16
Good condition + efficient operation = no major changes Recommendations: Reduce outgoing steam pressure Phased transition to decentralized domestic hot water systems with a summer boiler in the Central Boiler Plant to provide steam for re-heats Replace the burner on Boiler #1 with a dual-fuel burner Campus Electric System Capacity and Description 17

Myrin Library Air handling unit ventilation rates are designed to maintain adequate ventilation during design occupancy levels. DCV sequencing through zone CO2 sensors enables reductions in ventilation air (and associated heating and cooling loads). This ECM can provide a rapid payback due to the large, open nature of the spaces. Replace the track metal halide lighting with LEDs 25
Replacing the current 1,500 W fixtures with LED fixtures (567 W each) will provide immediate energy savings. Additional savings will be realized through a reduced re- lamping frequency. Opportunities may also exist for bi-level lighting to provide safety while increasing output as needed. Lights currently operate all evenings. Provide occupancy-based operation at the Field House 26
Occupancy sensors are recommended at the field house to limit space lighting and index AHUs to a standby mode with relaxed setpoints and reduced fan energy. These control measures will be coupled with related components (eg daylight sensors for perimeter lights, CO2 sensors for ventilation savings). Optimize VAV Control
27 VAVs observed throughout use a staged method of heating in which airflow is increased when heating is required. While this can increase the VAV capacity, it also consumes a greater amount of energy input (related to heating, cooling and fan energy) per BTU of heat provided to the space. Optimized control can increase airflow only when this capacity is required or as needed to prevent stratification by supply air that is excessively warm. Energy Efficiency Measures Savings
