When it comes to making calculations of possible savings by altering temperature and humidity set points there are not very many tools to choose from… if any! If at the same time you have to deal with changing airflow, different weather profiles, room loads, etc. the traditional ways of calculating are simply not suitable. Since I had a lot of projects where these calculations were necessary, well, I’ve had to develop my own tool! It took a lot of work to get where I am now, even though I could draw on >20 years of experience working with energy, programming and tools. Up to this day I have analyzed savings in some 160 HVAC-cases, using many combinations of the following 18 features of my tool:
Here are some data about the program, just to show you how much is needed:
I run it on an isolated virtual XP-Pro machine (Parallels) on a MBP, and the typical execution time is 1:22 min.
The tool is not for sale, unfortunately. The user interface in not suited for the average user, and it would take a huge effort to improve it up to the level where it can be “left alone” with a HVAC engineer!
