We have organised the rating for each attribute bellow into a scale of 1 to 4 (1 being not so desirable to 4 which is most desirable). Our scoring system is based on data collected from all BTO launches and SERS program since year 2010 which consist of more than 250 developments with more than 200,000 units in total (on average, HDB launch 15,000 to 20,000 units per year).
The best way to reduce heat intake has always been avoiding it in the first place. The understanding of heat intake varies due to geographical location. In Singapore, we try to avoid heat intake from the west sun (afternoon sun) at all cost due to Singapore being located along the equator, which mean closer to the sun than other part of the Earth. Being a tropical climatic country also means that we don’t have 4 seasons and we don’t need the extra warmth from the sun. Sun radiation carries along UV (ultraviolet) and IR (Infrared) wave which is detrimental to the building enclosure as well as the interior spaces and heat up the building a lot faster than the air-con can cool it down.
The higher the unit, the hotter it will be as hot air rises. On top of that, increase usage of air-con which contribute to hot air being emitted from the condenser unit (a.k.a. outdoor unit) will also move upward. Thus, affecting the higher units as the building goes up higher with almost all units these days using air-con. So, the challenge is about finding a balance between having nice view with higher floor vs increase heat intake due to height increase. Architectural elements introduced on the building façade may or may not help in reducing the heat intake as the design are standardised throughout the whole development regardless of the effectiveness for it. Therefore, detailed analysis needs to be done to ascertain the effectiveness of these elements.
Punggol Point Crown is located within the North East Region under URA Planning area. This development continues the expansion of Punggol Township, which spread to the Northern tip. Based on Master plan 2019, site reserved for residential within this vicinity have been almost fully launched under BTO scheme. From our early assessment, if you are going to go for a 4-room, you will have a 69% chance of getting a hot unit. A 5-room will be worst off at 70% chance of getting a hot unit. A hot unit mean the main façade of the unit having at least 3pm west sun exposure (note that this assessment is based on units having a standard horizontal shading device of at least 300mm to 600mm). We rate the west sun exposure for this development at 1 out of 4 for both 4-room and 5-room.
At hausanalyst, we have been collecting wind data released by Singapore Meteorological Service since 2014 which was recorded at Changi Airport Station. Based on the data collected, we found a consistency in terms of the frequent direction of prevailing wind as well as the major wind direction which happen almost 1 in 5 during the prevailing season. 3 other prevailing wind directions only happen 1 in 10 during the prevailing season. Knowing which of these wind directions and when does it happen will greatly help when selecting a unit.
Based on recorded prevailing wind data from 2014-2017 which we have analysed, if you were to get a 4-room unit, your chance of getting a prevailing wind will be at 30% while getting a 5-room will put you at a higher range of 57% chance. We define the prevailing wind exposure as the wind hitting diagonally onto the surface of the external wall of the unit, usually the façade with the most numbers of windows. While we welcome wind exposure during a hot day, we may not like it during heavy rain as it will help to intensify the rain hitting directly at the windows and some instances cause seepage due to poor workmanship on window frame. Read more about prevailing wind exposure here (https://www.hausanalyst.com/bto-analysis/good-housing-prevailing-wind-exposure). We rate the wind exposure for this development at 2 out of 4 for 4-room and 3 out of 4 for 5-room.
Overall, we rate this development at 11 out of total 20 for 4-room and 12 out of total 20 for 5-room.
