Building Performance Standards
Building Performance Standards (BPS) are policy tools that states and municipalities in North America are steadily adopting to enable decarbonization of buildings. A BPS is a policy that sets specific deadlines for existing buildings over a certain size to achieve quantified standards of performance across one or more metrics – such as energy use, water use, and/or greenhouse gas emissions. The policy defines compliance routes, which often include attaining the quantified standard of performance defined for them on a building-by-building basis (a performance compliance route), but can also include prescriptive compliance routes. Prescriptive compliance routes can be the completion of an energy audit, certain energy efficiency measures, or investing more than a certain amount on energy efficiency projects.
The Constellation Navigator Virtual Energy Efficiency team has partnered with the Institute for Market Transformation to receive up-to-date data on all building performance standards in the U.S. and Canada, which we process, package, and use for calculations. This data enables us to understand the compliance paths available.
The BPS Ecosystem
A building owner has warning signs of BPS programs being implemented. For a typical jurisdiction, the process looks something like this:
- Benchmarking Ordinance: All building owners in the jurisdiction are now required to report their building’s energy consumption or emissions.
- Commit to BPS: A jurisdiction publicly commits to passing a policy in the future that sets specific maximum energy usage or emissions targets for a specific subset of buildings. The subset of buildings is likely defined, so a building owner will know if they will be required to comply or not.
- Implement BPS: The policy is passed, and with that, the targets are solidified, and fine amounts and associated timelines are set in stone.
Buildings are now required to report their consumption/emissions yearly, and this reported number is compared with their target. If they are above their target when a fine year comes, they are liable for fines.
Reporting refers to the process of sharing measured energy usage data with a state or city entity. This is often mandated under a “benchmarking” policy, ordinance, standard, or law. Reporting is a key piece of any BPS program, as the jurisdiction needs to have a single source of truth for the metrics that determine a building’s compliance state.
The jurisdiction sets standards and requirements for the reporting process, which typically include:
- A centralized platform where the energy usage data is uploaded and tracked. This is typically EnergyStar Portfolio Manager (ESPM).
- Publicly accessible list of covered buildings. This typically includes a unique ID for each building. This ID often needs to be linked to a building in the centralized platform for ease of tracking.
- Guidelines for what constitutes the “submission” process. This typically includes sharing “view access” to the ESPM property with the applicable jurisdiction.
- Guidelines for calculating emissions using energy usage data, sometimes including assumptions for how the emissions factor of the electric grid will change over time.
- Guidelines on how third parties can complete this process for a building owner.
- Guidelines on how to engage utility companies to set up an ESPM account to automatically receive usage data as it is billed.
- A signed attestation of accuracy for whoever completes the process.
Depending on the utility companies in the area, the program details, and the building type, this process can range from taking 1 hour per year to 20+ and can often be confusing for building owners. Thus, it is typically given to someone with energy expertise, often to a third-party company if energy expertise doesn’t exist in the building owner company.
BPS programs often offer several pathways to compliance. The selection of the best pathway often requires a certain amount of data about the building and energy expertise. In some cases, the selection of a pathway must be shared with the municipality or state entity. Afterwards, compliance state can be checked.
-
Determine the best pathway:
Example - Colorado. Four pathways exist:
- Percentage reduction from an energy baseline
- Percentage reduction from an emissions baseline
- Meet a prescriptive energy target
- Meet a prescriptive emissions target
Example - Washington State.
- Complete an energy audit and the measures that pan out economically
- Meet a prescriptive energy target
The target that requires the least amount of effort will be the best target. That varies depending on the building and its current state. Understanding the best pathway often requires detailed calculations that can save a client a lot of effort.
-
Determine exceptions and submit pathway selection:
In some cases, programs require that pathways be specified in advance for a given building. Sometimes they don’t. If a building owner has hired a third party for this effort, the specification of a pathway will also be under the scope of work of that third party.
As part of this process, it is often required to apply for certain target reductions or even exemptions.
Programs offer exceptions for cases like vacant buildings or recently constructed buildings. Applications for exemptions entail correspondence with the program authority, data review, and certification of truth.
Programs offer target reductions for things like parking garages, process loads, or changes to the municipality’s understanding of the building, such as square footage. Applications for target reductions typically entail correspondence with the program authority, data review, and certification of truth.
-
Determine compliance:
The chosen pathway will determine which targets a building needs to hit, when, and what the structure of penalties will be for not being in compliance. Determining compliance of a given building requires several steps of calculations to be completed, and influences key client decisions moving forward.
- Finalizing target determination for each compliance year.
- Gathering reported energy usage and forecasting future energy usage.
- Considering a company’s acceptable risk profile in projecting whether or not a building’s reporting usage may exceed the target in each compliance year.
In cases where a building is not compliant with a BPS program for the foreseeable future, a plan must be made to gain compliance or face potential fines. Fine magnitude varies widely, resulting in scenarios where taking a fine is the most profitable option and in scenarios where fines should be avoided at nearly all costs.
- Determine which strategies are in scope. Depending on the program, certain strategies may count towards the target, while others may not. Yet others might only count partially towards the target (e.g., Efficiency, Rooftop solar, Renewable energy credits, Carbon reduction credits).
