The Leadership in Energy and Environmental Design (LEED®) Green Building Rating System represents the U.S. Green Building Council’s effort to provide a national standard for what constitutes a “green building.” Through its use as a design guideline and third-party certification tool, it aims to improve occupant well-being, environmental performance and economic returns of buildings using innovative practices, standards and technologies.
To receive LEED certification, building projects must satisfy a number of prerequisites and earn points to achieve different levels of certification.
Some of the areas where Central Library will gain LEED points
Existing Building Reuse
By reusing our existing structure, the library will gain LEED credits allotted for projects that maintain the existing building structure including structural floor and roof decking, and its envelope, which is the exterior skin and framing.
Parking for Fuel-Efficient Cars
The new parking facility will offer preferred parking for low-emitting, fuel-efficient cars.
A stormwater management plan will allow the library to infiltrate, collect and reuse runoff or evapotranspiration to irrigate the garden and surrounding landscaping.
The library will offer bicycle parking near the coffee shop’s patio at Denver Avenue and near the entrance to the parking garage on Fifth Street.
Pervious Concrete Pavers
Used along the entire Fifth Street entrance, pervious pavers are an effective tool to capture stormwater into the library’s stormwater collection system to be used to irrigate the surrounding landscaping.
Healthy Environment – Low VOC
Low Volatile Organic Compound (VOC) paints, sealants, adhesives and cleaners will be used throughout the building to remove harmful chemicals out of the supply chain thus having a tangible impact on the health of building’s indoor air quality and improving the conditions inside for occupants.
Central Library will use an energy-efficient air distribution hybrid chilled beam HVAC system. The induction-activated chilled beams require only enough ducted air to handle ventilation and humidity requirements. This system will keep ductwork sizes to a minimum and allow ceiling spaces to remain high. Chilled beams use chilled and hot water as the main energy transport, thus improving overall HVAC efficiency compared to a traditional air heating/cooling system.
Throughout the library, ceiling-mounted lights will operate with daylight harvesting sensors that automatically will dim lights in response to changing daylight availability, thus not overlighting an area and reducing energy consumption. Also, each area will contain its own occupancy sensor to avoid using lights when the space is vacant.
The library also will feature lower shelving throughout the building to bring in more sunlight from existing windows.
The lower shelving at Librarium will be used at Central Library.
Cantilevered light fixtures attached to book and media shelving will focus light where it’s most needed – on the book/media covers and spines so that customers can see the titles more easily.
These examples of stack lighting are from Madison (Wis.) Public Library before they reopened their renovated Central Library. Notice there are few ceiling-mounted lights in the stacks, but a customer can easily view the contents of the stacks due to the cantilevered light fixtures.
