Dear all, Sorry in advance for this lengthy thread. In a current (European) project the certifying building will be supplied with district heat from a large city network.

Hi everyone, I have a project (residential building) that has a roof terrace with self-service amenities such as kitchenette, chimney, lounge areas, etc.

On PI Form 3 under complex occupancy it asks you to upload PIf3-1. Is there a form provided for this or do we create our own?

I'd like to understand better how to input what is needed in Table L-1 for our solar thermal system (our solar PV system was easy to input).

Our office building includes a daycare center, with approx 100 kids on a daily basis. Would the kids be factored into the calculations using the same method of transportation as their parents?

Ruben, I don't see why you would count the section that is to be demolished in the project GSF.

Hello, The project I am working on will re-use a significant percentage of its wastewater for irrigation purposes.
