1 Sustainable Buildings and Green Markets
An Engineering Perspective Presented by: Haven Alford

2 Overview Why does it matter Elements of Sustainable Buildings
Government Application (Green Market Incentives)

3 Environmental Impact of Buildings (why does it matter
Environmental Impact of Buildings (why does it matter?) US Commercial Buildings Facts: 65.2% total US electricity consumption > 36% total US primary energy use 30% total US greenhouse gas emissions million tons of US construction/demolition waste (about lbs/person/day) 12% of potable water in the US 40% (3 billion tons annually) of raw materials used globally

4 5 Broad Areas of Application
Sustainable Sites Energy and Atmosphere Indoor Environmental Quality Water Efficiency Materials and Resources

5 LEED Concept and Intent
LEED is the standard for sustainable design worldwide. Design and construction practices that significantly reduce or eliminate the negative impact of buildings on the environment. LEED is a point based system that ranks the sustainability of a building’s design by: Certified (26 – 32 points) Silver (33 – 38 points) Gold (39 – 51 points) Platinum ratings (52 – 69 points)

6 Why engineers (and you) should care…
Discipline: MEP 28 points 41% Architect/LA % Civil % Constructor 4 6% Undefined 5 7% Totals 69 points 100%

7 Sustainable Sites Site Selection Development Density
Brownfield Redevelopment Alternative Transportation Public Transportation Bicycle Storage and Changing Rooms Alternative Fuel Vehicles Parking Capacity Reduced Site Disturbance Storm Water Management

8 Alternative Fuel Vehicles

9 Sustainable Sites Reduced Site Disturbance Storm Water Management
Protect or Restore Open Space Development Footprint Storm Water Management Rate and Quantity Treatment Heat Island Effect Non-Roof Roof Light Pollution Reduction

10 Green Roof se/stormwater.htm

11 Light Pollution

12 Water Efficiency Water Efficient Landscaping
Reduce by 50% No Potable Use or No Irrigation Innovative Wastewater Technologies Water Use Reduction 20 – 30%

13 Waterless Urinals and Composting/Waterless Toilets

14 Energy and Atmosphere Fundamental Building System Commissioning
Minimum Energy Performance CFC Reduction in HVAC&R Equipment Optimize Energy Performance Renewable Energy 5 – 10% Additional Commissioning Ozone Protection Measurement and Verification Green Power

15 Example of Natural Ventilation

16 Renewable Energy

17 Photovoltaic Roof Systems

18 Materials and Resources
Storage and Collection of Recyclables Building Reuse Maintaining 75 – 100% of Existing Walls, Floor, and Roof Maintain 100% of the shell/structure and 50% of non-shell/non-structure Construction Waste Management Divert 50 – 75% from a landfill Resource Reuse 5 – 10% of materials used are salvaged, refurbished, or reused materials, products and furnishings

19 Materials and Resources
Recycled Content 5 – 10% (post-consumer + ½ post-industrial) Regional Materials 20% manufactured regionally 50% extracted regionally Rapidly Renewable Materials Certified Wood

20 Recycled and Rapidly Renewable Materials

21 Indoor Environmental Quality
Minimum IAQ (Indoor Air Quality) Performance Environmental Tobacco Smoke Control Carbon Dioxide Monitoring Ventilation Effectiveness Construction IAQ Management Plan During Construction Before Occupancy

22 Indoor Environmental Quality
Low Emitting Materials Adhesives and Sealants Paints and Coatings Composite Wood Indoor Chemical and Pollutant Source Control Controllability of Systems Perimeter Spaces Non-Perimeter Spaces

23 Indoor Environmental Quality
Thermal Comfort Compliance with ASHRAE 55 Permanent Monitoring System Daylight and Views Daylighting in 75% of spaces Views for 90% of spaces

24 Example of Daylighting CSEP/PT/NODE37.html

25 Federal Government LEED Applications
General Services Administration (GSA) US Air Force US Army Corps of Engineers Department of State Department of Energy (DOE) Environmental Protection Agency (EPA) US Navy

26 State Government LEED Applications
California Pennsylvania – all new construction Oregon – tax credit New York Maryland – all buildings over 500,000 ft2 New Jersey – schools, and voluntary applications Arizona Missouri Wisconsin

27 Local Government LEED Applications
Austin, Texas Boulder, Colorado Los Angeles, California San Diego, California San Mateo, California Arlington, Virginia Cook County, Illinois Portland, Oregon San Jose, California Seattle, Washington

28 Incentives Sell energy back to the utility company
Tax breaks on new technologies Rebates, grants and loans

29 Sources Questions? Ray Yunk, Professor of Architectural Engineering
Dustin Schafer, Instructor of Architectural Engineering Questions?
