A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Projects across campus included new windows, water aerators, lighting upgrades, and more.
Larger Projects included:
New Cottages Summer 2022:
-Installed new more efficient controller for campus irrigation.
-Although the (4) new residentials homes that we built weren't LEED certified, we made them as efficient as possible, adding over R-30 in the wall cavities, caulking all wall stud joints to seal out any potential outside air infiltration.
Engineering Project (Kleinhecksel): Engineering students helped select an existing 100 year old home for redesign with the goal of transforming it to be as carbon neutral as possible. The projects being performed on this home include adding insulation to all exterior wall and attic, installing an air source heat pump and hybrid hot water heater for maximum efficiency, and adding solar panels to the south side of the house.
HBPW Program for Audits: We have participated in a housing energy audit program through our local Board of Public Works (Local Water and Electric Utility). We have performed these audits on nearly 20 Hope owned residential homes and plan to use the reports and their findings to prioritize the completion of projects that provide the greatest impact. Over the course of the year we plan to audit the remaining 60 campus owned homes.
Boerigter: Rather than building a new 10,000 sq foot building, the college committed to renovating an existing space on campus for our Career Center, Leadership Program, and Alumni Engagement groups. Through the course of the project we were able to upgrade elements of our HVAC system to make them much more efficient and reduce our energy consumption for this part of the building. As part of this project we implemented a centralized waste and recycling program to reduce the number of individual office containers and increase the recycling opportunities. We will now be implementing this pilot program throughout campus to help us achieve our goals of reducing waste.
CIT: Rather than building a new 4000 sq foot space for our IT department we have committed to renovating the existing space. We will be taking advantage of this renovation to make the space more efficient from an HVAC perspective as well as abatement of hazardous materials rather than leaving them in place. As part of the project we have chosen to reutilize existing furniture for another department on campus rather than buying new.
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 Michigan EGLE 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:

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
In 2022 a consultant was tasked with completing an energy audit and report to review the existing design, efficiency, and functionality of the natural gas systems at Hope College DeVos Fieldhouse. In addition to the gas audit, they also completed a thermal imaging study to help better understand areas for improvement in the central boiler plant on campus.
