3. ProgramDesign Intent
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.

Air Quality
Air quality is measured by
the AQI (Air Quality Index)
It measures the amounts of
various pollutants in the
air:
-PM2.5: Airborne particles
less than 2.5μm in diameter
-PM10: Airborne particles
less than 10μm in diameter
-O3: Ozone Levels
-NO2: Nitrogen Dioxide
-SO2: Sulfur Dioxide
-CO: Carbon Monoxide

Air Quality
“In the past 24 hours, Beijing’s real-time air quality
index (AQI) reached 400 micrograms per cubic me-
ter, a level that results in serious risk of adverse respi-
ratory effects in the general population..... The World
Health Organization (WHO) deems anything over 25
micrograms per cubic meter as unsafe.”

16. Indoor Air Quality
Vegetation Filtration
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.

Typ. Green Roof Section
Given China’s ecological situation, sustainability is a key factor in any
design. For the community building I decided that using green roofs and SIPS
panels would be a must. The green roofs will provide several benefits. First it
will act as a thermal insulator for the building. Second, it will absorb rain, thus
reducing storm runoff from the site. Finally, the vegetation will help filter the air
around the building. The SIPS panels will provide better insulation for the roofs
it is used on thus reducing the heating and cooling load and saving energy.

18. The HVAC system that will be used in the building will be a Hybrid GHP
(Ground Heat Pump) system. The Hybrid GHP will tie into a closed water loop
fan coil system which will provide the heating and cooling for the spaces.
