Optional Fields

A brief description of the institution's water-related behavior change initiatives:

---

A brief description of the institution's water recovery and reuse initiatives:

---

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

At UMass Lowell, the consideration for green building is a priority. In UMass Lowell's Sustainability Initiative and Green Design Standards, as well as Plumbing Standards it is suggested that water use reduction specifications should be employed, specifically to "incorporate plumbing fixtures that are high efficiency or dual flush. Toilets, urinals and faucets should target 20‐40% less water usage than the listed baselines: Toilets 1.6 gpf, Urinals 1.0 gpf, Faucets 0.5 gpm or 0.25 gallons per cycle for metering faucets"

Data source(s) and notes about the submission:

The baseline year 2019 is the oldest available data with sufficient quality for use in this credit. The performance year 2020 is the most recent data available with a complete accounting of all water use available due to pandemic disruptions. The weighted campus user for each year is typical of UMass Lowell pre-COVID-19 pandemic operating environment, which differs from the information reported in PRE-5 (2021) that is the data used for the vast majority of this STARS report.

Employee and student information is based upon IPEDS reports. Resident individuals was provided by Residence Life and distance education numbers were provided by Institutional Research group.
