This brief article suggests that dumb control systems for lighting, AC and other such systems make efficiency difficult to achieve. Better control systems for these amenities would result in more power savings.
No Efficiency Without Controls
Interestingly, the comments point out that more intelligent design of the buildings would reduce the need for systems that must be controlled. Dumb building designs require smart control of systems, smart building designs reduce the need for systems.
Why do you keep a big gas-fired/electric-powered tank of hot water in your cold basement? Wouldn't it make more sense to keep it in a south-facing solar collector box in your attic?
Why do you have to use electric lights in your house during the day? Wouldn't it make more sense to use daylight?
Why do you light up the whole room with 1000W of incandescent bulbs? Wouldn't it make more sense to use 100W of directed task lights and maybe some low power, directed ambient lighting?
