“the feds put out the program for the green homes right they're going okay we're going to spend this money”
“we had a developer involved locally who was kind of a front-runner and a leader as far as Net Zero”
“I was thinking about a post I seen on LinkedIn this winter I think it was esport properties did a test”
“when the 2020 code went out for public consultation it had mandatory blower door testing in it”

// LESSONS FROM LMMW Group Ltd.
Sequence net-zero upgrades by demand reduction first: super-insulate, right-size windows, right-size mechanicals, then offset residual load with renewables — in that order.
Splitting capital and operating budgets across different entities (province builds, school board pays bills) is the structural root cause of under-investment in building energy performance.
Developers with tenant-paid utilities have a rational incentive to build to minimum code; removing that misalignment requires either mandatory labelling or split-incentive reform.
BC’s step code — a pre-announced ratchet of air-tightness and insulation targets every 3–5 years — is the most replicable model for driving industry-wide performance improvement without market shock.
Mandatory energy labelling at point-of-sale is the single fastest behaviour-change lever for the existing housing stock, provided it is phased in starting with new construction.
Air-tightness is the highest-ROI first step in any retrofit because it reduces the demand on every downstream system — mechanicals, renewables, and insulation all shrink.
// SELECTED PROJECTS
Souls Harbour Rescue Mission energy retrofits
In progressEnergy/facility condition assessments, deep energy retrofits, and L360 preventative maintenance for the charity's facility portfolio
Confirmed by Nova Scotia Power (utility) article dated 2024-09-20, which quotes Chad Wiesner as 'Founding Partner of LMMW' and the mission's COO Cherry Laxton; rebates via Efficiency Nova Scotia. LMMW's own project page describes it as ongoing across a diverse portfolio (assessments through retrofits and ongoing maintenance), so status is in_progress rather than a single completed job.
Bayers Lake Industrial Centre (Net Zero)
CompletedSubcontractor to builder Lindsay Construction: solar PV design-build (~535 kWdc roof-mounted), energy modelling, and CaGBC Zero Carbon Building Design certification support
LMMW project page (CMS slug 'windsor-elms-village' but page content is Bayers Lake Industrial Centre). Owner Skyline Industrial REIT held a ribbon-cutting in 2024 and construction completed Dec 2024 (status freshness-checked 2026). Pursuing CaGBC Zero Carbon Building Design Standard.
Parkton Wellness Centre
In progressOngoing facility management, facility services/upgrades, HVAC maintenance, and L360 Preventative Maintenance Plan
First-party LMMW project page; describes an ongoing facility-management engagement (not a one-time build), hence in_progress. No independent corroboration or dollar value located.
