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 Granoff Center’s anticipated energy use.  The building is estimated to use 26.3% 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 ten points can be awarded for improving the energy performance of a building compared to the existing standard, ASHRAE 90.1-2007. The Granoff Center is designed to earn 3 points for achieving energy cost savings of 29.5% compared to the baseline. The design team reduced the interior lighting power density and installed dimming systems for all lighting. They chose fiberglass insulation to reduce the amount of heat that escapes from the building. The walls of the Granoff Center have an R-value of 22, while the roof has an R-value of 50. The double-glazed windows are equipped with automated external Venetian blinds to control solar gain. Variable air volume air handling units provide more control of fan power air flow rates to each building zone. Furthermore, the green roof reduces the building’s contributions to the heat island effect.

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 Authority 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 Granoff 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.
