Dora’s Varnava House

Client: Dora Varnava
Size: 125 m²
Building type: Single story residence
Project description:
This single story house in Athienou, Larnaca was constructed in the late 1940s with adobe masonry walls and timber rood structure. The extended deterioration due to the weathering effects and the lack of proper maintenance necessitated the structural retrofit and the refurbishment of the structure. The upgrade of its energy performance was mandatory, due to the relatively high operational costs. The roof’s structure was reconstructed, thermally insulated with extruded polystyrene boards and waterproofed with polyester film. The windows and the doors were replaced with new ones, consisting of PVC frame, low-emissivity dual glass and exterior shading system. The walls’ plaster was removed and lower thermal conductivity plaster was applied, while no extra insulation layer was added due to the space limitations. A central heating system with high COP liquid petroleum gas (LPG) boiler was installed, whereas the cooling is provided by split units. The hot water is primarily supplied by a solar panel system with horizontal water cylinder and insulated piping installed on the roof, while an auxiliary system connected with the central heating was also implemented. The selection of the materials, the methodology of the energy performance upgrade and the consequent construction activities were carried out with particular cautiousness in order to minimize the effects on the building’s architectural character.
