EHSRAs EHSRAs : Environmental Health and Safety Retrofitting Audits

Purpose:• Document current building equipment and departmental ownership

• Motor specifications involved in HVAC control• Air filter locations• Ventilation pipe widths• Rooms served by air handling units (AHUs)• Location and areas affected by dampers• Model numbers for equipment & sensors• VAV box model number & box locations• Inputs & outputs of VAV (including location of device communicating info)• Areas affected by VAV • Number, model, & locations of light fixtures• Location of outlets & outlet specifications

Tasks:• Record building maintenance and operations information• Develop preventative maintenance procedures (ISO 50001)

Mock Project Timeline

Year 1

Employee Incentives to Promote Development

• Support from community leaders and departmental involvement in program are requested by Mayor & Energy Manager

• Raspberry Pi BACnet controlled training module is created with software consulting resources

Building Infrastructure Upgrades

• Gradual replacement or upgrade of ‘energy hogs’ • Implement standard practices to maintain & organize CAD

documents• Infrastructure upgrades with short simple-payback periods

are implemented

Data Management for Public Buildings

• Energy Manager and Data Analyst are trained on Energy Star Portfolio Manager

• Data Analyst is appointed and weather normalization equipment and techniques are established and purchased

• BACnet/Raspberry Pi Training for software developers• Record infrastructure/equipment ownership as

departments opt into program

Mock Project Timeline

Year 2

Employee Incentives to Promote Development

• CIT is implemented• Better Buildings Board is implemented• Raspberry Pi/BACnet training module is created• CIT is trained on BACnet/Raspberry Pi Module

Building Infrastructure Upgrades

• Gradual replacement or upgrade of ‘energy hogs’ • EHSRAs should be adopted by facilities and maintenance staff involved in Better

Buildings Energy Plan• Infrastructure upgrades with short simple-payback periods are implemented• Preventative Maintenance programs for HVAC are developed & implemented

Data Management for Public Buildings

• Data Analyst unveils first monthly report• Department or Facilities Managers take over responsibility for Energy Star

Portfolio Manager• BACnet/Raspberry Pi Training incorporate training module development for

software developers• Implement infrastructure/equipment ownership records as departments opt in• Simple energy-monitoring sub-meters should be installed to isolate department

ownership based on FIFO and departments with major potentials for energy savings

Mock Project Timeline

Year 3

Employee Incentives to Promote Development

• Life Cycle Costs for Procurement are implemented• Comprehensive report should review city building management

strategies and adjust budgets to meet energy reduction goals• CIT is trained on BACnet/Raspberry Pi Module

Building Infrastructure Upgrades

• Gradual replacement or upgrade of ‘energy hogs’ • Infrastructure upgrades with short simple-payback periods are

implemented

Data Management for Public Buildings

• EnPIs are approved by Continuous Improvement Team and submitted for approval to City Council to establish standard accounting practices for Green Funds

• Building and infrastructure ownership is used to track energy savings • Simple energy-monitoring sub-meters should be installed to isolate

department ownership based on FIFO and departments with major potentials for energy savings

Mock Project Timeline

Year 4

Employee Incentives to Promote Development

• Energy-savings EnPIs are reviewed by Continuous Improvement Team

• Quarterly acknowledgements and rewards are established by City and approved by Accounting

• Hold Energy Awards ceremony to celebrate success

Building Infrastructure Upgrades

• Building employee evaluations include environmental aspects such as involvement with EHSRAs

• Gradual replacement or upgrade of ‘energy hogs’ • Infrastructure upgrades with short simple-payback periods

are implemented

Data Management for Public Buildings

• Raspberry Pi downstream development must be evaluated based on current technologies

• Infrastructure ownership are used to document Green Funds and provide supplemental funds for departments

• Simple energy-monitoring sub-meters should be installed to isolate department ownership based on FIFO and departments with major potentials for energy savings
