Gabrovo Municipality had been trying to renovate St. Cyril and Methodius school for more than 5 years. The municipality faced a number of challenges in their ambition to renovate the building to a much higher energy efficiency standard. The building of St. Cyril and Methodius school in Gabrovo was constructed in 1970. The building consists of four blocks (one administrative; two containing classrooms and one sports facility). The heating is sourced from natural gas boilers and the building contains no cooling and ventilation systems.
The tender used a Performance/Output Based Specification approach for minimum energy efficiency - class B and is the first tender in Bulgaria to specify achievement of a minimum energy class. There were measures to limit the water consumption and also for ensuring a healthy environment in the rooms via Automatically Controlled Valves.
Numerous informal meetings between different stakeholders - the energy auditors, municipal and EcoEnergy experts took place. As part of the research into what was possible for the procurement, two companies participated in one of the Bulgarian SPP network meetings, clarifying the benefits of building automation. In addition, individual meetings with four different companies involved in building automation systems were held during the development of the tender specifications.
