The greatest energy savings in ventilation is often gained with demand-controlled operation.<\/strong><\/p>\n\n\n\n

The energy consumed by ventilation falls down to less than half when the power of ventilation is reduced by the same amount. When the rooms are empty, the need for ventilation decreases significantly and it is sensible to decrease ventilation.<\/p>\n\n\n\n

Changing working environment – changing needs<\/h2>\n\n\n\n

The length of a working day used to be standard. Everybody was at work from eight to four and the need was at its greatest then. Nowadays, however, the rooms are more varied and work is more mobile. Offices may be empty for long periods of time as the employees work remotely, visit their customers or sit at meetings. The quality of air in a meeting room full of people can be lousy, whereas ventilation is at full power in the offices, consuming energy unnecessarily.<\/p>\n\n\n\n

Decentralised ventilation and carbon dioxide sensors create automatic room-specific ventilation. The sensors measure the quality of indoor air and boost ventilation when needed. This ensures that air in the meeting room stays fresh and the participants stay awake, while ventilation in the empty rooms decreases, keeping energy consumption in control.<\/p>\n\n\n <\/div>\n<\/div>\n\n\n

\n Occupancy-Based Ventilation in Workplaces\n <\/h2>\n
\n \n

The ventilation requirements of commercial buildings vary continuously according to how the spaces are used. Vallox Pureo air handling units provide a flexible solution by enabling ventilation to be controlled based on actual demand, in other words according to occupancy levels. Vallox Pureo air handling units are designed for a wide range of commercial applications, including offices, retail premises, industrial and warehouse buildings, as well as public facilities such as schools and daycare centres. In these types of buildings, ventilation requirements can vary significantly depending on occupancy, highlighting the importance of demand-based control.<\/p>\n\n <\/span>\n <\/div>\n <\/div>\n\n
