This dataset contains an inventory of Cambridge's estimated community-wide greenhouse gas emissions for the year 2012. The data was created by DNV-GL, MAPC and the Environmental & Transportation division of the Community Development Department. It was created to establish a baseline for total emissions community wide per the City’s commitment to the Global Covenant of Mayors. It provides a baseline for the City to set reduction goals and track progress towards those goals over time.

Profiles of development projects that are subject to Section 22.20 – Green Building Requirements of the Zoning Ordinance. Green Building Requirements ensures that major new projects and substantially rehabilitated buildings are planned, designed and constructed using environmentally sustainable and energy-efficient practices. The green building ordinance uses sustainable building rating systems as a technical framework to ensure that buildings throughout the City achieve a higher level in building energy use and efficiency, sustainability, and resiliency but does not require certification.

5-minute interval electric data for the Cambridge Senior center located at 806 Massachusetts Avenue from April 2013 through July 2018. The dataset enables analysis of electricity usage patterns over a series of days, weeks, months and years; this can help identify opportunities to reduce energy use and demand and can be used as a starting point to correlate energy consumption changes with conservation measures.

Electricity use is the amount of electricity that has been consumed over a certain period of time. Electricity demand is the maximum amount of electrical energy that is being consumed at a given time. Electricity use is measured in kilowatt hours (kWh). Electricity demand is measured in kilowatts (kW). Additionally, this dataset contains measurements for Power Factor and Reactive Power. Power Factor is the ratio of the real power that is flowing to the load and the apparent power that is supplied to the circuit. Reactive Power occurs in alternating current circuits when there is a phase difference between voltage and current. It is measured in kVAR for demand and kVARh for use.

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 provides two key emissions figures for the building.

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.