- Calculate reduction strategy impact. For each strategy that might be available, likely mostly energy efficiency opportunities, the impact of each strategy towards the target must be determined. The economics of each strategy must also be calculated, taking into account any available rebates, annual savings, and the lifetime savings of a technology. If an organization has additional sustainability goals, such as emissions reduction targets, that should be considered too.
- Choose compliance or non-compliance. Based on the cost of the optimal compliance strategy and the risk profile of the client, it can be determined whether compliance should be achieved, or the fines should be taken.
- Implement. If it is chosen to gain compliance, then the client must take action to install efficient equipment, build renewable energy onsite, or purchase credits. The timeline required for these actions will be determined by the timeline of the fines.

Address Check
Many BPS programs have public covered building lists (BCLs). With the VEE APIs, users can check if a building is or is not on the BCL of the BPS program in its area.
Get Targets
Regardless of whether or not a program has a public BCL, the Glimpse API can check for whether or not it’s likely to be subject to a BPS program using its Zip Code, Building Type (either using the EnergyStar PortfolioManager classification or the VEE classification), and Size.
First, the zip code is checked to see if it is located in any of the program’s applicable zip code lists. If not, then there is no applicable program. If so, the process continues.
Next, the building type (if given using the Department of Energy classification method with 16 building types) is converted to the EnergyStar schema, which most BPS programs use. The building is further classified as either commercial or residential (industrial buildings are out of scope for the Glimpse Calculator and of most BPS programs). Residential buildings are: Midrise Apartment and MFH (multi-family housing) in the Glimpse Data Definition and their relations in the ESPM data definition. Some programs also have different requirements for public buildings. The software treats all non-residential buildings as possibly either public or commercial to err on the side of caution when returning targets.

Third, the square footage and residential/commercial classification is checked against the boundaries of the compliance groups in the applicable program - many programs have different types of requirements depending on where a building falls with these two parameters. If there are requirements for the size and residential/commercial classification, then the building is likely required to comply with the program.
The final check is at the detailed building type level. Some programs have pathways that change depending on the type of building, for example, restaurants may not be required to reduce energy consumption at all but supermarkets may be required to do so. Additionally, some programs have different pathways for different building types, for example, an office may be required to meet a prescriptive EUI target, while a restaurant must meet a percentage reduction target.
Any pathways deemed possible will be highlighted as applicable. This may include two pathways, for example, one if the building was a publicly owned building, and another if it was a commercial building. Another example of this would be if the building has options, maybe a percentage reduction route and a prescriptive target route.
Pathway information returned from Glimpse always includes the following:
- A list of years in which compliance will be assessed
-
Targets (in both EUI [kBtu/square-foot per year] format and GHG [kgCO2e/square-foot
per year] format) in each year when compliance will be assessed.
- These targets to not take into account any manual target adjustments that may be possible within the program.
- They do take into account baseline information if the user has given historical energy usage.
-
Target information:
- The format of the target (EUI, GHG, percent reduction, etc)
- The associated pathway name
- How the program plans to calculate fines, alternative compliance payments, or other penalties based on the building’s performance in a compliance year, its baseline, and its target.
- Any applicable fines or alternative compliance payments if the building’s energy usage were to remain constant (in each year when compliance will be assessed).
- Any applicable fines or alternative compliance payments if the building’s energy usage were to fluctuate within reasonable bounds (in each year when compliance will be assessed).
Compliance Planning
If a BPS program is scoped in for a particular building, and the BPS program includes performance compliance pathways, the Glimpse API will return pathway information. If the building is currently above any of its targets, and the API call has separately requested that certain EIMs be calculated, the Glimpse API puts together possible strategies to reduce or eliminate fine risk.
Strategy creation consists of several steps:
- The life cycle impact of each EIM is calculated, including the first-cost, cost savings, energy savings, and emissions reduction.
- The most lenient pathway is selected by calculating the energy savings required to meet the final target and choosing the pathway with the least energy savings required.
- The first year of non-compliance is found. This is the first target year in which the current energy usage or emissions of the building is above the target.
- Next, all possible EIM combinations are calculated (see EIM packaging section). This excludes possibilities where EIMs are mutually exclusive, but does not take into account mutually dependent effects. For each EIM combination, the cumulative energy usage and emissions reduction are calculated.
- Out of all the combinations created, the EIM packages that do not meet the impending target are removed, the remaining packages are sorted by their combined economic performance (IRR), and the top performing package is selected.
- If the subsequent building performance, after EIM package implementation, does not reach future targets, the process repeats.
If strategies are calculated, three strategies are returned:
- Do-nothing strategy. No EIMs are completed.
- Low Risk Strategy. If possible, the projects are planned to always be at least 5 kBtu/sqft or 0.5 kg of CO2e below the target to minimize the risk of operations factors increasing energy usage or emissions.
- Low Investment Strategy. No buffer is given and projects are planned to be just below the impending target.
For each strategy, the Glimpse API returns the suggested projects, the year of project completion, the total IRR of the project (with and without taking into account fine avoidance), the cash-flow of the strategy including first-cost of each project and subsequent utility cost savings, the NPV of the projects, and the total gross cost and gross savings of the projects.
The strategies can only involve EIMs that were requested. If any targets are out of reach of the combined savings effect of calculated EIMs, the suggested strategies cannot avoid the associated fines - they choose instead to minimize them.
