Sustainable-design principles put into action in today's education institutions.
Centre College, Pearl Hall — Danville, Ky.
Architect: Hastings & Chivetta Architects
What considerations were given to green products and processes?
To facilitate a team approach, an eco-charrette was held at the beginning of the design process, attended by the design team and Centre College stakeholders. The group discussed sustainable strategies and how they could be integrated into the project. Insight was provided relative to the applicability of each particular credit of the LEED rating system and how these strategies could achieve points. The overall objective was not to "chase LEED points," but rather to develop a collaborative effort that enabled attendees to come to consensus on the most practical and applicable strategies.
What are some unique green aspects of the facility?
Pearl Hall is the first building in Kentucky to receive LEED gold certification. One of the most important initiatives for this project was drilling a geothermal-well field of 65 wells drilled 300 feet deep for the ground-source heat-pump system. Ground temperatures of 50° to 55° degrees are used to heat and cool the hall, reducing carbon-dioxide emissions and eliminating the need for exposed roof-level cooling units. During the winter months, when the subsurface is warmer than the air above ground, the system transfers heat upward. During summer months, the heat is transferred down. Other green elements include energy-saving HVAC, individual temperature controls, efficient windows, regionally procured materials, materials made of recycled content and with low- or no VOCs, energy-efficient lighting, water-saving plumbing fixtures and water-efficient landscaping.
Doing the math
The 2 percent initial added investment (based on construction cost) will realize a 20 percent life-cycle savings, as well as have a positive impact on the environment and the quality of life for Centre College students.
