CASE STUDY TITLE A study of

Contextual Design Strategies

to achieve

Thermal Comfort in House 484, Damansara


INTRODUCTION -Gold award winning architecture design

-Contextual design features

-Home fitted very well on the site.

House 484 Country Heights Damansara


ISSUE Tropical- prime barrier to cross, unbearable heat

Role- contextual factors

architecturally maintain temperature within thermal comfort zone

Pay respect- produce positive thermal impact


OBJECTIVE the factor that affect human thermal comfort in House 484

STUDY-

the ability of the contextual factors to influence human thermal comfort in House 484

UNDERSTAND-

LEARN- the purpose of design

strategies used to encounter with the factors that affect thermal comfort

EAST SIDE SITE CONDITION SUN & WIND

Consider as most moderate zone, it receives morning sun exposure, yet benefit from afternoon shade. Therefore, it is a favourable location for outdoor morning and afternoon activities

WEST SIDE SITE CONDITION It receives afternoon sun exposure, yet benefit from morning shade. Not recommended for afternoon activities and shading must be provided if outdoor use is to be located here since it is the hottest and driest area of all zones.

DESIGN STRATEGIES

DESIGN STRATEGIES

Fully opened space to capture warming sun. Spaces with more activities carried like the living room, external terrace and swimming pool are designed facing to the east. Most of the house openings are designed at the east area to allow cross ventilation to occur. House 484 purposely designed to be extended out from the hills, which form a large overhangs to cater as much prevailing wind as possible.

Least fenestration. Most of the utilities room are designed to be place at the west side of the house.


DESIGN ACCORDING TO SUN & WIND

overhang To produce a vernacular design, the orientation of House 484 has been designed carefully together with the aid of the large extensive overhanging flat roof. Large overhangs and the low exposed areas (windows and walls) provide good shading and allow the openings to be left open most of the time for ventilation. Hence, overhang is an important supporting element to achieve thermal comfort.

opening The elongated structure with minimal partitions in the interior, allows easy passage of air and a cooler micro-climate. Openings are plentiful in House 484 since the body is the most vital area for ventilation in order to bring away heat gained and generate a cooling effect.

Typical architecture style to confront tropical weather

Openings are plentiful


Conclusion Contextual design strategies play a part in contributing to the thermal comfort in House 484 Contextual factors can produce a positive or negative impact which it depend on how is the utilization of it.
