I'm trying to connect some dots between how energy is lost, and how it's replaced, and how best to think about good design.
Is there something to thermal inertia of insulation and structures, "Steady State" temperatures, and managing the strategy by which the energy lost from a structure is replaced?
Is there significant savings opportunity by designing AND running a piece of equipment optimally, or is the penalty from oversizing and not optimizing insignificant?
RICHARD RUE of EnergyWise Structures has a process of sub-metering HVAC and guaranteeing energy bills on his structures. So he's learned a lot about case by case consumption. They also have some interesting things to say about sizing:http://bit.ly/EnergyWiseOnSizing
ROBERT BEAN of HEALTHYHEATING.COM talks about optimizing heat transfer from combustion by running low and slow. That the colder you can design your equipment to run the more latent and sensible heat you can squeeze out of the heat of combustion.http://bit.ly/beanNthermostats
DAVID BUTLER of Optimal Building Solutions (and moderator of the RESNET BPI group) - Has these nice essays:

Given all this perspective, and the concept of momentum and conservation of motion, doesn't it make a lot of sense to keep our flywheels spinning and the equipment gently running, ever so slightly adding or removing btu's to match load on the structure?
