You can now set it as low as 10.5 °C. I tried different temperatures and lower temperatures seem to give a better baseload estimation (15.5 °C estimates the base load too low, based on gas usage in non-heating months) but a worse correlation with HDD. I can't see any communities or any other accounts, maybe that is because I'm only using it as a trial.

The transition to their new system seemed a bit bumpy but works pretty smoothly now. I still input weekly data into it. If nothing else it's a nice simple source of HDD data and an off-site data store, and if I miss the Monday meter reading window due to hectic Monday mornings it adjusts pretty well.

I think a lot of people gave up on it because they wanted it to do comparisons between buildings, but that was never an issue for me.]]> Use of Heating Degree Days http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12847&Focus=215322#Comment_215322 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12847&Focus=215322#Comment_215322 Tue, 16 Dec 2014 18:25:38 +0000 atomicbisf Use of Heating Degree Days http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12847&Focus=215323#Comment_215323 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12847&Focus=215323#Comment_215323 Tue, 16 Dec 2014 18:34:29 +0000 atomicbisf Use of Heating Degree Days http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12847&Focus=215389#Comment_215389 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12847&Focus=215389#Comment_215389 Wed, 17 Dec 2014 13:26:17 +0000 Ed Davies
