Building selected for the Poster Presentation
Kwantlen University College Building, Surrey, B.C.
(Surrey), British Columbia
gross area: 4,330 m2
The mechanical plan consists of a geothermal field and water source heat pumps. Circulating pumps distribute the heating/cooling water throughout the building while the thermal storage capacity (mass) of the opaque elements stabilizes temperatures within the spaces. This provides a considerable reduction in cooling and heating energy requirements. By optimizing thermal mass in combination with nocturnal pre-cooling techniques, a significant portion of the cooling load can be provided. Internal mass has also be used to absorb heat during the day and release it at night. The effects of buoyancy, stack, and wind pressure provide three naturally occurring, reliable options for utilizing free wind energy. The lower two floors are fed with 100% out door air through operable windows and louvers. Abiding by the three natural effects listed above, the air will flow into the corridors on each floor , then into the atrium where it will be exhausted through the top, via a wind towers.
In addition, by supplying 100% outdoor air into the occupied spaces and exhausting/relieving polluted air without recirculation, superior air quality can be achieved within the building. CO2 levels will be monitored throughout the interior spaces, and ventilation intake dampers within the louver system will open if levels exceed set points.
The energy use of the mechanical system has been minimized
by employing natural/ wind driven ventilation, high thermal
mass usage, high performance envelope, other passive
heating and cooling concepts and highly efficient building
systems such as radiant slab heating and cooling with
