Building System Design Synthesis and Optimization

The ASHRAE 1049-RP was led by Professor Vic I Hanby, Professor Jonathan A Wright, and Professor Plamen Angelov at Loughborough University

HVAC System design synthesis


An ASHRAE study developed a model-based design optimization process to help reduce the capital cost and energy use of buildings. This design process can be used to evaluate design options including choices of system components, physical connections between components, and the size and operation of the components. This approach was evaluated on two example design briefs and shown to identify novel HVAC system configurations and an energy reduction up to 15% lower compared to an existing benchmark system design. The report presents a new metric for evaluating ‘effectiveness’ of a system in operating with the minimum possible energy used.
