A recent article in the RIBA J has had us thinking more about how we incorporate shading in our designs to combat overheating. The full article can be read here: https://www.ribaj.com/intelligence/climate-adaptation-five-tips-on-shading-design
Here are our top take aways.
Shading Design hasn't become Mainstream in the UK yet
The UK Building Regulations requires developments to address overheating under Approved Document Part O (2022), but prioritises smaller windows and increased ventilation over external shading. However, increasing the demand on our ventilation and cooling systems leads to unacceptably high energy bills, over-demand on the grid and carbon emissions.
Shading Should be Central to Housing Design and be built in from the Start
When designing a new home or extension we will ensure that the form and elevation responds to the local climate and, where possible, orientate the glazing to be shaded from the summer sun. We can undertake sun path analysis diagrams to do this and offer 3D visuals to show how the form can impact how much direct sunlight is experienced by the space. Alongside this we will optimise the amount of glazing and shading for each elevation depending on tis orientation.
We always strive to design dual-aspect dwellings that can naturally cross-ventilate and shading devices should be specified to support natural ventilation. Using external shading devices that are integrated into the fabric of the design, such as, deep window reveals, vertical fins and roof overhangs, can add to the aesthetics and it is essential that they are designed in from the start.
If you have any questions about future-proofing your home with integrated shading, please get in touch with us here at RLDM. We would be more than happy to help!
