A closer look at the UK's sustainable building and renewable energy targets

The United Kingdom (UK) has set ambitious targets to combat climate change and promote sustainable development. One of the key areas where the UK is focusing its efforts is in the building and renewable energy sectors. In this blog post, I’ll be taking a closer look at the UK's sustainable building and renewable energy targets, their purpose, and how they compare to the targets set by other European countries.

Sustainable building and renewable energy targets


The UK has set a target to achieve net-zero carbon emissions by 2050. As part of this goal, the UK government has set specific targets for sustainable building. The primary target is for all new homes to be built to zero-carbon standards by 2025. Additionally, the government has set a target for all existing buildings to be retrofitted to improve energy efficiency by 2030.


As well as sustainable building targets, the UK has also set ambitious renewable energy targets, including the aim to generate 40% of its electricity from renewable sources by 2030.


The purpose of these targets is to reduce carbon emissions and promote sustainable development. By building new homes to zero-carbon standards and retrofitting existing buildings, the UK can significantly reduce its carbon footprint. These targets will also create new jobs and stimulate economic growth in the building sector.


In comparison with other European countries


The UK's sustainable building and renewable energy targets are among the most ambitious in Europe, and the UK currently ranks 6th in the world for wind and solar production and use. Several other European countries have set even more ambitious targets. For example, Sweden has a target to achieve net-zero emissions by 2045, while Denmark has a target to generate 100% of its electricity from renewable sources by 2030.


Who is doing particularly well?


Several countries in Europe are leading the way in sustainable building and renewable energy. Norway, for example, has achieved nearly 100% of its electricity generation from renewable sources, namely hydroelectricity. Denmark and Germany are also making significant progress, with over 60% and 40% of their electricity generated from renewable wind and solar sources, respectively.


From a Mesh point of view, how are we doing? Can we meet these targets?



Mesh, a UK-based sustainability consultancy, is committed to helping its clients meet the UK's sustainable building and renewable energy targets. While the targets are ambitious, Mesh believes that they are achievable with the right approach. Mesh works with clients to identify opportunities to improve energy efficiency and reduce carbon emissions. Mesh also helps clients to implement renewable energy solutions, such as heat pumps, solar panels, batteries and many other low carbon technologies.

What must be done in the building and renewable energy sector to help meet these targets?


To meet the UK's sustainable building and renewable energy targets, significant investment will be required in the building and renewable energy sectors. The government must provide incentives for businesses and individuals to invest in sustainable building and renewable energy solutions. The construction industry must also adopt new technologies and practices to improve energy efficiency and reduce carbon emissions.


In addition, much work needs to be done at grass-roots level to help building design teams to collaborate better, work with powerful and insightful software and encourage as well as educate the next generation of architects and building consultants graduating from college and university.

Only through this long-term commitment can we make lasting and positive change.


How does the work that Mesh do contribute to meeting these targets?


Mesh is making a significant contribution to meeting the UK's sustainable building and renewable energy targets. We work with clients at the earliest possible stages to understand sustainable aspirations, compliance requirements and identify unique project opportunities to improve energy efficiency and reduce carbon emissions. Much of our time is spent at early project stages, understanding the fundamental thermal and wider building performance behaviour to ensure that the developed design is informed and impactful.


We bring experience, software, collaborative thinking and never-before seen insight to designing buildings fit for the future.

In conclusion, the UK's sustainable building and renewable energy targets have been set to ensure the UK plays its part in the global push to reduce, stop and reverse the damage that carbon emissions have had on our world. The UK are doing ‘ok’ at the moment, but it can definitely do better, and Mesh will continue to play a pivotal role in decarbonising the built environment in the UK and beyond.

Building performance specialist Mesh has completed a building services design project for a new flagship art gallery in Savile Row – Sadie Coles HQ. The six-storey Grade II listed Georgian townhouse in London’s Mayfair, which dates back to the 1730s, has been fully restored and transformed by lead contractor Work Ltd, to create a unique space for contemporary art. The building, once home to the Burlington Fine Arts Club in the 19th century, had been bomb damaged in World War II and used as offices post-war. It has now been sensitively reinstated as a space for artists to exhibit their work in a part of London which has a long association with contemporary art. The key aim of this extensive refurbishment project was to work to a fast-track programme for the gallery’s opening to coincide with the Frieze Art Fair. Mesh was appointed to develop a holistic MEP building services strategy, from concept through to detailed design, and in keeping with the character and constraints of this heritage building. Enhanced control of the internal environment was required to maintain visitor comfort all year round and in the context of continually fluctuating occupancy levels, including events for up to 200 people. Working within a Grade II listed building required a highly considered approach at every stage – historic architectural features were revealed and restored internally and externally, and extensive structural improvements were required to accommodate art loadings. These factors had to be reflected in the services design and specification. Mesh used dynamic thermal modelling for different scenarios of use to understand the heating and cooling loads required and to allow the services to be accurately sized for each room or gallery. Two priorities were cooling and for each area to be individually controlled according to occupancy levels. Discrete but robust heating and cooling provision was designed for the gallery areas and the MEP services were concealed in void spaces to avoid impacting on the architectural features of the building or the layout of the galleries. Plant and equipment had to be sited in compliance with stringent planning requirements, which limited the number, size, position and visual impact of the external units. Passive measures were introduced to reduce energy consumption and included actuated openable rooflights in a glazed lantern to purge warm air during the day and reduce the reliance on the active cooling system. Giles Reid, Giles Reid Architects: “The new gallery has succeeded in its ambition – to reaffirm that London has an important position in the global art world. This was a complex project which had to be delivered in just nine months from planning approval for the fixed deadline for opening, and despite having to carry out extensive structural alterations. The building is performing well from a services perspective, including at the opening event which was attended by around 800 guests. The M&E design in contemporary art spaces like this must never detract, visually or acoustically, from the art being exhibited and this has been successfully achieved. This is a fantastic statement building which has been acclaimed and the Client is thrilled. It is a credit to everyone involved that this historic building has been brought back into use for contemporary art.” Doug Johnson, Founding Director of Mesh: “This project demonstrates exactly what intelligent building services engineering should deliver – an integrated, high-performance solution to deliver year-round-comfort for visitors and users of the building whilst maintaining a clean aesthetic. Working within a Grade II listed building with complex planning restrictions required genuinely creative engineering rather than a conventional response. We are really proud to have contributed to this outstanding building transformation.” The Project Team: Client: Sadie Coles HQ Lead contractor (design and delivery): Work Ltd Architectural partner: Giles Reid Architects MEP design / building performance: Mesh About Mesh Mesh offers a range of design and engineering services to help organisations in the public and private sectors to improve the energy efficiency of new and existing buildings, housing and estates.
