Integrated Building Performance, Electrification and Solar Woodacre Anchor
Across Sustainable Spaces/Recurve, Harney Home Performance and Solar Solutions, SolarCity and subsequent work in South Carolina, Andrew helped assess, model and advance hundreds of solar, building-performance and electrification projects spanning thousands of sites and customer applications. His work evolved from hands-on building assessments and deep retrofits across California to nationally scaled, software-enabled programs integrating efficiency, solar, monitoring and early battery storage.
A 2011 home and art-studio retrofit in Woodacre, California, provides one tangible example. The project combined envelope improvements with heat-pump water heating and mini-split HVAC conversions, replacing documented propane and electric-resistance equipment while matching the remaining electricity demand with a 100% renewable utility product.

Integrated Building Performance, Electrification and Solar Woodacre Anchor
A career in integrated building performance
Across Sustainable Spaces/Recurve, Harney Home Performance and Solar Solutions, SolarCity headquarters and subsequent South Carolina work, Andrew’s experience spans hundreds of residential and commercial energy projects and thousands of sites, assessments and customer applications. The work covered building performance, energy efficiency, deep retrofits, solar, electrification, monitoring, modeling, EV charging and early storage integration.
From field assessments to national programs
At Sustainable Spaces/Recurve, Andrew helped advance whole-building assessment, retrofit and software-enabled approaches. Harney integrated that work with solar and project delivery. At SolarCity headquarters, he worked across solar, building performance and efficiency as services scaled nationally and evolved toward integrated solar and early Tesla Powerwall storage. His field experience extended across Marin, Sonoma, Napa, San Francisco, the East Bay and Silicon Valley, followed by wider California and national work through centralized teams, software and virtual assessment capabilities.
Woodacre in practice
The 2011 Woodacre project in Marin County combined a roughly 2,000-square-foot home with a separate art studio. Both received comprehensive air sealing and insulation. A high-efficiency heat-pump water heater replaced propane water heating. Mini-split heat pumps replaced electric baseboard heating and propane fireplaces, with a dedicated mini-split system for the studio.
Designing around the site
The shaded redwood setting limited onsite solar production, so the project selected Marin Clean Energy’s 100% renewable electricity product. Andrew’s Harney role connected building assessment, customer requirements, scope, technology selection, modeling, incentives and economics with engineering and installation teams. The renewable utility product describes the electricity supply; it is not an onsite solar installation.
Relevance for building owners today
Treating efficiency, electrification, solar, storage and controls as one system helps owners evaluate how improvements interact. Andrew’s approach considers the building envelope, HVAC, hot water, electrical loads, indoor air quality, solar potential, utility economics, incentives and storage options together, supported by expected-performance modeling and field testing or monitoring where applicable. Woodacre illustrates the approach within the larger career portfolio.
