Degree days measure how far outdoor temperature sat above or below a reference temperature, multiplied by the days it held. Cooling and heating degree days let a baseline account for weather, so a mild winter is not mistaken for a saving. See weather-normalized baselining.
Six months minimum and twelve preferred, from utility bills or meters. Uploading those bills to Aqueduct gives a building performance results on the first day instead of after a year of monitoring, and the guide explains the data checks that keep the model honest.
The guide explains how a regression baseline relates to both protocols and where each fits. Your team or consultant chooses the protocol and option for a project, and the guide shows what data each one expects. See measurement and verification.
Energy and facility managers who need to tell a real saving from a mild quarter, finance and portfolio leads who want the gap priced in dollars, and sustainability teams whose figures face review. It assumes no statistics background.
