This community building is located in the little town Huaibeizhuanjcun northeast of Beijing, China. It is based on the concept of integrating nature and community. The idea is to create a building that connects the commu-nity service building and the natural environments. The building is split into two. Half of the building is embedded in the ground while the other half sits on top. The embedded half will provide a li-brary, computer lab, and classroom space for the community. The other half will be where the services for the community will be conducted.The reason for earth-berming the building is two-fold. One, it symbolically allows nature to encroach seamlessly into the built environment. Second-ly, by embedding part of the building, the heating and cooling load of the building will be reduced due to thermal mass. On top of that it allows for the reuse of the earth that will be displaced due to construction. The roof of the embedded half will be a green roof. A geothermal heat pump is another sustainable strategy that is used. The geothermal heat pump will be installed during the process of embedding the building into the ground. It will help reduce the cost of heating and cooling of the building.

Pond used as Heat source/ sink

The building will utilize a hybrid system to heat and cool the interior spaces. The first system is a hybrid GHP (Ground Heat Pump) system. The GHP will exchange heat with the pond located on site. The second system is a closed water loop fan coil. The heated or cooled water from the GHP will circulate throughout the building and to the individual fan coil units. Each fan coil unit then will heat or cool the rooms. The third system is a fresh air intake system. It will have its own set of ducting and filters. This system is implemented because Beijing and its surroundings are highly polluted.

Typ. Fan Coil System

Given the fact that China’s and especially Beijing’s air quality is unhealthy. Indoor air quality becomes am important issue. Indoor air quality is affected by both outdoor and indoor pollutants. Some of the strategies of improving indoor air quality are: operable windows, vegetation, walk off matts, and the filters used in the HVAC system. Operable windows can be used to completely flush out the building on days that the outside air quality is decent. Vegetation both on the roof and around the site will help filter the air. The leaves will trap the pollutants which will then be washed off during storms. Walk off matts reduce the amount of debris that is tracked into the building from peoples shoes. The walk off matts will have to be cleaned regularly. The building will be using a fan coil system for its HVAC. Each fan coil unit will have it’s own filter built in. In addition to this though, there will be a couple of fresh air intake ducts that service the fan coil units that are not able to be placed against an exterior wall. These fresh air intake ducts will have their own set of filters.
