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 15,958,305 Kilowatt-hours 54,449.74 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 47,074 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
101,523.74 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
1,323,729 Gross square feet

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:
The previous report was used.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.07 MMBtu per square foot 0.13 MMBtu per square foot
Baseline year 0.08 MMBtu per square foot 0.16 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
21.36

Optional Fields 

Documentation to support the performance year energy consumption figures reported above:
---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Though there are not any formal initiatives in place to shift individual attitudes and practices, education has been taking place through Facilities group meetings and word of mouth.

A brief description of energy use standards and controls employed by the institution:
SNHU continues to replace both fluorescent and compact fluorescent lights with LED's and add lighting control systems to buildings that do not have them. The University experiences savings through reduced energy usage of LED's and lighting controls allow the Unversity to introduce occupancy schedules, daylight harvesting routines, and special event lighting intensities. The Building Automation System allows the University to program occupancy schedules for various HVAC equipment and also allows to implement nighttime setbacks. Programmed routines for occupancy sensors also allow for energy savings. All ventilation equipment on new buildings utilizes and energy recovery wheel or tube pack for recovering energy in exhaust air streams. Variable Frequency Drives have been systematically added to hydronic pumping systems, ventilation supply, and return fans, and refrigeration compressors to allow for energy savings through equipment turndown, modulation, and load matching.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The University is replacing old technology with LED throughout campus.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
---

A brief description of co-generation employed by the institution:
Athletics has a cogeneration plant for 60 kW of electricity and domestic hot water heating and pool water heating.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
SNHU is performing re-commissioning on some buildings.
