Building Energy Management System

Savings of 30%+ can be achieved by using FairUsage, so how does it work?

At the heart of the controller is a state-of-the-art microprocessor with 8 temperature sensors, 8 occupancy sensors and 8 mains electricity relays. This can manage and control a block of 8 apartments. The program inside the controller has the following functions:

• Accurately switching on/off electric heater using a heating diary. Heating is not left on during weekends, holidays or planned absences, unless the apartment is being used. For each separate apartment
  • The heating diary can be different.
  • Different set-points at different times of the day – different conditions for different people.
• A “self learning” heat-loss algorithm that works out the heat-loss profile of a particular apartment. This allows the controller to switch the heating on later (and off earlier) on warm days and earlier/later for cold days, automatically adjusting the heating depending on how warm it is outside.
• Automatic occupancy detection allowing the temperature to reduce to a background when the apartment is not used and quickly bringing it up to temperature when people return.
• Gradient control of room temperatures at different times of the day.
• User “heat me now” buttons that revert back so the heating is not left on too high so as to affect behavioural change.
• User “boost” button that degrades back to setpoint slowly so no sudden drop in temperature.
• Night setback temperature, reducing the night heating by a few degrees to still keep 24/7 operations warm whilst saving energy and money. Particularly useful for healthcare installations.
• Electricity usage monitoring from pulse meters to calculate accurate minute-by-minute costings together with kWh’s and CO2 statistics.
• Email/text alerts if:
  • A heater fails
  • Abnormally high temperature (fire?)
  • Abnormally low temperature

The main features of HeatingSave Fair Usage System are:

• Multiple heating/cooling pattern control with an integrated diary function so the heating is not on during weekends or holidays unless the building is being used – saving up to 30%.
• Advanced heat-loss algorithm manages multiple heating/cooling zones applying energy at the last moment or switching off early to minimize energy usage. Automatic outside temperature compensation and climate control – save up to another 10%.
• Gradient control of room temperatures at different times of the day.
• Automatic occupancy detection allowing the temperature to reduce to a background when areas are not used and quickly brought up to temperature when they are being used.
• Night setback temperature, reducing the night heating by a few degrees to still keep 24/7 operations warm whilst saving energy and money.
• Network and web based software using standard large database structures to create a structure of properties and heating systems within your organisation. Multiple graphical and site schematics allow you to manage thousands of buildings, their infrastructure and maintenance.

HeatingSave FairUsage comprises:

• HeatingSave FairUsage Intelligent Controller
• 8 room temperature sensors
• 8 occupancy sensors
• HeatingSave FairUsage PC software
• Installation instructions.
• Additional sub-unit controllers are available to extend your system. These additional networked sub-controllers add 8 analogue, 8 digital inputs and 8 relays at a time to the standard system, to a maximum of 13 sub-controllers per main controller; but millions of controllers can be added to a system. The only limit being a unique Internet IP address.

Organisations that will typically benefit from HeatingSave FairUsage will be multi-sited private and public sector facilities including university halls and housing, social housing, hotels/inns/motels, sheltered housing, hospitals, infirmaries, hostels and boarding apartments, care homes and healthcare centres.
