critical Reflection

After attending the effective communication module (SIE2016), I find myself more cautious about the usage of tenses, grammar and sentence structure in my English writing. This is because I recognize the importance of how our writing affects the reader’s understanding and reaction to the points made. In addition, I also pay more attention to ensuring that the cited sources as well as in-text citations are in the right format of APA style which are crucial in giving the necessary credit to the authors.

In the completion of assignments, we practised how to summarize professionally and perform tasks like introduction letters, reader responses, etc. which gradually allowed us to be more familiar with English through actual applications.

We were also taught how to present with the aid of slides and how to use videos and pictures to reduce the number of words, thus improving clarity in our presentation. Techniques such as good eye contact, posture, voice and pace were also covered. Professor Blackstone delivered the syllabus content clearly and provided us with useful online links for additional reference.

During the class, he put in a lot of effort and took the time to go through with everyone individually on certain assignments, allowing us to identify our mistakes and clarify any doubts on the spot. He also went the extra mile to highlight common errors made by the class or students in general to prevent us from repeating the same errors.

One key highlight of the module was the opportunity to do a team-based research project on developing engineering solutions to an identified technical problem. Through this project, I grasped the importance of teamwork and the need to communicate effectively within a group. Although there were occasional disagreements between groupmates during team discussions, I have learnt how to be considerate and tactful when liaising with one another. In addition, I also learnt to consider the opinions of others and how to write minutes for our team meetings in the correct format, which I believe will be important in the workplace in the future.

We also had the opportunity to gain the necessary skills in order to write a professional proposal report and letter of transmittal as part of the output of the project. While rewording from relevant sources for our proposed solutions in the report, this allowed us to appreciate the value of progressing as a team when teammates who were stronger in English supported those that were less confident in their English.

At the end of the module, I also attended the presentation showcase which allowed me to see groups from different classes presenting their ideas in a unique manner. The presentation showcase had a professional setting to it with 2 emcees, 3 judges, and a large audience. Every team that presented that day was well-prepared with attractive slides. Despite having a few of the members feeling nervous, each individual managed to come out of their comfort zone. A team that stood out for me is Bricknology, the team that had an interesting idea of using mycelium bricks that are formed from organic waste and the mycelium of fungus to construct a building. They were also awarded the best team in the showcase. As they happened to be in the same class as me, I was able to witness huge improvements in every single member of the team from the last round they presented in class. They seemed to be more confident when presenting and had good eye contact, voice projection, body posture and clear slides with little words. Their pace was also good, making the presentation easy to understand and engaging. I could see that they had put in a lot of effort into this showcase and the assignment. I see this as an inspiration and would like to learn from their strengths - not only from the Bricknology team but also from all the other teams who presented at the showcase.

Overall, this module has allowed me to build up my confidence in written and spoken English. I was also able to make many good friends in this class because of the number of interactions we had from the class activities. I would also like to take this opportunity to thank Professor Blackstone for all his effort in teaching this module to the class.

Annotated Summary

Wong, N.H., & Chong, A. (2010). Performance evaluation of misting fans in hot and humid climate. Elsevier Ltd – Building and Environment, 45(12), 2666-2678. Retrieved from https://www.researchgate.net/publication/222826861_Performance_evaluation_of_misting_fans_in_hot_and_humid_climate


This article is a study conducted by Wong & Chong (2010) to examine the effectiveness of misting fans in a hot and humid climate. The authors sought to evaluate the change in thermal comfort level with the use of misting fans as well as estimate the potential rise in biological pollutants brought about by the higher humidity due to the mists generated. To do so, field measurements at two similarly orientated food centres as well as an experiment within National University of Singapore (NUS) were conducted to determine the thermal conditions and thermal sensations created by the misting fans. Results showed that misting fans were largely more successful in lowering ambient temperature as compared to the non-misting fans, but the relative humidity recorded under the misting fans were consistently higher. Based on thermal comfort and thermal sensation voting outcomes, the lower ambient temperature seemed to have a greater effect on thermal comfort levels compared to the higher relative humidity. The effect of evaporative cooling from the mist generating system was also found to be enhanced at higher air velocity. From the use of collection of biological samples from the 2 food centres, it was found that the higher relative humidity provided a more conducive environment for bacterial and fungal growth. To tackle the increased growth of biological pollutants, the authors thus suggested a possible alternative called the two-stage indirect/direct evaporative cooling system. However, they also stated that there is a need for further studies conducted on the feasibility of such a system in a semi-outdoor area. Moreover, to enhance comfort levels as well as to address the problem of biological pollutants, there is also a need for studies to be conducted on the incorporation of a dehumidifier unit to further reduce air humidity levels.

