Oregon BPS Compliance for Office Buildings

Office buildings are the largest category of covered structures under Oregon’s Building Performance Standard. Portland alone has roughly 60 million square feet of office inventory, the bulk of which exceeds the 35,000 square foot threshold and is squarely in scope for ORS 330-300 compliance. Add the rest of the Willamette Valley, plus Bend, Medford, and the Columbia River Gorge cities, and Oregon BPS will touch most of the state’s commercial office market between now and 2030.

If you own, manage, or lease space in an Oregon office building, this is the version of compliance you need to understand. For foundational information on what the BPS is, start with our overview.

What Office Building Owners Are Actually Required to Do

Oregon BPS requires covered office buildings to complete a four-step compliance process under ORS 330-300:

1. Benchmark annual energy use to the Oregon Department of Energy via ENERGY STAR Portfolio Manager—first reports were due January 2025
2. Complete an ASHRAE Level 2 energy audit following ASHRAE Standard 100 with Oregon amendments
3. Run a life-cycle cost assessment on every recommended energy conservation measure
4. File a Form Q compliance report by 2028 (Tier 1) or 2030 (Tier 2)

The audit and Form Q work is the technically demanding part. Benchmarking is administrative—once it’s set up in Portfolio Manager, it’s relatively easy to maintain. The audit is where the engineering analysis and recommendations happen. The life-cycle cost assessment is where you document why specific measures should or should not be implemented.

The Office Building Compliance Picture

Different office building types have different characteristics and BPS implications:

Office Building Type	BPS Impact
Class A downtown high-rise	High — captured by size; significant retrofitting and recommissioning opportunities
Class B suburban office	Captured by size; often the highest savings potential per dollar invested
Mixed-use office over retail	Captured if commercial portion exceeds 35,000 sq ft
Single-tenant corporate HQ	Captured; tenant typically drives compliance decision-making
Multi-tenant Class A in Pearl District/Lloyd District	Captured; landlord drives compliance under most lease structures
Suburban office park building	Captured per-building (not per-park) at 35,000 sq ft threshold
Medical office building	Captured; see our healthcare BPS post for nuances
Government office building (state-owned)	Separate state compliance track

The Lease Structure Question: Who’s Responsible?

This is the conversation we have with multi-tenant office building owners on the first call, and it usually surprises them. Oregon BPS compliance responsibility falls on the building owner, not the tenant. That’s true even when the lease structure puts utility costs on the tenant. The Form Q has to be filed by ownership, the audit has to be commissioned by ownership, and the ODOE compliance record sits with the property owner.

For triple-net lease structures, this creates a practical question about how to share information with tenants and how to coordinate any energy conservation measures the audit identifies. We typically recommend a tenant communication plan as part of the engagement, because tenants who understand the BPS context tend to cooperate with audit access requests and any disruption associated with measure implementation.

A Common Office Building Scenario: Beaverton Class B

A property manager at a 95,000 square foot Class B office building in Beaverton came to us in early 2026. The building was originally constructed in 1998, had a forced-air HVAC system that had been partially upgraded in 2014, and a building automation system that was mostly stuck on its original programming from two decades earlier. Tenant complaints about temperature control were common but manageable. The owners had assumed the building was reasonably efficient because of the 2014 partial upgrade.

Our ASHRAE Level 2 audit identified six significant measures:

• Chiller plant controls reprogramming (if applicable to building size)
• RTU economizer repair on roughly half the units
• Lighting and controls retrofit in tenant common areas
• Building automation system recommissioning
• Domestic hot water reset strategy
• Envelope sealing on original window assemblies

Total identified annual savings: $48,000 per year, with simple paybacks ranging from 1.2 years to 6.8 years across the measures.

The flat audit fee at the 75,000-100,000 sq ft bracket was $13,500. Energy Trust of Oregon at $0.85 per sq ft put $80,750 of potential incentive money on the table—meaning the audit fee was covered roughly six times over, with substantial dollars remaining to fund actual measure implementation.

That’s not an unusual outcome for a Class B Oregon office building. In our experience the buildings that look “fine” from the outside often have the largest energy conservation opportunities, because the maintenance and upgrade history hasn’t kept up with the building’s actual energy waste patterns.

What an Office Audit Actually Costs

We charge flat fees based on building square footage under ORS 330-300. No hourly billing. No percentage of identified savings. No contingency on results. For more details on pricing factors, see How much does an audit cost.

