MI Homebuilders Training - Background

Goal of integrating the following subjects for Michigan Homebuilders:

  • Michigan Uniform Energy Code
  • ENERGY STAR homes & products
  • Federal tax credits for new home construction
  • Building America best practices
mi homebuilders training background1
MI Homebuilders Training - Background

Project Objectives:

  • Emphasize the state residential energy code in relation to other building standards
  • Increase # of builders building ENERGY STAR homes & using ENERGY STAR products
  • Increase # of homes built to the federal tax credits standard
  • Increase use of Building America best practices

Streamlined Project Objectives:

  • De-mystify the various construction standards (state code, ENERGY STAR, LEED for Homes etc.)
  • Demonstrate that energy efficient homes can be constructed in a cost-effective manner beneficial to builders and homeowners

MI Homebuilders Training - Background

Methodology:

  • Workshop format: 6 half-day Michigan sessions
  • Presentation showing 3 different home styles achieving: 1) state energy code compliance, 2) ENERGY STAR certification & 3) federal tax credit qualification

Methodology:

  • Presentation also included Building America best practices
  • ENERGY STAR products were emphasized throughout
  • Michigan focus with all construction examples

  • Building America partner Venture, Inc.
  • Home Energy Raters (workshop presenters)
  • Homebuilders Association
  • Professional Program Evaluator
mi homebuilders training results
MI Homebuilders Training: Results
  • 7 sessions completed
  • Geographic spread: Detroit area (2 sessions), Ann Arbor (2 sessions), Lansing, Grand Rapids, Marquette
  • 167 participants
  • Pre-surveys completed before the sessions (assess current building practices & knowledge)
mi homebuilders training results1
MI Homebuilders Training: Results
  • Post-surveys completed after the session (gather info. on participant reactions to the workshops)
  • Home Energy Raters provided practical info. to building professionals

MI Homebuilders Training: Results

Evaluation included:

  • Assessment of the operation - delivery of the program (review of project materials – interviews with project managers and staff)
  • Estimations of potential energy savings as a result of the project (qualitative methods)
mi homebuilders training results3
MI Homebuilders Training: Results

Evaluation:

  • Program was well administered
  • Deliverables within budget
  • Despite concentrated delivery time, sessions were completed as planned
  • “Front-end” presentation preparation from SEO was helpful

MI Homebuilders Training: Results

Evaluation:

  • Workshop presenters exhibited good experience in the field
  • Project managers attended sessions to monitor content quality

MI Homebuilders Training: Results

Attendee breakdown:

  • 113 – direct housing construction ties
  • 54 – related professionals (gov., nonprofit, utilities etc.)
mi homebuilders training results6
MI Homebuilders Training: Results

Pre-survey results:

  • Previously built an ENERGY STAR home: 26% (8% built more than 1)
  • Had a HERS rating on their home: 30% (8% had more than 1)
  • Always or usually offer extra EE options: 62%
mi homebuilders training results7
MI Homebuilders Training: Results

Pre-survey results:

  • Are very familiar with the Michigan energy code: 25%
  • Are somewhat familiar with the Michigan energy code: 50%
  • Know the requirements of the federal tax credit for new homes: 23%
  • Applied for a federal tax credit: 19%

MI Homebuilders Training: Results

Pre-survey results:

  • Relatively low pre-existing level of knowledge & experience w/ advanced EE construction (suggesting even lower levels of knowledge from other builders)

MI Homebuilders Training: Results

Post-survey results:

  • Positive assessment of workshops from attendees
  • Purpose of training was clear: 93%
  • Met or exceeded expectations: 96%
  • Very useful or fairly useful: 97%
  • Learned new building science info: 86%

MI Homebuilders Training: Results

Post-survey results:

  • Most important finding: 95% said they would apply info learned to their own building practices

Energy Savings Impact:

  • Training programs present challenges for estimating energy savings impact
  • Hypothetical scenario: ½ of the attendees responsible for 3 additional ENERGY STAR rated homes following the training (conservative assumption)
mi homebuilders training results12
MI Homebuilders Training: Results

Energy Savings Impact:

  • Energy savings per home: estimates provided from HERS presenters with software modeling
  • Average estimated annual energy cost savings per medium sized home built to ENERGY STAR standards: $700
  • 83 attendees X 3 homes X $700 = $174,300 annual savings
mi homebuilders training results13
MI Homebuilders Training: Results

Energy Savings Impact:

  • Conservative estimation suggests 1 year of resulting energy savings is more than twice the project budget cost ($74,000)
  • Translates to about ½ year payback period for the project
  • Assuming a 40 yr. lifetime of a new home, lifetime energy savings are approx. $7 million at current energy prices – exceeding project costs by almost 100 fold
mi homebuilders training results14
MI Homebuilders Training: Results

Energy Savings Impact:

  • This all assumes no “spill-over” savings potentially resulting from the training beyond the 3 new homes per 83 attendees
mi homebuilders training conclusions
MI Homebuilders Training: Conclusions
  • In the absence of actual impact evaluation results, a conservative projection of energy savings far exceeds the project costs
  • HERS providers/workshop presenters provided valuable insights to evaluator regarding:
  • perceived marketplace obstacles
  • effective EE features to promote to customers, and
  • suggestions of how to increase the # of ENERGY STAR rated new homes
mi homebuilders training recommendations
MI Homebuilders Training: Recommendations
  • The evaluation suggested this type of training approach should be reproduced on a larger statewide scale reaching more builders
  • Couple the training effort with utility sponsored financial incentives to builders and/or home buyers
  • Concentrate future training sessions during builder’s off-season
  • Diversify future training to accommodate builders new to the EE concept and seasoned EE experienced builders
  • Consider having the program pay for one home energy rating for each builder attending a workshop
mi homebuilders training conclusions1
MI Homebuilders Training: Conclusions
  • Project was well-designed & delivered w/ responsible administration & good quality control
  • Existing level of EE knowledge of builders attending was fairly low – suggesting builders who did NOT attend would feature a lower level of EE knowledge
  • Attendees rated the training very high
  • Using conservative assumptions, the project will likely result in total energy savings far in excess of the costs of the project
