Mass Save Data

Notes:
1. The zoom functionality on the map is compatible with Internet Explorer version 9 or higher.
2. These data represent a limited time period and are not representative of total historic program distribution, or total program effort in any geographic area, and therefore are not to be used to     project future program needs in any geographic area.
3. This data is sourced from residential and C&I customer profile studies (available here), which use gross savings and incentives data collected from a combination of PA customer tracking and     other vendor data (such as upstream lighting sales by store location) to geographically represent savings and spending across the Commonwealth. Usage data is calendarized to represent actual     usage (not billing) in a given month or year. The study data does not always tie directly to the PA customer tracking systems and DPU reported savings, which take into account other factors, such     as evaluation impact factors and attribution.
4. Since actual purchasers of bulbs through the residential upstream lighting core initiative are not known a model was used to allocate savings and incentives to the census block group level.     Behavioral savings were modeled at the block group level by assuming average monthly savings were attributed to participating households in each block group. The C&I data includes all     upstream lighting installs and savings that could be geocoded.
5. Municipalities may access municipal energy use and cost data for municipal buildings through MassEnergyInsight, a no cost tool provided to Massachusetts communities by the Massachusetts     Department of Energy Resources (DOER) as part of the Massachusetts Green Communities Program.
