Creating an energy-efficient home is a worthwhile goal. It is cooler in the summer, warmer in the winter, costs the homeowner less money to keep it that way and helps the environment. What’s not to like? Well, the difficulty of finding financing for upgrades, choosing the right equipment or systems and hiring contractors who are experienced in properly installing high-performance systems, to name just a few challenges.
To help homeowners overcome these barriers to successful energy-efficiency upgrades, the Department of Energy launched Home Performance with ENERGY STAR (HPwES) in 2011. The program connects homeowners with program sponsors and contractors who can help them improve their home comfort, indoor air quality and safety, while lowering utility bills.
How it works
HPwES takes the “whole house” approach to energy improvements that helps make the most of the homeowner’s investment. Rather than focusing on a single problem, participating contractors look at how improvements throughout the house can work together to get the best results.
To find participating contractors, homeowners go through HPwES-sponsored local programs. The contractors, who are trained to understand how homes operate, identify health and safety issues and provide the homeowner with personalized recommendations for increasing the house’s energy efficiency.
HPwES sponsors perform quality assurance checks on their contractors to ensure that the improvements are done right. In states where incentives are available, sponsors may also help homeowners apply for rebates.
Supporting retrofit programs
Becoming a Home Performance with ENERGY STAR sponsor is good for utilities as well as homeowners. Starting a residential efficiency improvement program from scratch is difficult, even for large utilities. Sponsors have access to a variety of resources they can use to implement and grow their programs and reach their own local energy savings goals. Program support includes account management services, marketing material, partnership and collaboration opportunities and resources from the Better Buildings Residential Solutions Center.
Because sponsorship is not limited to one type of organization, utilities have the opportunity to partner with municipalities, state energy programs and financial institutions. Collaborating with other agencies can make programs more effective, multiplying the benefits of efficiency upgrades across communities.
Helping sponsors to develop their own programs and connecting them to contractor pools is not the only way HPwES works to break down the siloes that stand in the way of a more efficient marketplace. Last year, the program introduced the HPXML Implementation Guide to help program administrators and software developers integrate HPXML into their operations and products.
Developed by Building Performance Institute, HPXML is a set of common definitions for the attributes of home systems. It also includes computing language to facilitate the quick and easy transfer of home-related data between different market actors. Collecting and sharing this data across the industry is critical to supporting, measuring and verifying energy performance. The DOE expects the use of HPXML to build stronger relationships within the industry, increase consumer trust in energy-efficiency improvements and enhance the ability to evaluate programs.
Most program managers agree that measurement and evaluation is one of the big challenges of administration, so the HPXML guide could be a valuable resource for utilities. Visitors can learn more about the value the HPXML guide can bring to businesses, along with implementation methods, from a recorded webinar on the website.
