Hello. I have this question to do.
It is common knowledge that solar heating for a large office building is technically different from a single-family home.
I don't know where the mistake is. Help please.
What you're trying to do is compare "heating a large office building" and "heating a single family home." However, this makes it sound as though you're comparing "heating" to "a single family home." You need to add some words to make it clear what you're comparing, e.g., "...is technically different than solar heating for a single-family..." or "...from that for a single-family..."
