​Why avoiding west sun is crucial?​

Heat (via direct sunlight) transfer via conduction, convection and radiation. Apart from windows, our parameter walls (mainly made of concrete and steel) are the largest external components which via conduction, convection and radiation will transfer heat into our home. While we can’t absolutely prevent all the above from happening, we can reduce the impact by choosing the unit with the least direct impact from any of the above.

Increased exposure to heat (via direct sunlight) will directly cause the following:
​
Material loss
1. higher electricity consumption
Units with higher internal temperature will need more active cooling (air-con), therefore, higher electricity consumption. If we take a HDB 5R as a sample and January 2020 usage as a baseline (351kWh), the total monthly differences (the rest of the year 2020) compared to January 2020 added up to 847kWh! Current SP Service going rate is at S$0.24/kWh and that’s S$203.28 in a year! A 4R extra usage added up to 670kWh, which is additional S$160.80.

2. materials wear and tear via direct and indirect heat transfer
Most will spend at least S$20,000 and above for interior renovation and fittings. Wear and tear will increase with heat, be it discoloration, material become fragile, etc. even before its warranty ended.   ​
Personal wellbeing
3. heat related illness-heat exhaustion
(https://www.mayoclinic.org/diseases-conditions/heat-exhaustion/symptoms-causes/syc-20373250)
(https://www.mayoclinic.org/diseases-conditions/common-cold/in-depth/humidifiers/art-20048021)
(https://data.gov.sg/dataset/relative-humidity-monthly-mean)
 
“Heat exhaustion is a condition whose symptoms may include heavy sweating and a rapid pulse, a result of your body overheating. It's one of three heat-related syndromes, with heat cramps being the mildest and heatstroke being the most severe.
 
Causes of heat exhaustion include exposure to high temperatures, particularly when combined with high humidity, and strenuous physical activity. Without prompt treatment, heat exhaustion can lead to heatstroke, a life-threatening condition. Fortunately, heat exhaustion is preventable.” - Mayo Clinic
 
(Notes: In Singapore, relative humidity is hovering above 72% since 1982, way above the comfort level of 30%-50%.) 

"High humidity can make your home feel stuffy and can cause condensation on walls, floors and other surfaces. Condensation can trigger the growth of harmful bacteria, dust mites and molds. These allergens can cause respiratory problems and trigger allergy and asthma flare-ups."- Mayo Clinic​

Climate change
4. high cooling activities (using air-con) lead to higher electricity consumption, which led to high carbon footprint and directly contribute to higher local temperature.
 
“The irony is the electricity for the air conditioning cooling me down as I recover is our second largest source of carbon emissions.
 
If the very act of powering our lives comes at the price of accelerating global warming, how are we going to get out of this carbon conundrum?”
​Dr. Janil Puthucheary, Senior Minister of State of the Ministry of Health of Singapore

5. Inherent issue of using concrete as building materials (nett CO2 emission) vs. timber (store and emit CO2). While most of the advance economy has started to move into timber construction, Singapore is still very much dependent on concrete as the main construction material due to limited know how and reluctant to innovate. As long as we are still using concrete, the urban heat island effect will keep on increasing.  

Parc Glen@Tengah is the 12/13th development within Tengah township. It’s also the 3/4th within the Park District after the Parc Woods@Tengah apart from being the 6/7th development with total units exceeding 1,000 unit in a single development. Across the common green, there is a site currently reserved for future high-rise development (based on HDB information) and classified as white site under URA 2019 master plan. Compare to earlier master plan for Tengah, this white site supposed to be a mixed development site. Since Parc Residences@Tengah have been developed under mixed development, the tagline as a white site will leave room for imagination.    
 
This development was designed by JGP Architecture (s) Pte Ltd. Tender for this development have been awarded back in January earlier this year to Chiu Teng Construction Co Pte Ltd.  

Why understanding the prevailing wind is important?

