College’s Energy Forecasting System to ‘Reduce Energy Demand 7-10%’

January 17, 2013 By Jessica Lyons Hardcastle

Edmonds Community College in Lynnwood, Wash., has installed an energy forecasting service that GridNavigator and ATS Automation say will add 3-5 percent savings and reduce energy demand by 7-10 percent across the more than 30 facilities on the 50-acre campus.

According to the companies, the service forecasts intraday energy demand to optimize existing building management systems without significant additional capital outlays.

The long-term partnership between the three organizations began in 2009.

The most recent energy management system designed by ATS Automation for Edmonds Community College uses GridNavigator, which provides ESCOs and building engineers with accurate predictions of energy demand, based on advanced quantitative analysis models originally developed for the financial services industry.

A GridNavigator BACnetXchange server, installed at the facility, gathers energy data in real-time from an Alerton BMS and delivers it to the GridNavigator cloud-based energy forecasting service for analysis. Building optimization routines are then delivered from the GridNavigator cloud-based service directly to the Alerton BMS every hour. The companies say this system improves upon existing systems that rely upon historical building data.

The GridNavigator BACnetXchange server integrates with existing building management systems and communicates with energy endpoints using multiple industry-standard protocols.

BACnetXchange is a combination of a technology stack combined with communication drivers for a variety of vendors including Alerton, Honeywell, Johnson Controls and Siemens. The cloud-based algorithmic data engine provides energy and demand usage forecast with 97.5 percent accuracy.

According to Pike Research, the market for smart building management systems (SBMS), which includes data acquisition and analytics, as well as building maintenance contracts, is growing rapidly and is expected to reach more than $1 billion worldwide by 2020.

The broader energy management systems market is predicted by Pike to reach annual revenues of $6.8 billion in the US by 2020.
