(a)  In general.- A project qualifies as a solar energy project if it: 

(1) is an addition, alteration, or improvement to a commercial building or industrial building; and 

(2) is designed to reduce the energy requirements of the building by using: 

(i) wind energy; 

(ii) energy from a wood-burning appliance; or 

(iii) solar energy of: 

1. the active type based on mechanically forced energy transfer; 

2. the passive type based on convective, conductive, or radiant energy transfer; or 

3. a combination of these types. 

(b)  Examples.- A solar energy project may include: 

(1) a solar process heat device; 

(2) a solar electric device; and 

(3) an earth-sheltered building in which the sheltering substantially reduces the consumption of energy by the building.
