APPENDIX VII: 2022 MENG FACILITY CONDITION ASSESSMENT ENERGY INEFFICIENCY FINDINGS GRANTS PASS SUSTAINABILITY AND ENERGY ACTION PLAN 2022 MENG FACILITY CONDITION ASSESSMENT ENERGY INEFFICIENCY FINDINGS In 2021, the City of Grants Pass engaged MENG Analysis to complete a comprehensive Facility Condition Assessment ( FCA) in order to assist City staff in prioritizing maintenance needs and supporting proactive facility management. The surveyed facilities include 95 structures on 62 sites. The report identifies $7.2 million in total observed deficiencies to be addressed in the years 2022 -2027, and $19.5 million in long -term needs to be addressed in the years 2028 -2041. About 20% of the observed deficiencies ($1.4 million) relate to energy efficiency. The following information is an overview of the deficiencies in City facilities found in the 2022 Facility Condition Assessment that were related to energy efficiency. City Hall - $156,672 – p. 51 in FCA • Deficiency : Water cooling performed by well system heat exchanger and underground storage tank, corroded and leaking. • Remedial Action : Demo current system. Replace system with chemical treated, closed -loop closed -circuit -cooler (able to run as dry cooler and indirect evaporator) and add buffer volume to heat pump system loop (buffer for heating and cooling), tank in mechanical room. City Hall - $352,512 – p. 53 in FCA • Deficiency :Water -source heat pumps nearing end of useful life and contains phased out R-22 refrigerant. • Remedial Action :Replace water -source heat pumps.
