Whenever the functional requirements of windows are discussed and prioritised, energy efficiency invariably appears near the top of the list. And rightly so – windows play a huge role in heat transfer in both commercial and residential applications. Any attempt to maximise sustainability that doesn’t adequately consider windows is sure to fail.
However, such considerations should look beyond the glazing. While high-performance glazing products are an important part of the sustainability equation, they are not the whole story. Other components such as window frames are also important.
For example, broken aluminium frames are worth considering as alternatives to standard aluminium frames. Apart from reducing energy consumption, they also carry low levels of embodied energy. They reduce condensation, deliver a high ROI, and future proof real estate assets.
Key Learning Outcomes
At the end of this presentation you should be able to -
- Explain the key requirements of quality window systems, including not only functional and aesthetic considerations but also environmental ones.
- Identify the role that window systems play in heat gain and heat loss, and therefore their potential for maximising a building’s overall energy efficiency.
- Explain the concept of a ‘window system’ and identify the fact that it extends beyond glazing to components like window frames.
- Outline the various types of window frames available and the benefits of each.
- Analyse a project brief in terms of both client objectives and environmental considerations to choose the best, most sustainable window framing option.

Samantha Anderson. Associate - Building Physics, Inhabit
Samantha is an Associate in Building Physics who has a comprehensive understanding of building performance, facades and all properties of glass.
Samantha is passionate about delivering high-performance buildings, but, in addition to this, trying to achieve greater clarity in the industry in regards to what a “high performance” building represents, and how these building can impact occupant comfort. Samantha strives to change the perception that “air conditioning” is required to maintain comfort, and make people realise comfort can be achieved through the building envelope alone.
