LOIS HOLE LIBRARY CERTIFICATION

LEED™ PROJECT SUMMARY

LOIS HOLE LIBRARY

Lois Hole Library was designed to reflect the extraordinary vision and philosophies of whom it was named after. As the 14th Lieutenant-Governor of Alberta, she was also a well recognized gardener and an avid supporter of public libraries. The building incorporates many features that reduce environmental impact and create a warm and inviting place that integrates with its natural surroundings.

With 2 nearby bus routes, 22 bike stalls and fewer parking spots, visitors and staff can easily commute without their own automobiles. By being situated in a sediment basin and utilizing drought-resistant vegetation along with a system of recycled rainwater captured from the roof, the need for irrigation is non existent. This recycled water is also used for toilets, urinals and other non-potable high efficiency fixtures that reduce the potable water by 60%. Topsoil from the pre-construction site was preserved for landscaping in later stages of construction and adjacent areas are protected as open space to prevent further development of the land. Furthermore, construction was kept limited as possible and sediment controls were put in place to keep site disturbances minimal.

Natural day lighting has been introduced throughout the building to provide lighting and the lighting system is controlled by sensors that indicate when sufficient day light is available. Sensors open and shut windows to maintain a temperature depending on the time of year. Exterior lighting has also been considered with permanent sun shades on the east and south faces to limit solar gain in the summer months and thereby reducing the requirements of the cooling system. From an energy and atmosphere perspective the library achieves efficiencies of nearly 50% over that of the Model National Energy Code for Building (MNECB) earning a generous credit optimizing energy performance.

The City of Edmonton brought into the equation a third party consultant to provide extensive review and inspection services that went above and beyond those provided by consultants during construction. With the future of the building in mind, monitoring systems were installed to ensure the ongoing optimization of the building energy and water performance.

Carbon Dioxide is continuously monitored and smoking in the building has been prohibited since the beginning of construction. During construction, an indoor air quality program was initiated to help sustain the well being of workers and building occupants. When construction came to a close, only environmentally friendly cleaning products were used for daily cleaning and maintenance operations to appease the Green Housekeeping Policy, which earned the Library credit for Innovation in Design.

Finally, waste management practices employed during construction ensured that nearly 100% if the waste was diverted from the landfill by redirecting recyclable resources back to the manufacturing process and by redirecting reusable materials to appropriate sites, which also achieved credit in Innovation and Design.
