Alignment between BREEAM and the Fitwel certification system - KBCN0737

BRE, as an independent and impartial research-based organization, is working with the Center for Active Design (CfAD) and International WELL Building Institute (IWBI) to promote and improve health and well-being in the built environment. The aim of both these agreements is to support our clients who want to pursue either Fitwel or WELL alongside the BREEAM standard.  To simplify the process for project teams pursuing both assessment methods, BRE has worked together with the respective organizations to compare performance requirements, identify specific documented credits and evidence that will be recognized by both organizations to streamline the process of achieving dual certification. This work demonstrates the significant synergies between the various methods and the efficiencies that exist between their respective assessment and certification processes. Because of BRE’s unique position as an impartial organization, it is possible to form these important collaborations with like-minded organizations to work together to harmonize approaches to health and wellbeing in the built environment across their standards, research programs and services.  Further information can be found in the Resources section of the BREEAM website:  For Fitwell  For WELL – 

Building Details – Asset Types and Subtypes - KBCN1413

BREEAM USA In-Use can accommodate assets with a wide variety of space use types.  These space uses are included in the online tool to refine the Energy Calculators for Parts 1 and 2.  The table in the link below describes the space use types that can be accommodated and the corresponding Asset Type and Subtype that should be selected in the online tool.  If the space type you need is not described or you are unsure which is correct, please submit a Technical Question describing the space use type to BIU USA 2016 Asset Types

Multi-tenanted assessed areas – Demonstrating compliance - KBCN0984

BREEAM USA In-Use requires each tenanted space to be assessed separately for each question and to determine the final score based on the tenanted space with the lowest scoreAn example of this question type is HEA 06, for which, to select an answer option, the relevant requirement needs to be met by all tenanted areas. For example, if there is an asset with five tenants where four tenants provide mains connected water provisions, but only one provides access to non-mains connected water provisions, only one credit can be awarded.  However, this approach is not required in the case of questions where credits are awarded based on a percentage of compliance.  In these cases, Assessors should consider the entire assessed area as a whole. An example of this question type is WAT 04, where the percentage of low-water use fittings, regardless of their location in the building, is assessed in one calculation.
