This dataset contains compliance status and energy and water use data gathered under the Building Energy Use Disclosure Ordinance (BEUDO) program. Property details, energy use and water use data are submitted by property owners or managers whose properties are subject to BEUDO through an online tool called ENERGY STAR Portfolio Manager. Parcel level property information is obtained from the City of Cambridge Property Database.

Energy and water use information submitted by property owners and managers is shown for properties that first began reporting data on energy used in 2015. Energy use for the listed Data Year is required to be reported by May of the next year. Properties subject to BEUDO reporting include:
- nonresidential properties 25,000 square feet or more,
- residential properties with 50 or more units and
- municipal properties 10,000 square feet or more.

Reports may include data on one or more buildings. The specific building IDs included (from the Cambridge GIS Building Footprints layer) are listed in the Buildings Included column. The report level is the most detailed level of energy use available - if multiple buildings are included in a report, we do not have energy use on the individual buildings, only the group. Building IDs and what they refer to have changed over time, even for buildings that did not change. To ensure you are using only comparable data when comparing reports over time, you should only make direct comparisons for reports with the same Reporting ID.

Properties with no energy data included are those that were identified as being subject to BEUDO for the given Data Year, but which did not submit a report.

Note that the City of Cambridge makes all efforts to acquire accurate data from BEUDO properties. The data may still contain errors or omissions. Under the 2023 amendments to the BEUDO ordinance, reporters will be required to get third-party verification of their reporting data.

This dataset contains compliance status and energy and water use data gathered through the Building Energy Use Disclosure Ordinance (BEUDO). Property details, energy use and water use data are submitted by property owners or managers whose properties are subject to BEUDO through an online energy and water use benchmarking tool called ENERGY STAR Portfolio Manager. Parcel level property information is obtained from the City of Cambridge Property Database.

Energy and water use information submitted by property owners and managers is shown for properties that first began reporting in the 2015 BEUDO reporting cycle. These include nonresidential properties 50,000 square feet or more, residential properties with 50 or more units and municipal properties 10,000 square feet or more. In 2016, nonresidential properties 25,000 square feet or more began submitting reports for the first time and their data was disclosed beginning in 2017.

Please note that the “Property Type” column distinguishes reports based on whether they contain information about a single building or multiple buildings. If you are running summary statistics on this dataset, make sure to avoid duplicating data by filtering for “single” reports and “parent” reports. Child properties are buildings also included in parent reports. The “Buildings Included” column details what buildings are included in parent reports, with the first building ID indicating the parent property.

This data set combines information from eight sustainable building certification programs, including two City regulatory programs, to show the extent and location of sustainable buildings in Cambridge.

For inclusion in this data set, a building must meet at least one of the following criteria: receive approval from the City’s Article 22 regulatory process; receive certification from the Passive House program; receive certification from Enterprise Green Communities; or receive LEED certification under a LEED system that requires the whole building to meet sustainability standards.

Some buildings meet two or more of these criteria. Information provided about the applicable sustainable building programs for qualifying buildings includes certification levels, certification types, ratings, or scores. Additionally, this data set contains information about other certifications (ENERGY STAR, Fitwel, and WELL) that may apply to covered buildings. If a covered building participates in the City’s BEUDO regulatory process, this data set indicates that. More specific information about BEUDO building energy usage can be found in the separate BUEDO data set.

In this dataset, we use Cambridge GIS Building IDs as unique identifiers for certified sustainable buildings. Building IDs refer to one physical structure, even if there are multiple street addresses associated with that structure.
