HISTORY OF ENERGY CONSERVATION
The Coral Gables campus is a very dynamic and expanding landscape. The infrastructure and the facilities are constantly changing and growing to meet the needs of the students, Faculty, Staff and Visitors of the University. Energy costs are a substantial portion of the operating budget, requiring careful and constant scrutiny. Energy Conservation practices, efficient equipment operation and maintenance has been a part of the Facilities Operating Plan for well over 18 years.
For the purpose of the Baseline comparisons FY-09 has been established to be our base year. From FY09 to FY13, the campus consumed 362 Million Kilo Watt Hours (Mkwh). This represents an annual average consumption of 72 Mkwh per year or an annual decrease of approximately 5.2% in yearly consumption as compared to our base year FY09.
FY13 represents our most successful Electricity energy savings over this term. The Total consumption for FY13 was 68 Mkwh representing a 9% consumption savings as compared to FY09.
Electrical Conservation Actions (Past & Current):
The majority of quick payback energy saving actions has been accomplished. Going forward additional savings will be attained through careful monitoring and analysis of building systems and utilities consumption data, resulting in modifications and adjustments of existing building systems to maintain and improve energy consumption efficiencies.
Electrical consumption reduction has been the main focus over the past 5 years. Significant energy conservation improvements and activities during this period have included:
- Construction of new LEED Buildings.
- Improved management of our Utility Plants CHW loop control strategies and set points to reduce the cost of Chilled Water production.
- Refrigerants upgrades to improve our chilled water loop system performance.
- Interior Lighting retrofit from T12 to T8 lamps with electronic ballast.
- Exterior LED and CFL lighting retrofits reducing wattage.
- Occupancy sensors in all buildings.
- BACnet EMS installation.
- Utility Plants upgrade of chiller to High performance energy efficient units to address additional load.
- High Efficiency Motor replacements.
- Campus wide efficiency setback of thermostats during campus break.
- Establishment of a campus Wide Set point of 74 Deg (+/- 1.5)
- On-going routine and preventive maintenance of building mechanical systems equipment to maximize their efficiency.
- Energy Audits: FPL in 2011 found the campus to be advanced in energy saving activities and improvements.
FUTURE ELECTRICITY CONSERVATION ACTIONS:
- Continue load shifting to off peak hours.
- Continue including lighting retrofits, EMS and multi-zone Variable-Air-Volume HVAC systems, Variable Frequency Drives on Air Handler Units and pumps on major and minor building remodel projects as appropriate.
- Continue Interior lighting retrofits as equipments fail.
- Continue installing occupancy and daylight harvesting sensors where applicable.
- Continue installing converting exterior lighting from timers to photocell.
- Continue High Efficiency Motor replacements as motors fail.
- Continue EMS retrofits during major remodels.
- Consolidate off period activities into selected energy efficient buildings so less efficient buildings can be set to unoccupied status.
- Expand “Energy Saving Awareness Campaigns”
The following is a list of energy conservation initiatives and best practices implemented by the Energy Management department.
HVAC is a major component of the total energy expenditure in a building, Campus Facilities are heavily reliant on the utilization of air conditioning and humidity control systems. Chiller plants are major systems that produce refrigerated chilled water needed to deliver air conditioning to commercial/ institutional buildings. Our Chiller Plant initiatives include:
■ Expansion plan to increase central chilled water plant production to eliminate inefficient standalone equipment.
■ Migration and expansion of campus wide Energy Management Systems (EMS).
■ A robust preventive maintenance (PM) program ensures the equipment operates optimally and extends its useful life.
■ Curtailable electrical rate in exchange for the ability to shut down utility plant equipment during periods of peak demand.
■ Monitoring of equipment run times to adjust to the academic calendar needs.
■ Modification of operational schedules to reduce equipment run-times (ex: cleaning schedules).
■ Coordination with the Office of the Registrar to complete shutdown of select buildings.
■ Ongoing benchmarking and programs to perform test and balance to ensure equipment optimization meet building demands.
■ Monthly energy reporting to monitor building occupant energy consumption.
BUILDING MECHANICAL SYSTEMS
Building mechanical systems consist of equipment needed to distribute chilled water to air conditioning equipment, and in turn distribute conditioned air to the occupied spaces within the building. Our Building Mechanical Systems initiatives include:
■ Use of Energy Management Systems (EMS) to monitor and adjust equipment run times to satisfy building needs.
■ Implementation of efficiently engineered mechanical systems such as Variable Air Volume (VAV) systems.
■ Installation of Variable Frequency Drives (VFD) in air conditioning and pump motors.
■ Installation of energy recovery systems that use return air energy from the occupied space to assist in conditioning incoming fresh air.
■ Implementation of a robust preventive maintenance program to ensure equipment optimization and extend useful life.
■ Standardization of room temperatures throughout all campus buildings
Interior lighting is a major component of the total energy expenditure in a building and is heavily reliant on the utilization of automated lighting systems and controls. The Interior lighting retrofit initiative / program objective is campus-wide for buildings and facilities in the standards, design of lighting and implementation of energy efficient lighting technologies. Our Lighting Systems initiatives include:
■ Installation of occupancy sensors in restrooms, common areas, hallways, offices, and classrooms.
■ Elimination of all T-12 fluorescent lamps and magnetic ballasts and conversion to T-8 fluorescent lamps with electronic ballasts.
■ Elimination of incandescent lamp uses and purchases on campus.
■ Program to install Light Emitting Dioxides (LED) lamps and compact fluorescent (CFL) lamps for improved energy savings and lighting quality.
