Case Study: Sweco achieves over 25% margin toward NABERS UK 5 Stars with IESVE

Sweco achieves a 25%+ margin toward NABERS UK 5 Stars with Integrated Environmental Solutions

The customer, Sweco, was appointed as the building service and sustainability consultants for a major 12-storey London development. Their challenge was to carry out the detailed modelling required for the NABERS UK Design for Performance process, moving away from traditional compliance-focused design to ensure high-performance building operation. They used the IESVE software from Integrated Environmental Solutions to meet this challenge.

Integrated Environmental Solutions' IESVE was used to create a physics-based digital twin of the building, allowing Sweco to predict service loads and perform a detailed energy breakdown. The results indicated a comfortable margin of over 25% to achieve a NABERS UK 5 Stars Rating, which equates to energy savings of over 50% compared to a typical UK building. This performance was attributed to a façade-first approach and an energy-efficient, all-electric design optimized using the IESVE software.
