CRP Home Comfort Program Overview
PGW’s LIURP, re-designed and launched in 2011
Program Goals:
• Primary – Provide cost-effective energy savings to
customers participating in PGW’s CRP
• Secondary – Reduce overall long-term cost of the CRP
as paid by all firm customers
9,092 customer installations & $8.1mm in present value net
benefits from inception to February 2015
Greatest Challenge: characteristics of PGW’s low-income
customers’ homes

Program Design
Highest usage customers on CRP assigned to program
3 program contractors (CSP) who are evaluated based on:
• Total energy savings
• Cost-effectiveness
• QA and other metrics
CSPs perform energy audits and create work scopes for
cost-effective gas savings using the PGW Program Tool
CSPs complete the installations, paid for by PGW

Auditor identified health and safety issues preventing
comprehensive weatherization.
• Seize any opportunities for savings at audit
• Set-back thermostat
• Water heater pipe wrap & low-flow devices
• CO detector
• Customer education

Health and Safety Challenges
Health & Safety issues prevent
comprehensive weatherization in at
least 37% of cases
Inefficient homes are often a
symptom of more severe structural
and mechanical problems
14
Health and Safety Partnerships
PGW coordinates with local agencies to address health and
safety improvements required for weatherization
Customers that can’t be helped by these programs are
provided a list of resources that may be of help
15
Quality Assurance & Mentoring
Program inspector focuses on training and
mentoring to capture missed opportunities
Better definitions and shared language
between contractors, customers and others
Deeper savings and cost-effectiveness
offer more flexibility for non-energy
measures
