BUILDING SCIENCE : CASE STUDY - ANALYZING PASSIVE BUILDING DESIGN STRATEGIES
PROJECT
1
The objectives of this project are:
- To identify and define the principles of heat transfer in relation to building and people
- To understand what is thermal comfort and discuss factors relating to thermal comfort
- To analyze the effect of thermal comfort factors in a person and in a space
- To be able to criticize the design of the space in terms of thermal comfort by referring to MS1525, UBBL and GBI standards.
The tasks are:
- Choose a space in Taylor’s Uni Lakeside Campus, identify basic building design for thermal comfort for this space and also the external surfaces for this space. 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. Think in 3D and sections as the image in Pg 1.
- Have a thorough research on the basic design strategies and existing thermal comfort level and environmental factors affecting it. Document all environmental factors (4) for a day and average for a year.

REFLECTION
Throughout the course of this module, I have been enlightened on sustainable design and how to make my buildings more environmental friendly to save the earth for the better.
SHADING :
The sun path diagram in Revit that was created enabled me to visualize the sun expose area and sun shading area more clearly for my model in studio final project. I learnt that it is important to know the sun path of the site before proposing the building. It help me to identify the perfect views for my VIC and also allowed me to design the poetic spaces in my VIC. From knowing the sun path, it also allowed me to put shading devices into my final studio design.
PASSIVE DESIGN :
Passive design is a design that takes advantage of the climate to maintain a comfortable temperature range in the building or in a space. The passive design utilizes natural sources of heating and cooling, such as the sun and cooling breezes. It is achieved by appropriately orientating your building on its site and carefully designing the building envelope (roof, walls, windows ). Well-designed building envelopes minimize unwanted heat gain and loss. For my studio final project, I utilize the sea cooling breezes, I located the cafeteria and the decking near the sea to allow the visitors to cool their body from the sea breeze.
VENTILATION :
Natural ventilation uses natural outside air movement and pressure differences to both passively cool and ventilate a building. Most of the spaces in my building are open spaces. Natural ventilation is important because it can provide wind flow and move air without fans. For warm and hot climates, it can help meet a building's cooling loads without using mechanical air conditioning systems. I applied cross ventilation and stack ventilation to my final studio design.
