Energy Efficiency with Building Automation Systems II

Welcome to energy efficiency with building automation systems part two. This is the second course in a two-part series on this topic if you have not already done so please participate in energy efficiency with building automation systems part 1 before taking this course.

At completion of this course you will be able to recognize the benefits of a building automation system and identify common energy conservation measures for lighting, HVAC boilers and water heaters and maintenance. A building automation system also referred to as a BAS can be set up to automate a building to make work more efficient for facility managers and more effective for occupants.

An energy management system is a subset of that in that while it performs like a building automation system it also focuses to automate the building to run as energy efficiently as possible.

Building automation system can improve maintenance efficiency by providing the maintenance schedule and optimizing. It based on the running time of equipment or other physical parameters this allows implementation of condition based maintenance rather than scheduled based maintenance.

The result is that equipment that needs maintenance sooner gets attention when required helping maintain equipment efficiency and prolonging its life equipment that has been little used and does not need maintenance can be deferred ensuring that maintenance effort is used where it is most needed for instance a filter may have to be checked once a month just to make sure a change out was not needed however now pressure sensors could detect when a filter was restricting too much flow and needs a change out when those pressure sensors fall below a critical level.  

An alarm could alert maintenance staff to make a change instead of a guess and check scheduling method let’s take a moment to review what we have covered throughout this course.

There are a number of different strategies we have discussed which can be used to reduce energy consumption they include air side focused strategies including warm-up cool down ventilation and recirculation.  Use of economizers night ventilation purge static pressure resets supply air resets hot cold deck temperature resets and reheat coil resets.

We also discussed chilled water side focused strategies including chilled water reset condenser reset and chiller sequencing additionally. We talked about hot water boiler side focused strategies including boiler staging hot water reset domestic hot water control and remote boiler monitoring and supervision and we discussed controls implemented strategies including scheduled start/stop lighting controls, unoccupied setback start/stop optimization, demand control ventilation, demand limiting heating cooling equipment, lockout duty cycling and maintenance and management using these. Energy conservation measures will result in increased energy savings to any Facility.
