HPC manages several research and data standards projects that seek to strengthen the residential energy efficiency industry and make it profitable for contractors and other businesses to perform energy efficiency upgrades. We do this by partnering with industry, government, and other nonprofit organizations to identify and address market barriers to industry growth, including:
- High internal and transactional costs associated with efficiency program implementation and evaluation;
- Limited homeowner access to energy usage and consumption data; and
- Lack of empirical data on building and measure performance
Below is a brief overview of our project areas and how they address these barriers, with links to more information.
HPC is driving data standardization in the industry by leading the development and maintenance of several residential energy efficiency data standards including the HPXML Data Dictionary and the HPXML Transfer Standard. These open data standards were created to facilitate the communication and exchange of information among stakeholders in the residential energy efficiency industry, and are helping businesses and efficiency programs operate more efficiently, increase productivity, and access new markets.
Valuing Home Energy Efficiency
As consumer interest in energy efficiency as a valued feature of residential properties grows, several states have responded by making information about energy efficiency readily available for property listings. HPC works with partners of DOE's Home Energy Information Accelerator to make efficiency improvements visible in the real estate transaction through the creation of standardized datasets and transfer protocols. When information about energy efficiency improvements is visible to home buyers and others involved in the home sale transaction, these improvements are more likely to be fairly valued at the time an existing home is sold.
Smart Home Performance
Smart home technologies, like Home Energy Management Systems, are becoming increasingly valuable tools to help customers and utilities manage energy demand and identify high energy users. HPC works with the Northeast Energy Efficiency Partnerships, energy efficiency programs, and product manufacturers to integrate smart home technologies into existing and new programs.
Reforming Cost-Effectiveness Testing
Cost-effectiveness tests are important tools that decision-makers use to determine which efficiency resources are in the public interest and what level of investment is appropriate. However, programs typically rely on tests that fail to consider the benefits of residential energy efficiency along with its costs. The National Efficiency Screening Project was created to reform energy efficiency screening practices by providing decision-makers with the principles, concepts, and techniques for sound, unbiased evaluation of energy efficiency and other demand side resources.