Draft #3 Technical Report



1. Background Introduction

This report is developed in response to a call for proposals to recommend engineering solutions in a particular area of focus. The team decided to work on mitigating the effects of a warm and humid climate, that members of the university committee are currently experiencing in the Singapore Institute of Technology (SIT) Dover campus, for the up and coming Punggol campus.

In recent studies, the rate in which Singapore has been heating up is double that of the world at about 0.25°C per decade (Ng & Tang, 2019). The temperature in Singapore is expected to increase gradually to 40°C between the years 2045 and 2065 due to the amount of greenhouse gases the world continues to emit (Low, 2019). In addition to the rising temperatures from climate change, Singapore is forced to contend with high humidity levels throughout the year (Ng & Tang, 2019).

Being geographically located near the equator, the island experiences a tropical climate. Furthermore, Singapore is surrounded by ocean where the heat and wind will transport water into the country through the breeze and rainfall (Billy Aircon, n.d.). The high humidity and increasing temperature in Singapore may cause people to be more susceptible to heat-related health dangers (Ng & Tang, 2019).

In a case study based in Florida, Saint Johns County Public District were sourcing for ways to regulate the high humidity and temperature levels for washrooms in an elementary school. Situated in an already moist environment, the existing heating, ventilation and air conditioning systems that were controlled by thermostats failed to target the high humidity. This resulted in vast temperature swings which in turn made the washrooms too cold or warm. The implementation of dehumidifiers helped to remove moisture and return drier room temperature air into the washrooms and by integrating them with the air conditioning system, the high temperature and humidity levels were mitigated (Dehumidifier Corporation of America, n.d.).

Team WATERHACK recently conducted a survey on students on the climate in a school environment. According to the survey, nearly two-thirds of the twenty-five respondents feel humid in school, and more than half are facing high humidity related issues such as sweating while queueing for food. (See Appendix)

The team notes that the overall demand of water resources in Singapore will be twice as much by 2060 due to the country’s uprising economy and population growth (Public Utilities Board, n.d.). According to the Public Utilities Board (PUB), managing the water supplies to meet the growing demands of the country require the involvement and contribution of the community due to climate change. This explains how each individual plays an essential role in managing the water demands and ensuring sufficient water supply in the future.

Therefore, team WATERHACK feels that there is a need to address the warm and humid climate in Singapore by implementing measures to help reduce the effects of such climate on people. Simultaneously, the team aims to integrate water recycling solutions in hopes of reducing water wastage and contribute in conserving Singapore’s valuable water by recycling natural resources. All these can be accomplished by installing dehumidifiers in SIT campus at Punggol. Not only would dehumidifiers address the uncomfort and health issues faced by the university body, water conservation techniques will be put in place.

In this report, team WATERHACK will discuss about the ideal school environment for members of the university body in terms of climate, the problems that could arise due to higher relative humidity levels in SIT campus, the proposed engineering solutions developed to mitigate these problems along with a thorough evaluation of each solution and the water recycling benefits of implementing the chosen solution.



1.1 Current Observations in SIT Dover


In SIT@Dover, there are no current measures taken into place to regulate the humidity level in the school, especially in classrooms, where the majority of students spend most of their time. Although air conditioners are used to cool room temperature into a more conducive environment for effective studying, the humidity levels are still high.



1.2 Problem Statement
An ideal forward-looking university should be a conducive and comfortable place for students to be in. In the current SIT@Dover campus, the cold air released by the air conditioning in classrooms can be cooling but it might be unhealthy with the humid air surrounding us. Therefore, the team believes that SIT@Punggol campus should incorporate outdoor dehumidifiers in the campus so as to maximise student’s productivity in their learning process and at the same time, reduce the risk of any heat-related health dangers.



