Homebuilder makes the argument for improved energy efficiency

In this mention

North Carolina homebuilders are blocking modernization of the state's energy efficiency standards, arguing stricter codes will make homes unaffordable. However, builder Rodney Graham and the Southern Alliance for Clean Energy argue that energy-efficient homes save money long-term and reduce carbon emissions. A federal study supports this position, estimating code updates would add $4,763–$6,057 to home costs but save owners about $335 annually in energy bills.
