7 Must-Haves for a Hot House Makeover: Unveiling the Ideal Candidate for an Exterior Insulation Retrofit

Shawna HendersonNovember 09, 2023

A good time to do an exterior insulation retrofit is when it’s time to replace the siding or cladding. The best time is to do it when it’s time to replace the siding AND the windows. The best time to replace windows is when the siding needs to be replaced. Cladding, windows, roof. Replacement time means improvement time. Timing is everything. Not just for deferred maintenance, but also for the owner’s monthly budget.

Bonus Points for Blended Learning

There's a lot of times when face-to-face training is the only thing that will do. Especially in the home performance industry: hands-on is the only way you can really learn to identify and diagnose energy-sucking and moisture-growing situations in a house. But to understand what you need to identify and...

Here's something near and dear to the heart of anyone involved in the home performance industry: how to make energy efficiency sexy, appealing, and properly valued. When you're up to your eyebrows in insulation and you know that you are adding significant value to a house, it's sometimes hard to...

So much to know...

Shawna HendersonNovember 18, 2014

It's hard to wrap your head around the amount of number crunching that goes into energy analysis, and how to prioritize your time and effort when working on a project. There are energy modelling tools that can be used that make it easier, but in a lot of cases, the easier the modelling tool is to use, and the less actual, real-world performance testing data you input, the more likely the result will be a ball-park figure that doesn't relate to actual energy usage, or actual heating or cooling loads.

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).
