Energy Performance and Water Efficiency
This building achieved an impressive level of efficient energy performance by way of an integrated design approach and a close collaboration between the design and construction teams. It is expected to consume 45% less energy than a similar building constructed to the Model National Energy Code for Buildings. The primary factors responsible for the savings were the overall building design, the design of the mechanical and electrical systems, and the building
envelope system, including the reflective roofing material and high performance glass.
The City of Surrey also invested in Additional Commissioning for this public project to ensure that the installed systems perform to the standard specified in their design.
In terms of water efficiency, the facility earned 4 out of 5 LEED™ Scorecard points, with water savings features inside and out. The incorporation of waterless urinals (the first time they have been installed in a building owned by the City of Surrey) is expected to save annually some 160,000 litres of water each. Overall, water use was reduced by 30% compared to similar buildings constructed to the NEC Model.
Indoor Environmental Quality
The high standard of indoor air quality and thermal comfort achieved on this project is particularly noteworthy. The building’s design, especially the glazed atrium along the front (east) facade and the high ceiling on the second storey, works with a displacement ventilation system to provide very effective ventilation throughout the structure. Security requirements precluded openable windows, yet the overall distribution of fresh air and the comfort level are excellent — and the system is exceedingly quiet, an important factor for both the RCMP and the library functions. As an additional measure to ensure consistently good air quality, the client chose to invest in a carbon dioxide monitoring system for this facility.
Preference was given to low-emitting materials throughout, including adhesives, sealants, paints, and carpets. Behind the scenes, solid wood blocking (instead of plywood) was used to anchor all units that required wall mounting — a measure suggested by the constructors on site.
This project achieved credit for 10 out of 15 of the components of the LEED Scorecard for Indoor
Environmental Quality.
