ICT has been identified as one possible means to design, optimize, regulate and control energy use within existing and future (smart) buildings. ICT could not only be used for decreasing the energy consumption in buildings, but also to create new business opportunities driven by the need of energy efficiency.
Monitor that the performance and energy efficiency are stable during the life time of the building and do not decrease
Achieve more energy savings combining the operation of the different systems in the building
Provide feedback to change user’s behaviour and install new energy efficient technologies or fine tune those already installed
Battery life of the devices
Some portable devices are heavy
Small screens and keyboards
The feasibility of an investment in ICT for energy efficiency depends on a variety of factors, such as: structure of energy bills, the actual or expected consumption levels, features of the building, users’ profiles, etc. For this reason, prior to the investment, an audit should be carried out to assess the possible savings to be achieved, combining traditional retrofitting actions with the use of ICT awareness tools.
