This prefabricated 1,800 square foot Certified Passive House is designed and built by The Artisans Group, located in the rugged central highlands of Shaw Island, in the San Juan Islands. It is the first Certified Passive House in the San Juans, and the fourth in Washington State. The home was built for $330 per square foot, while construction costs for residential projects in the San Juan market often exceed $600 per square foot. Passive House measures did not increase this projects’ cost of construction. The clients are retired teachers, and desired a low-maintenance, cost-effective, energy-efficient house in which they could age in place; a restful shelter from clutter, stress and over-stimulation. The circular floor plan centers on the prefabricated pod. Radiating from the pod, cabinetry and a minimum of walls defines functions, with a series of sliding and concealable doors providing flexible privacy to the peripheral spaces. The interior palette consists of wind fallen light maple floors, locally made FSC certified cabinets, stainless steel hardware and neutral tiles in black, gray and white. The exterior materials are painted concrete fiberboard lap siding, Ipe wood slats and galvanized metal. The home sits in stunning contrast to its natural environment with no formal landscaping.

This home is built to the passive house standard and produces more energy than it uses on an annual basis. Learn more at our blog.

Interior view of the living room in the first Passive House in Milton Keynes. Designed for Milton Keynes Parks Trust, and completed in summer 2012, Howe Park Passive House is the probably the most airtight building in the UK, achieving 0.07 air changes per hour. This 5 bedroom family home replaced a burnt out derelict house with a house which was truly environmentally sustainable and at the same time aesthetically pleasing. The house was built for Milton Keynes Parks Trust who have rented it to a lucky family. It has been constructed from and clad with sustainable timber, the exterior cladding is Kebony. It has high levels of insulation, high performance triple glazing, exceptional attention to detail and minimal cold bridging. In addition, low VOC paints have been used on the interior to provide a healthy and comfortable home and the building orientation and form have been maximised for solar gain. Innovative details have been used throughout including the foundation detail where the timber sole plate has been eliminated. Ventilation is provided using mechanical ventilation with heat recovery ensuring fresh air to the house, with minimal heat lost, or the windows can be opened if wished. The minimal amount of heat needed is estimated to be below £75 per annum using direct electric heating which is offset by electricity produced from Photovoltaic panels (PV) on the roof taking advantage of the feed in tariff and making the house have almost zero fuel bills! The design also incorporated the following features: PV panels to offset electricity demand for the lighting and ventilation system. Water butt collects rainwater and overflow drains to pond in wood. Materials used for the house where possible have been selected for their environmental credentials such as sustainably sourced timber for the timber frame and cladding. VOC free natural paints & 50% recycled paint to feature wall. Specialist ecological advice was sort to ensure that existing wildlife, fauna and flora was protected and encouraged, the neighbouring orchard and meadow are to be revitalized. The kerbs and road gullies to make it safer for newts to cross the road. Reduction in car use encouraged by the provision of a secure cycle store and home office to allow residents to work from home.

WINNER - AIA/BSA Design Award 2012 - 2012 EcoHome Design Award - PRISM 2013 Award This LEED Gold certified vacation residence located in a beautiful ocean community on the New England coast features high performance and creative use of space in a small package. ZED designed the simple, gable-roofed structure and proposed the Passive House standard. The resulting home consumes only one-tenth of the energy for heating compared to a similar new home built only to code requirements.

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.

The artfully designed Boise Passive House is tucked in a mature neighborhood, surrounded by 1930’s bungalows. The architect made sure to insert the modern 2,000 sqft. home with intention and a nod to the charm of the adjacent homes. Its classic profile gleams from days of old while bringing simplicity and design clarity to the façade. The 3 bed/2.5 bath home is situated on 3 levels, taking full advantage of the otherwise limited lot. Guests are welcomed into the home through a full-lite entry door, providing natural daylighting to the entry and front of the home. The modest living space persists in expanding its borders through large windows and sliding doors throughout the family home. Intelligent planning, thermally-broken aluminum windows, well-sized overhangs, and Selt external window shades work in tandem to keep the home’s interior temps and systems manageable and within the scope of the stringent PHIUS standards.

The Pumpkin Ridge Passive House harnesses the simplicity of Passive House design to deliver superb comfort and efficiency at minimal added construction cost. The Pumpkin Ridge Passive House is no more expensive to own on a monthly basis than a conventional custom home, when monthly energy costs are considered alongside mortgage, taxes and insurance. Yet the high performance green building will consume 90% less heating energy and offer exceptional comfort and indoor air quality. The project, designed by Scott Edwards Architecture and built by Hammer & Hand, is one of six homes in the Pacific Northwest to be featured by Northwest ENERGY STAR® as a demonstration super-efficient home.
