Because of their unique requirements for lighting, ventilation, and equipment, laboratory buildings use a considerable amount of energy. The reliability of that energy is very important. Laboratories must be able to conduct research without power interruptions, which can damage both equipment and experiments. Generating power and heat on site is one good way to enhance reliability; it can also improve fuel utilization while trimming utility costs.
When should laboratory managers consider on-site power generation or combined heat and power systems for their facilities? Some answers to that question are in the guidelines and “rules of thumb” presented here. Actual costs and benefits for a particular facility can be determined through a detailed feasibility study
