The Bridges is a shopping destination in Sunderland with 100+ shops and attracts over 21 million customer visits per year. IES Consulting were commissioned to run dynamic thermal simulations as part of an investigation for a refurbishment program. The modelling included generating a baseline assessment of the centre as it then operated. Following this a number of individual upgrade scenarios were tested providing feedback on their cost benefit, such as enancements to the ventialtion control. The final stage involved combining some of these scenarios into an overall assessment which fed into the refurbishment plan.
