Sustainable Ideas Seen at the London Build 2023 Expo
Read on to find some innovative ideas that could help lower the environmental impact of construction projects
The climate collective, Zero Construct, were exhibiting at the show to offer advice about sustainable construction practices. The aim of this community of construction professionals is to encourage the industry to place greater importance on carbon efficiency at all stages of a project.
“Construction emits around 4 billion tonnes of CO2e [CO2 equivalent] per year,” said Zero member and eco-consultant Jonathan Munkley during the discussion, ZERO Uniting Construction to Tackle Embodied Carbon. In an effort to deal with the problem, Zero is putting together a Playbook. This useful resource will be a practical guide for carrying out low carbon projects and is scheduled to be released in January 2023.
A similar idea came from fellow exhibitor New Era, which has partnered with Green Biofuels to supply a fossil-free, renewable fuel as an alternative to fossil fuel-powered generators.
Elsewhere, repair and restoration firm Plastic Surgeon (pictured) was exhibiting to explain how it can help firms adopt a repair-first approach by restoring all manner of hard surfaces, from stone, ceramic and metal to wood, MDF and acrylic.
A fellow exhibitor at the show was EDGE (Eco Design Green Environment), which aims to help home professionals make sustainable choices by bringing together brands dedicated to circularity and sustainability into one showroom. Products highlighted at the show included Cocoboard (pictured), which is an MDF substitute made from coconut husks and natural adhesive, and Zero Waste Works’ reinforcement fibres made from waste materials, which can be used in numerous ways in construction.
In terms of renovating existing spaces, it takes thought and planning to recycle materials, but Peter Swallow of Grimshaw Architects said, “There are reuse routes for most materials.”
Insulation: There were some interesting sustainable insulation ideas on display at the show, including IndiNature’s natural fibre insulation boards and batts. Made from hemp grown in Yorkshire and formed into insulation at a zero-waste site near Jedburgh in the Scottish Borders, the material is projected to last around 60 years, after which time it could, in theory, be recycled.
Elsewhere, Marmox explained how 15% of a building’s heat is lost at the junction between the wall and the floor. The firm’s load-bearing thermal insulation blocks, Thermoblock (pictured), can be placed in this tricky area to reduce heat loss to just 1%.
More energy-saving products were on display at the XO stand, including its solar roof tiles (pictured), which can replace traditional roof tiles. The tiles cover more of the roof’s surface in solar than conventional panels, creating even more clean energy than usual.
Meanwhile, Zypho showed off its shower unit, which recovers heat from waste water, improving the efficiency of the shower by 30-75%.
