Program Driven Staged Retrofits

Shawna HendersonApril 09, 2014

Mike Rogers, OmStout Consulting, started a conversation a few weeks ago about staging deep energy retrofits -- a very interesting conversation has been so far. I'm all about staged retrofits, myself. The opportunity to move many existing houses closer to low energy/net zero in a few affordable phases is much...

Scaling the picture

Shawna HendersonApril 03, 2014

There is so much to focus on when working in energy efficient, low energy, high performance, green, sustainable houses: materials, assemblies, performance, HVAC, energy sources. Broad categories like these can be broken out into a dozen subcategories each, then another dozen sub-subcategories again. And there's two sets of the top-level...

Fragments and knowledge gaps

Shawna HendersonFebruary 21, 2014

BHE is based on translating the knowledge we have about building science and energy efficiency in housing into a format that is accessible to those already working in the home building industry. Labourers, tradespeople, renovators and contractors, as well as those who are less hands-on but still involved in the industry: office managers, internal sales teams etc. As a set of crafts and trades that really grew into a commodity-based industry only after World War II, housing is still finding its feet as a cohesive industry. The many trades and interests that come together to build a house all have their own silos of expertise. As energy prices and environmental concerns have created the need for energy efficiency measures and green building issues, the fragmentation of the industry has continued. Now not only do we have builders, tradespeople, contractors and inspectors, appraisers and mortgage lenders, but a whole layer of techno-weenie evaluators, assessors, trainers, designers, and consultants (yes, I am wearing my appropriate hats).
