ENERGY STAR Certified Homes
Definition:
ENERGY STAR Certified New Homes are residences that meet the stringent energy efficiency guidelines established by the U.S. Environmental Protection Agency (EPA). These homes are independently verified to be at least 10% more energy-efficient than homes built to code, with an average improvement of 20%. They feature a comprehensive package of energy-efficient systems and features designed to enhance performance and comfort.
Short Description:
ENERGY STAR Certified New Homes are designed and constructed to surpass standard building codes in energy efficiency, offering homeowners improved comfort, quality, and reduced utility costs.
The ENERGY STAR Certified Home program is for newly constructed homes (although it may be available for existing homes when doing a gut rehab). The program evolves as building practices improve. As of February of 2025, the program is in Version 3. Different versions depend upon different state energy code requirements. As of February of 2025, the most advanced version is 3.5.
Why It’s Important:
Choosing an ENERGY STAR Certified New Home delivers:
•Enhanced Comfort: Advanced construction techniques and materials maintain consistent indoor temperatures, reducing drafts and improving air quality.
•Lower Utility Costs: Energy-efficient systems and appliances decrease energy consumption, leading to significant savings on heating, cooling, and water heating expenses.
•Environmental Responsibility: Reduced energy usage lessens greenhouse gas emissions, contributing to environmental protection.
•Quality Assurance: Third-party verification guarantees that the home meets or exceeds ENERGY STAR standards, providing peace of mind regarding the home’s performance.
Other Things to Consider:
•When the home earned the label: Not all ENERGY STAR Certified Homes are the same. A home built to Version 2 standards is different than a home built to Version 3 standards.
•The label is binary: ENERGY STAR Certified Homes must meet a threshold to earn the label. One home may barely pass that threshold, while another home may have far exceeded that threshold. Looking into the HERS rating or other characteristics of the home is also informative.
•Comprehensive Features: ENERGY STAR Certified New Homes include:
•Complete Thermal Enclosure System: Effective insulation and air sealing to enhance comfort and reduce energy loss.
•High-Efficiency Heating, Ventilation, and Air Conditioning (HVAC) System: Properly installed and sized systems to improve performance and indoor air quality.
•Water Management System: Features that protect roofs, walls, and foundations from moisture damage.
•Energy-Efficient Lighting and Appliances: Products that use less energy without compromising performance.
•Third-Party Verification: Each home undergoes independent inspections, testing, and verification by certified professionals to ensure compliance with ENERGY STAR requirements.
•Market Advantage: ENERGY STAR certification can enhance a home’s resale value and appeal, as energy efficiency becomes an increasingly desirable feature among buyers.
