Fog carries salt that accelerates corrosion on condenser coils and electrical connections. Coastal humidity fluctuates 30 percent or more between morning fog and afternoon sun. Buildings in the Financial District, South of Market, and Mission Bay face particularly aggressive conditions. Older buildings lack vapor barriers and sealed envelopes. Moisture infiltrates through single-pane windows and uninsulated walls. Standard comfort cooling cannot maintain the stable conditions precision equipment requires. Server rack cooling systems must compensate for environmental factors that inland facilities never encounter.
San Francisco's construction timeline matters. Buildings erected before seismic retrofitting requirements lack the structural provisions modern precision cooling demands. Electrical systems designed for 1990s office loads cannot support current server densities. We work extensively with historic buildings downtown where adding capacity requires creative engineering and careful permitting. Local expertise means understanding which approaches building officials will approve and which create permit delays. Twenty years installing server room air conditioning across San Francisco gives us relationships and knowledge that outside contractors cannot replicate.