1.3 Purpose Statement

This report aims to propose the implementation of outdoor dehumidifiers in SIT@Punggol campus to the estate planning committee in hopes of mitigating the effects of high humidity on students.

2. Proposed Solutions

The team came out with two solutions in hope of providing a better learning environment for the future SIT@Punggol campus.



2.1 Implementation of outdoor dehumidifiers

In SIT@Dover, the team made an observation that outdoor dehumidifiers are not being used in the campus. In this case, outdoor dehumidifiers will be used to regulate the humidity inside the school campus specifically the classrooms.



2.1.1 Outdoor dehumidifiers


Outdoor dehumidifiers serves the same purpose as an average dehumidifier. An outdoor dehumidifier is to be placed outdoors compared to a dehumidifier which is placed indoors.

Dehumidifiers primary function is to remove excessive moisture from the air by drawing surrounding air into the device. The device will then remove moisture from the collected air through condensation, by converting the moisture in the air into water droplets before releasing the air back to the surroundings. These water droplets will be collected in a tank inside the dehumidifer and can be recycled for multiple purposes (Holmberg, n.d.).



2.1.2 Outdoor Dehumidifiers with air-conditioning system

The team proposes that SIT should consider on investing outdoor dehumidifier for the upcoming campus in Punggol as one of the solutions to combat the humidity level.

The outdoor dehumidifiers is to be used together with the air-conditioning system so as to provide students a better learning environment to study in the future campus. The team notes that the current air-conditioning system in SIT@Dover does remove some moisture from the air while at the same time lowers the room temperature, which as a result can worsen the room humidity level which further complicating the problem.

By incorporating outdoor dehumidifiers into the existing HVAC system in SIT@Punggol, the equipment can contribute to better air quality in the classrooms. The outdoor dehumidifiers contributes to the HVAC system by removing excess moisture, and treated cooled air to flow into the school’s main Air Handling Unit before being supplied to respective classrooms. This will result in cleaner air compared to just using air-conditioners itself in the classroom for the students.




2.1.3 Stakeholders Involvement

A dedicated outdoor dehumidifier in SIT@Punggol can overcome the issue of humidity level in the future, by directly delivering better air quality in conjunction with the air-conditioning system.

With this, the team is targeting the financial head of SIT@Dover to invest in an outdoor dehumidifier for well-being of the students. This is to help the student have a better study environment and prevent any health-related issues such as headaches. The team hopes to make a change in that for the future campus.



2.2 Implementation of outdoor misting system

The team also made an observation that no outdoor misting systems are used in SIT@Dover campus. As a result, outdoor misting system can be used in the future SIT@Punggol campus to reduce the surrounding temperature.

2.2.1 Outdoor misting system information

Outdoor misting system is an evaporative cooling method that lowers outdoor temperature on hot and sunny days. This system forces water out of the nozzles which will encourage the formation of fine mist. The evaporation of these fine mist will absorb heat energy from the surrounding and thus, lowering the temperature around the misted area (Wintering, 2017).
2.2.2 Location of outdoor misting system

2.2.2 Location of outdoor misting system
An ideal place for the outdoor misting system would be the sheltered walkways around the future SIT@Punggol campus.

3. Benefits of Proposed Solutions
3.1 Benefits of Outdoor dehumidifiers

Outdoor dehumidifiers being implemented can bring many benefits to the school.

In general, an ideal room or space should maintain a humidity level of 40 to 50% (Sylvane, n.d.).



3.1.1 Proper use of recycled water
As the team aims to maximise water resources, the 3R’s implemented by National Environment Agency is a major element that he team referenced to.

“Gray water”, which is collected by a dehumidifier from the moisture of the outdoor air, is not drinkable but can be recycled for multiple purposes. This includes watering of plants in the school garden or even flushing of toilets. SIT@Punggol does not need to worry about wasting the unused water.



3.1.2 Saving costs from bills

SIT@Punggol can also benefit from saving costs from the electrical bills. Combining of outdoor dehumidifiers with air conditioning system allows the school to save money.

As humid air takes more energy for the air conditioning to cool down the room temperature, the use of outdoor dehumidifier will precool the air. Thus air conditioning system will use less energy on its cooling capacity to remove sensible heat and more on removing latent heat. Therefore, SIT could consider this as one of the benefits in the long run to maintain the school’s financial.



