Priority Schools


Contractors are required to use the K²n iSERV methodology to automatically monitor and report on the energy and water use of the School. The resources needed to do this can be found here. Guidance for Contractors on use of the iSERV/K²n National Database for continuous monitoring and benchmarking of ESFA capital projects can be found in the Guidance Document.


For more details, the suite of documents and tools which form part B of the requirements for school building projects are listed below. The sections show the parts of the ESFA documents where a contractor is required to undertake energy monitoring using the iSERV methodology and the K²n Platform.

The full ESFA Part B documents link can found at: The ESFA School Building documents.
