We are planning to renovate an existing building which is used as an office, aiming for LEED CI certification. The office is a two-story building standing alone and the entire building is leased by one company. Basically, we cannot do anything with parts of the owner’s property such as the envelope, HVAC, service water and lighting besides the interior space leased as a tenant. However, our client wants to add some LED lighting fixtures and a couple of HVACs to the existing ones getting permission from the owner(we are also not supposed to renovate the envelope of the building).
We recognize that we only need to apply this prerequisite to the interior fit-out within the scope and budget, however, in this case, is it all right that we don’t need to address the existing HVAC and lighting? We are not sure whether or not all we have to do is to calculate the additional ones and to comply with them except the existing ones.
Thank you in advance.

I've recently done research on lighting for a CI project - the lighting that serves the tenant space must meet the EAp2 prerequisite. Unless your lighting design is unusual, this would typically mean you will need to replace all the lighting in the leased area to meet the lighting power density requirement (and perhaps some of the finer points of the standard.) Lighting in common areas not leased by the tenant (if any) are exempt.
I haven't looked into the IEQp1 options as the base build of all my CI projects have met the standard, hopefully someone else will chime in with that information.

For HVAC you only need to address what is in your scope. For lighting I think you must show the 10% reduction, so compliance depends on the combination of already installed lighting and any being added.

Hi Michael and Marcus,
We appreciate your answering the question and giving us helpful advices. As to the lighting, I understand what we have to do, that is to say, we must include all the lightings both already installed and being added to meet the compliance. With regard to the additional HVACs intended to install, there is still a question left for us. Our scope of the work in this project regarding the HVAC is only the ones that our client wants to add, and the existing HVACs are not regarded as our scope.
In this case, is it all right that we need to make the added ones complied with ASHRAE 90.1–2007? Or are we required to comply with all the HVACs as well as the lighting?
Thank you in advance again.

Since it is a matter of minimal compliance and not overall performance improvement relative to minimal compliance, I think you only have to meet the requirements for the new HVAC equipment within the project scope.

Hi Marcus,
We can make it clear. Thank you very much for your advice.

We have found that uploading Interactive Compliance Forms of Building Envelope, HVAC and Service Water Heating at the EAp2 Scorecard is "optional", and there is no such form for Power at all. That brought us back here.
Does it mean we do not have to submit the HVAC form if we do not intend to take EAc1.3 credit?
Aren't we expected to submit anything but signiture at the EAp2 Scorecard for Section 8: Power for any project even if the project has alternation on it?
