1. LED renovations and retrofits: Evaluating codes and costs
Clients are asking lighting designers to help them save on energy costs, and replacing fluorescent, HID, or other lights with LEDs is in high demand. Here’s a look at the codes and guidelines that define LED use, including ASHRAE Standard 90.1, California Title 24, Dept. of Energy, and IECC.
2. Driving data center PUE, efficiency
When developing data center energy-use estimations, engineers must account for all sources of energy use in the facility.
Cogeneration systems-also known as combined heat and power (CHP) systems-generate both electricity and usable thermal energy. These systems typically are used on campuses that have high heat load requirements.
Engineers should work to design the most efficient water heating system or boiler possible. Understanding the codes/standards is paramount, followed by knowledge of the key equipment functions of boilers and similar systems.
NFPA 99-2015 establishes criteria for levels of health care services or systems based on risk to patients, staff, or visitors in health care facilities to minimize the hazards of fire, explosion, and electricity. Here’s what’s in the current code and what engineers need to know once their authorities having jurisdiction enforce this version.
