Finding HVAC Religion In 2010, the Eastside Christian Church purchased a former Boeing Defense Systems site in Anaheim, Calif. and began an extensive renovation project, which was completed in 2012.

ZONE CONTROL The SmartME Zone Controller can control up to 16 indoor units in a single zone, and features a backlit touchscreen interface with dual set-point functionality and LED color status indicator. The advanced control and monitoring functions include temperature and humidity sensors, and an Energy Save setting, which designated operation using occupancy and brightness sensors.

A core element to support renovation goals would be the HVAC systems chosen to heat and cool the various areas of the new campus, encompassing approximately 100,000 sq. ft. of classroom, office and worship space in the first phase of development. The project team was seeking a system that could easily control temperature in select areas “on demand” without wasting energy and expense heating or cooling areas not in use.

Fault detection and diagnostics is also an area that will continue to gain traction. Owners and facility managers can now use data to proactively identify performance concerns that may lead to wasted energy use or premature equipment failure. Different from alarms, fault detection and diagnostics is future looking and tries to anticipate issues before they create true problems for a facility.
“Concepts of analytics and fault detection have long been an integral part of the tools provided by most building automation systems. Alarms, reports, trends, summary graphics, dashboards—these are all means of discovering and communicating ‘meaningful patterns in data,’ which is the primary function of analytics,” says Tom.
BAS Security Even as the user interface is expanding to include a much wider audience, concerns over security are increasing, cautions Tom. A few years ago the focus was on preventing hackers from using the BAS as a “back door” to access other IT systems. 60
It was decided that a variable refrigerant flow (VRF) system could provide custom temperature control in specific rooms and areas; heating or cooling selected spaces based on use, while also contributing to significant cost savings on utility bills. LG’s Multi V II Heat Pump System offers the most cost-effective solution to meet both operational and functional needs. The LG system was installed to provide custom temperature control in various offices, video control rooms and sensitive equipment rooms, thus reducing the overall energy consumption for the campus.
