Energy Interval Data

The link below will take you to a site where various Interval Data reports for energy use are available. These are detailed technical reports and not intended for a casual user. If you’re looking for monthly energy use and cost information for a school, building and/or meter, please use the EnergyCAP reports described above. You will get the same data there as you used to get from Energy Witness

To access the Energy Interval Data site from a non-Harvard location, you must use a Virtual Private Network (VPN). After clicking on the link below, you will be brought to a pop-up to sign in. Please enter your Harvard Key UserName and Password.