3.2 Benefits of outdoor misting system

Outdoor misting system is more environmentally friendly than conventional air conditioner because its system only uses water to reduce the surrounding temperature and because of that, it will not produce any harmful greenhouse gases.


4. Limitations of Proposed Solutions
4.1 Limitations of Outdoor Dehumidifiers


The drawbacks of an outdoor dehumidifier includes the maintenance and cost.

A good outdoor dehumidifier is essential to maintain the indoor air quality for an optimal comfort of the students in the campus. SIT@Punggol have to regularly clean the filters of the dehumidifier to ensure healthier dehumidified air is being released back into the classrooms. Adding on, water collected have to be emptied to prevent mosquitoes from breeding. Research has shown that a school physical environment can make an impact on the students’ productivity in the campus.

Choosing the accurate size and specification for SIT@Punggol can be one of the challenges the management could face when implementing and outdoor dehumidifier in the school campus. As the team is unaware of the new layout for SIT@Punggol, coming up with a suitable size for outdoor dehumidifiers would be a challenge. The different sizes of outdoor dehumidifiers have different prices attached to it. The larger an outdoor dehumidifier is, the equipment gets more expensive.

To mitigate these issues, the team suggested that dehumidifier will only operate when it reaches a certain percentage of relative humidity level. Otherwise, the dehumidifiers will not operate to save energy costs from the bills. This could also regulate the humidity level when it is necessary.




4.2 Limitations of Outdoor misting system

The system has to be maintained constantly. The contaminated water from the collected water will pose a serious hazard to the users. Mist being produced by contaminated water can illnesses such as Legionnaire’s disease and Pontiac fever. Furthermore, it could be a breeding spot for mosquitoes.


4.3 Evaluation of chosen solution

By comparing the two solutions stated above, the team decided to go with the outdoor dehumidifiers. Despite being very costly in implementing the outdoor dehumidifiers, the benefits can be considered in the long run for the campus in Punggol. SIT@Dover could be an ideal place to testbed the outdoor dehumidifiers. Outdoor dehumidifiers have the potential of mitigating the humidity level at the same time provide good air quality to the students.




5. Methods and Procedure
In this section, the team will highlight the techniques used to gather all the relevant information.

5.1 Primary research

The team decided to use survey and personal observation for the report.

A survey was conducted to find out how the students feel about the humidity level in SIT@Dover. A total of 25 students responded to the survey. (see Appendix)

Through this survey, the team observed that the humidity level has to be mitigated for the comfort of the students in the upcoming campus in Punggol.

1.1 Problem Statement

An ideal forward-looking university should be a conducive and comfortable place for students to be in. In the current SIT@Dover campus, outdoor study areas can be very warm during hot days which will cause students to feel muggy even with the presence of fans. Therefore, the team believes that SIT@Punggol campus should incorporate dehumidifiers around outdoor study areas so as to maximise student’s productivity in their learning process and at the same time, reduce the risk of any heat-related health dangers. These portable dehumidifiers can play a part in lowering the humidity level around the vicinity which will enhance students’ well-being when studying outdoors around the new campus.

1.2 Purpose Statement


This report aims to propose the implementation of portable dehumidifiers in outdoor study areas around SIT@Punggol campus to the estate planning committee in hopes of mitigating the effects of high temperature and humidity on students.

2. Proposed Solution


The team came out with two solutions in hope of providing a better learning environment for the future SIT@Punggol campus.


2.1 Implementation of dehumidifiers


In SIT@Dover, the team made an observation that dehumidifiers are not being used in the campus. In this case, outdoor dehumidifiers will be used to regulate the humidity inside the school campus.


2.1.1 Outdoor dehumidifiers


Outdoor dehumidifiers acts the same as an average dehumidifier. Dehumidifiers primary function is to remove excessive moisture from the air by drawing surrounding air into the device.

These water droplets will be collected in a tank inside the dehumidifer and can be recycled for multiple purposes (Holmberg, n.d.).


2.1.2 Adjusting the setting of dehumidifiers


As dehumidifiers generally operate via electrical power, excessive usage could increase the bills. In order to reduce the electrical power consumption, the team suggest that dehumidifier will only operate when it reaches a certain percentage of relative humidity level. Otherwise, the dehumidifiers will not operate to save on energy costs.


