12/01/2009 Review Many considerations go into developing communities and building homes. One of the ideas to emerge recently is the idea of Green building. The focus of green building is to reduce the environmental effects of the building process. Green building includes using environmentally friendly materials and construction techniques. It also includes design decisions that reduce energy and resource use over the life of the house. A well-built green structure can be a win-win situation. Homeowners can get a well-designed, well-built structure that also has lower utility bills and helps the local economy.

12/01/2009 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. © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc

12/01/2009 Building Phase Construction and operation processes reduce the environmental impact of resource consumption Long-term health effects of the building environment on its occupants are considered Reduced energy consumption and the comfort of building occupants are two criteria that architects consider most during the life of the structure. © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc

12/01/2009 Post-Building Phase Old materials become resources for other buildings or waste to be returned to nature. The sustainable design strategy focuses on reducing construction waste by recycling and reusing packaging and excess material. The sustainable design strategy focuses on reducing construction waste (which currently comprises 60% of he solid waste in landfills) by recycling and reusing buildings and building materials. © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc

12/01/2009 Preservation of Natural Conditions An architect should minimize the impact of a building on its local ecosystem (e.g., existing topography, plants, and wildlife). The sustainable design strategy focuses on reducing construction waste (which currently comprises 60% of he solid waste in landfills) by recycling and reusing buildings and building materials. © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc

12/01/2009 Human Comforts A building’s design should enhance the work and home environments. This can improve productivity, reduce stress, and positively affect health and well being.
