With another AHR Expo in the books, it’s clear that even though the industry is gradually progressing, overall it’s ripe for innovation. Four areas in particular stand out where forward-thinking manufacturers can have a powerful impact.
What causes poor IAQ? What are the negative effects? And most importantly, what can be done to achieve cleaner indoor air? This article will attempt to shed light on these questions so we can all breathe a little easier.
Contractors, architects, engineers, and others who specify commercial and industrial boilers continually seek systems that are more cost effective, energy efficient, and environmentally friendly. The boiler industry has responded by making significant advances in both construction and design.
The new Building Load Deferment (BLD) system, from HIGHMARK, New York City, is a pre-engineered thermal energy storage system, enabling energy usage to be deferred to off-peak hours via ice storage and then utilizing that ice for the building’s chilled water system during peak hours, for energy savings of up to 50 percent.
Localized comfort could bring big HVAC energy savings
December 7, 2015
Tucked inside a unique structure at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL), two volunteers were participating in an experiment inside NREL’s newly constructed Comfort Suite (C-Suite) designed to reveal the connection between human comfort and energy systems.
Challenging application required a custom solution
November 23, 2015
For the inhabitants of a five-story building in New York City, the heating and cooling system had surpassed the point of discomfort. After an extensive remodel and update of the building, the one detail that had been left untouched was the control integration of the HVAC system.
Selling end-users just an energy recovery ventilator (ERV) without realizing the options or wheel’s long-term performance benefits cheats a facility out its full energy-saving potential, which is ironically the premise for energy recovery in the first place.
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.
