Room automation means the integral automation of all technical equipment used for heating, ventilating, cooling, lighting and sun-screening rooms, which can be installed not just in new buildings but within existing building structures.


It is thus much more than the individual room control we know from HVAC technology, as it also comprises electro-technical systems such as lighting control and sunblind control. These are embedded in a coordinated, integrated system in which each measurement value is recorded just once and supplied to all control devices, and in which all operating and control functions are harmonized to provide optimal energy efficiency and a high level of comfort.

Using a whole bundle of partial functions, room automation automatically reduces heating, cooling or electrical power requirements as a function of the room utilization and the free energy sources available, such as sunlight or cool night air, to a minimum. In this way energy and cost savings of up to 50% can be made.


The technical demands made particularly on commercial buildings are increasing all the time. The reasons for this are found in the ever-increasing energy costs, in the realisation that an ergonomic working environment is an essential contributory factor in the efficiency and productivity of the users, and finally in the continually changing working practices, which always require an adaptation in the way the surface area is divided.

In summary, what is needed of a building or property is


more energy efficiency
more productivity
more flexibility

What all these demands have in common is that they can only be met in situ, in places where the building and user are in direct contact, i.e. in the rooms. This is where room automation comes into play, breaking away from traditional ideas regarding the separation of systems which hitherto made achieving these goals difficult.

Only an integrated system without gateways and communication barriers between the individual functions can solve the tasks in question in an economical manner. This is why room automation is the key tofuture-oriented buildings.


Energy performance

The European Directive on Energy Performance of Buildings and the related introduction of an energy certificate places the emphasis on the energy consumption of a building and the opportunities for reducing it. Since the certificate shows the standard of energy performance which a building has, it offers the user an insight into what auxiliary costs can be expected, and, for the owner, has an effect on the value or rentability of the property.

This new transparency requires from the investor and planner a consistent concept for increasing the energy performance. In order to ensure this concept is aimed at achieving a better evaluation in terms of the energy certificate, it makes sense to adhere to European standards, as they make up the figures relating to the overall energy requirements of a building. Therefore, the energy figures for the respective rooms are looked at first, then a reverse calculation of the distribution and conversion of useful energy is made, right down to the primary source of energy.
In this way, it is possible to see that the biggest savings can be made if one first avoids uncalled-for energy consumption in the rooms themselves. Only room automation is able to decide whether a light should still be left on after sunrise or whether a radiator should be turned off, because a window has been opened to air the room.

In this way, room automation is the most important tool in improving energy performance - with an amazing savings potential, too *.

40% of heating and cooling energy and
60% of lighting energy

can be saved by:

optimum use of daylight by combining sun tracking and constant light control
time program-controlled switching of mode change-over for heating or cooling
blocking the energy supply when opening windows
cooling through windows during the night
occupancy sensors

Room automation, therefore, reduces primary energy consumption by up to 50 per cent, thus halving your energy costs. The fact that efficiency-improving room automation is not just beneficial to the environment but is also a high-return investment.


The fact that efficiency-improving room automation is not just beneficial to the environment but is also a high-return investment is good news to any businessperson. The comparative cost accounts* for office or school building show that the monthly operating cost savings exceed the costs of financing room automation dramatically and assures 40% return with e.control!

Summary: from both an economical and ecological point of view, therefore, the use of an efficient room automation system such as e.control is nowadays your No. 1 choice!

Employees constitute the potential of every company. Their willingness to perform is necessary for success. Room automation helps to control their day-to-day working environment in such a way that they feel happy with it. In addition to energy efficiency, another purpose of room automation is to focus on the users and their well-being. A user personally decides, for example, how high the room temperature should be. Working in the background, the automation system ensures a glare-free and sufficiently lit environment ñ with as much natural sunlight as possible. To the relief of all concerned, users have full control themselves for the time they are in the room: they can override any function manually. Once the user leaves the room, the room automation can once again concentrate on the automatic functions for saving energy.


Changes in the corporate structure or a change of tenant often demand that buildings offer the possibility of free adaptation to changes in utilisation and a variable breakdown of rooms. The flexible-axis, decentralised and modular structure of the e.control room automation system supports the flexibility needed in an exemplary manner. It distinguishes between axis-oriented actuators and room-oriented operating and control functions. In this way, it is sufficient for implementing functional changes in terms of software using the easy-to-operate graphic e.control Designer Suite. Rewiring or the opening of false floors or suspended ceilings are no longer necessary.

Being highly decentralized, modular and LON based, SPEGA’s e.control room automation system offers better choice of control equipment to match any requirement and is easily integrated with any third party system.
