Kensington Blinds discusses how its high-performance exterior blinds can help architects meet net zero regulations.

With the race to net zero underway, it is crucial that we explore more sustainable building practices. According to GreenMatch, 40 per cent of global energy consumption comes from buildings, highlighting the immediate need to embrace energy-efficient solutions to meet the goal of net zero by 2050 in the UK.

An update to the pilot version of UK Net Zero Carbon Buildings Standard, published in September 2024, provides guidance for architects on the targets a building must meet. The Standard provides guidelines for designing buildings that have lower carbon output throughout their lifecycle and integrated sustainable design strategies that do not hinder functionality or impact negatively on aesthetics.

Alongside Part O Regulations (introduced in 2022) which encourage the construction of buildings that limit solar gain, it’s clear that architects starting new projects should be exploring solutions that control the temperature of new buildings, ultimately reducing energy outputs. While it’s imperative that we continue to focus on ways to insulate homes for winter, it’s also crucial to consider solutions to prevent overheating.

One such workaround is the use of external blinds, which stop solar glare from entering the home, while maintaining views out and letting light in. Blinds and shading expert at Kensington Blinds, Brian Farr, explains.

Why exterior blinds are a step towards the solution
“When it comes to compliance with Part O regulations or improving the energy efficiency of a home, installing external blinds is an effective solution, says Farr. “Fitted outside the window, exterior blinds offer enhanced heat protection by reflecting the heat from the sun before it impacts the building temperature. In this regard they are considerably more efficient than internal blinds.

Thanks to the open weave of the screen fabric used, at Kensington Blinds our customers can still enjoy clear sight out of windows and doors. The exterior blinds allow light to filter through while reflecting heat and keeping the interior cool. By stabilising the temperature of buildings, not only could the product save homeowners money on energy bills, but it also reduces damage to interior furnishings, such as fading and deterioration over time.”

Exterior blinds vs air conditioning
The IEA (International Energy Agency) predicts that the energy consumption used to cool homes will rise by 280 per cent by 2050 with the increased use of air conditioning. Farr adds, “Using external blinds reduces reliance on air conditioning systems, lowers emissions and minimises the strain on power grids, contributing to overall environmental sustainability. Additionally, air conditioning is known to circulate dust and allergens, while exterior blinds have a positive impact on indoor air quality, creating a more comfortable living environment.”

Exterior blinds vs solar glass
Architects often turn to solar glass as a solution to meet Part O regulations. “Exterior blinds add flexibility to the home, as they can be raised and lowered whereas solar glass is a permanent fixture,” says Farr. “They also have less impact on light quality than solar glass, which is often tinted. More effective at blocking heat than solar glass, external blinds have anecdotal evidence to suggest a temperature reduction of around three degrees. Another benefit of external blinds is that they are easier to retrofit with minimal disruption.”

Choosing the right external blinds
Stylish and luxurious, architects need not compromise their aesthetic vision in pursuit of sustainable performance. “At Kensington Blinds we are leading specialists in exterior blinds,” Farr continues. “With several different models to choose from, including TopFix Max, Fixscreen, and Panovista, our friendly team is on hand to help ensure you get just what you need. From beginning to end, we support architects, construction workers, and homeowners through the process, consistently achieving outstanding results.”
