The Twin Peaks Passive House + ADU was designed and built to remain resilient in the face of natural disasters. Fortunately, the same great building strategies and design that provide resilience also provide a home that is incredibly comfortable and healthy while also visually stunning. This home’s journey began with a desire to design and build a house that meets the rigorous standards of Passive House. Before beginning the design/ construction process, the homeowners had already spent countless hours researching ways to minimize their global climate change footprint. As with any Passive House, a large portion of this research was focused on building envelope design and construction. The wall assembly is combination of six inch Structurally Insulated Panels (SIPs) and 2x6 stick frame construction filled with blown in insulation. The roof assembly is a combination of twelve inch SIPs and 2x12 stick frame construction filled with batt insulation. The pairing of SIPs and traditional stick framing allowed for easy air sealing details and a continuous thermal break between the panels and the wall framing. Beyond the building envelope, a number of other high performance strategies were used in constructing this home and ADU such as: battery storage of solar energy, ground source heat pump technology, Heat Recovery Ventilation, LED lighting, and heat pump water heating technology. In addition to the time and energy spent on reaching Passivhaus Standards, thoughtful design and carefully chosen interior finishes coalesce at the Twin Peaks Passive House + ADU into stunning interiors with modern farmhouse appeal. The result is a graceful combination of innovation, durability, and aesthetics that will last for a century to come. Despite the requirements of adhering to some of the most rigorous environmental standards in construction today, the homeowners chose to certify both their main home and their ADU to Passive House Standards. From a meticulously designed building envelope that tested at 0.62 ACH50, to the extensive solar array/ battery bank combination that allows designated circuits to function, uninterrupted for at least 48 hours, the Twin Peaks Passive House has a long list of high performance features that contributed to the completion of this arduous certification process. The ADU was also designed and built with these high standards in mind. Both homes have the same wall and roof assembly ,an HRV, and a Passive House Certified window and doors package. While the main home includes a ground source heat pump that warms both the radiant floors and domestic hot water tank, the more compact ADU is heated with a mini-split ductless heat pump. The end result is a home and ADU built to last, both of which are a testament to owners’ commitment to lessen their impact on the environment.

Our inspiration for this home was an updated and refined approach to Frank Lloyd Wright’s “Prairie-style”; one that responds well to the harsh Central Texas heat. By DESIGN we achieved soft balanced and glare-free daylighting, comfortable temperatures via passive solar control measures, energy efficiency without reliance on maintenance-intensive Green “gizmos” and lower exterior maintenance. The client’s desire for a healthy, comfortable and fun home to raise a young family and to accommodate extended visitor stays, while being environmentally responsible through “high performance” building attributes, was met. Harmonious response to the site’s micro-climate, excellent Indoor Air Quality, enhanced natural ventilation strategies, and an elegant bug-free semi-outdoor “living room” that connects one to the outdoors are a few examples of the architect’s approach to Green by Design that results in a home that exceeds the expectations of its owners.

The West Town GreenStar Retrofit is a historic landmarked two-flat in Ukranian Village that was converted to an efficient, healthy, and modern single-family home, while keeping interior and exterior historic character details. Special emphasis was put on indoor air quality and indoor-outdoor connections. The design focuses on non-toxic materials, good ventilation, low energy and water use, and the biophilic health advantages of light and views of nature. The kitchen, work, and family zones have views of the sun-filled south garden, an oasis in the urban environment containing native plants and fruit trees, rain garden, vegetable garden, chicken coop, apiary, and a patio. Outdoor connection and daylighting are also optimized through the skylight on the top level which spills light down the staircase. The energy strategy began with thorough retrofit insulation and air sealing, and included high performance windows and doors, solar thermal (hot water) and solar photovoltaic (electricity production) systems which support electric vehicle (EV) charging and high-efficiency smart lighting and appliances. HVAC is supplied by a combination of radiant heat, mini-split heat pumps, and a conditioning energy recovery ventilation system (CERV).
