    • Why We Need to Change Our Building Habits 1804 – 1927 1 to 2 billion people 1996 – 2008 6 to 7 billion people 1.
    • “ . . . buildings are the biggest source of energy use and greenhouse gas emissions , which in turn impact the world’s climate changes.” Green Building: Essential Design Strategies for a Sustainable Future Barbara A. Nadel, FAIA, Architectural Record, November 2006
    • “ Global warming is not caused by natural forces beyond our control. . . . human beings are the cause of the problem. And so it is our responsibility to fix it.” An Inconvenient Truth Al Gore Total Energy Use
    • Oil Dependence The Middle East holds 61% of the world's proven oil reserves.  North America has 5%.
    • Increasing Oil Demand Unless there is a dramatic effort to change our consumption, energy demand is expected to rise by nearly 20 percent by 2030 according to the Department of Energy. Source: Energy Information Administration
    • The amount of U.S. greenhouse gases flowing into the atmosphere , mainly carbon dioxide from burning fossil fuels, increased last year by 1.4 percent after a decline in 2006. Source: U.S. Energy Department Associated Press, 12/03/08
    • “ Carbon emissions have been growing at 3.5% per year since 2000 , up sharply from the 0.9 percent per year in the 1990s.” 02/15/09 EBN 09/09
    • 01/23/09
    • Climate Change Quickens, Seas Rise Global warming is happening faster than expected and at worst could raise sea levels by up to 6-1/2’ by 2100 according to a group of scientists. November 24, 3009

    • Green buildings are good for the environment, people, and they provide life-cycle cost savings. The Bottom Line:
    • #2 Incorporate Cost-Effective Green Building Strategies
    • 1. Sustainable Site
      • Avoid prime farmland
      • Channel development to urban areas with existing infrastructure
      • Rehabilitate brown-fields
      • Locate project within ½ mile of an existing or planned and funded public transportation system
      • Provide bicycle racks and shower facilities
      • Protect or restore habitat
      • Maximize open space
      • Reduce or eliminate water pollution by reducing impervious cover and increase on-site infiltration
    • Install Bicycle Racks
      • Provide bicycle racks for 5% or more of all building users during peak time
        • Reduce automobile use that contributes to air pollution
        • Reduce dependency on oil
        • Reduce impact of oil refining
        • Promote well-being
    • Drive Less Walk, bike, carpool or take public transportation more often. You’ll save one lb of CO2 for every mile you don’t drive. Your car will emit as much CO2 in a year as your entire household = 12,000 lbs.
    •  
    • walkscore.com
      • 90 – 100 = Walkers’ Paradise
      • 70 – 89 = Very Walkable
      • 50 – 69 = Somewhat Walkable
      • 25 – 49 = Car-Dependent
      • 0 – 24 = Car-Dependent (driving only)
      • Walk Score calculates the walk-ability of an address by locating nearby stores, restaurants, schools, parks, etc.
      • Walk Score measures how easy it is to live a car- lite lifestyle – not how pretty the area is for walking.
    •  
    • Provide Hybrid Parking
      • Intent: Reduce pollution and land development impacts from automobile use
      • Strategy: Provide preferred parking for low-emitting and fuel-efficient vehicles for 5% of the total parking capacity of the site
      • Example:
        • 200 parking spaces x 5%=10 preferred parking spaces
    • Heat Island Effect: Environmental Issues
      • The use of dark, non-reflective surfaces for parking, roofs, walkways and other surfaces contributes to heat island effects. As a result of heat island effects, ambient temperatures in urban areas can be artificially elevated by more than 10 degrees when compared with surrounding suburban and undeveloped areas. This results in:
        • increased cooling loads in the summer;
        • larger HVAC equipment;
        • increased electrical demand;
        • more greenhouse gas + pollution; and
        • increased energy consumption .
      Urban heat islands can maintain temperatures 6 – 8 degrees above that of surrounding rural land. EBN September ‘09
    • Heat Island Effect: Non-Roof
      • Use the following for
      • 50% of the site
      • hardscape:
      • Shade
      • Paving materials with a Solar Reflectance Index (SRI) > 29
      roads, sidewalks, courtyards and parking lots USGBC Sustainable Site, Credit 7.1
    • Paving Materials’ SRI Solar Reflectance Index (SRI) is the measure of a material’s ability to reject solar heat, as shown by a small temperature rise. Material Reflectance SRI New Gray Concrete 0.35 35 Weathered Gray Concrete 0.20 19 New White Concrete 0.70 86 Weathered White Concrete 0.40 45 New Asphalt 0.05 0 Weathered Asphalt 0.10 6

