Entire buildings present opportunities for implementation of the greatest number of WELL features. This project type applies to new and existing buildings and addresses the full scope of project design and construction as well as aspects of building operations. It is relevant for office buildings where a minimum of 90% of the total floor area is occupied by the building owner and is operated by the same management (i.e., up to 10% of the building may be occupied by a different tenant or operated by different management). For example, a large office building may rent out the ground floor for retail or restaurant purposes; in these cases, the non-office area would not be subject to requirements of the WELL Building Standard or used in area calculations.
