MILWAUKEE, Nov. 16, 2012 /PRNewswire/ -- Telkonet, Inc.

In utilizing Telkonet's proprietary hardware and energy management platform, the Hilton Northbrook, the Hilton Lisle/ Naperville, and the DoubleTree Alsip will reduce their energy usage by an inspiring 35%. "Sustainability has become an important criterion for both leisure and business customers when selecting a hotel," said Frank Allgauer, co-owner of the three hotels. "Telkonet's EcoSmart system allows us to be sustainable without impacting the guest experience, which is what many of our travelers want to see. There's an interest in 'going green,' but not at the expense of room comfort." Telkonet's Recovery Time™ technology makes EcoSmart a unique and desirable energy management solution, particularly within the hospitality market. Unlike any other energy management solution, Telkonet's intelligent thermostats save energy when a room is unoccupied without inconveniencing a guest upon his or her return. "There is no fixed setback temperature," said Brandon Husko, Chief Operating Officer of Green to Guest. "EcoSmart's Recovery Time™ calculates dynamic setback temperatures for individual rooms – it's simple, yet sophisticated. I stand behind the technology 100%." To provide additional energy savings, the trio of hotels elected to include Telkonet's "Green Button," a feature that allows guests to opt-in to energy conservation measures. Pushing the button enables modest adjustments to setback temperatures and length of the Recovery Time, enabling guests to be actively eco-friendly.
