Conservation Of Energy By Home Domotics For Thermal Energy Conservation And Saving On Lighting
Domotics is not really new. During the 90's, I was CEO of a electronics high tech corporation and to impress our customers we decided to develop a PLC (programmable logic controller) based system that switched the lights and air conditioning actuators off and on depending on presence of people in each office. During the night the very same system acted as an advanced burglar alarm system that would either activate a bell, alert an alarm company, call phones or any combination thereof. Automatic and the alarm system just needed a key operated switch at the entrance of the office to deactivate and activate the burglar alarm; similar to any alarm installation. The question: "how much energy is conserved?" was only a secondary consideration at the time. That changed quickly after installation...
It worked great; but with one remark: When a person would be quietly behind her desk; sometimes the lights would be switched off. I still recall my colleagues waving at the sensor. In a way this was positive as it stimulated activity… But what was really a surprise was how much energy is conserved by this (in our view) uncomplicated system; we recorded savings of up to 35%. How can this be explained? In both a home and office environment, people often tend to not think about switching off the lights when they leave their room. I remember that before installing this system, the lights and air conditioning in the training room and meeting room were often switched on during most of the day. And, when I would come back to the office in the evening, cleaners or colleagues had at times forgotten turning off lights. Moreover, it was regularly too nice and warm in some rooms.
To my surprise, now, 20 years later, I did not see a system, comparable to the one as described above. Not many seem to worry about how much energy is conserved... What is out there today in the residential market is mainly gadget oriented; i.e. turning audio/video equipment on/off via the Internet or closing and opening curtains and similar actions. For office applications, costly building automation systems do exist. But, these systems do not feature presence . What could be the reasons for that?
First of all it could be the sensors; similar to what we experienced 20 years in the past. However, the expertise that allows 100% detection is available these days. Think of automotive collision detection sensors.
Secondly, it could be the control software, which is rather complex if done correctly. In essence, you want the same level of automation as in the commercial market, but for a cost measured in 100's of $'s to 1000's of $'s for advanced wireless systems or those systems with many functions and many input/outputs. But certainly not in 10,000's of $'s.
Wired or wireless
Wired is much more economical, but needs more installation labor. Especially in existing buildings, the cost difference may be compensated by the much lower installation.
As time passes by, wireless systems will likely become more economical as labor cost tends to rise, while Home Automation Systems will become cheaper as they are a mainstream product.
As contractors and architects do not yet have Home Automation Systems on their mind as a mainstream application for the home market, it will take considerable time and a lot of missionary marketing work by vendors. The bigger the low cost Home Automation Systems vendors are, the faster it would become reality. An alternative is that systems are being sold via Internet High Technology Marketing. This implies that massive article marketing, webinars and email marketing campaigns are used to realize market recognition.
During the GE ECOmagination Challenge (a technology competition) that runs until March 15, 2011), over 500 technologists, engineers, inventers and students contend for superior solutions in energy conservation. It is worth your while to have a peek in case energy conservation in the home energy efficiency marketplace has your interest. Moreover, there are interesting green energy solutions at the General Electric ECOmagination Challenge(contest).
