"Task methodology

• Choose a building that best features 2 passive design strategy for tropical climate. Group will select one building in Klang Valley.

• Selection will be based on the following,

- that buildings should be a certified and recognized as Green Building, refer to the building listed in the green building index (http://www.greenbuildingindex.org/organisation-certified-buildings-NRNC.html),
- certification may other be Platinum, Gold or Silver .
- please refer to tutors for other buildings.

• Have a thorough research on the passive design strategies, the principles and details needed for these passive design strategies to perform best in tropical climate and to achieve thermal comfort in this building/space.

• Identify two (2) passive design strategies used for a building.

• Identify an instrument /equipment or software/interview/survey to aid in proving that the passive design strategy is effective in this building.

- eg: shading devices – simulation in revit software - wall or roof component – calculation of u-value - wind chimney – simulation in vasari

• Analyze the monitored temperatures, looking at the effects of solar radiation, thermal mass, insulation,

and ventilation.

• Explain how the thermal environment of your case study is affected from natural and man-made factors.

• Research poster should contain the following:

a. Building Introduction (images, pictures, diagrams, drawings and description)
b. Analysis of site and micro-climate (wind, sun, topography, etc.)
c. 2 passive design strategies, the principles, analysis of any one or more of the following;
i. Thermal Analysis; basically means using a manual calculation or computer program to
mathematically model the interplay of thermal processes within a building
ii. Wind Analysis (Vasari software); Airflow and air quality is an important aspect of
human comfort. Moving air helps people feel cooler, and natural ventilation is a
key strategy for passive cooling.
iii. Sun Analysis; analyzing the impact of the sun on a site, as well as the building’s location,
the spatial arrangement, orientation, window placement, daylight access and other design
features, the designer can take full advantage of passive solar design features and
increase the energy efficiency and comfort of the building.
iv. Concept and analysis of building’s passive design strategies. Highlight the 2 passive
design features used in each building and elaborate the effect and importance of it.
v. Appropriate visuals and diagrams (tables, charts, etc.) with appropriate referencing and
citation where applicable. "

The building chosen for our group is Wisma REHDA with a Silver GBI rating. For this project, we studied one passive design strategy which is the ventilation blocks (West facade). Through intensive research and simulation, we presented our findings in the boards below.