    • Make Your Roof “C-o-o-l”
      • Metal roofs can reflect up to 70% of the sun’s energy and reduce cooling costs by up to 20%
      • Reduce HVAC system size due to smaller peak cooling loads
    • Green Roofs
      • Reduces roof heat gain (Sunny 95 degrees, conventional roofs reach 175 vs green at ambient air temperature)
      • Reduces heat island effect
      • Reduces indoor sound by as much as 40 decibels
      • Reduces storm water runoff
      • Extends roof life, no u.v. rays
      • Energy conservation plants and 4 inches of growing medium reduce indoor temperatures 6 to 8 degrees and can reduce air-conditioning costs 25 to 50% in single story buildings
      • Live roof replacement every 20 years u.v. rays breaks down container/tray systems
      www.greenroofs.com
      • 4 Simple Way to Reduce the Heat Island Effect
      • Increase landscaping and shade from tree planting
      • Reduce paved surfaces
      • Incorporate roofing with reflective membranes or coatings
      • Install light-colored pavement and walkway surfaces
      • Less than 3 percent of the water on Earth is fresh;
      • much of that is unreachable in glaciers, ice-caps or deep in the earth.
      2. Water Efficiency`
    • Climate change will likely increase precipitation in some places while reducing it in others , particularly the West, where populations are growing the fastest. Environmental Building News, September 2008
    • Limit or eliminate the use of potable water for landscape irrigation.
      • “ The roughly 90 million lawnmowers, weed trimmers, leaf blowers, and other small-engine lawn and garden tools in the U.S. spew out approximately 5% of the nation’s air pollution , according to the U.S. Environmental Protection Agency.”
      • Environmental Building News , July 2005
      What’s Wrong With the Conventional Lawn?
    • Use Native Landscaping
      • Reduced air pollution
      • Reduced nutrient runoff, no fertilizer
      • Reduced pesticide use
      • Increased biodiversity
      • Lower annual operating costs
    • “ Some experts say that water may be an even more challenging problem than energy in the coming decades . . . ” Environmental Building News, September 2008
      • Lower Volumes of Potable Water
      • + Less Water for Water Treatment
      • Energy Savings and
      • Carbon Pollution Reduction
    • Reduce Water use by 20%-30%
      • Intent: Maximize water efficiency within buildings to reduce the burden on municipal water supply and waste water systems.
      • Strategy:
      • Use high-efficiency
      • fixtures and occupant
      • sensors to reduce the potable
      • water demand.
    • Greening Locker Rooms
      • Install fixtures high a high water efficiency
      • Provide touch-less fixtures
      • Purchase products with a longer lifecycle
      • Consider environmentally-friendly products
      • Purchase products with a high recycled content to conserve resources and prevent overflow in landfills
    • Low-Flow Showerheads
      • Aging showerheads using as much as 8 gallons per minute
      • Although the federal maximum is 2.5 gpm, models from Bricor, Delta, and Niagara offer satisfying showers with 1.6 gpm or a a 36% water savings over a 2.5 gpm showerhead.
    • Water Saving Fixtures
      • Toilet flushing is the largest single use of water in most buildings.
      • Zurn’s EcoVantage uses one pint, or 0.125 or 1/8 gallon of water per flush. They are all sensor-controlled (battery or hard-wired) and have a manual button override.
      • www.zurn.com
      1.28 gallons of water per flush
    • Four independent, real-world studies . . . have all shown that sensor-activated faucets increase water use by anywhere from 30% to 100% . Sensor-activated flushes on toilets and urinals also increase water use, due mainly to “phantom flushes ”. Environmental Building News – April 2009
      • 4 Simple Ways to Save Water + Costs
      • Use native and or drought resistant landscape
      • Use high-efficiency water fixtures
      • Use low-flow toilets + urinals
      • Consider automatic sensors
    • 3. Energy + Atmosphere Heating and cooling costs are generally the major expenses (30% - 35%) associated with the operation of a building. USGBC
    • Oil Prices and the Future
      • Prices will start to head up in Spring 2009
      • Drivers are taking to the road again . . . today’s low prices plant the seed of future hikes
      • By December 2009, the price per barrel will average $70 or $2 a gallon
      • 2010, growing oil consumption will push prices to $100 a barrel.

