Total site energy consumption per unit of EUI-adjusted floor area per degree day, performance year:

28.70 Btu / GSF / Degree-Day (°F)

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	24,437,151 Kilowatt-hours	83,379.56 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	581,105 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

664,484.56 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

1,625,506 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	Jan. 1, 2005	Dec. 31, 2005

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

2005 is the recommended baseline year.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.27 MMBtu per square foot	0.36 MMBtu per square foot
Baseline year	0.41 MMBtu per square foot	0.51 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:

29.33

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

May 2018 - projects across campus included new windows installed in Ross and Visscher cottages. Maintenance free, energy efficient and attractive!

A brief description of energy use standards and controls employed by the institution:

Hope College uses set points of 72 degrees in the winter and 75 degrees in the summer. The buildings are also controlled by occupancy sensors or occupancy schedules.

Some practices shared by our CIT Team:
Local virtualized server environment that consolidates data center functionality onto a minimum number of devices and allows for lower HVAC load.
Software as a Service (SaaS) solutions are the default for new projects, moving load from local data centers to highly-efficient facilities.
Automatic shutoff for projectors in classrooms.
Solid state storage in all new PC purchases reduces cooling needs and lowers electrical consumption.
Robust learning management system that allows for electronic distribution of content in lieu of printing
Recycling of all campus electronics as well as employee/student personal equipment through MI DEQ registered facility

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Hope College utilizes LED technology in all new and renovated construction projects.

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

Jack H. Miller Center for Musical Arts and Kruizenga Art Museum utilize a passive solar heat technology in the lobby area.

Local virtualized server environment that consolidates data center functionality onto a minimum number of devices and allows for lower HVAC load.
Software as a Service (SaaS) solutions are the default for new projects, moving load from local data centers to highly-efficient facilities.

A brief description of co-generation employed by the institution:

n/a

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Major projects include:
DeVos Field House - replaced sport compact fluorescents with LED fixtures over its entire three basketball court system.
DeWitt Tennis Center - replaced lights with LEDs
