A list of permits for the installation of solar panels on buildings in Cambridge.

The Zoning Ordinance’s Section 22.20 – Green Building Requirements ensures that major new projects and substantially rehabilitated buildings are planned, designed and constructed using environmentally sustainable and energy-efficient practices. Projects fall under these requirements when:

• They exceed 25,000 square feet of gross floor area AND
• Require a Special Permit under any provision of the Zoning Ordinance OR
• Are subject to Section 19.50 – Building and Site Requirements

The City of Cambridge does not mandate that projects achieve Certification through a green building rating program. Rather, the intent of the green building ordinance is to use green 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.

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.

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.
