Healthcare organizations spend over $6.5 billion on energy each year and produce 8% of the country’s carbon emissions. Per energystar.gov, hospitals and other healthcare facilities can protect their bottom line by being more energy efficient: every $1 a non-profit healthcare organization saves on energy is equivalent to generating $20 in new revenues for hospitals or $10 for medical offices. For-profit hospitals, medical offices, and nursing homes can raise their earnings per share a penny by reducing energy costs just 5 percent.
Hospitals alone use a tremendous amount of energy psf of building space:
One of the most cost effective energy upgrades is retrofitting inefficient lighting. Lighting accounts for 43% of Healthcare electricity use (U.S. Energy Information Administration); and Healthcare is second only to Food Sales in the use of lighting per sf of floor space:
Per energystar.gov, new LEDs can be up to 40% more efficient than fluorescent bulbs and 90% more efficient than incandescent. Since they run “cool” they don’t heat the ambient air like other bulbs, thus they decrease the load on cooling systems. Unfortunately the overwhelming majority of Health Care lighting is still fluorescent, making the industry 4th in use of this outdated technology. Some hospitals have thousands of fluorescent lights making them prime candidates for energy upgrades.
Despite LEDs’ substantial energy savings over time, many healthcare facilities have been hesitant to upgrade because of high upfront costs. Additionally, swapping out bulbs over time is not an option due to the variable lighting characteristics of the different bulb types; their colors and intensities clash.
UAPG allows healthcare facilities to upgrade to energy efficient lighting systems painlessly with no upfront cost and little to no effect on budgets.
Variable-frequency drives (VFDs) are systems used to control motor speed and torque. These drives provide precise electrical motor control so that motor speeds can be ramped up and down utilizing only the energy required, rather than having a motor run at an inefficient constant speed regardless of demand.
The main function of a VFD is to affect a reduction in energy usage. The U.S. Environmental Protection Agency estimates that installing VFDs can result in 52 percent average annual energy savings. Since the horsepower required to run a fan or pump is a multiple of its motor speed, an overall 20% reduction in speed can yield energy savings of 50%. Additionally, maintenance costs can be reduced since lower operating speeds result in longer life for components.
Options for VFDs include:
Hospitals operate around the clock, making them good VFD candidates. However, variable frequency drives are not a good choice for every application.
Our engineering partners can determine where VFD installation will be most effective, and do so with no upfront costs to you.