• 35,000-50,000 sq ft: $7,500
• 50,000-75,000 sq ft: $10,000
• 75,000-100,000 sq ft: $13,500
• 100,000-150,000 sq ft: $17,500
• 150,000+ sq ft: custom quote

For most office buildings, Energy Trust of Oregon incentives at $0.85 per square foot will cover the audit fee multiple times over. The net economics typically strongly favor the building owner.

What the Typical Office Audit Will Find

In our experience auditing Oregon office buildings, the most common high-value energy conservation measures are:

1. HVAC Controls and BAS Recommissioning — This is the single most common large savings opportunity. Building automation systems drift from their original programming over years and decades, and a thorough recommissioning routinely captures 8-15% reduction in HVAC energy. Economizer repair, ventilation optimization, and staging logic improvements are standard findings.

2. Lighting and Controls Retrofits — Especially in older buildings still running fluorescent or first-generation LED. New LED with appropriate controls (occupancy sensors, daylight harvesting, scheduling) is often a 1-3 year payback and generates significant annual savings.

3. Economizer Repair and Recommissioning — Outdoor air economizers fail or get disabled regularly, and the energy penalty is significant in the Oregon climate where free cooling is available much of the year. Many buildings leave economizers disabled when they could be running.

4. Envelope Air Sealing and Weatherization — Particularly on older buildings with original window assemblies and door seals. Infiltration is often much higher than assumed in design.

5. Domestic Hot Water Reset and Recirculation Strategies — Easy-to-overlook opportunity in office buildings where DHW recirculation runs continuously and heating is excessive.

6. Plug Load Management — Increasingly significant as office plug loads grow with equipment proliferation. Occupancy-controlled power strips and equipment scheduling can contribute meaningful savings. For details on what auditors examine, see ASHRAE Level 2 audit explained.

The actual measure mix depends on the specific building, its age, condition, and operational history. The audit’s job is to find them, model them, and produce a defensible life-cycle cost analysis on each.

Typical Office Building EUI Targets

Office buildings in Oregon typically need to achieve Energy Use Intensity targets in the range of 50-70 kBtu/sq ft/year to meet the BPS standard, though the specific target depends on the building’s particular tier classification and use category. These targets are challenging but achievable for most buildings through the combination of measures the audit typically identifies.

City-Specific Office Building Characteristics

Office building stock varies significantly across Oregon cities:

• Portland office buildings — Heavy concentration in downtown, Pearl District, Lloyd District, and Central Eastside. Mix of Class A high-rises, mid-rise Class B, and warehouse-conversion creative office. Urban transit access.
• Beaverton office buildings — Tanasbourne/AmberGlen corridor, Nike-adjacent, plus dispersed Class B stock. Heavy tech tenant base. Suburban character.
• Hillsboro office buildings — Concentrated around Intel and the Silicon Forest, plus Tanasbourne corridor. Tech R&D and corporate office. Campus-style development.
• Salem office buildings — Government-adjacent private office stock plus downtown commercial. Mixed age and condition.
• Bend office buildings — Smaller market but with disproportionate tech sector growth and tight commercial inventory. Mountain market characteristics.

What Office Building Owners Should Do in 2026

If you haven’t started, here’s the realistic 2026 sequence:

1. Confirm benchmarking data is filed with ODOE (verify 2024 submission status through ODOE records)
2. Confirm tier assignment (Tier 1 = 2028 deadline; Tier 2 = 2030 deadline)
3. Get flat quotes for the ASHRAE Level 2 audit from 2-3 qualified auditors for comparison
4. Apply for Energy Trust of Oregon incentives in parallel with audit kickoff to lock in peak incentive rates
5. Schedule the audit for completion in 2026 or first half of 2027 to allow 12-18 months for measure implementation
6. Use the remainder of the timeline to actually implement the audit’s recommendations, not just document them
7. File Form Q by your deadline with all supporting documentation, benchmarking data, and audit findings

The 2028 deadline sounds distant, but it’s only 18-24 months away. Buildings that haven’t started the audit in 2026 are already behind the timeline curve. Don’t assume you have time. You don’t.

Owner-Versus-Tenant Dynamics

For multi-tenant buildings, early and transparent communication with major tenants about the compliance requirement, the audit process, and any anticipated improvements is important and often required by lease provisions. Tenants who understand the context are typically cooperative with audit access, particularly when they understand the energy savings implications and timeline benefits. Building owners should:

• Notify major tenants early about the audit timing and potential disruptions
• Explain the energy savings that improvements might generate
• Coordinate access schedules to minimize disruption to tenant operations
• Share audit findings related to their specific spaces
• Involve tenants in improvement discussions that affect their lease space

This collaborative approach reduces friction and often gains tenant support for improvements that would otherwise face resistance due to temporary inconvenience.
