Domestic Hot Water (DHW) is an important source of energy consumption for any type of building. I attach here the slides of a short (20 mins) talk I gave on this topic yesterday, at the Energy7 conference in Manchester UK:

Analytical modelling and prediction formulas for domestic hot water consumption – slides

I briefly outline an analytical bottom-up method to model DHW consumption accurately. We

 1) derive the correlations between occupant groups and different seasons => MAIN TREND OF CONSUMPTION
 2) generate a PREDICTIVE FORMULA for the DHW consumption of unknown occupant groups.

The slides are in PDF format (just use the pgup/pgdn keys on your keyboard to scroll). The talk is based on a paper I published last Spring, described in this entry of my blog.

Greetings from Manchester!
