Week 5 External Walls and Roof Systems Post-Lecture Resources

Here the Prezi version of the lecture today. Enjoy!

Week 5 External Walls and Roof Systems Post-Lecture Resources

Today, we looked at a number of different systems both for external wall and roof systems. The excellent series of videos from the Green Building Store in the UK again provided an excellent comparative viewpoint using traditional construction methods.

The following 3D images of the external walls and roof details (developed by Gerard Nicholson) of the Denby Dale Passive House provide a nice summary.

We also had a look at alternative solutions such as Insulated Concrete Formwork and Structurally Insulated Panels (SIPs) and what role they might play in the design and construction of a passive house. And just when you thought that external insulation was the solution to all your passive problems, Niall Crossan of Ecological Building Systems highlights some issues to watch out for.

Week 5 External Walls and Roof Systems Pre-Lecture Resources

This week we will have a look at a number of different thermal envelope options available, concentrating on external wall and roof systems. I refer to again to Energy Quarter's excellent video on the thermal envelope that was in the pre-lecture resources for week 3. The Passive House Institute also provide some useful guidance on thermal insulation requirements on different systems. Below is a video from the RTE programme 'About the House' hosted by Duncan Stewart, which highlights the use of recycled cellulose insulation in a timber frame house in Sligo.

Duncan has featured recycled cellulose insulation in a number of episodes.

Another system used in passive house design and construction is external wall insulation. Here Duncan (again!) looks at external insulation in a refurbishment project.

Week 3 Passive House Thermal Envelope Pre-Lecture Resources

This week, we will focus on appropriate thermal envelope design and construction options for a passive house. Passipedia, the excellent passive house wiki provides an overview of the important concept of energy balance.

Passive Development Ltd. provides a nice short overview presentation on the passive house principles in the following short video.

EnergyQuarter and Tomas O'Leary have produced an excellent series of videos including this one on thermal envelope.
