Cement and chemical grouts have often been used for soil strengthening. However, high cost, energy consumption, and harm to environment restrict their applications. Biocement could be a new green building- material and energy-saving material. Biocement is a mixture of enzymes or microbial biomass with inorganic chemicals, which can be produced from cheap raw materials. Supply of biocementing solution to the porous soil or mixing of dry biocement with clayey soil initiate biocementation of soil due to specific enzymatic activity. Different microorganisms and enzymes can be used for production of biocement.

According to the principles that green sports building should follow are reducing environmental load and the amount of the utilized resource and energy. It emphasizes harmoniousness of architecture and environment. Started with green buildings concept, the necessity for developing green building is analyzed and its design rules are summarized. On the basis of that, the architecture of green sports building technology is presented according to the design idea of sports building and green building,. And sustainable utilization of green sports building is explored on resource, environment, energy-saving, after-use and so on. Then green design for manufacturing is referred to. Based on life cycle, green design for sports building is pointed out. At last, by using Analytic Hierarchy Process (AHP) method, assessment model is built and environmental performance in design phase of green sports building is assessed.

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.

Institute Of Technology

Sepuluh November Institute of Technology (ITS) encourages the ECO Campus program. The program enables ITS to systematically identify, evaluate, manage and improve their environmental performance and practices. One of the program issue is energy saving in building. The energy saving effect of an air-conditioning system retrofit project is analyzed by Energy Conservation Opportunities (ECOs) Method. These ECOs are assessed in terms of their costs and benefits, and an economic comparison to rank the various refrigerants. Finally, an Action Plan is created where certain ECOs are selected for implementation. Civil Engineering Department has a responsibility to design infrastructure and green building concept planning. This department also has the largest energy consumption in this faculty comparing the other department. The energy consumption on this Department is 60829 kWh/month. The value of IKE is 13.39 per month with the largest electrical energy consumption in air-conditioning system is 57% from total consumption. The energy used of air-conditioning sytem is 523.692 kWh. The energy saving opportunities by CFC retrofitting with hydrocarbon can save its power consumption about 20%. It also saving cost and reducing the electricity bill of 1643871.838 IDR/month. The payback period of investment costs of retrofit R-22 to Hydrocarbonis about 13 month.

Synthetic Evaluation

In this paper, evaluation index system of green building energy-saving technology was established on the basis of comprehensive analysis of the factors affecting green building energy-saving technology. This evaluation index system was divided into two levels. Thermal performance of maintenance structure, energy efficiency of building equipment, design management, operation management and indoor comfort and health were one-level evaluation index, and there are eighteen two-level evaluation indexes. Entropy weight method was introduced to determine the weight of evaluation index. Fuzzy synthetic evaluation method was applied to synthetic evaluation. On this basis, a model based on entropy weight method and fuzzy synthetic evaluation method was proposed to evaluate the green building energy-saving technology. An example was given to verify the validity and feasibility of the model. Results show that the model can used to evaluate the green building energy-saving technology, and offers reference on evaluation of green building energy-saving.
