Baselines & Signatures Check

1. An energy baseline is:

The lowest energy a building could useA normalized reference period of consumption against which improvements are measuredThe energy used on the coldest dayAn auditor's opinion

2. An energy signature relates:

The building's name to energy useEnergy consumption to external drivers like temperature, production volume, or occupancyThe utility company to the building ownerEquipment serial numbers

3. A regression analysis on energy data helps you:

Complain to the utilityQuantify how much a change in driver (temperature, production) affects energy useFind who's responsible for wasteCalculate the cost of fuel

4. When decomposing a change in consumption, you separate:

Real savings from changes in weather, production, or occupancyHeating from coolingFixed from variable costsOld from new equipment
