- [Commercial Energy Audit Checklist](https://monohousing.com/blog/checklist-for-commercial-energy-audit/): Quick Vision The whole page in six lines, before the detail. A commercial energy audit checklist has two halves: what the building owner prepares before the auditor arrives, and what the auditor inspects once on site. The preparation half determines the quality of the audit. Missing utility data or out-of-date drawings limit what any auditor can conclude, regardless of how thorough the site visit is. Two to three years of utility data across every fuel source is the single most valuable item on the list. Envelope items are the ones most often reduced to a visual note. Air leakage cannot be confirmed by looking at a wall; it requires a pressure test to produce a number. A checklist tells you what to look at. An audit tells you what each finding is worth in dollars and in years of payback. In British Columbia the ASHRAE framework still governs method, but the incentive and code context is provincial, which changes which measures are worth pursuing first.
- [BC Energy Step Code Part 3 Airtightness Requirements](https://monohousing.com/blog/part-3-airtightness-requirements/): Quick Vision The whole page in six lines, before the detail. A Part 3 building is over three storeys or has a footprint above 600 square metres. Below that threshold you are in Part 9 and a different set of rules applies. Step 2 has been the province-wide minimum for Part 3 buildings since May 2023. Step 1 was marked reserved in the code and is no longer a compliance path. A final airtightness test is required to obtain an occupancy permit. This is not optional and it is not satisfied by an energy model alone. Part 3 targets are expressed in litres per second per square metre of enclosure area at 75 pascals. ACH50 does not apply at this scale. There is no universal pass number. Your target comes from the energy model your Registered Professional submitted, which makes the modelling assumption the real requirement. The City of Vancouver operates under its own by-law and its own bulletin, so a project team working across municipal boundaries is working to two different rulebooks.
- [What Are Good Blower Door Test Results?](https://monohousing.com/blog/what-are-good-blower-door-test-results/): Quick Vision The whole page in six lines, before the detail. CFM50 is the raw measurement. On its own it tells you almost nothing, because a bigger building leaks more air at the same quality of construction. ACH50 is the number most people mean when they ask about good blower door test results. It divides leakage by the volume of the building. In British Columbia, 2.5 ACH50 is the practical benchmark for a new Part 9 home, because that is the Step 3 target and Step 3 is the province-wide minimum. Below 1.5 ACH50 is genuinely good. Below 1.0 is Step 5 territory. Passive House sits at 0.6. BC does not stop at ACH50. Compliance documents also report NLA10 and NLR50, and a building can pass on one metric while missing the others. A real example is walked through below. A number without a leak location is not actionable. The result tells you how much; it does not tell you where.
- [What Are ABAA Standards?](https://monohousing.com/blog/what-are-abaa-standards/): If you have opened a project specification and found the line "air barrier assembly shall comply with ABAA standards," you are not the first person to stop and wonder what that actually obligates you to do. The acronym is easy to confuse with two unrelated things, the association behind it is American, and the document trail is scattered across several ASTM test methods. This guide separates ABAA standards from the standards they are commonly mistaken for, lists the numbers that matter, and shows exactly how each requirement maps to the Canadian and British Columbia rules that govern real projects here. Because the final proof of performance is always a measurement rather than a certificate, it also explains where whole building airtightness testing fits into the picture.
- [ASTM E1827 Explained](https://monohousing.com/blog/astm-e1827-explained/): Uncontrolled air leakage can make a building harder to heat, cool and ventilate properly. Small gaps around windows, doors, attic hatches, service penetrations and envelope transitions may not look serious during a visual inspection, but together they can create drafts, comfort complaints and unnecessary energy loss.
- [ASTM E1186 Explained](https://monohousing.com/blog/astm-e1186-explained/): Airtightness testing can tell a project team how much air is leaking through a building envelope, but it does not always show exactly where those leaks are. For projects that start with Large Building Airtightness Testing, ASTM E1186 can become the next practical step: locating the leakage paths that need attention.
- [ASTM E3158 Explained](https://monohousing.com/blog/astm-e3158-explained/): Large and multizone buildings cannot always be evaluated with the same straightforward setup used for a small, single-zone property. Professional Large Building Airtightness Testing requires careful boundary definition, sufficient fan capacity and coordinated pressure measurements across different parts of the building. ASTM E3158 provides a standardized method for carrying out this work and calculating the resulting air-leakage rate.
- [ASTM E779 Explained](https://monohousing.com/blog/astm-e779-explained/): Air can pass through openings in a building that are too small to notice during an ordinary inspection. Gaps around windows, incomplete air-barrier transitions, service penetrations and poorly sealed joints can collectively allow a substantial amount of uncontrolled airflow.
- [Passive House vs Net Zero Home: Which Is Better in 2026?](https://monohousing.com/blog/passive-house-vs-net-zero-home-which-is-better-in-2026/): Passive House (Passivhaus) is a rigorous building standard developed in Germany that focuses on dramatically reducing a building's energy demand through superior design and construction techniques.

- [BC Energy Step Code Vancouver: Builder Permit Guide](https://monohousing.com/blog/bc-energy-step-code-vancouver-builder-permit-guide/): For builders in Vancouver, energy compliance starts long before the final blower door test. It starts at the permit stage, when the drawings, envelope details, mechanical system, ventilation plan, and energy model all need to tell the same story.
