This is particularly important for projects involving decarbonisation or net zero refurbishment where the primary aim is to modify the building environment, ensuring more efficient energy management. This can have a direct and significant impact, not just on sensitive organs, but also on other vulnerable artefacts, such as pianos and art works. Therefore, it is important that the vulnerabilities of the organ are understood by the design team and considered during the project development process. This may require understanding how insulation could be used to provide better buffering between the organ space and the exterior of the building, how heating could be managed to minimise damaging effects on the instrument, or simply how door operations could be managed to avoid ingress of cold, dry external air having an immediate effect on the tuning of the organ. Organs are complex instruments with numerous interconnected parts that are sensitive to environmental factors and perfect control is often very hard to achieve in a large and complex historic building. However, if the basic effects of environment on the organ are understood, then simple management practices can be put in place to minimise the most common types of deterioration.
