Deemed to Satisfy and JV3 assessments

erbas™ SUSTAIN is experienced in delivering Deemed to Satisfy (DTS) assessments and optimising building fabric and glazing systems.  Where the DTS outcome is not practical, the team strives to provide a solution via JV3 modelling. We balance environmental performance and project costs, and work closely with architects and the design team to develop cost-effective options that meet the client’s vision for the development.


Our capability includes NatHERS modelling of residential developments and providing advice on improving energy efficiency through optimising building design. This includes exploring options in shading, orientation, building material construction, and glazing systems.
