Does it take an entirely new HVAC system to save big money on energy costs in a commercial high-rise? Maybe not. At a 17-story Dallas office tower, an energy-efficient HVAC retrofit and energy management system are apparently doing the trick.
Incenergy said that in the first four months after installation, its Smart Building EMS solution trimmed energy usage at the Highland Park Place building by 262,736 kilowatt-hours compared to the previous year. That equals an electricity savings of $5,800 per month. The company said it developed the HVAC retrofit system initially for use in low-rise commercial buildings, then scaled the technology for use in a larger high-rise building.
The technology uses wireless and cloud computing compatible with smart thermostats. The platform also supports mobile devices running iPhone and Android for tracking and reporting purposes. Along with a 20 percent efficiency gain, the building’s carbon dioxide emissions are expected to be cut by as much as 1.2 mllion pounds of CO2 in the first year, Incenergy said.
The company said the reductions come from the automation and schedule optimization of temperature set-points, temperature override limits and fault detection alerts. Commercial buildings are said to be responsible for more than 40 percent of the world’s energy use and carbon emissions.
