Demand Charges: The Key to Reducing Your Organization`s Electricity Bill Without Reducing Consumption
CFOs and COOs often struggle to fully understand the different energy saving approaches that are being pitched at them on a daily basis. One of the most mysterious is “demand charges“. Translating this bit of utility-speak is important because in some parts of the country, demand charges can account for up to 50 of your utility bill cost. The good news is that even 24/7 operations can ...

How to tap the energy savings in greywater
Many operators of offices, hospitals, hotels, large condos, and other buildings are aware of the need to save money and reduce their environmental impact, through better water management. The result has been the growth of ways to reduce water consumption, ranging from low-flow show-crheads to landscaping that requires minimal watering. Building operators are also aware of a similar need to ...

Does Innovation in Indoor Air Quality Involve a Paradigm Shift?
Instead of diluting indoor air with compromised outside air, consider removal and destruction of pollutants as part of the HVAC system. Purifying indoor air reduces the level of ventilation required, thereby lessening the energy used to condition outside air. This results in energy savings, increased building value and improved occupant productivity through enhanced indoor air ...

Energy Star failings: Much ado about something
As suspected, Energy Star appliances do not always live up to their energy savings claims, according to preliminary results of laboratory tests reported his week by the US Department of Energy (DOE). The DOE began testing the appliances after watchdogs raised serious questions about the federal labeling program. The Energy Star seal appears on hundreds of models of refrigerators, air ...

The Challange of Cleaning Multi-row Commercial Coils!
The Problem: Over time multi row air conditioning and refrigeration coils (DX, chilled water, etc) can become contaminated and clogged with dirt, debris, grease, seeds, bio-film etc. These neglected multi-row coils drastically increase the HVAC system operating cost. A Pacific Gas & Electric study showed that a dirty condenser coil can increase compressor energy consumption by 30 percent. ...

Ozone treatment for cooling towers
Abstract The use of ozone as a maintenance treatment for cooling towers has good potential for operation and maintenance savings in the Federal secior. A small amount of ozone acts as a powerful biocide thai decreases or nearly eliminates the need to remove quantities of water from the cooling tower in order to decrease the concentration of organic and mineral solids in the system. Ozone ...

UVC lights keep hospital cool, efficient - Rio Grande regional hospital projects annual energy savings of $500,000
The rapidly rising cost of air conditioning energy is a problem for hospitals everywhere, and McAllen, Texas, is no exception. In a town where over 90˚F days are common yearround, and the mercury can top the 100˚ mark even in winter, the seasons might be described as “hot and hotter.” But at McAllen’s Rio Grande Regional Hospital, administrators are staying cool with ...

Rare earth magnets' development
While using NdFeB (i.e. neodymium, iron and boron) sintered magnets in motors' production, the most important requirement of magnet is that the thermal demagnetization should never happen. The so-called thermal demagnetization is a kind of irreversible demagnetization; only by re-magnetizing can the initial flux be insured. When a motor is working, the environment temperature and dysprosium ...

UVC: Florida hospital puts HVAC maintenance under a new light
HVAC system downtime during coil cleaning can compromise humidity and temperature control, potentially leading to air quality or comfort problems. Florida Hospital has found that high-output ultraviolet-C lights installed in the AHUs reduce or eliminate coil- cleaning programs — yielding ongoing energy savings, a reduction in HVAC system maintenance, and the elimination of cleaning ...
