## Summary

The Horniman Public Museum and Public Park Trust is spearheading a major decarbonisation project within the iconic Horniman Gardens in London, UK. The initiative, focused on the Centre for Understanding the Environment (CUE) and the Butterfly House, is part of the museum's commitment to achieving Greenhouse Gas Neutrality by 2040. The procurement process for this project, titled "CUE & Butterfly House Decarbonisation," is currently in the tender update stage. Key dates include the submission deadline for expressions of interest by 10th April 2026, the enquiry period closing on 5th April 2026, and the award period ending on 14th August 2026. Pringle Richards Sharratt Limited, the project architects and M&E designers, along with the museum trust, are collaborating in this competitive flexible procedure, with an estimated value of £900,000 and implemented through a selective procurement method.

This project presents significant business growth opportunities, particularly for firms specialising in sustainable construction, HVAC systems, and thermal performance technologies. Companies with expertise in installation services of electrical and mechanical equipment, as well as those experienced in working with listed or heritage sites, will find this tender particularly promising. The selective procurement approach allows for small and medium enterprises (SMEs) and voluntary community and social enterprises (VCSEs) to compete effectively, with a focus on price and quality. The tender evaluation prioritises 60% on cost and 40% on quality, making it accessible for entities demonstrating relevant experience, strong financial standing, and innovative solutions in decarbonisation projects.

## Notice

The Butterfly House and Centre for Understanding the Environment (CUE) are located within the wider Horniman Gardens site, which is a Grade II listed Park and Garden. The CUE was constructed in 1995 and was originally intended as a temporary structure with an expected lifespan of 20 years. The Butterfly House was constructed in 2016 as glasshouse for tropical plants and butterflies. The Horniman wish to engage a Main Contractor who will manage and deliver the implementation of the decarbonisation of the above buildings in the listed setting. The works will be let on the basis of traditional JCT contract intermediate form without quantities, but with some contractor design elements. As part of the Horniman's Climate and Ecology Manifesto we have made a commitment to become Greenhouse Gas Neutral by 2040. The key objective of this project is to move us towards this goal by doing the following: * Butterfly House: Replacing the gas cabinet air heater with air-to-air Air Source Heat Pumps (ASHPs). * Butterfly House: Thermal performance and air tightness improvement by replacing existing glass and acrylic with triple layer polycarbonate cladding to existing steel structure with new aluminum glazing bars, window and vents. * Butterfly House: Thermal performance and carbon reduction by installation of new trench heating with new Air Handling Unit and visitor path surface or as an alternative an fan-coil system * CUE: Replacing the gas boiler in the Centre for Understanding the Environment (CUE) building with air-to-water Air Source Heat Pumps. * CUE: Improve the thermal performance and air tightness improvement by draught proofing and thermal bridge mitigation including floor, wall and roof new thermal insulation. * CUE: Install Mechanical Ventilation Heat Recovery (MVHR) * Upgrading the electrical cables inside both the Butterfly House and CUE building.
