Electricity Management

http://machenergy.com/solutions

MACH collects interval data from your building's utility electric meters on a daily basis. We also collect historical usage data direct from your utility company, typically 2 years back in time. Our on-demand software then allows authorized users to.

* Consolidate and organize all of your company's electricity expense information in one place - across all utility jurisdictions. No more need to key-in and try to compare electricity usage and cost numbers from differently formatted utility bills or deal with differing bill cycles.
* Easily create online electricity budgets taking into account temperature, occupancy and electric rate escalation.
* Run variance reports of actual vs. budget - by building and by portfolio.
* Identify and prioritize savings opportunities and measure progress toward savings targets with management level, portfolio performance reporting.
* Fine tune building operations using MACH's Expected Operating Envelope™ technology to normalize building operations for temperature and get a true measure of savings.
* Quickly respond to deviations from normal operations with automated alerting based on the MACH Expected Operating Envelope technology.
