Specialised Services

SBEM Calculations

Determine CO2 emission rates for non-domestic buildings and ensure all regulatory and planning requirements relating to standards for energy performance of new and existing buildings are satisfied and documented through the provision of an EPC.


Certify communities and buildings to demonstrate cost-effective, sustainable performance for the building’s lifecycle to investors, clients and planners. In addition, BREEAM and SBEM can be combined enabling the maximum number of credits to be gained under the energy section of the regulations.

Daylight Calculations

Deliver all the daylight calculations you need to score credits under BREEAM using dynamic simulation software.

The WELL Building Standard

WELL is a performance based system for measuring, certifying and monitoring features of buildings that impact human health and well-being. WELL is composed of over 100 features that can be applied to buildings to provide a tangible health benefit to its occupants. Our in-house WELL Accredited Professionals can guide project teams through the certification requirements in order to achieve a WELL rating.

Condensation Risk Analysis

Make sure condensation doesn’t get overlooked – all our consultants calculate condensation risk in strict accordance with the BS 5250:2011 Code of Practice.
