Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.

What defines \'finished floor\', \'finished ceiling\'. Example - the project we are working on was a former warehouse space converted to offices. The existing concrete slab remains intact, but we have selected a Shaw-Eco carpet to be installed over the slab. Is the slab considered a retained area or not because we are putting a new finish over it? Example - we maintained existing interior block walls but furred them out and put a new finish on due to their condition. Is that calculated as a retained area since it was not demolished? Example - we maintained the open exposed ceiling but painted it white for daylighting and lighting benefits. Is this still considered retained area? Please provide explicit guidance on how to deal with these calculations.
The project team is asking for clarification on how areas of specific items are to be dealt with in Finished Surface Area calculations. 1. An existing floor slab is considered part of the structure and should not be included in Finished Surface Areas calculations. The area of new carpet installed over the slab is to be included under Completed Design Area. 2. Since the existing wall was refinished, the finished square footage area should be included in the Completed Design Area column only. 3. Whether the existing exposed ceiling receives paint or not, the area of the retained exposed ceiling should be entered consistently under all three categories.
Our project is a Commercial Interiors project where our client is to occupy 3 floors of a new construct building. The landlord as part of his construction program has fitted out the tenancy floors with raised floor and ceiling tiles, however this was done to the landlord\'s specification without the input from our client (ie. outside of our client\'s CI scope of works). As part of the CI project, we have decided to retain and integrate the raised floor and ceiling tiles, therefore avoiding wastage etc. We have therefore followed the credit intent even though the ceiling and floor is new. Will reuse of the ceiling and flooring in this instance count towards this credit?
The intent of MRc1, Building Reuse, is to reuse existing building elements in a previously built-out space. As such, in the case described above in which the landlord has provided a raised floor and ceiling tiles in a newly constructed building, it is simply good design practice to integrate these elements as it will save in the cost of demolition, as well as the time involved with the removal of these materials. Therefore your approach is not acceptable to achieve the credit.
The tenant has historically stayed in the same location for more than 40 years, but will not enter into a lease. Will it be acceptable to use the tenant\'s lease history and a signed letter of intent from the owner as an alternate compliance pathway for MR Credit 1.1?
Lease terms of less than 10 years, regardless of the owner\'s lease history, do not satisfy the credit requirement of a minimum 10 year term.
