Project 1 – Case Study: Analyzing Passive building design strategies
In a group of 6, we were required to choose a space in Taylors' University Lakeside Campus and identify basic building design for thermal comfort for this space and also the external surfaces for this space.
We also had to record and analyze the existing condition in terms of thermal comfort of the interior directly affected by the environmental factors such as sun and wind.
Aside, we had to document all environmental factors (4) for a day and average for a yearOur group chose empty space located outside LT9/10, in consideration that the space is rather wasted and has the potential to function as a relaxation/ chilling spot.
We proposed a zero-electricity eco- cooler to help in the reduction of the heat levels and to improve wind circulation.We also proposed a louvered facade to facilitate heat reduction and promote proper ventilation.
Below are photos of our Research Boards, and analysis we recorded throughout the project.
REFLECTION
A.)Shading
Solar control and shading can be provided by a wide range of building components including:
• Landscape features such as mature trees or hedge rows;
• Exterior elements such as overhangs or vertical fins;
• Horizontal reflecting surfaces called light shelves;
• Low shading coefficient (SC) glass; and,
• Interior glare control devices such as Venetian blinds or adjustable louvers.
B.) Passive Design
Passive design results when a building that is designed simply works “on its own” to achieve sustainability to reduce energy consumption. The siting, layout, section, materials selections and features incorporated into the building design create a positive energy flow through the building and “save energy”.
The main principles of passive cooling for buildings in the tropics are:
• Avoid heat gain
• Encourage natural ventilation
• Create cool outdoor areas
• Make use of natural light
The variables to consider for implementing the passive design principles are orientation, shading, thermal mass, insulation, ventilation, windows, and lighting.
Design Integration
For our final studio, we had to do a Building Science integration for our chosen design. Below is my design integration work.

Design Integration
I applied a green roof as a passive cooling strategy in my design, and the use of solar panels to generate solar energy
C.) Ventilation
Ventilation is dilution of polluted air by bringing in / mixing with outside fresh and unpolluted air
Natural ventilation can be achieved through the use of windows.
In order to achieve maximum ventilation through windows, the following principles have to be followed:
1) Orient the building to the wind direction for maximum pressure and air velocity
2) Install operable windows of the correct type.
3) Use landscaping elements to channel breezes.
4) Properly locate and size windows for cross ventilation.
5) Reduce internal barriers to ventilation (i.e. walls).
6) Use wing walls if cross ventilation is not possible.
7) Use stack ventilation to create a chimney effect.
Natural ventilation is based on two different principles, which are cross and stack ventilation.
Cross ventilation is wind-driven, whereby stack ventilation relies on the difference of air pressure within a building.
Natural ventilation is often driven both by the wind and stack effect i.e. hybrid ventilation.
Design Integration
I used windows to achieve both cross- ventilation and single-sided ventilation in my studio design.
