Smart home energy savings - update for 2010

Smart home energy savings
2010

Here's an updated graph showing the ongoing reduction in energy for our smart home. Driven mainly by continual improvement in the algorithms that control the heating, air conditioning and lighting the overall consumption of gas and electricity has continued to decline throughout 2010. It appears however that I am approaching the limit as to what is possible as the trend lines are beginning to flatten out. Going forward I'll continue to try to improve the algorithms but I'll also be on the lookout for any parasitic power-consuming devices and I'll be dealing with them using techniques like the smart power strip I mentioned here.

Home Automation

I've been working on home automation for over 15 years and I'm close to achieving my goal which is a house that understands where everyone is at all times, can predict where you are going next and can control lighting, heating and other systems without you having to do or say anything. That's a true "smart home".

ATAN curve for probabilities
