There are two things that you may not think that Energos requires. The first is that Energos needs to have a Heliodon in the same design layer as the walls. It uses this Heliodon it on to find the location of the site. It needs have the location of the site because the climate data changes from location to location. The other thing that you may not have thought of is that Energos requires spaces. It requires the spaces so that it knows which rooms or parts of the building are habited, and it also needs these spaces to calculate the volume.
