Start with our free CEM practice questions, carefully crafted to mirror the domains, phrasing, and difficulty of the real Energy Management exam. Each CEM exam question comes with a detailed rationale that explains not just which answer is correct but why the others fall short. That's how concepts stick. Use the free set to benchmark yourself: identify your AEE weak domains, see where you're losing marks, and build a focused study plan in minutes.
Which of the following statements best describe Demand Control Ventilation (DVC) in Building Automation Systems?
What is the best type of heat exchanger to recover and transfer latent heat energy from one air stream to another?
A cooling tower is delivering water to a chilled-water plant. The cooling tower outlet temperature has a 6°C approach temperature to the ambient air, wet-bulb temperature. The outside air conditions are 20°C dry bulb, 60% relative humidity. Using the psychrometric chart, at what temperature can the cooling tower deliver water to the chilled-water plant?
A concentrating solar thermal system collects 5 GJ/h of thermal heat, which is delivered to a 94% efficient hot water generator. The hot water generator is used to raise the water temperature from 15°C to 65°
C.
The specific heat of water (Cp) is 4.2 kJ/kg-°C.
What flow rate (liter/second) of hot water can be delivered from the hot water generator?An energy project implemented today saves $10,000 per year for the next 20 years. Using the 5% interest table, determine the total value of savings at the end of the 20th year?