2.1.3 Location of dehumidifiers


The team proposed to implement the outdoor dehumidifiers near outdoor study areas where these areas tend to be torrid during warm weather, decreasing the likelihood of health-related effects posed unto students.


2.2 Implementation of outdoor misting system


2.2.1 Outdoor misting system information


Outdoor misting system is an evaporative cooling method that lowers outdoor temperature on hot and sunny days. High-pressure pump is usually connected to a water source where water will then evaporate in warm air. The small nozzles enable the formation of mist which hence cool the area from being too hot.


2.2.2 Location of outdoor misting system


An ideal place for the outdoor cooling system would be the sheltered walkways if it is available in the new SIT campus in Punggol.



3. Benefits and Drawbacks


3.1 Benefits of Dehumidifiers



According to an article, a portable dehumidifier is likely to consume 160 kilowatt hours per month (kWh) and burns less energy compared to a typical air conditioner (Holmberg, n.d.). This shows that dehumidifier does not utilise much power and this can save cost for the electricity bills in the future SIT@Punggol campus.


In addition to saving energy, dehumidifier able to collect water through the compression warm air water collected also known as ‘grey water’ can be recycled to water the plants or even flushing of toilets.


3.2 Limitations of dehumidifiers


Choosing the accurate size and specification for the outdoor dehumidifiers is one of the main challenges. As the team is unaware of the new layout for SIT@Punggol, coming up with a suitable size for outdoor dehumidifiers would be a challenge.


3.3 Limitations of outdoor cooling mist system


The system has to be maintained constantly. The contaminated water from the collected water will pose a serious hazard to the users. Mist being produced by contaminated water can illnesses such as Legionnaire’s disease and Pontiac fever. Furthermore, it could be a breeding spot for mosquitoes.

Draft #1 Technical Report (Introduction)


Background Information
In recent studies, the rate of Singapore heating up is double than that of the world at about 0.25°C per decade (Ng & Tang, 2019). The temperature in Singapore could increase gradually to 40°C between the years 2045 and 2065 due to the astronomical amount of greenhouse gases the world continues to emit. In addition to the rising temperatures from climate change, Singapore is forced to contend with high humidity levels throughout the year (Low, 2019).

Being geographically located near the equator, the island undergoes a tropical climate. Furthermore, Singapore is surrounded by ocean where the heat and wind will convect water into the country through the breeze and rainfall (Billy Aircon, n.d.). Hence, the high humidity levels as a result of rainfall and temperature from climate change may cause people to be more susceptible to heat-related health dangers (Ng & Tang, 2019).

According to National Climate Change Secretary (NCCS, 2018), water resources is one of the elements that would be affected by climate change. Upturn in the unpredictability of weather patterns could pose a plethora of obstacles to the management of water resources. In Singapore, spells of drought can affect the dependability of its water supply, whereas unforeseen events of intense rainfall could swamp the drainage system, causing flash floods. With reference to the Public Utilities Board (PUB), managing the water supplies to meet the growing demands of the country require the involvement and contribution of the community (PUB, 2019). This explains how each individual plays an essential role in managing the water demands and ensuring sufficient water supply in the future.

In this report, team WATERHACK will discuss about the ideal school environment in terms of climate, the problems that arise due to higher relative humidity levels in Singapore, the proposed engineering solution developed to mitigate these problems and the water recycling benefits of implementing this solution.

Draft #3 Summary_ReaderResponse: Smart buildings: What 'smart' really means

In the article “Smart buildings: What 'smart' really means”, Lecomte (2019) states that having certification with standardized rubrics is fundamental for smart buildings to wholly emerge in the “built environment”. Lecomte mentions that the lack of unanimity from various stakeholders has delayed the drafting of standardized rubrics. Hence, private and public sectors design their own rubrics to assess smart buildings but their rubrics vary from one another. However, current private and public rubrics have been unsuccessful in tackling the complicated and expanding aspect that buildings will perform in “smart cities”. Lecomte emphasizes that one crucial component to be included in the standardized rubrics would be cyber risk management as cyber threats “increase exponentially” along with more advanced and integrated technology in smart buildings. Lecomte concludes that holistic and reliable “smart building certifications and rubrics” will be the foundation of a “functioning market for smart real estate”.


