47.90 Btu / GSM / Degree-Day (°C)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 24,897,689 Kilowatt-hours 84,950.91 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 0 Kilowatt-hours 0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 68,441 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
153,391.91 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
150,798.11 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period July 1, 2017 June 30, 2018

A brief description of when and why the energy consumption baseline was adopted:

Performance year 0.78 MMBtu per square meter 1.57 MMBtu per square meter
Baseline year 1.02 MMBtu per square meter 2.22 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
29.59

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Roger Williams has an on-campus group of Peer Leaders, known as the EcoReps, who are involved with sustainability initiatives across the University. They are charged with promoting and educating the community about sustainability --including the conservation of energy and water.

Additionally, the University recently (April, 2018) established a University Sustainability Committee, coordinated by the Steering Committee, which is broken up into seven sub-Committee's. One of the sub-Committee's, Energy, is focused entirely on energy consumption of the University. The primary goal of the Committee is to develop and review proposals for sustainability initiatives.

A brief description of energy use standards and controls employed by the institution:
We are also in the process of upgrading our Energy Management System with all new updated building components, controls, hardware and software. This will make controlling the energy usage by building even more efficient.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
We have been converting all lighting fixture to LED for many years through National Grid Energy Programs and through vendor programs. See attached document (Current LED upgrade project) that details the latest initiative we are undertaking to continue with the LED upgrade and installation of lighting control systems in the buildings. Our goal is to have this project completed within nine months and no later than January 1, 2023, as required by National Grid for this incentive program specifically. Our goal is to be 100% LED with no incandescent lights remaining on campus within the next couple of years.
