The joule house

Grandview

An energy efficient house built into the hillside, where budget, beauty, and performance find their balance.

The Grandview home was a true design-build — the owners shaped the vision, we made it buildable. Set into the hillside with a fully electric footprint and near-Passive House performance, it’s a home built around the clients’ values as much as their taste.

BUILD TIMELINE

LOCATION

Okanagan, BC

Windows & Light

Triple-glazed throughout; generous south and west-facing glazing — light and views by design.

Passive Solar

Deep overhangs, timber shade structure, and exterior solar shades control summer heat gain without sacrificing natural light.

Comfort

Radiant slab heat in lower level; individual bedroom controls; zoned forced air between floors.

Energy

Fully electric: induction cooktop, electric vaporizing fireplace, 20 kW solar PV roughed in on the roof.

Challenges & Context

The hillside site contributes directly to the home’s performance — thermal mass, solar orientation, and passive shading are as much a part of the design as the mechanical systems. The envelope reflects that: ICF foundation, R-24 walls, R-48 ceiling insulation, and a blower door result of 0.65 ACH — near Passive House standard. A cold-climate heat pump handles primary heating and cooling, an independent ceiling cassette serves the primary bedroom, and the HRV features individually selectable exhaust heads for precise room-by-room moisture control. This is a home where the architecture and the engineering tell the same story.
