Additional comments on JAHUS savings

Comments:
In a recent blog post I estimated the savings of our JAHUS project to approximately 5.8KW (effect of improved isolation, heatpump and the heatexchanger/ventilation system). Not all days of January will be below -10C, but the savings do not change dramatically from -15C to -5C:

• improved effect of the heatpump (COP goes from 2 to 3+) 
• slightly lower savings from the isolation and ventilation system
• 5KW as an average for January is probably a good estimate.          

The estimated total energy savings for a full year is 15.000 KWh. With the average total price of electricity (incl. a fixed cost per month for "rent of powerlines") at 0.85 NOK/KWh - the savings will be 12 750 NOK/year (or 2236 USD).

Note: We do, however, hope that the savings will be closer to 20.000 KWh, and this can only be verified when we get the invoices for the full year (and can compare with the relevant numbers from 2009).

No progress to report today.
