PROJECT 1: CASE STUDY - ANALYSING PASSIVE DESIGN STRATEGIES
This subject aims to create awareness and understanding of designing buildings that respond to local climatic conditions of Malaysia which is hot and humid that reduce the energy load of mechanical air-conditioning systems. The introduce thermal mechanisms such as solar radiation, heat conduction, heat resistance and heat convection that determine indoor temperatures, including how building elements respond to thermal mechanisms as well as various design strategies to reduce heat gain of interior spaces through control of variables.
For Building Science 1, we learnt passive design by taking advantage of natural climate to maintain thermal comfort without mechanical heating or cooling, incorporating the principles of passive design in building: • Significantly improves comfort • Reduces or eliminates heating and cooling bills • Reduces greenhouse gas emissions from heating, cooling, mechanical ventilation and lighting. Building envelope is a term used to describe the roof, walls, windows, floors and internal walls of a building. In a tropical climate, the envelope should controls heat gain and exclusion of rainwater. Well-designed envelopes maximize cooling through air movement and exclude the solar radiation. The fundamental principles of passive design are relatively simple and can be applied to various climate zones, house types and construction systems.

Learning Outcomes
Upon the successful of this module, I was able to identify environmental conditions related to site conditions, climate, etc according to Malaysia's climate.Besides, I can explain the effects of the sun on the thermal performance of buildings and the effect of insulation, thermal mass and air movement on thermal performance of buildings then applied the suitable devices by following the legalism instructions such as MS 1525, Green Building Index and etc. Futhermore, I was able to applied the skill of using computer sofeware like Revit and Ecotect in simulate the effectiveness of shading devices of the building and it is very useful for my future studies on effectiveness of design even in my studio project. This case study is very useful for my future design because of the real site experience allowed my to remembered the important of passive designs and making the building more functional and aesthetic. I am really enjoy this project and hope there is more real site experience expose for student to learn practically instead of theory.

GROUP
For this project, it required 5 to 6 person in a group to have a case study on Green Building Index (GBI) rated passive design building in Klang Valley and Singapore. For, my group which have 7 person, Chua Chang Yeong, Chia Wee Min, Hiew Eyang, Tan Zi Jian, Teoh Hui Yu, Jonathan Ong Yii Siang and me, decided to choose Klang Valley as our case study location as it just near by and easy for us to return there to gather more information. Our case study building is KLIA2 - Kuala Lumpur International Airport Terminal 2. This building is rated Gold in GBI rating and the main focus will be Terminal Complex- Gateway, as it a public space and required thermal comfort design.
The passive design we found in this building are U-shaped roof Overhang, Low E-glass, cross-ventilation, stack ventilation and Orientation of the building. The orientation of this building is in special case as it need to follow the wind direction for the airplane to take off and landing.
Following is our passive design analysis of KLIA 2 and our conclusion to the effectiveness of passive design of KLIA2 Gateway building.
