Xcel Energy runs trial in Colorado to control energy demand

Ten commercial buildings in Colorado are piloting a smart energy system to reduce energy consumption and help in demand response relief. The trial is being carried out by utility Xcel Energy using energy management software from San Francisco-based BuildingIQ.
The buildings have an average daily summer peak load over 500kW and will use the PEO predictive energy optimisation platform to reduce day-to-day energy consumption and be automatically called upon by Xcel Energy to assist in demand response relief, thus allowing the utility to avoid the need to purchase or produce additional power during periods of high demand.
“Xcel Energy is making its current infrastructure more dynamic while also creating value for its clients with the BuildingIQ platform,” said Michael Nark, CEO of BuildingIQ. “Buildings that have our technology installed will be able to reduce operating costs on a daily basis and participate in demand response events. The cloud-based nature of the platform allows it to be installed quickly and enables users to see results right away, without disruption to a building’s infrastructure or daily activities.”
The software uses predictive analytics to enable intelligent building management. Variables such as occupant comfort, building characteristics, historical data, weather forecasts and utility signals are used to make real-time changes to temperature and airflow to alleviate energy usage when the power grid is constrained. The technology allows users to take control of their energy costs and help improve the environment.
“Xcel Energy is proud to have BuildingIQ as our technology partner for this pilot programme,” said Anne Kraft, pilot manager for Xcel Energy. “BuildingIQ’s PEO platform offers a unique way to combine energy efficiency and demand response in one package and could prove to be a valuable addition to our successful demand side management portfolio in Colorado.”
Measurement and verification are an intrinsic part of the system. All collected data are compared to baseline models and reported savings are consistent with international performance measurement and verification protocols. In addition, through the programme these savings will be examined by a third-party evaluator.
BuildingIQ’s energy management software actively predicts and manages HVAC loads in commercial buildings and claims reductions in HVAC energy costs by up to 25 per cent.
