Abstract: This interdisciplinary study proposes practical modifications for achieving net-zero energy building (net ZEB) in historical churches while all the values of the church have been recognised and preserved. The church is studied from structural, mechanical and electrical perspectives. A 40.7% rise in energy efficiency and a 12% rise in exergy efficiency are observed after applying modifications. The concept of net ZEB has been accomplished in the church. A 98% balance in annual energy exchange is reached between the on-site and the utility grid power generation by applying the net metering method.

Keywords: energy retrofit; PV system; net zero energy building; net ZEB; net metering; sustainability; horizontal air curtain; exergy analysis.
