The influence of façade design on the optimum window to wall ratio and overheating rate in UK Passivhaus dwellings for current and future climates: A Parametric Design Method (2017)
Presentation / Conference
Lavafpour, Y., & Sharples, S. (2017, July). The influence of façade design on the optimum window to wall ratio and overheating rate in UK Passivhaus dwellings for current and future climates: A Parametric Design Method. Paper presented at Passive Low Energy Architecture

Many researches of overheating in buildings have focused on the optimisation of the window to wall ratio (WWR). However, the physical form of the building envelope has not been widely considered as a factor in optimisation investigations. This study...

The potential of inclined walls to reduce overheating risk: A Passivhaus case study for UK current and future climates (2016)
Presentation / Conference
Lavafpour, Y., & Sharples, S. (2016, July). The potential of inclined walls to reduce overheating risk: A Passivhaus case study for UK current and future climates. Paper presented at Passive and Low Energy Architecture

This study used probabilistic climate change scenarios from the UK Climate Change Projections to determine the future overheating risk in an existing Passivhaus dwelling under a high emission 50 percentile scenario in London. Dynamic thermal simulati... Read More about The potential of inclined walls to reduce overheating risk: A Passivhaus case study for UK current and future climates.

Impact of the envelope geometry on cooling demand in very airtight UK dwellings under current and future weather projections (2014)
Journal Article
Lavafpour, Y., & Sharples, S. (2014). Impact of the envelope geometry on cooling demand in very airtight UK dwellings under current and future weather projections. Energy Procedia, 62, 421-430. https://doi.org/10.1016/j.egypro.2014.12.404

© 2014 The Author. The Passivhaus strategy employs super insulation to reduce the heat transfer through the building envelope. It has been argued that super insulated homes are vulnerable to summer overheating risks, even in the current climate. The...
