In the race to reach net-zero by 2030, we’ve seen the built environment undergo some significant changes. But with the sector currently responsible for almost 40% of all greenhouse gas emissions, are we on track to meet this ambitious target? This article looks at how we can build more sustainably.
Embodied carbon in roofing
Working with materials that emit the lowest carbon intensity and have an overall better impact on the environment is one way in which the construction industry can significantly reduce its carbon footprint.
“Embodied carbon” refers to the level of carbon produced during the making of a material, taking into consideration the process of extraction, transportation and manufacturing of the end product.
This green roofing approach can be implemented with new builds and refurbishments, offering a great opportunity to drive positive change in the sector.
In addition to sustainable materials, longevity is a key factor in reducing embodied carbon as it ensures the building maintains its waterproofing and thermal integrity. It also mitigates the chances of the roof needing refurbishment after a short period.
Zero-carbon housing developments
Plans to launch the UK’s first homes with zero energy bills have been announced by Octopus Energy, who are collaborating with housing company Ilke Homes to deliver the initiative.
The houses will generate their own clean energy; complete with solar panels, battery storage and air source heat pumps. With the first few houses already on the market, the business duo hopes to roll out more than 10,000 homes by 2030.
We’ve seen similar builds across London, as the demand for eco-housing continues to rise in popularity amongst buyers.
Mandatory WLC assessments for buildings
Back in May 2022, a committee of MPs called for the mandatory requirement for buildings with more than 10 homes to undergo a whole-life carbon assessment. The evaluation would take into consideration the carbon emissions from the building over its entire lifetime; from its construction, through to its disposal.
At the moment there is no policy in place that requires embodied carbon emissions from buildings to be monitored or controlled.
The report further outlined that the requirement should be established in building regulations and included in national planning policies. Local councils have also been urged to include the carbon initiative within their local plan.
It was recommended that this regulation be introduced no later than December 2023 but we are yet to receive updates on the timeframe.
As professionals in the built environment, it is our responsibility to promote sustainable change and Pillar Partnership looks forward to seeing further innovations within the sector. However, it is clear there is still work to be done if we want to reach net-zero by 2030 - this is only the start.