While Lecomte stated his case for establishing smart building certification under standardized rubrics and discussed inconsistencies in current indicators, he did not suggest concrete proposals to fully address the challenges.


First of all, Lecomte mentioned the need for “common standards and metrics” in smart building certifications, given their importance in smart cities. He also cited the success of globally recognised green building certification, LEED (Leadership in Energy and Environmental Design) certification. Such standardized certification system will offer a clear method for smart buildings to be benchmarked against consistent rubrics, and allow for the identification of improvement opportunities. This view is shared by Smeenk (2018) who stated in an article that recognized “industry-wide smart building certification levels” will “become the basis” for leaders to understand and develop smart cities. In addition, LEED has been thought to be critical in “transforming building practices” for the last 25 years by the U.S. Green Building Council (Long, 2018), and this emphasises the value for such a standardized certification system. Thus, like the use of LEED certification for green buildings, standardizing the metrics and rubrics for smart building certification has the potential to positively impact the built environment and accelerate the progress towards smart cities.


In addition to making the case for smart building certifications with standardized metrics and rubrics, Lecomte also highlighted the inconsistencies in smart building indicators used by different countries and corporations, which hampered the development of a standardized smart building certification. As different countries and corporations have unique priorities, it can be a huge challenge for them to negotiate the differences and come to an agreement on what a smart building really is. In a research paper published by the Czech Technical University (Lom & Pribyl, 2017), it was acknowledged that there are no straightforward and comprehensible framework which will allow cities to assess the benefits of their smart city solutions. Sullivan (2018) also suggested that varying definitions of smart buildings as well as the lack of wide-spread acceptance of existing indicators are key obstacles to the development of a standardized building certification programme. It appears to be a rather collective view that the road towards smart building certification with standardized metrics and rubrics will need considerable effort.


Lastly, although Lecomte listed the importance for consistent smart building rubrics and metrics, he did not make specific proposals on how to drive efforts to introduce a “universal framework”. For instance, a possible course of action is the recent push to develop and “launch the world’s first Intelligent Buildings Index” (Willow, 2019). This effort is being led by International Intelligent Buildings Organisation and will use “a state-of-the-art literature review, international stakeholder engagement and calibration against a global spectrum of smart buildings” (Willow, 2019). The index also promises to “ensure that the index stays abreast of latest industry and technological advances” (Willow, 2019). The process of developing this index can potentially deal with the inconsistencies that Lecomte mentioned in his article and help unify views of diverse stakeholders.


In conclusion, Lecomte’s article mentioned the importance of having a standardized smart building certification in the development of smart cities and listed key contributors hindering its development. However, he did not fully address how a “universal framework” can be developed. As the advancement of smart cities require significant time and effort for stakeholders to come together to standardize on a common metrics and rubrics for smart buildings, there is no better time than now to utilise a well-defined approach to progress towards the creation of a universal definition of smart cities.

Draft #2 Summary_ReaderResponse: Smart buildings: What 'smart' really means



In the article “Smart buildings: What 'smart' really means”, Lecomte (2019) states that having certification with standardized rubrics is fundamental for smart buildings to wholly emerge in the 'built environment'. Lecomte mentions that the lack of unanimity from various stakeholders has delayed the drafting of standardized rubrics. Hence, private and public sectors design their own rubrics to assess smart buildings but their rubrics vary from one another. However, current private and public rubrics have been unsuccessful in tackling the complicated and expanding aspect that buildings will perform in ‘smart cities’. Lecomte emphasizes that one crucial component to be included in the standardized rubrics would be cyber risk management as cyber threats ‘increase exponentially’ along with more advanced and integrated technology in smart buildings. Lecomte concludes that holistic and reliable 'smart building certifications and rubrics' will be the foundation of a 'functioning market for smart real estate'.


While Lecomte stated his case for establishing smart building certification under standardized rubrics, discussed inconsistencies in current indicators and the importance of cybersecurity, he did not propose concrete proposals to fully address the challenges.


