Sitsang belongs to cold Region in china and heating energy consumption in winter is very large. There is fairly scarce petrochemical energy, and that the oxygen content in plateau section is lower, which makes combustion become insufficient, so the cost of conventional energy is considerably high. However, compared with other regions in china, the best advantage of Sitsang is that it possesses abundant solar energy resources.

The application of a ventilation system in a new building is a multidimensional complex problem that involves both quantifiable and non-quantifiable data e.g. energy consumption, indoor environment, building integration and architectural expression. This paper presents a structured method for evaluating the performance of a ventilation system in the design process by treating quantifiable and non-quantifiable datasets together.

Integral design shows high promises to reduce failure costs and to improve design quality. Based on this assumption, the Royal Institute of Dutch Architects (BNA), the Dutch Society for Building Services (TVVL) and Delft University of Technology (TUD) started a research project on Integral Design in year 2000, which resulted in a series of workshops for architects and HVAC consultants.

Concepts of sustainability in buildings and cities are many and there are various programmes for healthy cities and researches on indoor air quality. Wellbeing indoors depend on external factors also. The fourth skin or microbiosphere above the building envelope has not been studied well. Sustainable building or green building is being designed but such building functions well only in sustainable cities and often indoor air quality is creating sick building syndrome.

In recent years, there has been an increasing number of publications on the thermal and daylight performance of double skin facades in moderate climates. However, there is a scarcity of research on how different configurations of the cavity and its height can lead to an impact on internal cooling/ heating loads and the availability of daylight indoors in hot arid climates.

To realize a desirable building environment by saving energy and low global emission, the author has been investigating passive systems in buildings where the environment is controlled biomimetically and autonomously by simulating the physiological functions of human and other organisms. An environmental harmonized Biomimetic Building, which simulates the environment physiology mechanism of a human body and human wisdom for environment symbiosis, has been developed.

The trend to reduce energy losses through enclosures (walls and windows) is an increasingly important part of improving the energy efficiency of a building. Adequate window design and orientation can reduce the heating and cooling requirements of a building.

The need for higher productivity to match the growing competition has forced employers to look for better Indoor Work Environments. Since most of the buildings are being air conditioned, the Heating Ventilating and Air Conditioning (HVAC) systems account for nearly 40% of total building energy consumption. To reduce this energy consumption Thermal energy storage systems (TES) were developed. The Latent heat thermal energy storage (LHTES) systems using water/ice are commonly used for peak shifts in electrical demand.

There are about 16 millions building in Turkey. The total energy consumption of these buildings is approximately 3.48x105 GJ. The energy consumption of the office buildings having HVAC systems can be stated as 150 kWh/m2.year.Turkey is in the warm climate band and the day time outside air temperature in summer (May ~ September) is about 30C. Parallel to the increasing comfort demands, energy consumption also increases. These factors make the necessity for increasing energy efficiency of buildings apparent.

This paper describes the production of the Customer Advising Tool (CAT), a piece of software to help assess the potential for reducing the cooling demand of Office buildings, as required by Article 9 of the EPBD. It is a practical tool aimed at use by building owners, inspectors and auditors as part of the Inspection and Audit process. The tool was developed by the authors as part of the IEE AUDITAC project.
