The engineering of building envelope aims is to achieve building energy efficiency which uses shading device to increase the shaded area. Also, to reduce heat gain by the building from solar radiation, this will reduce the energy load on the building. This paper aim to focuses on the deepening of technology of building envelope elements, and how the building envelope can control the thermal comfort as part of the indoor environment in a building that carries sustainability architecture. In conclusion, finally, reveal that the principles of passive design on building envelope have a great influence on the comfort level in the building. It is not possible to create a design that meets the thermal comfort requirements by emphasizing the design of building envelopes. The goal to be achieved in sustainable design is to minimize the use of the current design that takes much energy (almost14% world energy consumption) to address the issue of energy crisis lately.

“…In case of lack of a sufficient ensemble of reliable data on the thermal request, which may be due to the enlargement of the urban area connected to the district heating network, it is advisable to reconstruct the heat requirements during the heating season by using the following simple model. The heat demand is mainly dependent on the characteristics of the buildings (see for instance [26]) climate and human behavior [27]. Once the heat demand is known in some days, the demand in the entire year can be obtained as the function of the external temperature only.…”

“…The theory of the OTTV is based on the assumption that the envelope of a building is completely closed and consists of two values: (1) Envelope Thermal Transfer Value (ETTV) and Roof Thermal Transfer Value (RTTV) [17]. Whilst the ETTV is a measure of the heat transfer through the walls or envelope of a building, the RTTV is concerned with the heat transfer through the roof of the building.…”
