LL Location and Linkages Planning for LEED Civil Engineering and Architecture Unit2– Lesson 2.3 – Residential Design LL Location and Linkages Encourages the placement of homes in socially and environmentally responsible ways in relation to the larger community Courtesy Isle of Palms, SC Recreation Department Discourages the use of sites within fragile ecosystems and encourages development of sites that border previously developed land or building on a previously developed site. Credits are also available for sites that provide access to open space and allow walking, biking, and public transit to nearby facilities. ©iStockphoto.com Project Lead The Way, Inc. Copyright 2010

Planning for LEED Civil Engineering and Architecture Unit2– Lesson 2.3 – Residential Design SS Sustainable Site The use of the entire property to minimize the project’s impact on the site is encouraged Site developers are encouraged to minimize the disturbed area of the site and build at moderate or high density (i.e., put more houses in a given area). SS credits are also given for low impact landscaping and for minimizing the area of non-permeable surfaces. Project Lead The Way, Inc. Copyright 2010

Planning for LEED Civil Engineering and Architecture Unit2– Lesson 2.3 – Residential Design WE Water Efficiency Careful attention is given to promoting water conservation both indoor and outdoor Using captured rainwater or reusing “greywater” from home sinks and showers can provide a five point LEED credit. Using water-efficient irrigation and installing high efficiency shower heads, faucets, and urinals can greatly reduce water consumption in a building. Project Lead The Way, Inc. Copyright 2010

EA Energy and Atmosphere Planning for LEED Civil Engineering and Architecture Unit2– Lesson 2.3 – Residential Design EA Energy and Atmosphere Promotion of on-site renewable energy resources and maximization of energy performance help protect the environment and human health Reducing the need for natural energy resources helps reduce pressure on the environment. LEED credit is given to homes that exceed the ENERGY STAR performance requirements. Careful attention to insulation, air infiltration, window selection, heating and cooling systems, lighting , appliances, and water heating can greatly reduce energy consumption. Using renewable energy is also encouraged. Project Lead The Way, Inc. Copyright 2010

MR Materials and Resources Planning for LEED Civil Engineering and Architecture Unit2– Lesson 2.3 – Residential Design MR Materials and Resources Efficient use of environmentally preferable materials and minimizing the amount of waste during construction reduces negative impacts on the environment Credit can be obtained by minimizing waste, choosing environmentally-friendly materials, and finding other uses for construction waste.

IEQ Indoor Environmental Quality Planning for LEED Civil Engineering and Architecture Unit2– Lesson 2.3 – Residential Design IEQ Indoor Environmental Quality Reducing the creation of and exposure to pollutants can greatly improve the indoor air quality IAQ (indoor air quality) has a significant impact on the building occupants. The health of occupants should be of utmost concern for the owner of the building. With proper venting, moisture control, air filtering, and distribution of heating and cooling, the IAQ can be protected. Project Lead The Way, Inc. Copyright 2010

Green Building and Sustainable Architecture Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design Green Building and Sustainable Architecture During the design process, careful attention is given to building materials, construction methods, energy conservation, and the operational lifetime of the building. A green building, also known as a sustainable building, is a structure that is designed, built, renovated, operated, or reused in an ecological and resource-efficient manner. A responsible approach to environmental and human health Project Lead The Way, Inc. Copyright 2010

Sustainable Building Life Cycle Green Building and Sustainable Architecture Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design Sustainable Building Life Cycle Pre-Building Building Post-Building Pre-Building Phase How building materials impact the environment: harvesting trees could result in deforestation; mining mineral resources (iron for steel; bauxite for aluminum; sand, gravel, and limestone for concrete) disturbs the natural environment; even the transport of these materials can be a highly polluting activity, depending on their weight and distance from the site. The manufacturing of building products also requires energy and creates environmental pollution: for example, a high level of energy is required to manufacture steel or aluminum products. Building Phase The operation of the building life cycle considers natural resources, its carbon footprint, and operating costs. Post-Building Phase Old materials become resources for other building or waste to be returned to nature. The sustainable-design strategy focuses on reducing construction waste (which currently comprises 60% of the solid waste in landfills) by recycling and reusing buildings and building materials.

Green Building and Sustainable Architecture Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design Pre-Building Phase Site selection, building design, and building material processes, up to but not including installation. Examine the environmental consequences of the structure’s design, orientation, impact on the landscape, and materials used. Neighborhood and cities can benefit by proper planning. Consideration of water demands and building material during the planning phase. Creative architects and planners can use the natural resources provided by the building site.
