| Abstract | ||||
| Nowadays Climate change is the main dilemma urging the world actions to mitigate it, mainly through fossil fuel independency and energy consumption management. Energy deficient performance of the building envelope in residential buildings is a major driver increasing energy consumption rates. Since the cooling loads and lighting are on top of the electric consumption rates in housing, then a key mitigator to improve the energy efficiency performance of a building envelope is the adequate management of energy flow through the household by the passive strategy (cooling and daylighting) techniques to acquire the best advantage of the local climate. Selecting the high standard housing segment represented in new Gated communities, spotting the gap between the formal and new market criteria and how it is widely spreading with no considerations to their building envelope energy deficiency performance and accumulation of energy consumption loads urges the need to take the High standard housing into an actual high standard not only per income level, but also in its energy high performance aligning with global aspect. Cases studied were analyzed to observe their passive cooling techniques implemented in the Building Envelope to improve the energy efficiency performance. Then one base case study (SODIC EAST-MVvilla) is selected and adapted with previously induced eight passive cooling techniques then simulated with DesignBuilder software to assess the energy consumption, thermal performance, and CO2 production of the building. The study resulted in significant electric consumption annual decrease by 41% thermal comfort annual improvement by 66% that lead to a decrease in CO2 production by 41% annually and that is when a building improves its energy efficiency utilizing the building envelope using passive cooling strategies. | ||||
