Mesh Energy: Our B Corp Journey - Part 1

Welcome to the first in a series of posts about our journey to becoming a Certified B Corporation which we'll be publishing over the coming weeks.


Also - hi! We know we've been away from our blog for a while. We've been busy focusing on other areas of the business, such as growing Meshwork, but it's good to be back and we're excited about sharing loads more great educational and inspiring content with you. If you have any questions about becoming a B Corp or anything else - please don't hesitate to reach out!


What is B Corp Certification?

B Corp Certification is a designation that a business is meeting high standards of verified performance, accountability, and transparency on factors ranging from employee benefits and charitable giving right through to supply chain practices.


In order to achieve certification, a company must: demonstrate high social and environmental performance; make a legal commitment by changing their corporate governance structure to be accountable to all stakeholders, not just shareholders; and exhibit transparency by allowing information about their performance measured against B Lab’s standards to be publicly available on their B Corp profile on B Lab’s website.


Certification is acquired through a points-based assessment and the pass mark for certification is 80 points.

Why did we decide to go for our B Corp Certification?

Originally, we started out by looking at British ISO Standards to formalise our business processes and sustainability. However, as a service provider we didn’t feel like we had an affinity with the accreditation process.


Around the same time, our marketing partners Avery & Brown mentioned a more holistic approach to us - B Corporation accreditation. My colleague Rhiannon James and I reviewed this further and thought it sat really well with the overall ethos of Mesh. So we went for it!

The process! What did we do, how long did it take, and how much did it cost?

We started the process in November 2020 and it took us 12 months from the time we showed initial interest and lodged our application to when we were initially certified in November 2021.


The first stage was going through a questionnaire across a diverse range of business areas. This stage is completely free to answer and submit. However, once complete and submitted it all went quiet! It took eight months for B Corp UK to pick the application up and come back to us in September 2021 to properly start the review process.  This then only took a couple of months.


To make our lives easier when the application was looked at in September, we had already dug out all of the documentation requested to prove our answers. This no doubt made the final review process as painless as possible. Example documents included energy bills, client and staff engagement surveys, modified articles of association, company accounts, evidence of charitable work and donations, etc. Top tip - getting all of this in order in good time will really help you out!


As far as costs go… final certification was £1,000 +VAT. Review and reaccreditation happens every three years.

So, Mesh is a B Corp. What does it mean to us and how did we score?

Personally, I found that the deeper the team and I delved into the accreditation process, the more we realised we had made the right decision. As a team-focused (and subsequently customer-focused) service-based business, the recognition of transparency, employee engagement, diversity, community engagement and customer stewardship is a potent mix. As cynical as we can all get about paying for accreditations (and the abuse of them), the B Corp framework and how we have scored against it will very much be used to chart our company’s progress over the coming years.


And what was our score? As I said above, the minimum threshold to qualify for B Corporation status is 80 points and we came well in at over 98. The maximum available points is 140, so we have some way to go. But for a first effort and for a relatively small business we are really chuffed to have punched well above our weight.


Onwards and upwards!


My next B Corp post will take a more detailed look at the scoring methodology. Keep an eye out for it!

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.
