Overheating in UK buildings is gradually becoming a widely addressed issue due to two main factors. The first being the climate change which is causing mean temperatures to rise all over the world, and the second being design methods used in low energy buildings. As the main goal in UK low energy buildings is reducing the heating demands, the summer cooling demands are rarely dealt with. As the usage of high levels of insulation and maximizing solar gains can help significantly in reducing heating demands in winter, it makes the building more prone to overheating in high temperatures. This paper investigates the potential of overheating in UK housing, in the Regeneration of Trent Basin housing in Nottingham, which was a project under construction and designed according to the Zero Carbon Hub fabric energy efficiency standards. Design solutions as shading, infiltration and natural ventilation were also investigated to resolve the overheating issue, while keeping the heating demands as low as possible to meet the standard that was aimed for in the original design. Further testing was conducted to investigate the possibility of meeting Passive House standards, without changing the construction method, design layout or orientation. The dynamic simulations were run using Design builder software and PHPP (Passive house planning package).
