Dubbed Haus Am Hang, translation house on the hill. This 28,000 square foot lot at The Ridge in Pemberton, BC, has commanding views of the majestic Mount Currie and Pemberton Valley.
A Platinum Certified Built Green Canada project, this NetZero Ready home is built sustainably, keeping the embodied carbon in the construction methods as low as possible. As well as these two third-party energy and sustainability certifications, the home has also been built to Step 5 of the BC Energy Step Code, the highest standard of the BC Building Code’s energy efficiency compliance path.
A 3-level home over 4,200 square feet, with 5 bedroom, 4 full bathrooms and 1 half bathroom. It also features an extensive covered outdoor living space with design, engineering and services in place for easy to construct custom pool, built-in hot tub, and cabana with a second half bathroom for poolside convenience. The basement is partially finished, allowing for 3 separate designs. In-law suite, self contained suite, or media/rec room with wet bar, bathroom and separate bedroom.
A NetZero Home produces as much energy as it uses over the course of a year. To achieve this, a range of the most up-to-date mechanical, electrical, and construction technologies are employed:
• Insulated Concrete Formwork (ICF) for the foundation
• Prefabricated and highly insulated wall and roof panels made by BC Passive House, locally built in their state-of-the-art Pemberton, BC factory
• High-performance triple pane glazing from Innotech Windows + Doors, produced in Vancouver, BC
• Heat pump forced air system for space heating and cooling, with heat recovery and ventilation (HRV) for fresh air and comfort
• CO2 heat pump system for domestic hot water with drain water heat recovery (DWHR), the highest efficiency combination in water heating
• High-Performance envelope membranes by proclima, to ensure the building structure can withstand weather while remaining breathable
• Carefully sized roof overhangs to provide summer shading, whilst allowing for solar gains from the low winter sun
• Vegetated retaining wall system to lower the carbon footprint of site work, provide extra plant space and allow rainwater infiltration
• Construction waste recycling and tracking
• Green Guard hardwood with natural wool carpets
• Low or No VOC interior paints and finish products
The Integrated Design Process on this project was highly involved with the following teams:
• Building design and modelling inhouse by Coast Essential Construction
• Energy modeling by Capital Home Energy
• Structural engineering by Twin Peaks Engineering
• Prefabricated structural wood framed components from BC Passive House
For more information on the construction methods, assemblies, and technologies used on this project please see below.
The Coast Essential team as carefully selected building assemblies that are not only super energy efficient, but also have a low embodied carbon.
We at CEC take all the steps necessary to work through the Integrated Design Process and model all aspects of the home. From Structural, energy consumption, Effective R values and cost.
Below is an example of the basic exterior wall assembly. With an effective R value of 33.8(RSI 5.95) this takes the wall assembly to 51% more insulating value than a minimum code wall for Climate zone 5 (R-17.5).
