Q&A: Energy efficiency tips




Vermont Gas Systems’ strong belief in energy efficiency is a key component of the company’s operating principles.  As part of its commitment to the efficient use of energy, Vermont Gas has offered  “Demand-Side Management” (DSM) programs to both residential and commercial customers since 1992. 


Whether you're building a new home, trying to save energy in an existing home, or installing a new furnace, boiler, or hot water heater, Vermont Gas has efficiency experts on staff and three distinct residential energy efficiency programs to help you make the best decisions for your specific situation.

Retrofit Program
The Retrofit Program is designed to help customers with larger than average gas usage find ways to improve the efficiency of their homes. Vermont Gas customers whose home has used at least 0.5 Ccf per square foot of natural gas over the past year are eligible. For example,  a 2,000 square foot home that consumes more than 1,000 Ccf per year qualifyfor this program, as are multi-family buildings where the total building usage is at least 0.5 Ccf per square foot of natural gas. If you don't own your home, Vermont Gas must receive direct authorization from the landlord to qualify for an energy audit. Vermont Gas provides financial incentives to encourage qualifying customers to install cost effective energy conservation measures.

A Free energy audit is performed on each participating building to identify potential energy saving measures. The auditor looks at existing insulation levels, evaluates building air-tightness, and tests the heating system efficiency. Potential improvements are modeled using a computer audit tool to determine the cost effectiveness of improvements and to estimate the savings that may result. Building owners are then provided with a written report summarizing the audit results and detailing the incentives available. The report also includes a list of contractors and the specifications needed for contractor bidding. Customers have the choice of obtaining competitive bids, or having VGS assign a pre-screened contractor to do the work.

This program has been designed to encourage the installation of significant building improvements that will have a long-term impact on the energy efficiency of structures. Typical measures may include blown-in cellulose insulation for walls and ceilings, and specific air sealing measures designed to make houses less drafty. In some cases, heating system and distribution improvements are also recommended.

Typically Vermont Gas will rebate 33 1/3% of the installed cost of the recommended measures and provide a reduced interest loan through a local Credit Union for the balance. Currently, customers are offered loans at 0% interest for up to 3 years, 2% interest for up to 5 years, or 4% interest for up to 10 years.

Low-income customers are referred to the Champlain Valley Weatherization Service (CVWS) for priority assistance. CVWS determines the customer's income status and eligibility, performs the energy audit, submits the recommended measures to VGS for screening, and coordinates the installation of the cost-effective energy saving measures. VGS shares the costs of these jobs with CVWS.
