Energy Usage Standards
Definition of Standards of Performance for Building Systems:
A review of the building operation and maintenance practices has brought to light the fact that most buildings have no documented standards of performance for building system operation. Building operations and HVAC technicians must clearly understand the relationship between occupant requirements and system operation to meet such requirements. Definition of the building system standards of performance provides the Facilities staff with the necessary reference to operate and monitor system performance.
One example of a standard performance would be a winter/heating temperature level to be maintained at 70F±1F. Standards of performance can be defined for each building system. They must be understandable by building operators and mechanics and measurable for monitoring purposes. In the absence of standards, Facilities Department staff will continue to operate building systems in an attempt minimize complaints. Standards must be documented and incorporated into an operational energy management strategy for the University of Denver.
MEASURING OUR ENERGY USE
The Building and Grounds Committee of the University of Denver Board of Trustees believes it is the responsibility of the Facilities Department to ensure that every effort is made to conserve energy and natural resources while practicing sound financial management.
It is will be the responsibility of the Director of Facilities Management to develop and maintain an Energy Management Plan, develop specific guidelines and implement a program designed to achieve the efficient use of energy within the University of Denver, yet ensure a comfortable and pleasant learning atmosphere within each facility.
It is essential that energy guidelines be established and observed for the operation of the heating, ventilating, air conditioning (HVAC), lighting, other electrical equipment and water consumption. Every faculty, student and staff will be expected to contribute to energy efficiency. The Facilities Department will collect monthly information reflecting the energy consumption for the facility or group of facilities and will be responsible for tracking and reporting on the total energy (gas, electric, and water) consumption of the building(s). Every member of the University community will be asked to be responsible for implementing the guidelines for the areas they occupy.
To maintain an environment conducive to the educational objective of the University, the classroom temperature, when occupied, should be no higher than 70 degrees during the heating season and no lower than 72 degrees during the cooling season.
Heating, ventilation, and air conditioning systems may be fully operational only when the buildings are fully occupied. HVAC systems will remain on for activities in buildings normally designated to be set back or shut down by advanced notification (48 hrs) to Facilities Department.
- Night setback of thermostat controls should be 55-60 degrees during heating months.
- The custodial foreman at each site will be responsible for turning off lights in the facility after cleaning has been completed.
- Kitchen equipment will be operated according to shutdown guidelines.
- The Irrigation Shop will be responsible for campus irrigation according to seasonal guidelines.
Operating Heating, Ventilating, and Air Conditioning Equipment
- Heating and cooling equipment will be activated no earlier than necessary each morning to allow temperatures for reach adequate levels by the time occupants arrive. This operating time will be adjusted for seasonal variations.
- Cooling devices will not be activated before May 1 of each year, and will be turned off by October 1. Seasonal weather patterns and utility billing cycles will be considered.
- It is the responsibility of faculty and staff to close all windows and outside doors when the HVAC system is operating.
- Heating, ventilation, and air conditioning equipment should be turned off within thirty minutes after scheduled activities in the building have ended.
- Exhaust fans will be turned off when a building is not occupied.
- Facilities Director will coordinate with the HVAC Shop Foreman, Electric Shop Foreman and HVAC staff to develop a plan for turning the HVAC units on in phases to prevent unnecessary electrical demands.
Operating Lighting Equipment
- Refrain from turning lights on unless needed.
- All unnecessary lighting in unoccupied areas should be turned off. All lights will be turned off when students and faculty leave the classrooms.
- Outside lights will be off during daylight hours.
- Custodians will light only the specific area in which they are working.
Operating Electrical Equipment
- Computers should be operated according to computer guidelines.
- Electrical office equipment (computers, etc.) should be turned off when not in use.
- Copiers should be turned off at the end of each day’s use.
Operating Gas Fired Equipment
- Boilers and pilot lights will be turned off in those buildings without reheat coils or domestic hot water demands.
The University of Denver is strongly committed to conserving electricity, fuel, and water. The Department of Facilities has the responsibility of managing utility usage. The high cost of energy is a matter of particular concern throughout the University community. Since 1976 the University has funded several energy conservation projects that have been put forth by the Facilities Management Department. These projects have made it possible for the University to have one of the lowest BTU consumption and KWH consumption among the peer group institutions that we annually compare ourselves to.
Energy Conservation needs to be a campus wide goal. Some things you can do to help save energy are:
- Avoid using personal space heaters. Such heating units us a lot of energy, cause breakers to trip, and are dangerous if left unattended. One space heater can consume the same amount of power that it would take to run fifty-six four foot fluorescent lamps.
- Turn off lights when leaving offices, classrooms, and conference rooms, where safe and practical
- Turn off PCs, monitors, printers, copiers, coffee pots, and lights every night and on weekends. If you can’t turn off the whole computer, turn off the monitor and the printer. Enable the sleep settings on your computer monitor. Screen savers do not save energy but screen savers do.
- If appropriate, use in-jet printers; they consume 95% less energy than laser printers. Similarly, laptops use 90% less energy than desktop computers.
- When purchasing PCs, monitors, printers, fax machines, and copiers, look for Energy Star models
- In your dorm or apartment: Unplug appliances that are not being used. Most idle appliances such as TVs, VCRs, CD players, cassette decks, cordless phones, and microwaves continue to consume energy when switched off and account for 5% of total domestic energy consumption.
- Close blinds (and windows) after sunset in the winter to keep in heat. Leave them open during summer days instead of turning on extra lights.
- Take shorter showers. Showers account for two thirds of water heating costs.
- Run full loads of laundry instead of partial loads.