1. assist in cooling (heat mitigation)
A good prevailing wind exposure will help to mitigate heat impact, with condition, it faces the wider surface of the unit.
​
2. assist in ventilation (removing stagnant air, virus, bacteria)
(https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/Improving-Ventilation-Home.html)
No cross ventilation leads to stagnant air. Stagnant air leads to more viruses and bacteria trap in the same locality. When Covid19 hits, cross ventilation suddenly became all important to rid the interior spaces of the virus. ​

3. assisting in pollutants movement (dust from construction, place of worship)
Knowing your present and future surrounding may not be enough to prevent future discomfort if you don’t understand the direction of the prevailing wind and the season it happens.

4. high intensity wind load (high building)
Higher building within less denser surrounding will have to live with higher intensity of direct wind load. We welcome a good wind flow, but excessive wind flow will create havoc more than comfort.

5. splashing during rainy days
a. While everyone loves privacy by aiming for end lot/ units, the inherent issue is actually the exposure to water splashing (during rainy days with wind assistance) into the corridor which threaten to back flow into the immediate unit if the drainage system fails.

b. "The HDB said it received feedback about water seeping into flats from the owners of 24 units at Waterway Terraces I. Said a spokesman: "Most of these units face an open field, making them more prone to impact by heavy downpours." - The Straits Times July 15, 2015
(Notes: based on NEA recorded data for 14 July 2015, prevailing wind was coming from SSW, this is consistent with the reported case of units facing the open field which is facing SSW.) ​

Hello SC! 😊 Thank you so much for being a huge part of our BTO journey! As first time owners, at the start we depended on free online sources for tips on choosing a good unit. But all that turned out to be not backed up by data and evidences. Your sessions have been very informative and definitely more accurate than what is available for free online. We gained so much more insights and really learnt that choosing a good house is more than just choosing a corner unit or choosing an unit far away from the chute LOL. Your sessions helped us consider factors that we have not thought of before such as how much wind we will be getting, how much sun we will be getting and what view we will be getting. For the price we are paying you, what we get is really very worth it ah considering how much work you put in to get all these data. Thanks again for all your sharing! 🤗 we are really noobs at this but thanks to you we are no longer mindlessly choosing our unit 😆

Why viewing angle is important?

​1. actual view not being represented in scaled model
Gone were the days when homeowners get to choose from a completed housing development. With scaled models (usually 300 times smaller than the actual built product), homeowners can hardly visualise their immediate surroundings, let alone knowing their exact view from every window.  

2. visual coverage
The visual field of the human eye spans approximately 120 degrees of arc.  However, most of that arc is peripheral vision. (https://en.wikipedia.org/wiki/Vision_span) Knowing what you are capable of and allowing for a situation to maximize your capability is better than not having the option to do so. In short, if you can see wider view and further away, why should you settle for anything less?

3. architecture feature (window frame, fin, etc.)
External walls with shade and fins or windows with transom and mullion are architectural features which may serve as sun shading devices or just purely aesthetic features. The thickness, depth and location of these features will affect your viewing quality. 

4. visual privacy

5. awareness of surrounding ​

Why noise is emerging as an important good housing indicator?

1. personal wellbeing
(https://www.euro.who.int/en/health-topics/environment-and-health/noise/publications/2018/biological-mechanisms-related-to-cardiovascular-and-metabolic-effects-by-environmental-noise)
​
a. hearing loss
b. cardiovascular disease
c. stress and depression
d. insomnia
​ 
2. affecting daily routine (WFH)

Why building distance is critical in a selecting a good unit?

 1. claustrophobic (height vs distance)
 
2. provide shading from west sun

3. ventilation via prevailing wind movement
Better or wider building distance will allow for better prevailing wind movement.

4. privacy (in tandem to visual and noise)

5. living in 3D but planning in 2D
(https://www.ura.gov.sg/Corporate/Guidelines/Development-Control/Residential/Flats-Condominiums/Building-Length)
Current planning standards are more concern about the wall-like development (2D) rather than a more 3D approach of how to sparse the unit/ building away from e
