Yes and no.
The energy credits you are thinking of are found in Section 25C and Section 25D. These only apply to someone who uses the property as their residence. For section 25C credits, you must own the home and use it as your main residence. For section 25D, you don't need to be an owner or use the property as your main residence, you just have to use the property as a residence.
The credit for an efficient furnace is found in section 25C, which requires you to own the home and use it as your principle residence.. If you are a landlord, you don't qualify for section 25C unless you live in the home as your main residence (such as, it has multiple units and you live in one of the units.)
However, there are separate investment credits found in the tax code section 48 and section 179D that might apply to landlords. I don't know anything about how to qualify or what forms to use to claim the credits. Here are some links to start your research.
