The Candler Library Renovation and Expansion project strived to think in new and innovative ways to design and construct a building which conserves energy, water and helped to preserve the natural environment. CH2M HILL worked with Emory and Candler
Library's design team to obtain
the highest Green Building Rating possible. The project achieved a SILVER LEED rating.
This building is served by Emory’s alternative transportation system which consists of clean burning natural gas and electric buses which reduces local emissions and result in a no net increase in vehicle parking. Occupants have access to eight bus routes available within a ¼ mile of the building. Bike racks and a changing/shower room were installed to support those who bike or walk to work.
Low flow aerators were added to water fixtures resulting in a 30% reduction in water consumption. This reduces the burden on municipal water supply and waste water systems.
Optimizing Energy Performance
Heating and cooling requirements were reduced by over 30% by careful selection of building system components, insulation and building automation and control devices. Energy savings were also realized by utilizing variable speed motors and occupancy sensors.
78% of the original building shell such as perimeter walls, marble cladding and roof trusses were retained as part of this project.
Recycling building materials
60% of the new building materials used in constructing Candler
Library were composed of recycled materials.
43% of the new raw building materials used in constructing Candler
Library were manufactured within 500 miles of the job
site thus reducing transportation costs and supporting the local economy. Over 50% of the locally manufactured materials were harvested regionally.
Low Volatile Organic Compound (VOC) Emitting Materials
VOCs contribute to outdoor smog generation and also have negative
health risks and impacts on building occupants. By using low VOC paints,
carpets, and adhesives, both outdoor and indoor air quality were
Fifteen thousand square feet of 1 1/2 " thick marble, weighing approximately
130 tons, was removed from the original Candler Library floors. The
marble is currently being stored on campus. Some of the marble was reused in Candler Library as signage plaques, computer kiosk surfaces,
Reading Room furniture tops, and accent walls. The remaining marble
will be used in future projects around campus.
Prior to construction, four nearby holly trees were relocated. The
holly trees were considered to have historic value because they were
planted by the late Woolford B. Baker, beloved professor of biology,
protector of Emory's natural resources, and namesake of the campus's Baker
Woodlands. The trees were an exceptional size and variety and
included two specimen Ilex latifolias and two Ilex opacas. The process for moving the trees (the largest weighed over six tons)
required hand-digging a rootball, wrapping the rootball with burlap,
lifting the tree from the ground using a crane, and moving it to a
new site for careful replanting. Although we didn’t earn an innovative credit for this process, it was an important aspect and goal of our project.
