in response to Re: Concept of copying devices, posted by Phil
Thanks for the info. I am trying to create a running total of Heating degree days for the season, and also create "last month's" HDD. My daily HDD seem to be correct, but I'm having trouble accumulating monthly HDD. Here are my devices and expressions:
d21 is T_Oustide (outside live temperature, scaled/offset to deg F)
d34 is d21L+zero (copy the device, scale -1 and add 65 to get heating degree hours and apply B accumulation)
d35 is d34D+zero (copy the device and scale by 1/24 to get daily HDD.)
That works fine to give me daily HDD at device 35. Here is where I'm stuck: How do I create running HDD that do not reset every day? I thought it should be as simple as creating d36 = d34M+zero and apllying a 1/24 scale factor, but the posted data is not right. Thanks ahead for any insight.

This site is all about building a cool, energy efficient house, that makes maximum use of earth sheltered design, passive solar heating and cooling, geothermal exchange energy management, and right sizing of the house for it's designated use. The home's placement is on a south-facing hillside in Deep Creek Lake, Maryland. This site describes the design process, the technologies used and the expected results. We also have a comprehensive Links Page for anyone who is also interested in designing a similar project.
