Color of North/South/East/West wall is assumed as cream.

Cross section of the precast concrete wall for the calculation of U-Value

The OTTV value acquired is 48.3W/m2 which com-plies with the MS1525: 2007 Code of Practice which states that the over-all building OTTV should be lesser than 50W/m2. However, the overall heat gain is still rather high.

Contributing Factor: Extensive use of glass walls in the façades of the building, particularly on the com-

mercial block of the West elevation (eg Ambank, Breadstory, Starbucks).

Effect: The large amount of glass used increases the Window-to-Wall ratio, which in turn

increases the heat conductance through walls (accounts for 19% of OTTV).

Solution:Reduce the amount of glass used on the facade and considering alternatives materi-

als to glass walls in the commercial area to yield a lower Wall-to-Window ratio.

Contributing Factor: Use of single glazing ordinary float glass on most openings.

Effect: The high U-Value of this type of glass increases the Heat Conductance through

Window value (accounts for 18% of OTTV).

Solution:Use of a double glazing glass (U-Value:2.32-3.18W/m2oC) which reduces the amount

of heat gain in the building that also results in a lower OTTV value.

Contributing Factor: Low value of horizontal projections to wall-window height ration.

Effect: The lower the [horizontal projections to wall-window height ratio] the higher the shading coefficient

value, thus the higher Solar Heat gain through window value (accounts for 63% of OTTV).

Solution:-Increase the depth of the horizontal projection to increase the [horizontal projection to wall-

window ratio].

-Use of a variety of shading tools such as the polycarbonate overhang on the commercial lot in the west façade and horizontal concrete projections in the commercial lot.
