CMGT – Green Building Principles and LEED Certification Class 1 -380 Green Building Basics - Notes Department of Construction Management Ƈ California State University, Chico Discussion #2 – Green Building green building encompasses planning, design, construction, operations, and ultimately end-of-life recycling or renewal of structures. Green building pursues solutions that represent a healthy and dynamic balance between environmental, social, and economic benefits. sustainability meeting the needs of the present without compromising the ability of future generations to meet their own needs. (Brundtland Commission) Green Building Planning Design Construction Operational Practices End-of-Life Recycling or Renewal of Structures Is Green Building Important? Impacts of the Built Environment: x Land Use x Habitat x Natural Resource Consumption x Pollution x Energy Use x Water Use x Waste Generation x Vehicle Use Dynamic Balance between Environmental, Lower Impact More Sustainable In the U.S. Buildings Account for: Social, and Economic benefits. Triple Bottom Line People (social capital). All the costs and benefits to the people who design, construct, live in, work in, and constitute the local community and are influenced, directly or indirectly, by a project Planet (natural capital). All the costs and benefits of a project on the natural environment, locally and globally Profit (economic capital). All the economic costs and benefits of a project for all the stakeholders (not just the project owner) 1

passive design planning with the intent of capturing sunlight, wind or other natural forces for light, heating, and cooling. Passive Solar Design Also called climatic design, a design approach that uses structural elements of a building to heat and cool a building without the use of mechanical equipment. Passive solar design calls for careful consideration of factors such as local climate and solar energy resources, building orientation, and landscape features. The principal elements of passive solar design include proper building orientation, proper window sizing and placement and design of roof overhangs to reduce summer heat gain and ensure winter heat gain, and proper sizing of thermal energy storage mass (for example, masonry tiles). The heat is distributed primarily by natural convection and radiation, though fans can also be used to circulate room air or ensure proper ventilation. Unlike active solar heating systems, a passive design does not involve the use of mechanical and electrical devices, such as pumps, fans, or electrical controls, to circulate the solar heat. Buildings designed for passive solar incorporate large south-facing windows and construction materials that absorb and slowly release the sun's heat. The longest walls run from east to west. In most climates, passive solar designs also must block intense summer solar heat. They typically incorporate natural ventilation and roof overhangs to block the sun's strongest rays during that season. Daylighting takes advantage of natural sunlight, through well-placed windows and specialized floor plans, to brighten up a building's interior. Passive solar design can be used in most parts of the world. If designed by an experienced passive solar architect, buildings using passive solar design principles need not cost more up front than conventionally designed buildings. And when they do, the savings in energy bills quickly pay for themselves. daylighting the controlled admission of natural light into a space, used to reduce or eliminate electric lighting. 2

LEED applies to a wide range of commercial building types as well as residential structures. It addresses the complete building life cycle. from design and construction to operations and maintenance. tenant fitout. and significant retrofit. LEED for Neighborhood Development extends the benefits of green building beyond the footprint of a structure and into the broader community it serves. Greenhouse Gas Emissions http://www.epa.gov/climatechange/emissions/index.html “Gases that trap heat in the atmosphere are often called greenhouse gases. This section of the EPA Climate Change Site provides information and data on emissions of greenhouse gases to Earth’s atmosphere, and also the removal of greenhouse gases from the atmosphere. For more information on the science of climate change, please visit EPA's climate change science home page.” carbon footprint a measure of greenhouse gas emissions associated with an activity. A comprehensive carbon footprint includes building construction, operation, energy use, building-related transportation, and the embodied energy of water, solid waste, and construction materials. carbon neutrality projects that emit no more carbon emissions than they can either sequester or offset. The built environment, including buildings and transportation systems, accounts for more than two-thirds of all greenhouse gas emissions. Greenhouse gas emissions come from many components of the built environment, including building systems and energy use, transportation, water use and treatment, land-cover change, materials, and construction. By improving the efficiency of buildings and communities, we can significantly reduce greenhouse gas emissions. Carbon emissions provide a useful metric for many aspects of green buildings and communities, including energy, water, solid waste, materials, and transportation, but green building involves more than reducing greenhouse gas emissions. It is important to set goals for other issues as well, such as indoor air quality, healthy communities, and habitat protection. This comprehensive goal-setting process encourages programs and policies that will lead to sustainable communities. Climate Change http://www.epa.gov/climatechange/index.html “Climate change is a problem that is affecting people and the environment. Greater energy efficiency and new technologies hold promise for reducing greenhouse gases and solving this global challenge. EPA's website provides information on climate change for communities, individuals, businesses, states, localities and governments.” 4
