A project team is working on a mixed-use development aiming to achieve LEED certification.

LEED v5 EAc1: Electrification is intended to reduce dependence on on-site fuel combustion and enable lower-carbon building operation. Solar thermal water heating can reduce or displace combustion-based service-water-heating demand. LEED ' s electrification framework specifically recognizes solar contribution when evaluating service water heating, including a qualifying domestic-hot-water solar fraction under the applicable pathway. A high-efficiency gas boiler remains combustion equipment and therefore conflicts directly with the objective of reducing on-site fossil-fuel use. Electric-vehicle charging supports transportation electrification but does not reduce combustion from the building ' s space-heating or service-water-heating systems. Of the choices provided, a solar thermal system is therefore the only measure that directly reduces the building ' s reliance on combustion for a significant thermal load and supports the stated decarbonization objective.
