What process uses heat recovery to capture heat from the process of generating electricity and then turns the recovered heat into thermal energy that can be used to heat a building?
A: Commissioning
B: Evopotranspiration
C: Cogeneration
D: Tertiary treatment

参考答案: C

本题解释:
Commissioning is systematic process of assuring that a building performs in accordance with the design intent and the owner\'s operational needs.
Evopotranspiration is water leaving plants and soil and returning back to the atmosphere.
Combined heat and power (CHP) is an electricity generation technology, also known as cogeneration, that recovers waste heat from the electric generation process to produce simultaneously other forms of useful energy, such as usable heat or steam. On average, two-thirds of the input energy used to make electricity is lost as waste heat. In contrast, CHP systems are capable of converting more than 70 percent of the fuel into usable energy.

A project that treats 50% of wastewater onsite to tertiary standards can earn the Innovative Wastewater Technologies credit. Tertiary treatment of wastewater leaves the water in a state where it can be used for agriculture or discharged back into the environment. It is not suitable for drinking;
