The firm has found that the single most effective way to reduce fuel consumption is to convert building boilers from oil to natural gas. In addition to its reduced cost, natural gas burns cleaner and, therefore, presents less of a threat to the environment. Natural gas currently heats 64 percent of Castellan properties.
By contracting with the third-party engineering firm Bright Power, Castellan performs extensive energy audits on each of its properties. The recommendations of these audits have led to repairs and improvements that range from the optimization of HVAC distribution ducts to the installation of low-flow toilets.
