At PORTLAND INTL AP, OR US, the lowest monthly mean temperature normal is 41.6°F in December, and the highest is 70.6°F in August. These are 1991–2020 station averages, not daily extremes or conditions measured at your Vancouver building. [1][2]

Vancouver, WA: Washington versus Oregon requirements.
An HVAC planning brief for Vancouver, WA teams working on Washington versus Oregon requirements, with a cited seasonal reference, a practical evidence checklist, and clear limits on what is known.
Keep a Vancouver, Washington project’s legal and utility records on the Washington side of the river even when a Portland weather station is useful for seasonal context. Verify the parcel authority and state program directly instead of borrowing Portland reporting or permitting instructions.
Jurisdiction: Vancouver, WA. The station below supplies regional climate context only; parcel authority, utility territory, and local-policy applicability remain to be confirmed.
Local-policy review pending. This public planning brief includes sourced context and a usable checklist, but does not establish local requirements. Confirm current rules with the responsible authority before acting.
SEASONAL REFERENCE // NOAA STATION DATAA seasonal reference.
A seasonal reference.
Not a sizing rule.
Use this record to frame operating questions for Vancouver, WA, not to select equipment or predict the next season. It describes one regional station, not every neighborhood or building.

Source completeness: Standard (S); 27–29 years used across the displayed values. NOAA may fill missing months from nearby stations according to the stated quality class. Read the field definitions [3].
We reproduce the published monthly fields directly. No building load, annual energy consumption, forecast, humidity measurement, or local-policy conclusion is calculated from this table.
01 // PUBLIC-SOURCE FACTS
What the available evidence supports.
Source statements, not a determination about your building. Regional climate and national methods are identified separately from local-policy evidence.
The station’s highest monthly heating degree-day normal is 726.9 in December; its highest cooling degree-day normal is 181.0 in August. Both use a 65°F base. Degree days describe outdoor temperature departures, not equipment capacity, energy cost, or indoor comfort. [1][3]
EPA describes benchmarking as comparing a building’s energy use with past consumption, similar buildings, or a reference performance level. This building-level context is different from identifying a failed asset or confirming a city reporting requirement. [4]
02 // OPERATOR CHECKLIST
Turn context into an evidence record.
Our planning synthesis. These steps are not additional city requirements.
Reconcile the HVAC asset and meter record- Define one decision for Vancouver, WA: Washington versus Oregon requirements. Record the actual property address, business impact, decision owner, and what evidence would change the next action.
- Map every electric and fuel meter to the building, shared plant, and tenant area it serves. Record missing periods and the person authorized to request them.
- Collect the property identifier, use, floor area, current program document, and written applicability response. A utility-data export is not a compliance determination.
- Assign the submission owner separately from the technical reviewer. Retain a reporting receipt without presenting it as proof of equipment efficiency.
- Use the December and August station reference periods to frame seasonal questions. Compare actual utility periods and on-site records; do not substitute the normals table for measured site weather or design conditions.
- Deliver this working record: A Washington jurisdiction cover sheet with utility contacts and an explicit list of Oregon assumptions excluded from the project. Assign a named owner and a due date to every unresolved item; leave unsupported conclusions explicitly open.
TAKEAWAY // THE RECORD TO LEAVE WITH
A Washington jurisdiction cover sheet with utility contacts and an explicit list of Oregon assumptions excluded from the project.
Minimum fields: asset or property ID, observation, dated source or attachment, open question, accountable person, next decision, and due date. This is a suggested working record—not a city-issued form.
03 // DIRECT ANSWERS
Questions before the next decision.
What can the Vancouver climate table tell an HVAC operator?
It shows the seasonal pattern at PORTLAND INTL AP, OR US, using NOAA’s 1991–2020 normals. It can help choose contrasting periods for an operating review. It cannot establish current weather, extremes, humidity, indoor conditions, a building load, or the correct equipment size. Use site measurements and qualified design work for those decisions. [1][2]
What evidence should the Vancouver team prepare first?
A Washington jurisdiction cover sheet with utility contacts and an explicit list of Oregon assumptions excluded from the project. This is our recommended planning artifact, not a municipal form. Pair it with the bills and basic building information needed for a building-level benchmark, then identify the technical and authority questions that the benchmark cannot answer. [4]
Does this brief establish Vancouver, WA reporting rules or incentive eligibility?
No. The Portland airport station is in Oregon and is used only as a regional climate proxy for this Washington planning brief. The sources here support regional climate context and national benchmarking methods only. Obtain the current local or state document and an account- or property-specific response before acting on a threshold, deadline, exemption, permit, or incentive. Local-policy review remains pending; this public brief is planning guidance, not a determination of applicability. [1][4]
