Collaborative Approach to Design: Case-study of Future-Proofing A Paragraph 80 House

Duran, Ozlem; Elnokly, Amira

Abstract

This paper demonstrates future-proofing preliminary design phase of a Paragraph 80 (DLUHC, 2021) housing case study by using Building Performance Simulation. Paragraph 80 is about the design of new isolated homes in the countryside defined as outstanding buildings of the highest quality in the UK. The objective of the simulations was to optimise the trade-off between the architect's vision, the client's requirements and the building physicist's focus to achieve maximum energy efficiency, investigating the applicability of net-zero operational energy and providing thermal comfort in the current and future climate considering current low occupancy and higher design occupancy. The results show operational net-zero energy is achievable and no overheating is predicted in the current weather however local active cooling is necessary for 2050 despite passive cooling mitigations. A more definitive Paragraph 80 policy is needed which also requires whole lifecycle carbon analysis and achieving net-zero carbon.
