Description

FIELD OF THE INVENTION
The present invention relates to a control system arranged to control at least one controllable device associated with a building space for controlling 5 environmental conditions in the building space, and more particularly to a control system according to preamble of claim 1. The present invention further relates to a method for controlling at least one controllable device associated with a building space for controlling environmental conditions in the building space, and more particularly to a method according to preamble of claim 10.
BACKGROUND OF THE INVENTION
Environmental condition properties in building spaces, such as rooms or office spaces, are conventionally controlled one or more controllable devices, such as HVAC (humidity, ventilation, air conditioning) devices and lightning devices. The environmental condition properties may comprise humidity, 15 temperature, carbon dioxide concentration, air pressure oxygen concentration or light intensity or light spectrum. The operation of these controllable devices is usually controlled with a control system comprising a user interface with which the user may set preferred control parameters, such as preferred temperature. The control system further comprises one or more sensors for measuring the 20 environmental condition properties in the building space. Then the operation of the controllable devices is controlled by comparing the measured environmental condition properties and the preferred control parameters. This is conventionally carried out by utilizing a thermostat in the building space.
There are also control systems which are arranged to detect a presence 25 of a person or number of persons in the building space and controlling operation and the environmental condition properties in the building space based on the presence of person or the number of persons in the building space. In this case the controllable devices are simply controlled based on the presence information or number of persons present in the building space.
One disadvantage relating to the prior art is that controlling the operation of the controllable devices and the environmental condition properties is not based on needs or characteristics of objects, persons, animals or plants in the building space. Accordingly, the environmental condition properties of the building space are controlled based on general control principles without taking into 35 account specific needs of the object(s), person(s), animal(s) or plant(s) in the
20185433 prh 11 -05- 2018 building space at specific moment in time.
