Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

Is there a way for southface staff or guest experts to "pin" or "tag" the "right" answer in a forum question? It might be useful to designate the right answer and pin it to the top of a forum thread. I don't want the answer selected via crowd source but by staff or volunteers. Thanks.

Related to some recent questions on site-specific sun/wind analysis and early energy modeling tools, are there any tools that account for nearby topography (like bluffs) or large buildings/vegetation in energy calculations? Or favorite methods to estimate its impact particularly during early massing studies?

Thanks,

This is sort of dragging up an ancient topic, but curious how your firms are currently addressing accreditation (LEED AP, WELL AP, LFA, etc.). There was a time when we were all talking about this, and a number of firms instituted requirements, but it has been a long time, and I'm curious how it's looking now in 2024. Thanks!

Stick-framed walls are labor intensive and have to be sealed and insulated in the field, where conditions are not ideal; this can lead to poor thermal performance.
