Sam Rashkin - Energy Star

  1. 1. SOCALGREEN CONFERENCE SYMPOSIUM SEPTEMBER 2, 2010 ENERGY STAR Qualified Homes Version 3: Assured Performance with Every Labeled Home Is Good Business
  2. 2. ENERGY STAR QUALIFIED HOMES VERSION 3 OUTLINE • The Product: Dissecting the Home Purchase • The Context: Energy Star in a ‘Green’ World • The Industry: The New Normal • The Business Case: Addressing New Normal • The Metrics: Why Energy Star = Good Policy
  3. 3. THE PRODUCT DISSECTING THE HOME PURCHASE • Home = Lifestyle Liability • Building Science = Investment + Performance • Renewable Power = Investment + BOH
  4. 4. THE CONTEXT: ENERGY STAR FOR HOMES vs. GREEN ENERGY STAR Green Programs for Homes for Homes Voluntary Recognizes Builders Label Web Site, Marketing, Awards
  5. 5. THE CONTEXT: ENERGY STAR FOR HOMES vs. GREEN ENERGY STAR Green Programs for Homes for Homes Voluntary Recognizes Builders Label Web Site, Marketing, Awards Defines Efficient Offers Flexibility Predominantly Mandatory Points Binary Multiple Tiers
  6. 6. THE CONTEXT: ‘GREEN’ BEGINS WITH ‘BLUE’ Resource Efficiency •Water Indoor •Materials Environment •Waste Energy •Source Control •Recycling •Ventilation •Land Efficiency •Filtration •Renewables •Air Flow •Thermal Flow •Moisture Flow •Equipment
