Comprehensive Usage Reduction Program Evaluation Affordable Comfort 2007 Jacqueline Berger
Evaluation Objectives • Determine the cost-effectiveness of WRAP • Develop standard questions so PPL can measure the same criteria in future evaluations • Comply with the PUC Order 2
Evaluation Questions • What are the goals and how are they met? • What are the admin costs? How can they be lowered? • How effective is program recruitment? • Is the audit mechanism effective? • Is the list of program measures comprehensive? 3
Evaluation Questions • Is the education process cost-efficient and effective? • What is the level of post-inspection and is it appropriate? • Does PPL coordinate WRAP with other weatherization programs? • What are the energy savings? 4
Evaluation Questions • What is the cost-effectiveness of the various agencies? • Does PPL provide adequate support and training for contractors? 5
Evaluation Design • Background Research • Review of Specifications and Procedures • Contractor Survey • Baseload Observations • Full Cost Observations and Inspections 6
Evaluation Design • Customer Survey • Usage Impacts • Payment Impacts 7
Background Research • Goal – develop a complete understanding of the WRAP procedures and implementation. • Activities • Interview WRAP managers and staff • Review program documentation • Review program statistics • Outputs • Understanding for research foundation • Documentation 8
Background Research • Key Findings • PPL has five managers who oversee WRAP and other low-income programs in their geographical area. • Advantage: ability to focus on needs in a particular geographic area • Disadvantage: many responsibilities – difficult to oversee work of contractors • PPL spends much effort to come within 4% of expenditure goal (based on PUC requirement). 9
Background Research • Key Findings • Affordability customers are prioritized. • Otherwise, jobs sent to contractors on a first come first served basis. • Program coordination barriers • Long waiting lists for WAP • Long waiting lists & requirements for gas programs • Customers who use gas and electric may not have high enough usage to qualify for either program 10
Background Research • Recommendations • Prioritize customers based on usage. • Track program coordination and provide incentives for contractors to coordinate services with other programs. • Continue to introduce technological improvements, such as the web-based measure reporting form. 11
Review of Specifications and Procedures • Goal – Determine potential effectiveness of measure selection, measure installation, and energy education • Activities – Assess procedures and forms: • Education specifications • Education forms • Written technical procedures and manuals • Measure installation rates 12
Review of Specifications and Procedures • Outputs • Recommendations for modifications to: • Education procedures • Education forms • Measure selection guidelines • Procedures manual 13
Review of Specifications and Procedures • Education Findings • All participants receive at least one on-site education visit • Follow-up education is provided at the time of the inspection or by phone • Remedial education provided to customers whose usage increases by at least 10% six months after service delivery 14
Review of Specifications and Procedures • Education Recommendations • Education should be provided at the time of the audit. The homeowner should be present. • Customer profile should collect information on potentially large opportunities for saving – use of dehumidifiers, use of second refrigerators, lights/appliances left on at all times. • Action form should prioritize actions by the potential for energy saving in the individual home. Should list top 3-5 actions with estimated $ savings. 15
Review of Specifications and Procedures • Technical Findings and Recommendations* • Review cost-effectiveness calculations in audit decision trees to reflect current estimates of costs and savings. • Refrigerators • CFLs • Water heater wraps and pipe insulation may be more cost effective than water heater replacement. *Blasnik & Associates. 16
Review of Specifications and Procedures • Technical Findings and Recommendations • Duct sealing in basements should be focused on safety and comfort. • Blower door guided air sealing: investigate why only done in 60% of full cost jobs. • WRAP standards and field guide: more concise program field guide with separate specifications for specific areas may be useful. 17
Contractor Survey • Goal - Assess contractor compliance with program procedures, and assess problems in program administration. • Activities • Develop contractor survey instrument • Determine survey sample • Send survey to contractors • Review completed surveys and contact respondents for additional information/clarifications 18
Contractor Survey • Outputs - Understanding of: • Contractor background and experience • Support and training provided to contractors • Usefulness of program forms • Program implementation procedures • Joint service delivery with WAP • Health and safety problems found in homes • Contractors’ quality control • Inspection issues 19
Contractor Survey • Outputs - Recommendations related to: • Program procedures • Contractor training and support • Inspection procedures 20
Contractor Survey • Recommendations • Revisit audit forms and determine whether they can be consolidated. • Require home walkthrough on all jobs. • Formalize a process to respond to action sheets. 31
Baseload Observations • Goals - Understand how well contractors address opportunities for baseload usage reduction and whether education is effectively provided. • Activities • Sample design and selection • Observation protocols • Conduct observations • Review findings and synthesis 32
Baseload Observations • Outputs - Recommendations for: • Additional contractor training • Additional quality control 33
Baseload Observations • Recommendations • Review WRAP requirements and expectations with contractors. • Provide education to contractors on the importance of 2-for-1 swaps in refrigerator replacement. • Conduct observation of baseload service delivery. 42
Full Cost Observationsand Inspections • Goals - To understand: • How well contractors address opportunities for electric usage reduction • Whether correct measures were selected • Extent to which energy education is provided. • Activities • Sample design and selection • Observation protocols • Review WRAP technical protocols • Conduction observations • Review findings and synthesis 43
Full Cost Observationsand Inspections • Outputs – Recommendations for: • Procedures • Training 44
Full Cost Observationsand Inspections • Comments • They were on the right track. They were not afraid of working hard. • What he did was correct, but he should have done more air sealing. • He looked at all the right things and asked the homeowner to clarify things that were not obvious. 50
