ᐅ Floor plan design with cooling load calculation

Hello,

As a client, I want to participate in designing the floor plan for a passive house myself. Besides being able to illustrate basic furnishings (stairs, kitchen, WC, bed, etc.) in the plan, I especially want to perform at least an approximate cooling load calculation. The motivation is to estimate the effort required for surface cooling (on the ceiling) in selected rooms.

For a start, the software mh-BIM Starter, formerly TGA-Tools, seems to be a good choice. However, in the basic version, I miss both the mentioned interior models and especially the cooling load calculation.

- Can anyone recommend free and well-organized DWG / DXF libraries to add basic interior elements?

- What options are available for cooling load calculations besides the commercial extensions of mh-BIM?

Thank you
Andreas

For the modeling, my focus is not on experimenting with different floor plans. Rather, it is about questions such as the approximate impact of varying window areas and orientations, the proportion of shading they receive, or the exact choice of glazing.

Keep in mind the limits of achievable precision: if you don’t have a park-like plot, the neighbor’s terrace privacy screen can have an influence on the low winter sun that easily exceeds two degrees.
