Coil “Crime Scene” Investigation
Operational forensics is the practice of using building automation system data and data analytics to determine the sequence of events leading up to an incident and to determine root cause. The Executive Overview Imagine walking into your facility on a Monday morning to find water covering the floor. Water damage is everywhere – mechanical rooms, […]
2018 International Green Construction Code Released
Groundbreaking model for building codes helps municipalities save money, protect resources and increase the resilience, safety and standards of living for communities across the globe WASHINGTON, D.C. – (Nov. 8, 2018) – The 2018 International Green Construction Code (2018-IgCC) was released today by the U.S. Green Building Council (USGBC), International Code Council, ASHRAE and the Illuminating Engineering Society (IES). The IgCC is […]
Fume Hood Face Velocity & Airflow
Cimetrics identified fume hoods that have face velocities greater than the high limit threshold of 100fpm, which result in excess energy use, as well as face velocities below the low limit threshold of 80 fpm, which have safety implications.
Cimetrics Senior Analysts presentation at the 2018 I2SL Annual Conference
Our Senior Analysts – Lisa Zagura and Julianne Rhoads presented: “BE A BTU HUNTER: How Big Data Analytics Can Achieve Energy and OM Savings While Improving Productivity, Comfort, and Sustainability at Laboratory Facilities”.
Simultaneous Heating & Cooling
The Air Handling Unit (AHU) preheat coil valve was leaking when signaled closed (0% valve signal), resulting in a preheat discharge temperature that was over 40 degrees warmer than the required temperature. As a result, the cooling coil valve opened simultaneously to maintain the final supply air temperature at its setpoint of 55°F. The simultaneous heating and cooling resulted in excess heating […]
