These conditions were noted in an energy audit report: “The fire/smoke damper was closed.” “The coils are still dirty.” These are not unusual examples. Since 40 percent of the energy used in the United States is used to operate buildings, it is obvious that a big step in making America green is to make our buildings green.
What’s the fastest growing sector of the green building movement? According to consultant Jerry Yudelson, not the usual architectural highlights of zero energy buildings, but the more prosaic existing building upgrades profiled in his latest green building book, Greening Existing Buildings. Building upgrades are being seen throughout the U.S. and Canada.
As an HVAC contractor, you have an opportunity to help educate your customers. With the amount of environmental pollutants we’re exposed to every day, it’s crucial for us to ensure we’re providing our customers with not only high-performing products in their homes, but also healthier indoor environments.

The Frito-Lay plant in Killingly, Conn., has installed a combined heat and power (CHP) system designed to help remove it from the Northeast power grid. Located in a region with severe electrical transmission constraints, Frito-Lay saw CHP as a potential opportunity for achieving near-term energy efficiency improvements and reducing emissions.
The U.S. Department of Energy (DOE) notes that industrial buildings employ energy-intensive systems to heat, ventilate, air condition, light, and otherwise support processes and personnel. These industrial facilities present a unique opportunity to save energy by recovering energy and/or water from industrial processes.
The convenience of rooftop packaged units has driven a demand for increasingly larger units. With these larger units, many factors need to be considered in the design of the building, such as increased structural support. Unfortunately, the increased sound levels produced by these units are sometimes overlooked.
