A project pursuing LEED BD+C certification is designed with an electric air-source heat pump as the primary heating system to meet EAp1: Operational Carbon Projection and Decarbonization Plan. However, the client is considering adding a small natural-gas boiler for backup heating during extreme weather.
To earn maximum points under EAp1 while maintaining heating-system reliability, what should the LEED AP recommend regarding supplemental heating?

• A.Design an all-electric supplemental heating system using electric-resistance elements or auxiliary heat-pump capacity to eliminate on-site fossil-fuel combustion
• B.Install a natural-gas boiler with automated controls that limit operation to extreme conditions and include provisions for future conversion to an all-electric system
• C.Implement a wood-pellet biomass boiler as secondary heating because it qualifies as carbon-neutral without penalizing on-site combustion
