Review on units taken (8 Aug 2015)

Before I proceed, I would like to share that I stumbled into certain renovation web page which also try to advice on wind and sun analysis. I’ll just make a record here.

1. The sun doesn't operate as what it’s shown because the sun operates in 3D and not 2D. Meaning if on 2D drawing like Site Plan shown by HDB, if there’s 2 block next to each other, it doesn’t mean 1 block will not received morning or afternoon sun because you thought that the other block is blocking the sun away.

2. When we say North-North East wind, it means the wind will blow from North or North East towards South or South West, NOT the other way round. This certain renovation website clearly don’t understand the wind direction as well as wind velocity in Singapore and yet trying to give advice which will definitely land you in the worst decision making process. Btw, average wind speed in Singapore is 2.5 m/s.

I hope if any buyers who signed up for renovation package will not be another group of disappointing customers later on.

This advice goes to buyers who may get ill advice from chat room and from ‘friend’ who are not from the architectural consultancy field majoring in residential. Just to share with you that NOT all architects design residential because there’s architect who just know how to design public facilities, prisons, hospitals, school etc. These are from my 1st hand experience working with my many ex colleagues who are doing different projects other than residential. I’ll share more on this when up and coming development launched later. 


Selection so far
#15-310; #15-320; #15-374; #15-380; #15-460; #15-462
Anyone ever wonder why the top 2 floors have the same price?  I would put it as discounted rate for getting the top most floor rather than mispricing. It has always been the case with BTO pricing that most of the top 2 floors will have the same price. Even with ferrocement secondary roof which supposedly to reduce the heat impact from sun directly above, the price should have reflect the effectiveness of this claim since it’s been used on all new BTO. Other than this, if the price is similar with other stack without water tank on top, I will choose the one without.

#02-350
Note that there’s a linkway connecting stack 312 to 350, this linkway should be about 2.4m high while top of the roof should be 2.8m at least. The linkway is connected to where the master bedroom is and the height different between top of roof to the bottom of master bedroom window should be at least 1.4m. Detailed height of the linkway may change along the process of construction. Best practice should be connecting these linkway to the gable end of the building where preferable no opening which may otherwise create security concern.


Stack 424
Note that North to North East wind happen from November to April every year and wind will bring smoke from the eating house to the back of the unit where the yard is located. Anything above 4th floor maybe affected depending if the exhaust shaft connected to the roof top of Block 610. In other words, if you are drying clothing, expect smoke from eating house.

#12-458; #11-440; #14-442; #14-430
Given an early queuing number, I would have gone for something more predictable than getting a unit which you will eventually be facing another block right in front of you due to the same plot ratio which means same height and same density.

Stack 432
Note that South to South East wind happen from Jun to September every year and wind will bring smoke from the eating house to the front of the unit where the Living Room is located. Anything above 4th floor maybe affected depending if the exhaust shaft connected to the roof top of Block 610. Best case scenario this will only happen in September when wind predominantly from South East.

Currently there’s no scientific ways of valuing or price a property. Conventionally properties are being priced based on floor height, potential view (which you won’t even know unless you subscribe to our analysis service), location and current surrounding resale price as guideline.


With due respect to all buyers who have chosen their units, these analysis are purely based on my technical view with the backing of my years of experience of doing residential projects and by no mean to offend anyone. 
   

I have added this http://raremerchandise.blogspot.sg/2015/07/how-accurate-is-this-sun-analysis.html in case you are curious! 

Sun
1. Sun angle do change the whole year round. Our analysis have been broken down to Mac 21, June 21, Sept 21 and Dec 21 to represent 4 quarters or sun movement which will affect the shadow casting and intensity of sunlight.
2. Based on NEA typical daily variation of UV index, it was noted that UV Index level in Singapore generally reaching high level from 11am to 3pm. Thus, most of the analysis here will be based on 3pm for easy reference.  Detail analysis for each unit and stack from 11am to 3 pm can be purchased via personalized report at an affordable amount which normally cost less than 0.05% of your property price (please email me at chua.soon.ching@gmail.com for details).
3. Based on full year analysis done, a true north south orientation of blocks doesn’t mean that you will only receive the ‘west sun’ on the west side of the building. My earlier assessment years ago were based on general acceptable norms and easy understanding for new buyers.
4. Based on completed BTO in the market, certain block/stack will have shadow cast over at certain time and days which can be anticipated years before it was built. Why it is important? I used to candidly tell my friends they can save on installing the day curtain which cost few hundred dollars if they know in advance they won’t even need it. Apart from that, seems like latest research have shown that technically UVB is good for health as opposed to what dermatologist previously claimed (https://www.youtube.com/watch?v=oAAlMYWtF_s).    

Wind
1. In Singapore, generally we received seasonal wind from North to North-East and South. This is based on mean wind movement of year 2014 collected by NEA and available for purchase via NEA website.
2. Any new developments in the future surrounding the analyzed BTO will affect the wind movement, thus I don’t recommend readers to take wind too much into consideration. Ventilation or air movement within a unit can be simulated as this is fixed and performance of the unit can be determine if the unit plan will cause stagnant air flow which may impact your health.
3. For generally understanding, mean wind movement in Singapore for year 2014 is as followed:
