Description: Park hill is one of the most important buildings in Sheffield because of its history in culture and social housing. It is a Grade II listed building and also the largest listed building in Europe. For Phase II the proposal by David Mikhail of Michail Riches Architects, won the competition and proposed to retain the brick walls. My proposal is to retrofit the apartments according to EnerPHit standard. Analysis for apartment type A indicates that there is currently a high probability of overheating which will continue into the future. Proposals to solve this problem include lower u values for the walls, timber triple glazed windows, external shading and night single sided or cross ventilation.

SHADING DEVICES
Calculating and designing shading devices based on overshadowing masks and key dates.
Prepare a 3d model using design PH to import the data in PHPP and analyse the impact of the shading device on the energy consumption.
