Abstract:

Climate change and the environmental pollution during the building operation in the last years cause of the reconsideration of exits standards/guidelines in buildings. Recent studies show the nonconformity of these guiding documents, which do not fully consider the climate of the regions when building the recommendations. As a result of this lack, the building operation does not reach the energy efficiency together with the thermal and visual comfort.

This paper proposes a simple method to recalibrate the daylight standard with the Daylight Factor criteria for Vietnam based on analysis of the daylight climate potential of the location and the requirement of daylight usage on the relative time and space. This bio-climatic approach refers to the design of buildings in the consideration of local climate aimed at providing thermal and visual comfort with the rational use of solar energy and other environmental sources. The result of this study helps to improve the current standardized methods of day lighting evaluation in Vietnam with a modern approach. In order to conduct a meaningful comparison between different climate regions, an analysis of two input climate data for tropical Hanoi (Vietnam) and temperate Moscow (Russia) was considered.
