Part A G|PRO Page 4
Sustainability A way of living (and working) that meets the needs of the present without compromising the ability of future generations to meet their own needs. -Brundtland Report, United Nations G|PRO Sustainability is the Key Page 5
Green Building A critical component of green building is its durability and how it performs over its entire life. Green Buildings: 1. Minimize adverse environmental impacts 2. Reduce energy and water consumption 3. Contribute to the health and productivity of both workers during construction and occupants after completion G|PRO California Academy of Sciences What is a Green Building? Page 39

CLIMATE CHANGE: CAUSES G|PRO Climate Change: Causes and Impacts Page 11
Weather vs. Climate Weather is the everyday state of the atmosphere – a combination of temperature, rainfall, humidity, cloudiness, and wind. Climate is the average weather pattern of one place over a period of time. The status of daily or weekly weather does not necessarily reflect climate trends. G|PRO
The Greenhouse Effect The greenhouse effect traps heat in the earth's atmosphere. In a greenhouse or a car, sunlight passes through the glass and warms up the inside. The heat can’t get back out through the glass and the greenhouse or car becomes hotter. G|PRO What is the Greenhouse Effect? Page 11
The Greenhouse Effect G|PRO What is the Greenhouse Effect? Page 11
The Earth Would Be a Ball of Ice Without the Greenhouse Effect Earth: Average Temp = 56 o. F Moon: Average Temp = -9 o. F G|PRO What is the Greenhouse Effect? Page 11

Why did this Warming Trend Start? Earth is getting warmer – at a faster rate since the Industrial Revolution. G|PRO What Caused this Climate Change? Page 12

CLIMATE CHANGE: IMPACTS G|PRO Climate Change: Causes and Impacts Page 11
What's Going to Happen? Small temperature changes matter. Business as Usual Controlled Growth Stop All Industry G|PRO Expected Impacts of Climate Change Page 14
What Does This Mean For Us? Expected Changes by 2050: • • Temperature rise of 3 – 5˚F Sea level rise of 7 – 12 inches 29 -45 days over 90˚F per year More heat waves, intense rains, coastal flooding, and severe droughts -New York City Panel on Climate Change G|PRO NYC During a Nor’easter

What About the Skeptics? • Over 97% of climate scientists agree climate change is occurring and is caused by humans. • But, millions of dollars have been spent by companies with vested interests to confuse the issue and prevent regulation that would reduce climate change. • Climate change skeptics create a false “controversy” by spreading doubt and confusion. G|PRO What About the Skeptics? Page 14
What’s the Downside Risk in Each Case? If the skeptics are right, but we act to alleviate climate change, we get: • Cleaner air and water • More efficient buildings • Less reliance on foreign energy If the skeptics are wrong, but we follow them and do nothing, we get: • 10°F temperature increase • Many feet of sea level rise • Droughts, floods, and other catastrophes G|PRO What About the Skeptics? Page 14
We all have a stake in keeping the environment healthy G|PRO The History of Environmental Protection Page 27
Environmental Protection The first national park was established in 1872 during the beginnings of the preservation movement. G|PRO How Environmental Protection Started Page 27
Environmental Disasters • Silent Spring (near extinction of bird species): 1962 • Cuyahoga River catches fire: 1969 • Love Canal: Late 1970 s Cuyahoga River, Ohio G|PRO Advocacy and Regulations Take Hold Pages 27 -28
Clean Air Act of 1970 has cleared the smog that once blanketed cities. CO 2 Steam Plant Scherer, shown here, is the largest single source for CO 2 emissions in the U. S. Coal-Fired Power Plant, Georgia G|PRO Air Pages 17 -18
Environmental Successes: Reduction of Acid Rain U. S. EPA Acid Rain Program: Cost to address acid rain was estimated by industry lobbyists at $1, 000 to $1, 500/ton. The actual cost, achieved by reducing sulfur dioxide emissions from power plants, was $250/ton! The reduced medical expenses exceed either cost. G|PRO Acid rain kills trees Pisgah National Forest, North Carolina Advocacy and Regulations Take Hold Pages 27 -28
We Can Solve It! • Large steps include regulations like the Clean Air Act: • Cap and trade limits on CO 2 emissions • National standards for building energy codes (now underway) • Improved mileage standards for cars and trucks (now underway) • Small steps, such as GPRO training, can be taken by individuals, companies, or municipalities: • Sustainable work practices • Efficient design pays for itself in savings • Training staff leads to safer, cleaner, more efficient operations G|PRO Don’t Wait for the Silver Bullet! Page 35
TEST YOURSELF: 1. What is the definition of sustainability? 2. Why is the design and operation of buildings so important in relation to sustainability? 3. What is global climate change, and how do greenhouse gases affect it? 4. What are the primary everyday threats to clean air? 5. What does the history of environmental laws tell us about the cost of cleaning up our emissions? G|PRO
