Preliminary Performance Report
Proposed Thermal Envelope
▪ Unvented and air sealed attic with Holcim/Enverge open-cell spray-foam insulation. (R-20)
▪ Existing windows and doors replaced with Jeld-Wen high-efficient, low-e glass to limit solar heat gain and optimize air tightness.
▪ Exterior block walls insulated with Fi-Foil M-Shield reflective wall insulation.
▪ Light colored exterior to assist in reflecting the sun.
▪ Aeroseal’s AeroBarrier for air sealing the home’s thermal envelope efficiently and effectively
▪ Air infiltration performance to be tested on-site and projected at less than 7 ACH(50).
▪ A proposed 100% improvement over the pre-remodeled tested envelope leakage of 14.1 ACH50.
Proposed HVAC
▪ Highly Efficient AC system by Midea.
▪ FanTech Exhaust Fans throughout the home, including the crawl space.
Proposed Water Heaters
▪ Rinnai ENERGY STAR®-rated tankless water heaters.
Electrical
▪ 100% energy-efficient interior and decorative LED lighting by Progress Lighting/Kichler Lighting (Coleto Brands)
▪ GE ENERGY STAR®-rated appliances.
▪ ENERGY STAR®-rated variable speed pool pumps.
Energy Efficiency and Innovation
As one of the NAHB’s official show homes, The New American Remodel (TNAR) 2026 is a symbol of energy efficiency and innovation. Its energy-efficient features can be used in homes in a hot, humid climate at any price point with similar energy savings. The home exhibits innovative products from manufacturers all over the world. TNAR 2026 is designed to exceed the requirements for certification to the Gold level of the National Green Building Standard™.
TWOTRAILS™ worked closely with Phil Kean Design Group to ensure energy efficiency and innovation in TNAR 2026. The pre-remodel home has a projected HERS Index of 91, and with the proposed upgrades and improvements, the projected HERS Index after the remodel is a 49!
Water Efficiency Features
In addition to energy savings, this home is designed to achieve an estimated 50% reduction from baseline in water use. This remarkable water use reduction is made possible using low-flow water fixtures, natural drought tolerant landscaping, and a high-efficient irrigation system. Water saving features include:
▪ Kohler low-flow, EPA WaterSense certified 1.2 GPM lavatory faucets and an average of 1.28 GPF toilets provides indoor water use reduction.
▪ High-efficient micro spray, driplines and irrigation controllers contributed to the outdoor water use reduction.
Indoor Environmental Quality Features
Indoor Environmental Quality encompasses the conditions inside a home, and their effects on residents. The New American Remodel 2026 incorporates innovative strategies, creating an indoor environmental quality that enhance the lives of homeowners, protects occupants’ health, and improves quality of life. Indoor Environmental Quality strategies include:
▪ Sherwin Williams Low-VOC paints and finishes and low-VOC interior adhesives and sealants.
▪ MERV 13 space conditioning AC air filters.
▪ HVAC ducts are sealed during construction to prevent pollutants from construction activities from entering the system.
Systems Engineering Approach
The systems-engineering approach unites segments of the building industry that have previously worked independently of one another. The concept is simple: systems-engineering can make America’s homes cost effective to build or retrofit and energy efficient to live in. Energy consumption of new houses can be reduced by as much as 40% with little or no impact on the cost of construction.
To reach this goal, the Phil Kean team is working with their building partners to produce a home that incorporates energy and material saving strategies from design through construction. First, the team analyzed and selected cost-effective strategies for improving home performance. Next, the team evaluated design, business, and construction practices within individual partnerships to identify cost savings. Cost savings could then be reinvested to improve energy performance and product quality.
Proving the efficiency of the system-engineering approach to construction, the pre-remodel home has a projected HERS Index of 91, and with the proposed upgrades and improvements, the projected HERS Index after the remodel is a 49!
