Building Green <br />What is a "green building "? <br />• Comprehensive, "whole building" approach to designing, constructing, and operating a building <br />to reduce its environmental impact <br />• Results in far less waste and toxicity in the environment: <br />• No or very few composite materials <br />• No or very few materials that produce toxic waste or pollution during their manufacture <br />or construction <br />Considers life -cycle costs and eventual deconstruction of a building <br />Whole building design: <br />• Starts with the building envelope, orientation, massing and arrangement of spaces inside. <br />• The building envelope is designed as a filter to: <br />• Provide glare free daylighting <br />• Reject heat in the summer <br />• Retain heat in the winter <br />• Optimize Energy Performance —make the building do as much of the work as possible <br />• Maximize building exterior /interior insulation <br />Site and orientation <br />Primary East/West long axis (minimize East and West exposures) <br />• Shading devices on South elevation <br />• Maximize North glazing (windows) for daylighting —uses natural light to illuminate <br />buildings <br />I. Brings indirect daylight deep into a building <br />II. Connects people to the rhythms of nature while providing pleasing illumination <br />III. At a fraction of the cost of even the most efficient electric lights <br />IV. The most successful is known as "cool daylighting" because it reduces the need <br />for electric lighting and it reduces the need for cooling <br />Materials— recycled, natural or reused materials are optimum <br />• See what is available locally <br />• Natural cotton insulation (old blue jeans) <br />• Sound proofing (recycled shredded paper) <br />• Concrete mixed with incinerator ash <br />• 54% recycled- content carpet squares <br />• Waterless urinals <br />ICC 700 -2008 National Green Building Standard <br />ICC 700 -2008 National Green Building Standard provides valuable insight to the intention and <br />implementation of the practices and provisions found in the Standard. Developed with the input of <br />members of the ICC 700 -2008 Consensus Committee who developed the Standard, the Commentary is a <br />useful resource for any designer or builder using the ICC 700 -2008 as a rating system for developing or <br />renovating residential properties of all types to reduce their relative environmental impact. <br />The Commentary expands on the compliance language in the ICC 700 -2008, including: <br />Scope & Administration <br />
