This paper is based on a recently completed feasibility research - report of the Passivhaus standard retrofitting innovation activities - for the EU Horizon 2020 project REMOURBAN (REgeneration MOdel for accelerating the smart URBAN transformation). REMOURBAN is a major Future Cities demonstrator project supported by an investment of EU Lighthouse project scheme [1]. A block of terraced houses, which is one of the eight archetypes to be retrofitted at Nottingham demo site, will be cost-effectively retrofitted to a high energy-efficiency standard. Both static and dynamic simulation results play important roles in identifying appropriate retrofit standards and practice to achieve expected energy savings for such a major investment project. This paper aims to explore the building simulation effect on predicting the improvement potential in terms of energy savings under various refurbishment scenarios in the early project stage. The current feasibility study ushers the next project phases of implementation and real-time field monitoring, when detailed simulations are also expected to play important roles.
