What looks like a giant glass pyramid is actually an envelope encapsulating four mixed-use towers. Parkview Green FangCaoDi
is a LEED Platinum certified project setting impressive sustainability standards in Beijing. Similar to a bio-dome, Parkview
Green makes use of a glass envelope to act as a buffer that helps reduce heating in the winter and protect the interior
against the summer heat. Designed by Integrated Design Associates, and engineered by ARUP, this hotel, shopping and
commercial hub is a massive project with a ton of other sustainable strategies.
Parkview Green FangCaoDi is a 800,000 sq ft mixed-use development and is quite possibly one of the largest sustainable
projects in the city. The collaborative design work of Integrated Design Associates and ARUP created a unique solution to
minimize energy use. The large glass pyramid structure encases two nine-storey and two 18-storey towers housing a office
space, a six-star hotel and retail facilities. The glass and ETFE envelope works to minimize heating and cooling in the
winter and summer. Specially designed louvers at the top allow hot air to escape and natural ventilation and free cooling
modes to be operated when outdoor condition is desirable. This buffer zone is a controlled microclimate in which the
temperature and humidity is relatively uniform and easily changed.
A geothermal system allows for energy-efficient heating and cooling when necessary. These hybrid passive and active
mechanical systems save 60% on cooling costs in the summer and 80% on heating in the winter. The development collects
rainwater from the roof and paved areas, which is then filtered and recycled for use as irrigation water. Waste water from
sinks, showers and washing faucets is also treated for flushing and landscape irrigation. Materials were chosen based on
their sustainability and the structure includes recycled materials from building demolitions for back-filling of the site and
steel. Quickly growing softwoods were used instead of hardwoods, and native plants and trees were selected for their low
water and low maintenance needs.