    • Thermal Energy (Ice) Storage
      • Benefit of shifting loads from daytime hours, when most cooling loads occur, to night-time, when electricity demand is lower and costs are often less.
      • Off-peak electricity generation is cleaner than peak energy.
      • Required space and height requirements adds to the building construction cost.
      • TES systems can reduce first costs by allowing chillers or packaged air-conditioners to be down-sized.
    • Saving Money with Off-Peak Electricity
    • Geo-Thermal Heat Pumps
      • Ground-source heat pumps (GSHPs), often called “geothermal heat pumps” exploit the relatively stable temperatures found below the surface, either depositing or extracting low-intensity heat.
      • Ground source heat pumps can be run in reverse to provide heating as well as cooling.
      • Large systems typically use drilled wells that may range up to 1,000 feet, using groundwater as the primary source of stable temperatures.
      www1.eere.energy.gov/geothermal
    • Future Electricity Costs?
      • The cost of fuel and electricity will soar, despite swift growth in alternative sources of energy, such as solar, geothermal, and wind power.
      • New regs will add 20% or so to electricity rates by 2020. . . and that’s over and above any increases anticipated from changes in supply and demand.
      • The average electricity cost for residential, commercial and industrial users may be 50% higher than today . . . more in areas such as the Midwest and Southeast, where coal fired power dominates. There . . . a 100% hike.

      • Formaldehyde-free binder
      • Contains no dyes
    •  
    • Solar Control Window Films
      • Window films from companies such as V-Kool and 3M are an excellent retrofit measure for reducing solar heat-gain
      • Films can filter out half the heat of sunlight while allowing most of the visible light through.
    • One-third or more of a building’s electrical consumption may go to lighting, and energy saved in lighting also reduces cooling loads. EBN April 2009 Replacing lamps, ballasts, luminaires, or all three, can lead to significant energy savings
    • Use colors of the same family to create tonal harmonies.
    • Changing a Light? Replacing one light bulb with a compact fluorescent light bulb will save 150 pounds of carbon dioxide a year The Energy Independence and Security Act of 2007 will phase out conventional incandescent lamps by 2014.
    •  
      • Replacing a 60 watt incandescent bulb with a 60 watt compact fluorescent lamp (CFL) results in a 75% energy savings. Reducing energy usage also reduces greenhouse gases from power plants. By using CFL you are having a positive impact on climate change.
      • Incandescent = 1,000 hours, 60 watts of energy used

    • Recycle, Reuse, Reduce Recycling 2 lbs saves 130 lbs of CO2 from the air. You can save 2,400 lbs of CO2 per year by recycling just half of your household waste. Recycle copy paper for printing on the other side. www.rcpworksmarter.com Rubbermaid Commercial
    • About 80% of what Americans throw away is recyclable, yet our recycling rate is only 28 percent. DoSomething.org 39% of waste in the average American household is paper. Paper made from virgin materials contributes to deforestation and global warming, and often ends up in a landfill. GreenAmericatoday.org
    • Recycling Saves Energy
      • Americans throw away 40,000 plastic bottles every minute. (19.2 million bottles in 8 hrs.)
      • Recycling doesn’t use more energy than making a new product.
      • Recycling aluminum saves 95% of energy use, plastic saves 60% – 75% and paper 55% – 75%
    • Recycled content refers to the portion of materials used in a product that have been diverted from the solid waste stream.

      • VOCs are carbon compounds that participate in atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate).
      • We learned that VOCs are any of those carbon-based compounds that smell strong and readily evaporate – items like acetone, rubbing alcohol and paint.
      • Paint
    • EBN, June 2007 Emissions of volatile organic compounds and other potentially toxic components from carpets have been widely recognized as an indoor air quality problem.

