Setpoint Refinement<\/b><\/h3>\n
Review your current BMS temperature settings (known as setpoints) and modes to ensure they accommodate changing levels of occupancy at different times of the day.\u00a0<\/span><\/p>\nIt may be possible to adjust setpoints a degree or two up or down to reduce the amount of time equipment runs without sacrificing any noticeable building user comfort. You can achieve a 1% reduction in energy usage for every 1degC change of your hot water setpoint. This can save up to 5% in energy costs (always ensuring you maintain your legionella requirements).\u00a0<\/span><\/p>\nIf your ventilation plant can be speed controlled, then it may be possible to reduce the speed of your fans when occupation in the building is low using a CO2 or occupancy density sensors. The building ventilation will have been designed to cope with peak demand so a reduction in ventilation when your building is quieter will have no adverse effect on comfort.\u00a0<\/span><\/p>\nIf your building does not have individual room or zone control, consider upgrading or replacing with a system that features temperature setpoint control. In occupied areas, providing individuals control over their environment (temperature, fan speed, lighting, etc.) may help with overall satisfaction and, potentially, productivity.<\/p>\n
\n
Night and unoccupied setback<\/b><\/h3>\n
Reviewing current BMS setpoints for out of hours operation is another way to control energy use and costs. You could achieve 8 \u2013 10% in energy savings while still protecting the building in extreme cold or hot weather.\u00a0<\/span><\/p>\nTypical setbacks are 12degC, at which some plant should be started to prevent mould issues and to stay within the ASHRAE recommended range.\u00a0<\/span><\/p>\n\n
Free cooling<\/b><\/h3>\n
Some ventilation systems can be programmed to use the cooler night air to cool down the building without using your chiller plant. This can be especially useful in the summer months.\u00a0<\/span><\/p>\n\n
Optimum start\/stop<\/b><\/h3>\n
An optimal start routine adjusts your equipment start times automatically based on the building\u2019s profile and demand. Starting equipment only when necessary ensures comfort levels for building occupation, while gaining energy savings. Many modern BMS\u2019s can provide this \u2018optimal start\u2019 function, although often the program is disabled or needs modification to work correctly.<\/p>\n
\n
Useful alarming<\/b><\/h3>\n
Often, a BMS that has been set-up poorly will generate hundreds of nuisance alarms. As a result, building users stop interacting with it. This is counterproductive. Alarms can be a useful tool in managing the building and its energy use. A well thought-out alarming scheme should have tiers for critical, non-critical and maintenance alarms.\u00a0<\/span><\/p>\n\n
Other considerations<\/b><\/h3>\n
\u2022 Check fan and pump speeds are not being operated at higher speeds than required. It may be possible to set them up to vary their speed with demand.<\/p>\n
\u2022 Make sure heating and cooling setpoints don\u2019t overlap. The settings of adjacent heating and cooling devices are frequently found to overlap, resulting in both heating or cooling at full capacity (which also creates discomfort). Avoid this by adjusting temperature settings to ensure there is at least a 2degC \u2018gap\u2019 in which neither heating or cooling is taking place (e.g. heat up to 21degC, cool down to 24degC, with no heating or cooling in between).<\/p>\n
\u2022 Make sure air isn\u2019t heated, then cooled back down again. Check that air handling units that supply air into offices are not set up so that they heat up cool outside air, only for that air to be cooled back down by cooling units in the office space. These air handling units can usually be set up so the air supply temperature responds to the heating or cooling demand of the building.<\/p>\n
\u2022 Check over your control panels to see if any of the switches are set to the manual or \u201chand\u201d symbol. If so, that item will run continuously 24\/7.\u00a0 <\/span>If the system won\u2019t run on \u201cauto\u201d there may be an issue that needs resolving. Automatic control will always save energy.<\/p>\n\u2022 Most modern BMS systems are capable of open communication with systems from other vendors. This means you can get competing prices for new installations from a few different vendors. \u00a0<\/span><\/p>\nThese are just a few examples. There are many options and variations that can be used to make the building easier to operate, and to reduce energy use. A conversation with a BMS contractor outlining how you use the building will allow them to create an interface that best suits your situation.<\/p>\n
