BUILD Construction and Engineering Awards 2025 Leading Net Zero Window Systems Provider 2025 – USA & BUILD Client Service Excellence Award 2025 Client Service Excellence is delivering Net Positive energy performance in the first ever building to use WonderWindows in advanced 24” on-center lightweight wood frame new construction: regenerative sustainability built in. The 672sf home we built in Chico, California with Version 1.0 of our window-integrated building envelope has produced a million watt-hours more than it consumed since the end of February with only 2.8kw of rooftop solar and a 'small' 5 kwh battery. The home cost $172,000 in hard construction cost with land & soft costs tipping a $300,000 total", said GS Research LLC’s Founder & CEO Mark Isaacs. WonderWindow-integrated framing sets up right-sized seasonally shaded windows on the South and North with no windows on the East or West. Through most of the summer, the owner reports thermal comfort at home with NO air-conditioning turned on, assisted by the indoors cooling from the 50-gallon heat pump hot water heater. SEER 21 mini-splits provide zone-controlled yearround heating and cooling when needed. “I suppose we are the Leading Net Zero Window Systems Provider in the USA because of our fundamental understanding of buildings as integrated systems with composite, effective thermal resistance, plus solar gain controlled according to season, climate and orientation, said Isaacs. WonderWindows are multi-pane acrylic windows, developed in 2 issued patents plus a recent patent pending making Version 2.0 of the windows easier & quicker to assemble onsite or deliver to your door. A 22” x 48” fixed R7 window costs $290 for twice the thermal resistance of US Energy Star windows. However, the Wonder is in the Walls and Building Envelope as much as the Windows. The windows fit between 24” on-center 2x4 studs (1-1/2”x 3-1/2” actual). Walls and Windows work together as an integrated system, where Version 2.0 yields 8” of boratepest-and-fire-treated densepack cellulose insulation in an R30 wall built on a 2x4, 24” on-center frame ‘chassis’, with the patentpending solution dialing in R30-R45 walls and R45-60 ceilings according to climate zone location. Small homes, ADUs, and micro-homes designed with this 2’ modular wood framing have up to 63% fewer pieces of lumber in a wall. Fitting between the 2’ on-center studs, WonderWindows safely eliminate headers, jack and cripple studs. Framing factors, the percentage of opaque wall occupied by wood framing, drop from 22-25% of conventional 2x4, 16” on-center stud walls to 9% of the 2x4, 24” centered integrated walls, increasing the wall volume available for insulation. The fire-resistive cellulose insulation is contained inside and out by 4’x8’ fiber-cement panels with 1x3 fiber-cement trim that add to overall fire-resistance. Bio-based forest products yield fire-resistant cost-, material-, and energy-efficiencies with low-embodied energy, high recycled-content, & low carbon footprint. Ground-contact heavy timber creates a perimeter foundation with R30 insulated floors, eliminating concrete slab and/or floor framing, at LESS COST than conventional construction. A design for a 120sf no-building-permitrequired microhome with south-facing windows and a horizontal overhang provides seasonally desirable shading has been modelled with 2kw solar and a 5-kwh plug-nplay battery to sustainably power this wood frame building “finite element”, offering an AFFORDABLE 21st century housing solution. Calculations show an 87% improvement in Time-of-Day-Value energy use (“EDR2”) over the Standard Design compliant per the California Energy Code, the strictest state-adopted energy code in the US. This design, with micro-kitchen and bath with shower, costs estimates at $25,000 DIY built, and $50,000 contractor built. Accessory Dwelling Units in modular sizes planned for wood structural efficiencies in 288, 576, 864, and 1152sf versions are being added to the Green Template repertoire, along with stacked flats, townhouses, ‘carriage’ homes, and other housing & hotel types.
