On a job, heat is often the item that weighs heaviest in the carbon footprint. When a neighbourhood is supplied by a network, your role is to check what's actually behind the substation and steer the client towards the right settings, at the right time. Wood energy, heat recovery, geothermal, gas top-up — the mix is evolving fast and it's changing how you size, balance, and control an installation. By understanding the sources used and their constraints, you secure performance and gain credibility when questions about decarbonisation come up.

With a clear method, you secure the job and gain comfort, without a bad surprise at handover.

On site, a green roof can become your ally for improving summer comfort and smoothing out temperature swings, without adding complexity in use. It also helps you better manage rainfall, retaining some of the water and limiting runoff peaks to the drains. If you frame it correctly from the start (load-bearing capacity, waterproofing, root protection and maintenance), you deliver a clean, durable solution that's easy to explain to the client.
