1.7 Develop a Plan for Boiler "Dry Lay-Up"
FY11 Goal: Develop a plan to place boilers in a dry lay-up status. Identify facilities where this is required. Implement several lay ups in FY11.
Strategy 2: Improved Performance and Efficiency of University Building Systems
2.1 Establishand implement a campus wide building setback standard.
FY11 Goal: To develop and implement a campus wide setback standard for night and weekend building systems heating, cooling, and lighting set points to conserve energy. Implement for top 50 academic and administrative facilities on campus in FY11. Implement for remaining academic and administrative facilities during FY12.
2.2 Expand Continuous-commissioning and Retro-Commissioning programs.
FY11 Goal: Expand the Continuous Commissioning and Retro-Commissioning programs to establish a review of all eligible campus buildings on a six year cycle. For FY11, implement improvement actions identified by FY10 studies. Initiate studies on 10 additional facilities in FY11.
2.3 Increasethe utilization of Metasys Energy Management System to better manage building energy operations.
FY11 Goal: Increase the utilization of Metasys to reduce building energy use by managing facility heating/cooling operations through the use of system monitoring, setbacks, alarms. Increase the ability of the Facilities staff to operate campus buildings using Metasys to achieve this advanced level of operation.
2.4 Improvethe Preventive Maintenance Program for building energy equipment.
FY11 Goal: Improve the Preventive Maintenance Program for the AHUs, distributed chillers, coils, heat exchangers, pumps, boilers, and other equipment to improve equipment performance, efficiency and reliability. Increase the use of industry best practices and the use of predictive maintenance practices. Train Maintenance staff personnel as needed to achieve this goal.
2.5 DevelopBuilding Commissioning Standards for new Facilities.
FY11 Goal: Develop a set of Building Commissioning Standards, tailored to specific building types, to be utilized on all new facilities. FY11 goal is to develop a contract specification to utilize on University construction contracts for new facilities.