    • Carpet covers 70% of U.S. floors. EBN June 2007
      • Choose carpeting and carpet cushion that meet Carpet Rug Institute (CRI) Green Label Plus standards for emissions or better
      • Install carpet with low-VOC adhesive or use mechanical fasteners
      • Before purchasing carpet, ensure that the carpet can be recycled at the end of its life through an established program

    • Purge PVC From Your Life
      • Why? PVC is highly toxic throughout its life cycle, from manufacture to incineration. Potential hormone disrupters and other toxins can leach from PVC products, adversely affecting your health.
      • Action! Use the power of your wallet to send a message to companies that they need to stop manufacturing the “poison plastic.”
      • Spot It “Bad news comes in 3s”, refers to the number 3 recycling symbol displayed on many PVC products, especially packaging.
      • Building Approximately 75 percent of the PVC manufactured is used for building materials. Avoid vinyl windows and siding, plastic patio furniture, PVC-free recycled plastic lumber for decks and fences.
    • Avoid Formaldehyde
      • Two glues or binders dominate the manufactured wood products industry: urea formaldehyde (UF) and phenol formaldehyde (PF).
      • While UF binders are significantly less expensive than PF binders, they give a lot more formaldehyde – a volatile compound that is classified as a known hum carcinogen.
      • Formaldehyde’s other health impacts include respiratory problems; eye, nose and throat irritation; allergic reactions; and depression.
      • Rapidly Renewable Products
      • PlybooPure from Smith + Fong is the first bamboo flooring to carry Forest Stewardship Council (FSC) certification and is made with low-emitting, non-formaldehyde polyisocyanurate binder.

    • Many attributes of buildings that are being shown to improve human performance and productivity are also characteristics of green buildings:
      • Intent:
      • Provide for the building occupants a connection between indoor spaces and the outdoors . . .
      • daylighting,
      • views to the outdoors,
      • improved air quality, and
      • individual control of fresh air + comforts.
      Daylight + Views
    • Daylighting
      • Open layout
      • Clerestory windows
      • Skylights
      • Translucent panels
    • Daylight Harvesting Can Reduce
      • Amount of artificial lighting and its:
      • Associated energy costs
      • Related carbon emissions
    • Higher Costs = Change
      • Wal-Mart Supercenters and Sam’s Club stores have skylights with a surface area equal to about 3% - 5% of the floor area.
      • Energy savings are gained by using day-lighting (skylights and clerestories) and sensors to dim or turn off artificial lights when natural light is sufficient.
    • Provide Lighting Control
      • Intent:
      • Provide a high level of lighting system control by individual occupants or by specific groups in multi-occupant (i.e. classrooms or conference areas) to promote the productivity, comfort, and well-being of building occupants.
      Public Space Lighting Control
    • Workstation Lighting Control
      • Provision of individual controls for lighting can lead to increased occupant comfort by enabling occupants to tailor the workspace to their individual needs.
      • Additionally, by reducing ambient space foot-candle levels and providing user controlled, flexible, task-appropriate lighting, the project may reduce the overall lighting energy costs and reduce heat loads associated with high foot-candle levels of indoor lighting.
    • Provide Thermal Control
      • Intent:
      • To provide high level of thermal comfort system control by individual occupants or specific groups in multi-occupant spaces to promote the productivity, comfort and well-being of building occupants.
      • Strategies:
      • Active Conditioning (e.g. mechanical HVAC systems)
      • Passive Conditioning (e.g. natural ventilation)
      • Mixed-mode conditioning – employing a combination of active and passive systems
    • True or False
      • “ People are healthier in spaces that are less severely conditioned.”
      • True
      • Lawrence Berkeley National Laboratory, EBN, October 2009
      People get sicker in over-cooled and over-heated buildings. Cooler indoor temperatures in summer and warmer temperatures in winter consistently correlated with more health symptoms.
    • Operable windows may be used in lieu of individual controls for those occupants located within 20 feet of the exterior wall and within 10 feet of either side of operable window .

    • Does Green Building Have an Impact?
      • The equivalent of 2008 LEED water savings could fill enough 32 ounce bottles to circle the Earth 300 times.
      • By 2020, LEED energy savings will amount to more than 1.3 million tons of coal equivalent each year, representing approximately 78 million tons of carbon dioxide avoided emissions.
      • Certified projects to date have specified a total of more than $10 billion of green materials , which could grow to $100 billion by 2020.
