Optimal indoor air quality
Demand-controlled ventilation limits the intake of fresh
air – and hence the amount of energy – to the amount
currently needed.
This avoids high heat losses caused by improper ventilation
as well as the intake of too much conditioned fresh air in
unused rooms. By preventing rooms from being ventilated
too little or too much, demand-controlled ventilation offers
a pleasant and healthy room climate with a minimum of
stale air and optimal humidity levels.
Comfortable temperature control
Demand-controlled heating and cooling significantly reduces
energy costs while providing a comfortable room climate. This
means that rooms are heated or cooled to a comfortable tem-
perature only when they are occupied. The building’s heating
and cooling distribution system only supplies the amount of
energy actually needed in the rooms.
To achieve this, individual room controllers make it easy to
set daily, weekly and seasonal programs based on occupancy
schedules. In addition, presence detectors can control the heat-
ing and cooling requirements of a room based on whether or
not people are present.
