Sustainability: Building Energy Use
Atelier Ten
In determining the potential energy reduction for the planned building program, the regional
average energy use intensities from the Commercial Buildings Energy Consumption Survey (CBECS)
were used to determine a Baseline energy use. Up to a 60-70% energy savings can be achieved
through a combination of strategies including commissioning for existing buildings, upgrades to
HVAC systems and lighting, improving existing facades, upgrading the central plan equipment
and incorporating renewable energy technologies.
Energy Conservation
The redeveloped campus will
utilize and improve on the existing
infrastructure of the existing buildings
and central plant. The first step in
identifying and providing significant
energy savings is by commissioning
existing buildings. Commissioning will
be able to identify areas in which the
buildings are under-performing, and
provide suggestions for improvements
in HVAC systems, lighting, building
facades and overall operation of the
buildings. Benefits of commissioning
will have the greatest impact on
energy savings for existing buildings
efficiency by 35-40% after all the HVAC, lighting and facade improvements are implemented. 1
The central plant on the Gates campus has been well maintained and has more capacity than is
needed for the new programmatic uses. As the infrastructure ages, the long term replacement plan
will focus on selecting high-performance systems such as condensing boilers and efficient chillers.
An additional 10-15% in energy savings can be expected with upgraded central plant systems.
Renewable Energy
In Phase I, the large roof areas of the existing structures,
particularly on the parking garages and diagnostic and
treatment roofs, can be utilized to generate electricity for
building use with photovoltaic (PV) panels. In addition to
generating electricity the PV panel can work as a canopy to
provide shade to the public spaces below.
Additionally, solar evacuated tubes could be used for the
residential buildings proposed for Phase II. Solar evacuated
tubes use solar energy to provide domestic hot water to the
building for showers and other household uses.
The project will also evaluate the potential for integrating
vertical axis wind turbines. Gates is well located to take
advantage of wind given the taller building heights on campus
and low-rise rise residential neighbourhood surrounding the
campus does would not interfere with wind patterns.
