Frequently asked questions
Do you also provide electrical and structural designs?
Alongside mechanical designs we also provide electrical and architectural-structural designs, so that the documentation is complete.
Do I need a design for a heat pump or a PV system?
It depends on the size of the system and the type of work. Grant applications often require a main design or a designer’s statement. We will check what your case requires.
