SAP and BREDEM

BREDEM-12/SAP 2009 Occupancy Comparison

Figure 1: BREDEM-12/SAP Occupancy comparison

This is a bit of a follow up to a post I wrote in December 2012. That post dealt with how emissions from cooking are calculated in SAP 2009 (if you don’t know what I’m talking about, and/or want further detail, I recommend reading that post). Part way through I wondered about comparing the energy use from appliances and lighting as calculated by SAP with that calculated by BREDEM-12. This post deals with those comparisons.

Attempt number 5 or 6 to get into the mystery locked room. There had better be treasure!

Ready To Go

Ready for the kickoff

I headed north at the weekend, leaving Heather to entertain herself. I was up in Newcastle to see my Dad (unseen since Christmas so we had to exchange christmas (and birthday!) presents). Before that I took in Newcastle play West Brom which we actually managed to win. A good little trip north then.
