          grams/neighborhoodspg/pdf/nsp2_nofa.pdf
               NSP2 Funding
• $1.93 billion available to carry out neighborhood
  stabilization programs (min grant is $5million
  and impacting 100+ homes)
  – deadline for submission of these applications is July
    17th, 2009
• $50 million available to provide technical
  assistance to local communities receiving NSP1
  or any entity receiving NSP2 funding to carry out
  neighborhood stabilization

    Eligible Applicants for NSP2
              Funding
• You MUST be a:
  – state government, OR
  – a unit of general local government, OR

    NSP2 Competitive Scoring
• Six rating factors that all applicants are
  competing for points under
• 150 available points in the competitive
  process
• 10 points are awarded for sustainable
  construction/development components
Green building standards for NSP2
• 3 points for applications that comply with the
  required NSP2 rehabilitation standards AND
  demonstrate that:
  – New construction and gut rehabilitation activities will
    exceed the ENERGY STAR for New Homes standard
    OR
  – New construction or gut rehabilitation required to
    achieve an established performance standard such
    as Green Communities or equivalent AND
  – Moderate rehabilitation or energy retrofits will
    purchase only ENERGY STAR products and
    appliances
    What is ENERGY STAR?
• National program to recognize homes that
  are 15% more efficient than homes built to
  2004 IECC

    ENERGY STAR Process for
         Qualification
1. Find a Rater
2. Register as an ENERGY STAR Partner
3. Preconstruction Meeting
  3.5 Preliminary HERS Rating
4. Thermal Bypass Inspection
5. Make Improvements Based on Thermal
   Bypass Inspection
6. Final Inspection and Verification
          1. Find a Rater

                /directory.aspx
               1. Find a Rater
• What to ask the rater:
  – Experience with ENERGY STAR in your area
     • http://www.energystar.gov/index.cfm?fuseaction=new_home
       s_partners.showHomesSearch
        – Choose “Home Energy Raters”
  – Experience with other green building programs
  – Services offered and turn around time
  – Pricing

      What is a HERS Rating?
Components of HERS Rating
1. Assessment of Building Components
2. Diagnostic Testing
3. Software Modeling
4. Reporting
   Index = PEfraction x 100 x [Rated Home’s Htg + Clg + DHW + L.A.]
                               [Ref. Home’s Htg + Clg + DHW + L.A.]

           where PEfraction is ratio of renewables to purchased energy &
                    L.A. is lights and major appliances
