This project is located in a campus which owns a large land, and has a good visual effect as a result of green plant throughout the year. This project has reached the second level of green building operation, and saves resources, protects the environment, reduces the pollution and has the very good environmental benefits of the whole life cycle. While saving energy and resources and providing economic benefits, it also provides a comfortable office environment for building users, and it also sets a reference for other similar office buildings in Inner Mongolia.
By adopting the design concept of low-carbon, green and ecological strategies, this project has achieved energy-saving, reduced influences to other buildings, and complied with national architectural policy. As a result of building energy-saving technologies (solar heating water system, ground source heat pump, natural ventilation, photovoltaic power generation), building water-saving technologies (water-saving implements and irrigating) and green lighting system, economy energy rate and unconventional water use reach 61.61% and 7.61%, respectively. 26.67% electricity use of the building is supplied by renewable energy power generation and 15.35% material is supplied by recycled building materials. Due to considerable energy saving, this project has become an actual energy-saving and low-carbon building, which provides an active and comfortable environment for undergraduate students. Also, this building has become a harmonious space of natural and humanistic, environment and life.

Owner approach of sustainability
This project adopts the design concept of low-carbon, green and ecological strategies and applies the following key technologies and products：solar heating water system， technology of rainfall penetration, sprinkler irrigation, thermal insulation of external wall, extruded polystyrene plate insulation material, aluminum alloy low-E hollow glass window, solar lamps, photovoltaic power generation technology. By adopting these integrated solutions, economy energy rate and unconventional water use reach 61.61% and 7.61%, respectively 26.67% electricity use of the building is supplied by renewable energy power generation and 15.35% material is supplied by recycled building materials.
1) Use of renewable energy
Graduate Building of Inner Mongolia Academy of agricultural & Animal Husbandry Sciences takes good use of solar heating water system, which achieves concentrated heat collection and heat storage affiliated by water-source heat pumps. Also, this project takes waste water as heating /cooling sources and applied photovoltaic power generation on façades and on the roofs.
2) Use of unconventional water source
There are lots of fields for seedling and planting and greenhouses in Graduate Building of Inner Mongolia Academy of agricultural & Animal Husbandry Sciences. The artificial green space can collect natural rain water to make greening irrigation without special artificial curing. According to the irrigating requirements of water quality, rainfall can be recycled directly after collection. As a bare grand, planting fields can not only collect rainwater for irrigation, but also have the effect of increasing rainwater infiltration and conserving groundwater.
Building users opinion
The user of this project has a good living experience, and the main living room near the window has better lighting effect. The performances of ventilation of different house types are great and the distribution of air flow is also perfect. Some secondary areas of this project have poor ventilation performance due to the obstruction of internal wall, and the air age is higher in some areas with less personnel activities such as corridors. It is a solution for these areas to close windows in transition season to achieve adequate air age and create comfortable living environment. The indoor temperature is controlled by intelligent control and can be adjusted flexibly based on requirements. The sound insulation the enclosure structure performs well, and the indoor acoustic environment meets the requirements of standard.

Sewage dedicated heat pump unit
It can be used to provide heating or cooling for the terminal systems in the building.
Product function: It achieves heat transfer in untreated sewage and media to gain or release heat to the waste water.
Innovation highlights: The cold - media switching technology is applied to ensure that the sewage can be directly entered into the heat pump to heat effectively. The theory of normal water source pump is to achieve heat exchange through water. Thus, waste water will pollute the heat pump when switching the water path. This product can introduce waste water into heat pump system directly to finish heat transfer process. In this way, it can avoid secondary pollution and this product has achieved national patent.
Switching between heating and cooling modes can be achieved by controlling valves. The main body of the system is made from admiralty brass to improve the corrosion resistance of the heat pump. Imported compressor and special jet pump are applied in this system to avoid jam and leakage of the system. By using independent oil supply path, the system performs conveniently and effectively.
