In past jobs I have managed test and quality assurance groups where taking readings, measuring output, comparing data, and recreating situations have been critical to doing a good job. I believe that measuring and documenting results is a great way to help understand how a system works and to demonstrate how changes affect the system.
Take your heating system, for example. If you cover up the drafts under the doors and windows how much money can you really save?
This is a complex problem because you would need to know:
- How much cold air is getting in through the draft over some period of time
- How much does that lower the temperature in the whole room or the whole house
- How much energy is used in your heating system to bring the temperature back up to your desired temperature
Fortunately the energy experts have been working on creating some standards so we don’t have to do the complex calculations ourselves.
As soon as I understand them… I’ll pass on the simple answers
In the meantime, buy some ‘door snakes’ — they really can cut down on the drafts and save you some money.
Or how about this one:
