Lefkonos 2-12, 1011 Nicosia

Katharis Primary School - Dimitris Lipertis is one of the 25 school buildings selected by the European project PEDIA (Promoting Energy efficiency & Developing Innovative Approaches in schools) to upgrade their energy efficiency to the level of a Nearly Zero Energy Building (NZEB).

Through the Cohesion Policy Programme, “THALYA 2021-2027”, and the project “Creating Zero Energy Schools", the construction part of the energy upgrade was co-financed, while the part related to technical support was financed by the PEDIA project, of the European Union's PDA (Project Development Assistance) program, Horizon 2020.

Announcement number: Fourth

Energy upgrade cost: €571,800.00

Implementation period: September 2024 – May 2025

Contracting company: HOUSEMASTERS Ltd.

Project engineers: Cyprus Energy Office Engineering Team

External partners:

  • Study Safety & Health Coordinator: YNB Consulting Ltd

Challenges identified during on-site technical visits:

  • Very low energy efficiency of existing installations
  • Old-style windows and doors with single glazing
  • Non-thermal comfort for school building users
  • Increased operating costs for energy needs
  • Lack of thermal insulation of walls and ceilings
  • Inadequate control of natural ventilation
  • Rising damp & Humidity on ceilings
  • Older energy-intensive types of lighting

Energy interventions required for the building in question:

  • Replacement of existing frames (new thermally insulated windows and doors)
  • Replacement of existing lighting with new LED fixtures
  • Damage/moisture repair and surface painting works
  • Replacement of existing ventilators
  • Roof insulation and waterproofing
  • Shell thermal insulation

Benefits from the energy upgrade of this building:

  • Reduced energy consumption (electricity and heating oil)
  • Improved indoor air quality
  • School becomes a place of experiential education
  • The school is an example of a sustainable school
  • Thermal comfort in indoor spaces

Actual results after upgrading the building in question:

  • 61% energy savings
  • 61% CO2 emissions savings
