Combined heat and power (CHP), also known as cogeneration, is the simultaneous production of electricity and heat from a single fuel source, such as: natural gas, biomass, biogas, coal, waste heat, or oil. CHP is not a single technology, but an integrated energy system that can be modified depending upon the needs of the end user.
If you remember the rolling blackouts suffered by Californians in the years 2000 and 2001, you may also remember that they cost companies in excess of $50 billion in lost manufacturing capacity and sales. What you may not remember is the good that came out of that disaster.
Boiler efficiency is an important factor in selecting a space heating boiler, but what does “boiler efficiency” really mean? In selecting the right boiler for a commercial application, it is important to understand the difference between the various types of boiler efficiencies.
Focusing on only one can come at the cost of the other

The National Institute of Standards and Technology (NIST) says you can breathe easy in its net-zero energy house. After 15 months of monitoring, researchers report that even with its airtight construction, IAQ in the two-story home that serves as a laboratory is better than the IAQ in new, conventionally built houses.
The so-called “thermostat wars” in office buildings have been written about in both the consumer and trade media. Some in the office say it’s too hot. Others say it’s too cold. Building operators, and their HVAC contractors, try to find a satisfactory solution, but it’s elusive, as shown in a study by Software Advice.
Waste Management is seeing about a 100 kWh drop in monthly power utilization

Data centers continue to evolve and become more efficient. The need for efficient HVAC is essential to ensure cost-effective, reliable operation given servers generate significant amounts of heat. As part of a facility upgrade, Waste Management replaced its chiller plants to serve its production data center facility in Austin, Texas.
Falls from portable ladders (step, straight, combination, and extension) are one of the leading causes of occupational injuries and fatalities. The following are some quick tips from the Occupational Safety and Health Administration (OSHA) on ladder safety.

A Netherlands-based consortium called Energiesprong brokered a deal between affordable housing associations and builders to retrofit 111,000 homes in the Netherlands to net zero energy levels. Net zero energy means that, on an annual basis, a home does not consume more energy than it produces.
In October 2009, Stanford University released a comprehensive and long-range Energy and Climate Action plan aimed at maximizing energy efficiency and utilizing clean, renewable energy on campus. The plan includes a cutting-edge energy supply system known as the Stanford Energy System Innovations (SESI) project.
On a recent call to replace an aging gas boiler, the owners reported a persistent gas smell. The gas company had previously inspected the building and couldn’t find a leak. Yet the smell continued. The point is, if you smell gas, however subtle the smell, there is a gas leak. Somewhere. The challenge can indeed be where to find it.
