This security control relay Wieland Electric consumes less energy than a standard equivalent component. Samos PRO control relay has a CPU and can manage 96 safety inputs and 48 safety outputs.

Ignored for a long time, the electricity consumption of equipments and panel automation has begun to interest manufacturers and some contractors. Until now, the few Watts lost in thermal heating by a circuit breaker or an automat had been going almost unnoticed in a world without energy balance.

Today, manufacturers attitudes are changing and their R&D teams are working on this subject. The low-energy impact intrinsic to the equipment sometimes also becomes a sales argument. (more…)

An office tower without switches

No switches in this tower, but an automatic lighting management.

In Dijon (Côte d’Or, France), the Elithis Tower is the outcome of strong reflections about energy performance and strategic thinking. Operational for 2 years, this ten-storey and 5000m² office building is the showcase of Elithis Ingénierie’s (100 people) expertise. The purpose: to reduce as far as possible the overall of the building (heating, cooling, ventilation, lighting). In fact, when you take into account its photovoltaic power production (560m² of panels on the roof) the building has, today, an overall consumption of 0kWh/m²/year for the previously mentioned usage!

Electrical switchboard opens up to communications networks

The current trend: intelligent buildings are currently undergoing a long awaited convergence movement. In other words, the many low-current networks, which were previously independent of one another, are merging into an Ethernet standard, where communication, security and technical management functions (digital display, public-address system, video surveillance, access control, fire protection, anti-intrusion alarms, lighting management, HVAC, elevators management… ) within the building or infrastructure are concerned. Though, the convergence movement is not new; its beginning goes back to the 80’s and 90’s, today it is speeding up strongly and one consequence is that electrical switchboard connectivity becomes a must.

Nowadays, the world is going green and everyone is behind optimising energy and resources. For better energy optimisation, we need to first better know about our behaviour. And here comes the concept of energy monitoring tools.

There are multiple energy monitoring tools available in the market such as Dreamwatts, Greenbox, etc. But the whole industry shook its head when Google decided to enter in this field with its free Google Power Meter.

So, what is Google Power Meter? Why it is creating so much buzz?

Let me sum-up what was discussed in previous articles about :
> no building automation ==> high
> fully automatic building ==> occupants can’t adapt their environment to their comfort needs, feel “trapped” by the system and may thus become less productive

So is there a solution to reach both occupant comfort needs and ?

Yes, but the right balance is not easy to find …

how to find the best balance between automatic building and occupants comfort?
