• This paper presents and optimizes the annual heating, cooling and lighting energy consumption associated with applying different types and properties of window systems in a building envelope. Through using building simulation modeling, various window properties such as U-value, solar heat gain coefficient (SHGC), and visible transmittance (Tvis) are evaluated with different window wall ratios (WWRs) and orientations in five typical Asian climates: Manila, Taipei, Shanghai, Seoul and Sapporo. By means of a regression analysis, simple charts for the relationship between window properties and building energy performance are presented as a function of U-value, SHGC, Tvis, WWR, solar aperture, effective aperture, and orientation. As a design guideline in selecting energy saving windows, an optimized window system for each climate is plotted in detailed charts and tables. ► We examine the effect of window systems on energy consumption of buildings in Asia. ► We propose the optimal window performance properties in Asian regions. ► We recommend a design guideline for optimal window selection with various climates. ► Charts of top 3 performing window systems with 5 typical Asian climates are plotted. ► Various window properties are evaluated by using a computer simulation tool.
