Title: Green Building


1
Green Building
  • The future of home building is green building
  • Charlie Ruma, Immediate-past President of NAHB

2
Definition
  • green building is the resource-efficient
  • 1. design
  • 2. construction, and
  • 3. operation
  • of buildings by employing environmentally
    sensible
  • 1. construction practices
  • 2. systems, and
  • 3. materials

3
Facts
  • recent phenomenon (1991)
  • about a 2 dozen green building programs in
    existence
  • municipal
  • voluntary (Austin, TX)
  • mandatory (Boulder, CO Frisco, TX)
  • HBA
  • voluntary (Denver, CO Atlanta, GA)
  • more to come

4
Components
  • main areas addressed by green building programs
  • energy and resource efficiency
  • water conservation
  • health and environmental quality
  • materials and waste management
  • site design and protection

5
Energy Standards
  • reduces energy consumption
  • passive solar design
  • light-colored roofing
  • energy-efficient appliances
  • low emissivity windows

21
Why Arent There MoreGreen Buildings?
  • decentralized building industry
  • information barriers
  • split incentives
  • transaction costs
  • financial barriers
  • energy costs

22
1. Decentralized Building Industry
  • 5.5 million people in construction industry
  • from concept to occupancy, constructing a
    building requires
  • developers, architects, landscape architects,
    site planners, engineers, contractors,
    craftworkers, interior decorators, realtors,
    lenders
  • vast number of companies and individuals require
    education and training in the concepts and
    techniques of green building before it will
    become the norm

23
2. Information Barriers
  • builders and consumers often lack reliable
    information about renewable or energy-efficient
    technologies
  • consumers lack information about energy
    consumption of appliances
  • builders lack information on latest techniques
    and materials used in resource and
    energy-efficient building
  • government officials lack information about the
    benefits of green building and how those
    principles can be applied in their communities

24
3. Split Incentives
  • developers, builders, landlords, and others who
    choose the structural components and equipment in
    a building often are not the ones paying the
    operating costs
  • minimize initial cost outlay to minimize the
    overall cost of the building

25
4. Transaction Costs
  • numerous transaction costs combine to emphasize
    speed in the building process
  • builders go with what they know
  • often less expensive, less efficient products
  • dont have time to try out new products
  • dont have time to learn new techniques

26
5. Financial Barriers
  • many builders and homeowners only look at initial
    cost
  • technologies that increase the energy efficiency
    of buildings and substitute renewable energy for
    fossil fuels usually raise the initial cost of a
    building.
  • homeowners lack the capital
  • consumers dont take advantage of the financial
    incentives that exist to help them
  • energy efficient mortgages (EEMs)

27
6. Energy Costs
  • often small cost of the total budget of building
    a new home
  • lack of interest on part of consumers leads to
    lack of action on part of builders

28
Possible Solutions
  • overarching problems
  • education
  • building industry
  • homeowners
  • government officials
  • financial
  • incentives

29
Possible Solutions (cont.)
  • building industry
  • continuing education and training for the
    building industry
  • public (HUD, DOE, EPA)
  • private (NAHB and local HBA)
  • university-level
  • expand local programs
  • EPA Energy Star
  • Green Advantage (Florida Energy Extension
    Service)
  • UF Center for Construction and Environment
  • Florida Green Building Coalition (FGBC)

30
Possible Solutions (cont.)
  • homeowners
  • education on the benefits of buying green
  • local government
  • GRU
  • Local HBA
  • environmental groups
  • Green Advantage (FEES)
  • EPA Energy Star program

31
Possible Solutions (cont.)
  • local government
  • strengthen building codes
  • government sets building codes and regulations
    to
  • protect against shoddy craftsmanship
  • promote public health and safety
  • ensure compatible land uses
  • protect community values
  • why not set codes and regulation to require more
    greener construction practices
  • Austin, TX
  • Boulder, CO
  • Frisco, TX
  • require municipal building to be green
  • marketing and technical advice for builders

32
Possible Solutions (cont.)
  • local government
  • builder incentives
  • fast-track permitting
  • reduced builder fees
  • homeowner incentives
  • GRU
  • property tax exemption
  • energy efficient mortgages (EEMs)

33
Efforts to Develop Green Building Codes and
Standards

  • DOE Home Energy Rating Systems (HERS) guidelines
  • EPA Energy Star
  • qualifies homes for EEMs
  • Florida Green Building Coalition
  • third draft of standards

34
Home Energy Rating Systems (HERS)
  • developed by DOE in1992
  • 1993 17 states had HERS
  • today 49 states have HERS
  • rates the energy-efficiency of new and existing
    homes
  • rates homes between 0-100
  • qualifies homes for energy efficient mortgages
    (EEMs)
  • 80 EEM
  • 86 Energy Star

35
Home Energy Rating Systems (HERS) (cont.)
  • home energy rater inspects the home and and
    measures its energy characteristics
  • insulation levels
  • window efficiency
  • wall-to-window ratios
  • heating and cooling system efficiency
  • solar orientation of the home
  • efficiency of the water heating system
  • diagnostic testing
  • blower door test (air leakage)
  • duct leakage test

36
Energy Efficient Mortgages
  • mortgage for which either
  • underwriting guidelines have been relaxed
    specifically for energy-efficient features, or
  • financial incentives for energy-efficiency
  • new and existing homes
  • HERS score of 80 or above (1993 MEC)
  • more than 2.5 billion in federally-supported
    EEMs have been issued to date
  • Fannie Mae
  • Freddie Mac
  • HUD-FHA
  • VA
