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

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.

Building Engineering

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.

Abstract Urban residential buildings make large contributions to energy consumption. Energy consumption per square meter is most widely used to measure energy efficiency in urban residential buildings. This study aims to explore whether it is an appropriate indicator. An extended STIRPAT model was used based on the survey data from 867 households. Here we present that building area per household has a dilution effect on energy consumption per square meter. Neglecting this dilution effect leads to a significant overestimation of the effectiveness of building energy savings standards. Further analysis suggests that the peak of energy consumption per square meter in China’s urban residential buildings occurred in 2012 when accounting for the dilution effect, which is 11 years later than it would have occurred without considering the dilution effect. Overall, overlooking the dilution effect may lead to misleading judgments of crucial energy-saving policy tools, as well as the ongoing trend of residential energy consumption in China.

The Cost

The national systematic, social requirements for green building development are becoming more stringent. But from the standpoint of the builder, who would contract and implement such a business, such regulations can become a burden working against efforts to promote building. Due to the increase in the initial investment cost associated with green building development, the reality is that voluntary compliance is not readily forthcoming. Thereby, the profitability of green building construction was examined from a cost perspective for a 40-year life cycle cost. As a model example of green apartments, the A Apartment complex was analyzed for its economy. A comparison was made against a standard building for green building design on its initial investment cost, and the energy savings during the occupancy phase, required to offset the cost of investment was calculated. As a result, the A-Apartment investment cost recovery period was approximately 10 years, with about an 8% range of operating profit. If the green building construction business were to be pursued with this long-term view, it is evident that construction of green buildings can be good for business.
