1 LEED Gold Woodward Academy Math-Science Building Leadership in Energy and Environmental Design

2 W A What is LEED LEED (Leadership in Energy and Environmental Design) is a voluntary, consensus-based, market­-driven program that provides third-party verification of green buildings. From individual buildings and homes, to entire neighborhoods and communities, LEED is transforming the way built environments are designed, constructed, and operated. Comprehensive and flexible, LEED addresses the entire lifecycle of a building. Participation in the voluntary LEED process demonstrates leadership, innovation, environmental stewardship and social responsibility. LEED provides building owners and operators the tools they need to immediately impact their building’s performance and bottom line, while providing healthy indoor spaces for a building’s occupants.

3 W A Why LEED? LEED-certified buildings are designed to: 1. Lower operating costs and increase asset value 2. Reduce waste sent to landfills 3. Conserve energy and water 4. Be healthier and safer for occupants 5. Reduce harmful greenhouse gas emissions

6 W A Stormwater Design (Quantity) The building site was designed to limit the disruption of natural hydrology by reducing impervious cover, increasing on-site infiltration, reducing pollution from stormwater run-off and eliminating contaminants.

7 W A Stormwater Design (Quality) Best Management Practices (BMP) have been used to capture and treat runoff from 90% of the average annual rainfall and are capable of removing 80% of the total suspended solids from the average annual rainfall post-development runoff.

8 W A Heat Island Effect An urban heat island (UHI) is a metropolitan area that is significantly warmer than its surrounding rural areas due to human activities (development). The temperature difference usually is larger at night than during the day and results from the absorption and storage of light as heat.

9 W A Heat Island Effect (Roof) Most of the roofs in the world (including over 90% of the roofs in the United States) are dark-colored. In the heat of the full sun, the surface of a black roof can increase in temperature as much as 90 °F, reaching temperatures of 158 to 194 °F. This heat increase can cause negative effects on cooling energy use and environments.

10 W A Heat Island Effect (Roof) The Math Science Building roof reduces the heat island effect by using materials on the low-slope roof with an SRI value above 78.

11 W A Water Use Reduction The building’s plumbing system was designed to reduce the use of potable water by the installation of low-flow faucet aerators and ultra-low flow urinals.

12 W A Water Use Reduction The calculations for this credit compare the minimum standards set forth by the Energy Policy Act and the usage of newer, more efficient fixtures. The calculated savings of this building was over 40%.

13 W A Optimize Energy Performance A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that pumps heat to or from the ground. It uses the earth as a heat source (in the winter) or a heat sink (in the summer).

15 W A Green Power Biomass is one of the largest domestic sources of renewable electricity in the United States. It provides more than 10,000 MW of power, which is: reliable economical and environmentally sustainable. Biomass material consists of organic matter available on a recurring or renewable basis: forestry trimmings, wood processing residue, urban wood waste and other wood waste. Biomass energy is a renewable energy source since the energy contained in organic materials comes from the sun.

17 W A Daylighting and Views Daylighting is the practice of placing windows or other openings and reflective surfaces so that during the day natural light provides effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Artificial lighting energy use can be reduced by simply installing fewer electric lights because daylight is present, or by dimming/switching electric lights automatically in response to the presence of daylight, a process known as daylight harvesting.

18 W A Daylighting and Views Buildings that provide views to the outdoors have proven to enhance productivity, testing performance, and overall occupant comfort and well-being.
