WARTIME IN RITCHIE

Stuart and his wife, Meg, embarked on a deep energy retrofit project, which encompassed the complete renewal of a modest 1943 mature neighborhood wartime home into a healthy, comfortable, and energy efficient home. We've achieved an 80% reduction in energy consumption through exterior super-insulation and airtightness (0.25ACH@50Pa), as well as new highly efficient HVAC systems.

This blog chronicles the progression of our project.

We're now 4 years into the process, and have completed a major interior renewal involving all new services, structural and amenity improvements, new cavity insulation, and new finishes.  The exterior retrofit is complete as well. At this point, we're picking away at the remaining interior finishing details and planning new landscaping for Summer 2017. Pictures incoming...
