Marin Civic Center HVAC System Assessment

This is a completed assessment project. You are in the Archived Projects section of the website. Active projects can be found on the Projects webpage.



Marin County Civic Center air handling units, and supporting HVAC components, are reaching the end of useful life; 96% of AC units are original to the building. The HVAC System Assessment was conducted to determine an overall refurbishment/replacement plan taking into account all equipment as an integrated system. The assessment considered overall cost, energy efficiency as it relates to the Marin County Climate Action Plan 2030, and new or retrofit equipment that will meet industry standards for durability and life expectancy. The final report presented a recommended plan and a multiyear capital plan for design and construction.


Estimated $200,000 and funded by the Capital Improvement Program fund.