First of all, Lecomte mentioned the need for “common standards and metrics” in smart building certifications, given their importance in smart cities. He also cited the success of globally recognised green building certification, LEED (Leadership in Energy and Environmental Design) certification. This view is shared by Smeenk (2018) who stated in an article that recognized “industry-wide smart building certification levels” will “become the basis” for leaders to understand and develop smart cities. In addition, LEED has been thought to be critical in “transforming building practices” for the last 25 years by the U.S. Green Building Council (Long, 2018), and this emphasises the value for such a standardized certification system. Thus, like the use of LEED certification for green buildings, standardizing the metrics and rubrics for smart building certification has the potential to positively impact the built environment and accelerate the progress towards smart cities.


Secondly, Lecomte highlighted the inconsistencies in smart building indicators used by different countries and corporations, which hampered the development of a standardized set of rubrics and metrics for smart building certification. In a research paper published by the Czech Technical University in Prague (Lom & Pribyl, 2017), it was acknowledged that there are no straightforward and comprehensible framework which will allow cities to assess the benefits of their smart city solutions. Sullivan (2018) also suggested that varying definitions of smart buildings as well as the lack of wide-spread acceptance of existing indicators are key obstacles to the development of a standardized building certification programme. It appears to be a rather collective view that the road towards smart building certification with standardized metrics and rubrics will need considerable effort.


Thirdly, although Lecomte listed the importance for consistent smart building rubrics and metrics, he did not suggest specific proposals on how to drive efforts to introduce a “universal framework”. For instance, a possible solution is the recent push to develop and “launch the world’s first Intelligent Buildings Index” (Willow, 2019). This effort is being led by International Intelligent Buildings Organisation and will use “a state-of-the-art literature review, international stakeholder engagement and calibration against a global spectrum of “smart” buildings” (Willow, 2019). The index also promises to “ensure that the index stays abreast of latest industry and technological advances” (Willow, 2019). The process of developing this index can potentially deal with the inconsistencies that Lecomte mentioned in his article and help unify views of diverse stakeholders.


Lastly, Lecomte underscored the importance of considering cybersecurity in the standardized rubric for smart buildings, but once again did not provide examples on how to do it. It is well known that cybersecurity will be a dominant topic for the smart building industry going forward and that technological leaps in recent years have brought about the advent of more frequent and highly sophisticated cyber-attacks (Blue Future Partners, 2018). In view of that, there are a few possible ways the smart building rubric can recognise and address these cyber threats. For instance, smart building vendors involved in cybersecurity need to be audited for their ability to stay ahead of potential cyber threats by consistently releasing timely new patches to upgrade their respective security management systems (Cyber Security Hub, 2018). Also, building operators need to be reminded through the rubrics to take the necessary precautions to boost their cybersecurity, such as "improving authorization controls and implementing stronger data encryption” (Blue Future Partners, 2018).


In conclusion, Lecomte’s article mentioned the importance of having smart building certification with standardized rubrics and metrics in the development of smart cities and listed key contributors hindering its development. However, he did not fully address how a “universal framework” can be developed. Furthermore, Lecomte also stated the need to consider cybersecurity in the smart building rubrics, but missed out suggestions on how to do so.

Draft #1 Summary_ReaderResponse: Smart buildings: What 'smart' really means

INCOMPLETE: 

In the article “Smart buildings: What 'smart' really means”, Lecomte (2019) states that having certification with standardized metrics is fundamental for smart buildings to wholly emerge in the 'built environment'. Lecomte mentions that the lack of unanimity from various stakeholders has delayed the drafting of standardized rubrics. Hence, private and public sectors design their own metrics to assess smart buildings but their rubrics vary from one another. However, current private and public metrics have been unsuccessful in tackling the complicated and expanding aspect that buildings will perform in ‘smart cities’. Lecomte emphasizes that one crucial component to be included in the standardized rubrics would be cyber risk management as cyber threats ‘increase exponentially’ along with more advanced and integrated technology in smart buildings. Lecomte concludes that holistic and reliable 'smart building certifications and rubrics' will be the foundation of a 'functioning market for smart real estate'. 

