Consulting-Specifying Engineer Top 5 most read articles online, for Aug. 3-9, covered cogeneration systems, LED codes and standards, efficient hot water systems, data center PUE and efficiency, and IAQ in hospitals. Link to each article below.

1. Understanding cogeneration systems

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.

2. Your questions answered: LED codes and standards

In lighting, one size/type does not fit all. LEDs, or light-emitting diodes, have gained prominence in lighting design for their energy and operational savings. More information is provided by the presenters of the July 23 webcast.

3. Efficient hot water systems

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.

4. Driving data center PUE, efficiency

When developing data center energy-use estimations, engineers must account for all sources of energy use in the facility.

5. Indoor air quality in hospitals

Hospitals and health care facilities must comply with ASHRAE and other regulatory standards with respect to air change rates, humidity requirements, and pressurization. ASHRAE Standard 62.1 is the most commonly referenced standard to meet appropriate HVAC system design.

The list was developed using CFE Media’s web analytics for stories viewed on csemag.com, August 3-9, for articles published within the last two months.
