The Elimination of Waste
Implementing an energy management strategy is not as easy as purchasing. product and fitting it to a building or site. The opportunities for thrift are endless and can be realised over a period of time through a series of energy audits. The EnergyHub speeds this processing up by delivering the low hanging fruit of energy management through a series of sophisticated algorithms that are based on the principle of LEAN. To gain an understanding of how HUB Automation's energy management algorithms operate and how they are interconnected wth energy use and comfort for each application a consultation is required. Below is a short description to provide a base point for developing an energy management strategy.

Occupancy Setback |
Dynamic Performance Band (DPB) is an adjustable parameter for comfort and lighting management that allows a hierarchy to be set up across thermal and lighting zones for the purpose of discreet load shedding. A scale and an alarm state is set so that has total system load approach a set threshold adjustments can be made zone by zone often without any impact on occupants. DPB can be connected to solar harvest, a nominal threshold or even a dynamic threshold based on tariff value. The set hierarchy can be adjusted by technician and maintenance staff without the need for programming.

Target Drag (DTD) can be attached to comfort and lighting zones so that as the ambient conditions shift the set point can also shift. A typical application of this would be during a heatwave. As the outdoor temperature increased above design conditions the efficiency of the air conditioning systems reduces increasing the impact of the heatwave and dramatically increasing energy use. DTD shifts the comfort target up as the outside ambient temperature increases and by doing so reduces the heat ingress, reduces energy used and protects the air conditioning equipment.

Occupancy setback (DOS) is widely used in hotels. The principle is that when a space is not occupied the comfort target or lighting target can be adjusted to save energy while keeping close enough to the occupied target so that when entered the space quickly recovers to an optimum condition. The key with this type of system is how occupancy is detected, a range of options are available in the EnergyHub including PIR sensors, calendar integration, CO2 monitoring and DB sensing. DOS can be used for lighting, air quality, pools, hot water and thermal comfort.
