Operational cost savings go hand-in-hand with common green building measures:
energy savings from well-designed building assemblies
water savings from efficient fixtures and fittings
maintenance cost savings from durable and less-toxic finishes
However, if you look at the purpose of our buildings—to provide productive spaces for office workers, learning environments for children, and healing spaces for hospital patients—the biggest cost implications for buildings are those that affect occupants. In that light, additional green building strategies also make a lot of sense:
daylighting for greater worker productivity
ventilation and low-emitting products for better air quality, and test scores
Retrocommissioning or RCx can be a valuable tool for commercial building owners. RCx addresses the same scope as new building commissioning but is performed on existing buildings. RCx can improve building performance, save energy and money-especially for large buildings.
Between lighting, water use, mechanical systems, the building envelope, and occupant health, existing buildings are rife with cost-effective retrofits and operational opportunities that also offer environmental benefits. Improvements range from the painfully obvious to the more complex and involved.
