A campus building that recently earned LEED Gold certification undertook a similar review of its eligibility under the LEED NC module. With a 37% improvement in EUI over code, it readily surpassed the 25% performance benchmark threshold requirement. Reflecting the building’s small size, the 7 tons of CO2 per year that would be generated in credits nonetheless generated a 1.5-3% return on incremental capital, comparable to the value of utility incentives on the region, based on the $3/square foot that LEED estimates is needed to deliver outstanding LEED performance levels and a 10 year stream of carbon credits.
A campus laboratory similarly discovered that its design could enable it to be eligible for Chevrolet funding by achieving more than a 20% improvement in EUI within a single year, under the EB-A route. With design specs for the building indicating a 25% improvement was likely, this translated into credits of 990 CO2 tons per year. Again taken over a 10 year period at $5-10/ton CO2, this offered a potential 15-30% return on incremental capital – a significant motivation to ensure that the laboratory would indeed deliver on its fullest potential in practice.
