According to the U.S. Department of Energy, buildings use approximately 39% of the energy and 74% of the electricity produced annually in the United States. The building industry therefore represents a significant opportunity for energy reduction and efficiency improvements. In the U.S., most electricity is generated by burning fossil fuels. Their combustion releases carbon dioxide and other greenhouse gases that contribute to climate change and air pollution. Green buildings are designed to reduce the amount of energy required for building operations and maintenance. There are four components to optimizing a building’s energy performance: reducing the energy demand, improving energy efficiency of mechanical systems and appliances, using renewable energy, and verifying ongoing energy performance. A well-designed building not only minimizes carbon emissions, but will have lower operating and energy costs over the course of its lifetime.

Prerequisite 1: Fundamental Commissioning of Building Energy Systems: Prerequisite 1 requires all project teams to designate a commissioning authority to lead, review, and oversee the commissioning process.  A commissioning authority is in charge of reviewing the owner’s project requirements  and the design team’s basis of design to ensure that all energy-related systems are installed properly and are in compliance with the original requirements.  Energy-related systems include all heating, ventilating, air conditioning and refrigeration systems; lighting and daylight controls; and domestic hot water systems.

Prerequisite 2: Minimum Energy Performance: Prerequisite 2 requires that all new buildings must demonstrate that they use 10% less energy than a similar baseline building constructed according to the standards stipulated by ASHRAE 90.1-2007, which provides the benchmark for commercial building energy codes in the U.S. The design team used the energy simulation program, EQuest, to calculate the Aquatics Fitness Center’s anticipated energy use.  The building is estimated to use 30.29% less energy than the baseline.  These energy savings fulfilled EA Credit 3, as well as EA Prerequisite 2.

Prerequisite 3: Fundamental Refrigerant Management: The building heating, ventilation, air conditioning and refrigeration systems do not use any chlorofluorocarbons (CFCs) as refrigerants.  CFCs cause depletion of the ozone layer and contribute to global warming.

Credit 1 - Optimize Energy Performance: Up to nineteen points can be awarded for improving the energy performance of a building compared to the existing standard, ASHRAE 90.1-2007.  The Aquatics Fitness Center was designed to earn 10 points for achieving energy cost savings of 30.29% compared to the baseline.  The design team reduced the annual lighting energy use by 20%, the pool heating by 39%, the space heating by 43%, the cooling by 39%, the vent fans by 6%, and the domestic hot water by 4%.

Credit 2 - On-Site Renewable Energy: The system is composed of 168 hybrid modules. Each module is a pair of panels: a photovoltaic (PV) solar panel atop a patented thermal panel. Under full sun, the system will produce enough energy to light the building and heat the million-gallon swimming pool inside. Traditional energy sources will supplement the system on cloudy days. Approximately 1.97% renewable energy (470KW) will be generated on an annual basis.

Credit 3 - Enhanced Commissioning: Buildings that do not perform as designed will consume more resources over their lifetimes. Commissioning can verify that the building is operating as intended, and minimize its environmental impact. Facilities Management has contracted a Commissioning Agent to help review construction documents, develop a systems manual, and review the operation of the building within ten months of occupancy.

Credit 4 - Enhanced Refrigerant Management: Many refrigerants traditionally used in heating, ventilating, air conditioning, and refrigeration (HVAC&R) systems cause ozone depletion if released into the atmosphere or contribute to greenhouse gas emissions and climate change. Refrigerant management strategies include: designing buildings and selecting equipment that does not need chemical refrigerants; making sure HVAC&R systems run efficiently; choosing environmentally preferable refrigerants; and maintaining equipment to reduce leakage. The Aquatics Fitness Center design team selected refrigerants and equipment that minimize the emission of compounds that instigate ozone depletion and climate change. Their total life cycle ozone depletion potential and direct global warming potential is under the limit specified by LEED.

Credit 5 - Measurement and Verification: The project team has committed to share whole-building energy and water use data by entering it into the Energy Star Portfolio Manager.
