Buildings on campus are controlled by a computerized energy management system. This system allows for constant monitoring and adjusts temperatures when buildings are not occupied during evenings and weekends.
Replacement of old boilers with more efficient units reduces energy consumption throughout the year.
Solar bollards are used on the grounds of the new Physical Science Building and at the new Indoor Tennis Center walkway, provide lighting with connection to the power utility.
The Housing Department is replacing old appliances with Energy Star appliances.
We are planning to install energy-saving occupancy sensors throughout buildings which will result in savings in electricity costs.
We are planning the installation of occupancy sensors on lighting in classrooms, hallways, and restrooms. We have completed BAL restrooms. The savings range from 50% reduction in energy depending on location.
We are presently using a Chiller Plant to increase cooling efficiency for the new Student Dorms. Energy reduction is estimated to be up to 25%.
Old Dominion University Facilities Management has completed 90% of the retrofit to t move the campus lighting from T-12 to T-8 bulbs, as well as replacing incandescent bulbs with CFL. The T-8 system is approximately 50% more efficient and CFL’s are approximately 75% more efficient.
ENERGY CONNECT ILR PROGRAM
Facilities participated in an energy demand response program which provided incentive for reducing energy use during peak demand hours.
Facilities participation in the program is expected to offset utility cost by more then $35,000.00 in 2010.
ENERGY REDUCTION DURING TIMES WHEN BUILDINGS ARE UNOCCUPIED
The level of lighting in Resident Halls is reduced during unoccupied periods (move in /move out) while maintenance is being conducted.
Temperatures are adjusted in order to save energy in unoccupied buildings.
Variable Frequency Drives & Cooling Towers
Old Dominion University Facilities Managements is in the process of updating / replacing cooling towers throughout the campus. One of the ways that we can increase efficiency and lower energy costs in a cooling-tower design is to utilize a variable-frequency drive (VFD) on fan motors. The fan draws ambient air in, pushing/forcing it through the tower and extracts heat from process cooling water.
Applying Variable Frequency Drives (VFD's) on cooling towers reduces energy consumption (lowers utility costs), reduces maintenance requirements (personnel & equipment replacement costs) and process water temperature stabilization are among the benefits.
As part of ODU storm-water management program, the Grounds Division monitors and cleans up trash that falls into the Storm Management Ponds.
Safe use algaecides are used during the summer months to maintain algae growth and to keep algae from flowing into the storm drains that empty into our rivers.
Establish sub-metering for better management and increased awareness, water is minimized.
The University is pursuing initiatives to conserve water and to develop opportunities for storm water management.
We presently have two cisterns located at Foreman Field and the Runte Quad. These cisterns are used to collect rain water from roof tops and parking surfaces and are used to irrigate the landscaping around the stadium and the Runte Quad.
The cistern at the Runte Quad is a 10,000 gallon fiberglass tank, designed to irrigate the approximate 1 acre quad. It collects water from the Scotland House roof. It has a redundant feed from the municipal water system should a drought occur. There is a computerized system that tracks information about collection/usage.
The Grounds Division has established two above ground water collection system that catch water from the rain gutter. This water will be used to water flower pots on campus. There are two in place at this time.
75% of shower heads in campus residences are low flow at 1.5 gallons per minute.
75% of spigots in wash basins are low flow.
We are replacing standard water closets with water reduction water closets where applicable.
We are testing low flow or waterless urinals at residence halls.
