How far is the concern of Machine Builder on Energy Efficiency?

Recently during a fair (on automation) a specific forum was dedicated to Energy Efficiency and participants expressed and exchanged their interests on the this key topic for Sustainable Efficiency.

Surprisingly we could classify their interest in 4 types:

1- HVAC and Lift Manufacturers: Definitely Energy Efficiency is in the core of interest as in Buildings HVAC is a high consumming part of energy. As well Lift machine is clearly identified by owners and investors  as an area to be optimized for Energy Efficiency.

2- Manufacturer of Hoisting system for Industry have identified that for new projects, a more optimized system for energy consumption in their machines could impact the global investment for Electrical equipments in the plant (by optimizing the Power need you can reduce significantly the cost of equipments, generators, transformers). This can give a strong competitive advantage for the manufacturers who master that area.

3-Manufacturers in some specific high performing area (Like packaging machine) express some interest as Mechatronics can bring strong benefits in terms of energy savings

4- Others (the most significant part) only see the Buzz around Energy Efficiency and are looking for the potential benefits they can get out of it!

So interst is there but still a long way in the journey for Energy Efficiency.
