Eastman Chemical Company
) has entered into a collaboration with energy-efficiency and
sustainability engineering firm Green Generation Solutions (GGS)
and Hyatt Regency Houston, part of the
Hyatt Hotels Corporation
), to measure the accurate energy-savings impact of EnerLogic 35
low-e window film.
Hyatt Regency Houston is aiming to address temperature-related
complaints from guests in its 924,000-square foot hotel banking
on Eastman Chemical's window film. Hyatt is also keen to cut its
high energy expenditures that amounted $1.6 million annually.
EnerLogic 35 low-e window film improves the insulation of the
window and also keeps the heat inside the room during winter,
Most other solar films that blocks solar energy from entering a
building in the summer, but they do very little to keep the cold
out in the winter. This unique feature of EnerLogic helps in
yearly savings and improves occupant comfort.
GGS engineers have also installed an extensive sub-metering
system at the time of window film installation at Hyatt to
monitor energy use in 96 rooms (48 rooms with window film, and 48
rooms without window film).
The comparative sub-meter data revealed that rooms with window
films enjoyed a 23% reduction in cooling energy use and 25% in
heating energy. Based on the national average installation costs
and the energy efficiency rebate provided by the local utility,
it has been calculated that these energy savings provided a
payback on the hotel's investment in 3.6 years, or an ROI of 28%
