Tweakonomics 101

“Tweakonomics” is our word (partly tongue in cheek) for a basic philosophy of solving problems that includes the following characteristics:

• Look for small changes to current state / process that might deliver some results however small (one degree at a time)
• Execute, measure, repeat – keep trying new things
• Look outside the conventional (sometimes way outside) for things to adjust
• Keep pushing to do more with less
• Avoid big investments as long as possible

Here are some reasons why we think this approach is fruitful and ultimately more innovative:

• Contemplating big changes often sets people back and generates resistance, leading to stagnation.
• The same with big investments … it takes a long time and much justification to make the decision, and the process often either kills the change or distorts it to match conventional metrics.
• Making a big change / investment tends to lock you in … you can’t admit error if it doesn’t produce the results you were expecting and/or go looking for an even better solution.

Applied to HVAC systems, it becomes a “1 degree at a time” philosophy … warming or cooling 1 degree w/ least investment.

• Get access, if possible, to the space and the ability to make changes to thermostats, equipment, etc.
• Measure current state using your own “heat sense” – explore cool rooms, hot rooms, air leaks, cold walls, etc. – supplemented perhaps by an inexpensive laser thermometer
• Pay special attention to “legacy” system issues involving placement of heating/cooling units, ventilation, solar heat load, thermostats, etc.
• Make small changes in HVAC settings and air circulation
• Open or close doors, move thermostats, paint walls, add spot insulation
• Visit again and adjust, if it doesn’t work, try something new
• Avoid adding or replacing equipment until you’re absolutely sure there’s no alternative
