Various engineering strategies were employed and integrated in our design to improve the library’s energy performance, energy efficiency, water efficiency, and its effect on the surrounding atmosphere. Our strategies include:
• High performance glazing- energy efficient windows comprised of triple glazing, specialized transparent coatings, and insulating gas sandwiched between panes, and glazing system with glare reducing frit patterns were used for the building’s current wall façade. This allowed us to maximize the use of natural day lighting whilst reducing the thermal solar heat gain within the space.
• Lighting control- occupancy and vacancy sensors limit the use of artificial lighting when not required. Dimming ballasts will be specified in circulation and perimeter reading areas with daylight responsive controls.
• Solar Shading – a brise soleil was used to prevent our glass façade from overheating during the daylight hours but also to allow natural lighting to enter the library space.
• Solar Energy- solar panels on the roof were used as an active solar technique to produce electricity and limit outside electricity consumption. Two passive solar techniques used were directing the library’s orientation and the panels south. This maximizes solar radiation received since the library is located in the northern hemisphere.
• Energy Efficient Appliances- highly efficient energy star rate equipment were used inclusive of computer, iPads, copiers, display screens, and printers. • Water Efficient Appliances- water use reduction strategies were employed by using low flow plumbing features inclusive of water closets, urinals, and lavatories. This conserves clean drinking water from being wasted.
• Regenerative Elevators- Elevators that capture mechanical energy from braking and convert that energy into electrical power.
