INCA Case Study: May And Gunnet Court, Edinburgh
Project Type: Refurbishment
This project showcases the remarkable achievements in the thermally upgrading of the May and Gunnet high-rise buildings located in a picturesque coastal town on the east coast of Scotland. This project was commissioned with the objective of reducing heating costs for tenants while simultaneously enhancing the aesthetics and fostering a stronger sense of community within the area and create an environment that instilled a sense of belonging.
The May and Gunnet buildings presented a unique set of challenges and technical complexities, with diverse substrates ranging from cavity walls with smooth brick to rendered gables, bison concrete panels, and Wimpy No Fines. To overcome these intricacies, a detailed approach was implemented, taking into consideration various elements such as soffits, balconies, internal walkways, stairways, and the interface with a curtain walling system that was not being replaced. Furthermore, the project involved working around numerous conduits, as well as gas and electric pipes running along the soffits of the walkways, adding to the complexity.
In the face of challenging weather conditions prevalent in the region, the choice of a system that could withstand the elements was of paramount importance. The choice for this project was the Soltherm Endurance S75 system, renowned for its ability to withstand the harshest conditions. This system utilised Cross Knot fixings to ensure stability and strength, while Soltherm Clamping Rings provided a specific fixing pattern capable of withstanding high wind loads. With an indestructible façade, the Endurance system offers exceptional impact resistance and an impressive effective lifespan of 75 years, making it the ideal solution for this ambitious undertaking.
The partnership between Soltherm and A C Whytes proved instrumental in the success of the project. Our collaboration showcased a shared commitment to delivering exceptional thermal upgrades while prioritising aesthetics and community development. The dedication to excellence and technical expertise sets us apart in the industry, ensuring that customers received outstanding results that exceeded expectations.
Understanding the importance of minimising disruption to tenants, a strategic sequence of works was meticulously devised. This ensured a seamless process from start to finish, allowing the tenants to continue their daily lives with minimal interference. Accurate attention to detail extends to the walkways, where a unique thermally isolated trunking mechanism was implemented, effectively eliminating any thermal bridging concerns. Additionally, the concrete balconies have been insulated on both their soffit and front faces, successfully mitigating the risks of cold bridging and condensation buildup.
To take the thermal efficiency of the buildings to the next level and meet the desired U-value requirements, over 4000m2 of External Wall Insulation (EWI) with varying thicknesses was installed. This cutting-edge installation has achieved remarkable U-values of 0.21 and 0.25, surpassing energy efficiency targets. Furthermore, as part of the comprehensive renovation approach, all windows, doors, and roofing have been replaced. The balconies and walkways have received a resurfacing treatment, ensuring their longevity and enhancing visual appeal. Additionally, street furniture in the vicinity was thoughtfully adapted to harmonise with the overall visual, resulting in a cohesive and aesthetically pleasing environment that the tenants could take pride in.
Undoubtedly, the thermal upgrading of the May and Gunnet residential high-rise buildings presented numerous technical challenges, weather-related complications, and logistic difficulties. However, through the accurate selection of appropriate systems and materials, strategic planning, and diligent execution, the project successfully achieved its objectives. The result is a community that benefits from reduced heating costs, improved energy efficiency, enhanced visual appeal, and a renewed sense of pride in their surroundings. The May and Gunnet buildings now stand as symbols of resilience and transformation, testaments to the power of collaborative efforts to create a better, more sustainable future for all.
