Talks: Introduction to Passivhaus : Specifying windows for energy performance

Show large map

Join us for a morning of two talks by experts in low-energy buildings. This event is perfect for self-builders and professionals interested in building low-energy homes, and also for anyone considering upgrading their windows for higher energy performance.

We kick off with an introduction to the Passivhaus approach to building homes that need very little heating and have a healthy, comfortable environment inside. We'll then hone in on a really important feature to get right in a low-energy build or retrofit: the windows. 

Both talks are by experts from the Green Building Store, whose kind support means we're able to offer this fantastic event free of charge. 

The Green Building Store is committed to low-energy building to help reduce carbon emissions and cut heating bills. The most effective way of doing this is to focus on the building fabric, using high levels of continuous insulation, together with stringent airtightness and advanced ventilation strategies. To achieve this, the Green Building Store is a strong proponent of the Passivhaus approach, which can cut a building’s heating need by 90% compared with the UK average.

As well as reducing energy bills and CO2 emissions, low-energy and Passivhaus homes and buildings can improve the quality of life for occupants. Constant warm and even temperatures, eradication of mould and condensation issues, and elimination of cold spots or draughts can really make our homes and buildings more comfortable and enjoyable places to be.

Here's what our two talks will cover:

1. Introduction to Passivhaus 

  • Introduction to Passivhaus methodology & standard
  • Specification required to achieve Passivhaus certification
  • Windows & doors: Passivhaus requirements and importance of installation detailing
  • Airtightness products & techniques needed to achieve Passivhaus requirements
  • MVHR: what it is and how to ensure optimal performance

2. Windows: how to get best value & performance

  • Options to reduce cost or get best value
  • Real value engineering
  • How window & door style and design affects performance and cost
  • Ensuring value at quote stage
  • Window requirements for Passivhaus certification
  • U values / Psi values / G values
  • Why triple glazing?
  • Installation & detailing (airtightness, thermal bridging & avoiding overheating)
