Making the most the net zero architectural transformation in the construction industry

[edit] Net-zero architecture is transforming the construction industry, how you can make the most of it...

Despite the scope of these intentions, a change of this magnitude still requires a shift in how the construction industry as a whole operates. Whilst we are still a long way from reaching these targets, however, the industry certainly looks to be moving in the right direction. From incorporating new and innovative design features such as green roofing, to minimising wastage, and more, there are no shortage in the availability of solutions that are working towards the transition to a net-zero economy.

[edit] What is net-zero architecture?

In order to be classed as net-zero, a building has to be able to counterbalance any carbon emissions produced throughout its lifetime. This not only includes the embodied carbon produced throughout the construction phase, but also throughout its entire lifespan, and

of course, its demolition. This means that just trying to minimise carbon dioxide production throughout the construction phase will likely not be enough. Any excess emissions will also have to be offset with innovative designs and sustainable technologies to the point where more carbon is absorbed than is released into the atmosphere.

[edit] Efficient energy usage

Regardless of whether you intend to power the building through solar panels, or tap into geothermal pockets
with a heat pump, the first point of call prior to these implementations should always be to ensure the building is running at optimal efficiency, and that the design minimises unnecessary energy usage. One of the most effective ways of doing this is by reinvigorating existing insulation within the walls, floors and ceilings. Not only does this improve heat retention throughout the winter, but also keep it cooler throughout the warmer parts of the year – significantly reducing the need for non-renewably powered heaters and air conditioners.

[edit] Renewable energy sources

Once assuring optimal efficiency, additional renewable technologies can then be incorporated. More often than not, this will include solar panels – the UK’s most common renewable energy source – with a typical home system saving over a tonne of carbon dioxide each year. With approximately 85% of UK homes heated predominately by gas, however, achieving carbon neutrality in this area remains a challenge. Fortunately, the installation of gas boilers into new homes is banned from 2025 onwards, leaving low-carbon heating sources such as ground source heat pumps (GSHPs) as the most preferable solution.

Despite being used since the dawn of man, another renewable heating source which has returned in popularity is biomass – where wood, plants, and other organic matter is burned to heat homes, or is connected to central heating and hot water systems to fuel the entire building’s heating requirements. As the burning of this plant matter produces less carbon than what is absorbed throughout its lifespan, assuming that new seeds and saplings are planted in their place, biomass burning can be an entirely sustainable energy source.

[edit] Optimal orientation

Whilst it is easy to get distracted by all the latest sustainable tech, it is often the simplest changes which prove to have the greatest impact. Regardless of what you are looking to install, if you want to ensure these devices are operating at the greatest efficiency, then the orientation of the building is key in minimising excess energy usage. Solar panels, for example, operate more efficiently when facing south. You are also going to want to take other factors such as natural shade and lighting into account, as both can have a considerable influence on energy usage. Lighting, for example, accounts for between 17% and 20% of a home’s total energy consumption. These figures can be cut significantly be addressing this within the design stage, taking the building one step closer towards net-zero.

[edit] How can you benefit beyond net-zero architecture’s environmental impact?

The relationship between carbon emissions from the construction industry and global warming is no secret. Whilst the objective of transitioning towards a net-zero economy should always be its ecological impact, early adoption of these sustainable technologies and techniques enables businesses to gain a significant competitive advantage as regulatory bodies begin to become more demanding in their commitments towards net-zero.

The market for green building is only on the up and is expected to reach a value of $563.91 billion by 2027. For businesses already investing in sustainability training or renewable energy technology installation, for example, you will be spared the unexpected time and costs which tighter legislation would otherwise impose upon you, all whilst being able to highlight your extensive experience in sustainable construction. Whether you showcase this distinctively on your website, plaster it all over your social media channels, or reach out across the industry directly, positioning yourself as an industry leader in sustainable construction looks to be crucial for the decades to come.
