b. Those that generate more energy than they utilize
c. Those that use only clean and green energy
d. Both b and c
Answer  Explanation 

ANSWER: Those that generate as much energy as they use

Explanation:

  • Net Zero Energy Buildings are those that generate as much energy as they use.
  • Net or nearly zero energy buildings (NZEB) are highly efficient buildings with extremely low energy demand, which is met by renewable energy sources. Such buildings produce as much energy as they consume, accounted for annually.
  • In order to achieve their net zero energy goals, NZEBs must first sharply reduce energy demand using energy efficient technologies, and then utilize renewable energy sources (RES) to meet the residual demand.
