CALGreen Requirements for Energy Monitoring
With CA’s approval of a Green Building Standards Code dubbed “CALGreen,” it became the first state in the nation to enact a mandatory green building law. While the debate has just begun on CALGreen’s implications, savvy energy management professionals know that they need to get out in front of the new regulations.
A key CALGreen requirement – similar to USGBC’s LEED-EB regime – is the need for persistent Energy Monitoring.
Agilewaves provides virtual submetering via sensor measurements and a long-term data storage capability to satisfy these Energy Monitoring requirements. In fact, Agilewaves goes beyond the hourly reporting requirements to facilitate advanced trend logging and analysis based on 1 minute intervals. By providing real-time actionable information on all building systems, Agilewaves also allows building owners to trim costs and reduce environmental impacts of day-to-day operations.
CALgreen Section 504.2
504.2 Energy monitoring. Provide submetering or equivalent combinations of sensor measurements and thermodynamic calculations, if appropriate, to record energy use data for each major energy system in the building.
504.2 Energy monitoring. Provide submetering or equivalent combinations of sensor measurements and thermodynamic calculations, if appropriate, to record energy use data for each major energy system in the building, including chillers, heat pumps, packaged AC systems, fans, pumps, cooling towers, boilers and other heating systems, lighting systems and process loads. This energy use data, once collected, shall be stored within a data management system.
504.2.1 Data storage. The data management system must be capable of electronically storing energy data and creating user reports showing hourly, daily, monthly and annual energy consumption for each major energy system. Hourly data shall be retained a minimum of 30 days, daily data shall be retained a minimum of 6 months and monthly data shall be retained a minimum of 2 years.
504.2.2 Data access. Hourly energy use data shall be accessible through a central data management system and must be available daily.
