Hello,

I'm facing a though issues in establihing the corret LPB of a project and I hope you can give me some help. The project is the expansion of an existing airport and it includes:

1. the demolition of part of the existing terminal (around 60%),
2. the renovation of the remaining part of the existing terminal (around 40%),
3. the new construction of approximately 22,000 sqm.

In the portion that will be refurbished, part of the ‘Departures’ will be located. In the newly built portion, a part of the ‘Departures’ will be located, as well as all the other areas that make up the airport. The existing portion that will be refurbished and the newly built one will be phisically connected, not divided and not separated. To reduce costs, the part that will be refurbished will maintain some of the existing MEP systems that are not ASHRAE compliant. The portion of new construction will only have ASHRAE-compliant systems.

My questions are:

A- How can I certify the entire building? (both the new construction portion and the renovated portion).
B- Alternatively, how should I configure the LPB to certify the New portion (with ASHARE compliant systems) and exclude the existing portion (with ASHRAE non-compliant systems).

Thanks

Filippo

My call - if it's new construction, and it's an airport in whole, you cannot exclude parts of the building from certification. As I understand - the third part (22 000 sqm new construction) is an addition to the remaining 40 % of the initial building, compensating the demolished part. I would say that it's still mayor renovation and in whole qualify under NC standard - excluding existing portion of non compliant systems would be gerrymindering. File your explanation for the project and ask from GBCI approval to continue with such configuration and show points at energy efficiency credit by modelling as is (combined ASHRAE non-compliant and compliant systems).
