Measuring temperature, humidity, occupancy, and CO2 levels can help to observe and create improved air quality that is essential for occupants/employees’ well-being and

productivity.

​

Supplying fresh air to a floor plate is an expensive exercise. The fans consume electricity to extract air and supply fresh air, which is then either heated or cooled via hot or cold water supplied by pumps from the boilers and chillers.

 

Rather than supplying a constant amount of air, CO2 sensors are often used to measure the actual demand. When fewer people are present or the air quality isalready optimal, the AHU reduces the ventilation rate, thereby saving energy.

​

Conversely, when occupancy increases or air quality deteriorates, the ventilation rate is ramped up to ensure a healthy and comfortable indoor environment.

 

This approach not only promotes energy efficiency but also ensures that indoor air quality is maintained at optimal levels.

 

Most modern buildings will already have a certain amount of space temperature sensors and if the sensors are providing data to the BMS, Optimise Everything will be able to use this data to optimise the performance of the building.

 

However, we often find that the quantity and location of these sensors is not optimal or in fact they arefaulty.

 

OE Air Quality Sensors are wireless and battery operated and therefore is easy to install and measure temperature, air quality, lux and humidity and communicates this information to Optimise Everything Gateway every 15 minutes.

 

This critical data is then displayed on Scope and/or can be fed back to the BMS to ensure optimum performance.

​

Monitoring CO2 levels is a valid method for estimating occupancy in real time, thereby enabling demand-controlled ventilation to maintain air quality with reduced energy consumption while balancing health, user comfort, and energy efficiency.

 

Occupants will immediately benefit from having Air Quality Sensors ensuring that occupants experience the ideal working environment with the desired amount of fresh air being conditioned for the space, avoiding unnecessary running of equipment.

 

A future intervention to avoid conditioning unoccupied spaces would be to integrate the sensors into the BMS for dynamic control.

 

OE Air Quality Sensors will provide critical data to ensure that floors are at comfortable set points following a set of rules. For example, we want to avoid employees

complaining of being too cold due to floors not reaching set point.

​

The net benefit is two fold, improved air quality at busy times leading to workforce productivity gains and cost reductions during quieter times.
