Purpose Electrochromic window (ECW) has been gradually applied to building engineering in recent years. However, empirical study of this technology used in green building design is still lacking. This study aims to verify the lighting and energy-saving performance of ECW under a specific geographical environment. Design/methodology/approach The meditation pavilion of Jinwan new materials research institute in Zhuhai is taken for research object. Three kinds of sun-shading techniques, namely, ECW, Low-E window and ordinary glass window, with same specifications are selected as the building facade structure for simulation. Day lighting analysis, sun-shading performance and annual energy consumption are separately simulated in the same environment by the Autodesk Ecotect Analysis software. The energy-saving performance of ECW is obtained by comparisons. Findings Result shows that the shading performance of ECW is much better than ordinary window and Low-E window. When ECW is used in the east, west or top lighting interfaces of a building, about 40% of the total solar radiation can be reduced during daytime in summer. Taking the ordinary glass window as a basic reference, ECW can save about 90% of the annual energy consumption of the glass house. ECW can effectively reduce the annual refrigeration energy consumption of buildings in the subtropical region. Practical implications Reasonable use of ECW in the subtropical region can effectively reduce the annual energy consumption of buildings. Originality/value It is a precedent study to analyze the lighting performance and energy consumption of a glass house with ECW. The energy-saving characteristics and beautiful appearance of ECW shall make it a future green building technology.

Around 40% of the electrical energy produced worldwide is consumed by the Buildings of Residential as well as Commercial types. Efficient usage and optimization of electrical energy leads to Nearly Zero Energy (NZE) Green Buildings and it helps in Economic growth and Social development in all countries. Apart from providing reduced energy consumption, Building energy optimization also minimizes the total energy costs, maximizes energy savings and consequently contribute less greenhouse gases to the environment. Though the installation cost of NZE Green building is quite high, the investment can be regained within the payback period with savings in the energy consumption. In this paper an Eco-friendly, Energy optimized, NZE Green building is designed by using efficient building simulation program known as BEOpt through HVAC technologies by considering various designing parameters at the designing stage and the distinguishments in the energy consumption, energy saving per year and CO2 emissions between conventional building and the designed prototype of NZE Green building are addressed.

Green building design refers to reducing the energy consumption of buildings through the use of energy-saving and environmentally-friendly technologies during the design and construction of buildings. The consumption of water resources and electric energy in office buildings is significantly higher than that of ordinary residential buildings, which has a greater impact on the environment during the construction process. Therefore, the use of green building design in the design of office buildings plays an important role in reducing building energy consumption. This article takes an office building in Chongqing as an example to explain the green optimization design and provide support for subsequent related constructions.
