All new Government buildings are required to be net zero carbon in operation, but when it comes to refurbishment or retrofit the route to net zero carbon is less clear. There is a requirement to set a route map to net zero carbon by 2050, but how is this best achieved? There is a clear direction in that fossil fuel boilers must be replaced by electric heat pumps, but the issues around capital cost, internal emitter upgrades, embodied carbon and lifecycle carbon associate with envelope upgrades, are complex. The strategy of Fabric First with heat pumps, is not always going to be the right solution due to the upfront carbon and high capital / operation costs. At Cundall, we have undertaken R&D that is helping steer us towards an optimum approach, which has some surprising answers - things are not always as clear cut as they seem!

What we will cover:

· What envelop upgrades should be prioritised to achieve returns in terms of capital cost and embodied carbon.

· What are the alternatives solutions to heat pumps both as an intermediate step and long term step to net zero carbon.

· What impact will the electrification of the MOD estate have on the electrical infrastructure and how can the alternative solutions reduce the need for electrical reinforcement.