Lecomte has rightly stated that establishing smart building certification under a standardized rubric will be vital step towards advancing smart buildings (and smart cities), and also aptly brought forth suggestions on doing so. As smart buildings are the building blocks of successful smart city, having recognised “industry-wide smart building certification levels will “become a basis” for leaders to fully comprehend and execute their development of smart cities.  However, presently, there are no straightforward and comprehensible framework which will allow cities to assess their solutions on developing smart cities. (Lom & Pribyl, 2017) As reference solutionLecomte cited the system of “LEED (Leadership in Energy and Environmental Design) certification” in green buildings, well-known green building certification used globally. Developed in the early 2000s, LEED has been thought to be critical in transforming building practices, and this emphasises the value for such certification systems. (https://www.usgbc.org/articles/green-building-accelerates-around-world-poised-strong-growth-2021) Likewise, creating an inclusive smart building framework that guides stakeholders through the lifecycle of the smart building also has the potential to positively impact the built environment and allow the cohesive progress towards smart cities. 

Lecomte continues by addressing the limitations and inconsistencies in existing indicators in both private and public sectors. Different countries and corporations develop their own smart building indicators, and this is hindering the development of a standardized set of rubric for smart building certification. Indeed, such varying definitions of what smart building means and the lack of wide-spread market acceptance in existing indicators are obstacles to the development of a standardized rubric. (https://www.facilitiesnet.com/buildingautomation/article/Is-A-Smart-Building-Certification-On-The-Way---17485). With that in mind, efforts have been introduced in recent more recently to develop and “launch the world’s first Intelligent Buildings Index”. (https://www.willowinc.com/2019/06/11/introducing-the-worlds-first-intelligent-buildings-index/). The process of developing this index can potentially deal with the inconsistencies that Lecomte mentioned in his article and help reach a consensus among diverse stakeholders. The index also promises to “ensure that the index stays abreast of latest industry and technological advances.” (https://www.willowinc.com/2019/06/11/introducing-the-worlds-first-intelligent-buildings-index/). 

It is important to note, however, that buildings can serve different purposes, such as offices, residential properties, hospitals, just to name a few. . Although across these uses, basic building infrastructure needs (such as energy and water efficiency, trash, security, connectivity, parking management) are identical smart buildings must be designed according to the local climate in order to obtain the maximum of benefits”. (https://www.energyintime.eu/smart-buildings-beneficial/). In consideration of that, while a standardized rubric for smart building certification could be developed, in future it could be further expanded to a suite of certificates that may be tailored accordingly to local context or specific needs. This was also practised in the “LEED (Leadership in Energy and Environmental Design) certification, in which a suite of certifications were developed to address the uniqueness of different types of buildings (https://www.citylab.com/environment/2018/06/is-leed-tough-enough-for-the-climate-change-era/559478/). 


Furthermore, Lecomte underscores the importance of cybersecurity in the development of the standardized certifications under a standardized rubric for smart buildingsTechnological leap in recent years has brought together with it the advent of more frequent and highly sophisticated cyber-attacksand cybersecurity will be a dominant topic for the smart building industry going forward (https://medium.com/@BlueFuture/the-future-of-smart-buildings-top-industry-trends-7ae1afdcce78). Vendors involved in cyber security need to stay ahead of potential threats and take action to prevent cyber-attacks by consistently releasing timely new patches to upgrade their respective security management systems in order to allow their customers to be less susceptible to new methods of cyber-attacks. On the other hand, building operators also need to keep themselves up to date and take the necessary precautions to boost their cybersecurity, “such as improving authorization controls and implementing stronger data encryption, as well as working closely together with their IT department”. (https://medium.com/@BlueFuture/the-future-of-smart-buildings-top-industry-trends-7ae1afdcce78). This would require significant effort from the respective stakeholders. With that in mind, the standardised rubrics implemented and certifications released to respective stakeholders also need to be re-evaluated on a regular basis to ensure relevancy and competency to prevent vulnerabilities. 

Finally, to properly build up capabilities in the built industry, there should be an increased emphasis on education to building developers, building users, and the general public. Building developers should have platforms to share insights in conferences to use the standardized framework, be given opportunities to improve on the standardized rubrics from time to time. Building users and the general public should also be made aware of the potential benefits as well as risks involved in the use of smart buildings so that they do not inadvertently allow cyber-threats to take place within the smart buildings.
