Transcript of Green Building
have minimal environmental impact
throughout the entire building life-cycle. Fundamental Principles Optimize Site Potential Proper site selection Locate in areas of existing development or Renovate existing buildings Control Erosion Through Improved Landscaping Practices Reduce, Control, and Treat Surface Runoff Consider Energy Implications in Site Selection and Building Orientation Reduce Heat Islands Using Landscaping and Building Design Methods Minimize Habitat Disturbance Restore the Health of Degraded Sites Design for Sustainable Transportation Balance Site Sustainability with Site Security/Safety Optimize Energy Use Reduce heating, cooling, and lighting loads through climate-responsive design and conservation practices. Employ renewable energy sources. Specify efficient HVAC and lighting systems. Optimize building performance and system control strategies. Monitor project performance. Protect and Conserve Water Reducing water consumption and protecting water quality are key objectives of sustainable design Use water efficiently Protect water quality Recover non-sewage and graywater for on-site use Establish site-based treatment and recycling programs Use Greener Materials Use of greener materials and processes that do not pollute or unnecessarily contribute to the waste stream, do not adversely affect health and do not deplete limited natural resources. Using a "cradle-to-cradle" approach, the "waste" from one generation can become the "raw material" of the next. Salvage and utilize existing facilities, products and equipment whenever possible Evaluate the environmental preferability of products using lifecycle thinking and lifecycle assessment (LCA) When new materials are used, maximize their recycled content, especially from a post-consumer perspective Specify materials harvested on a sustained yield basis Encourage the use of recyclable assemblies and products that can be easily "de-constructed" at the end of their useful lives Limit construction debris, encourage the separation of waste streams, and encourage recycling during the construction process Eliminate the use of materials that pollute or are toxic during their manufacture, use, or reuse Give preference to locally produced products and other products with low embodied energy content Enhance Indoor Environmental Quality Facilities should be constructed with an appreciation of the importance of providing high-quality, interior environments for all users. Includes indoor air quality, as well as other health, safety, and comfort issues such as aesthetics, potable water surveillance, ergonomics, acoustics, lighting, and electromagnetic frequency levels Facilitate quality IEQ through good design, construction, and operating and maintenance practices Value aesthetic decisions, such as the importance of views and the integration of natural and man-made elements Provide thermal comfort with a maximum degree of personal control over temperature and airflow Supply adequate levels of ventilation and outside air for acceptable indoor air quality Prevent airborne bacteria, mold, and other fungi, as well as radon, through building envelope design that properly manages moisture sources from outside and inside the building, and with heating, ventilating, air-conditioning (HVAC) system designs that are effective at controlling indoor humidity Use materials that do not emit pollutants or are low-emitting Assure acoustic privacy and comfort through the use of sound absorbing material and equipment isolation Control disturbing odors through contaminant isolation and removal, and by careful selection of cleaning products Create a high-performance luminous environment through the careful integration of natural and artificial light sources Provide quality water Optimize Operational
and Maintenance Practices Buildings must be operated and maintained with the security, safety, health, comfort, and productivity of their occupants in mind, and with an understanding of the next generation's need to reuse and recycle building components. Train building occupants, facility managers, and maintenance staff in sustainable design principles and methods Purchase cleaning products and supplies that are resource-efficient, bio-degradable and non-toxic Use automated monitors and controls for energy, water, waste, temperature, moisture and ventilation Reduce waste through source reduction and recycling to eliminate disposal off-site Minimize travel by supporting telecommuting programs and enabling teleconferencing Latest Developments YAHOO! has a state-of-the-art data center in Lockport, New York, featuring several long, heavily ventilated sheds to encourage natural airflow. Less than 1 percent of the building‘s energy consumption is needed to cool the facility, which has been aptly nicknamed the “Yahoo! Chicken Coop.” Ventilation & energy saving The 2.65-acre site surrounding the Center for Sustainable Landscapes (CLS) at the the Phipps Conservatory and Botanical Gardens in Pittsburgh is still being installed. However, once complete, the landscape will help the 24,000-square-foot building satisfy its water needs without relying on external sources other than rainwater. Site selection & self-sufficiency Sections of the screens surrounding Al Bahar Towers are computer-controlled to respond to the sun's movement, unfolding like umbrellas when the sun hits them.
