![]() ![]() Portability of the diagnostic equipment is essential in these surveys which may include access into some tight spaces. Infrared inspection of the attic floor with air forced from the occupied space through ceiling by-passes, and inspecting the interior of the building when outside air is being sucked through the envelope reveals unexpected leakage sites. Although missing or poorly installed insulation may lead to a substantial energy penalty, it is the search for air leakage sites that often has the largest potential for energy savings. Combining the infrared scanning with positive or negative building pressures, induced by a "blower door" or the building ventilation system, considerably extends the periods during which meaningful diagnostics can be conducted. The evaluation of the thermal integrity of building envelopes by infrared scanning tech-niques is often hampered in mild weather because temperature differentials across the envelope are small. Simulation technology as feedback loop will lead to better performative building envelope. ![]() Optimizing the building envelope design is crucial strategy for reducing CO2 emissions and long-term energy reduction in building sector. Comparative analysis on the data will determine logical variation between opening and shading device composition and cooling energy consumption. This research applied simulation method using Autodesk Ecotect to investigate simultaneously between variations of wall and window ratio, shading device composition and the implication to the amount of solar radiation, cooling energy consumption. The design strategies are considering orientation, window to wall ratio, material properties, and external shading device. This paper examines performance of various design strategy on building envelope to limit solar radiation and reduce cooling loads in tropical climate. It appears as wall, window, roof and external shading device. Building envelope acts as interface layer of heat transfer between outdoor environment and the interior of a building. In fact, the amount of energy used for cooling or heating building is implication of building envelope design. Global CO2 emissions are emitted from HVAC (Heating, Ventilation, and Air Conditioning) occupation to provide thermal comfort in building. ![]() Performative building envelope design correlated to solar radiation and cooling energy consumptionĬlimate change as an ongoing anthropogenic environmental challenge is predominantly caused by an amplification in the amount of greenhouse gases (GHGs), notably carbon dioxide (CO2) in building sector. ![]()
