Efficient Homes

Building higher performing and more comfortable homes

NEEA and its utility partners accelerate market adoption of energy-efficient homes by partnering with the EPA to offer builders the tools they need to verify and certify energy-efficient homes, and by providing regional marketing, recruitment and training support in the Northwest.

Northwest ENERGY STAR Homes offers information, tools and resources on the energy-efficient features and increased comfort of homes that are at least 15 percent more efficient than existing state building codes. NEEA is now leveraging its work through Northwest ENERGY STAR Homes and relationships with strong market partners and utility support, to explore the next phase in new construction through the Next Step Home pilot.

This pilot will be used to identify the most cost-effective methods for achieving the greatest amount of energy savings, while paving a pathway for future code adoption.

 

  • Northwest Ductless Heat Pump Initiative- Market Progress Evaluation Report #3
    This is the third Market Progress Evaluation Report (MPER) of the Northwest Ductless Heat Pump (DHP) initiative. The evaluation shows that general population awareness of DHPs has increased from 34% to 48% in 2012. Utilities that participated in the initiative in 2012 installed nearly 5,300 DHPs, primarily in Oregon and Washington. In comparison, utilities installed about 4,800 DHP systems in 2011, resulting in a nine percent increase for 2012. Households that have installed DHPs have high satisfaction with nearly all households (94%) using their new DHPs for primary heating. Installers, manufacturers and distributors predict continued DHP market growth with one in four general population households showing interest in installing DHPs. The primary barriers impeding continued market growth are installation costs, public awareness and understanding of DHP technology and aesthetic concerns.

  • Oregon Residential Energy Code Compliance
    This report describes the compliance of residential new construction in the state of Oregon with the revised state residential code: Chapter 11 of the 2011 Oregon Residential Specialty Code (ORSC). The study team assessed compliance using two different approaches: 1) Pacific Northwest National Laboratory (PNNL) checklist method: This approach analyzed how well the studied homes complied with each of the sixty-one process and efficiency requirements found in the code; 2) Significant item method: This approach analyzed compliance based only on measures that were considered to have the most significant impact on energy use. Compliance rates for the two methods were found to be 91% and 96% for the checklist and significant items methods respectively. In addition, the study team assessed the energy impacts of code compliance by using a building simulation model to determine the relative energy use of each home as-built compared to the energy use of a reference home built to meet the prescriptive code.

  • Final Summary Report for the Ductless Heat Pump Impact and Process Evaluation
    The Ductless Heat Pump (DHP) Pilot was a large-scale regional effort intended to validate a provisional savings estimate established by the Regional Technical Forum (RTF) while demonstrating market acceptance of units in existing zonal, electrically-heated residential homes. This report represents a summary of the five research areas undertaken as part of the DHP Pilot that occurred between 2009 and 2013. These include market progress evaluation, laboratory testing, field monitoring, billing analysis, and cost analysis/non-energy benefits. Key findings reiterated in the summary report include a high level of customer satisfaction with DHP units (92%), high coefficients of performance across a range of temperature conditions, and an identification of ancillary benefits to occupants (including the reduction of supplemental fuel and increased temperatures in adjacent living space). The overall program implications of this research suggest that this is an important and transformational technology which can appreciably offset electric space heating requirements in simple electric resistance systems without disrupting the existing heating system or underlying home structure.
