Combining Traditional Building Systems with Contemporary Technology: The case of “Archontikon” in Akaki village, Nicosia

Short description of what will be presented during the seminar:

Traditional construction methods in the lowland regions of Cyprus are predominantly defined by the use of load-bearing walls constructed from stone and mud bricks, complemented by flat roofs supported by wooden beams. In the current context, where the reduction of the energy footprint of buildings, the optimisation of bioclimatic function and the incorporation of sustainable materials are of paramount importance, there is a concerted effort to revive the construction principles inherent in these historical building systems, now enhanced by contemporary technological advancements.

One notable initiative is the construction of the “Archontikon” on the periphery of Akaki village in Nicosia. The “Archontikon” (meaning “Mansion”) is an auxiliary building adjacent to the Church of Ayios Iakovos Tsalikis, which is presently under construction. This single-storey structure is characterised by load-bearing walls that are composed of stone at the base and mud bricks at the upper section.

Slightly processed natural materials were extensively used in the structure, including local stones, handmade mud bricks, wood, traditional coatings and mineral wool. To a much lesser extent, contemporary materials such as steel sections, concrete and damp-proof breathable membranes were also incorporated.

The inner surface of the shell’s walls was designed to include a narrow, naturally ventilated space, which accommodates thermal mineral-wool insulation panels and all necessary electro-mechanical installations. This lightweight structure was coated with traditional plaster applied to a metal mesh that is affixed to a wooden frame. Furthermore, four windows located at the uppermost section of the hall primarily facilitate the natural extraction of hot air, thereby contributing to the cooling of the hall during the summer period.

The energy footprint of the structure is significantly lower than that of a comparable conventional structure. Its exceptional energy efficiency is attributed to the incorporation of both thermal insulation layers and the thermal capacity of the walls. Furthermore, 60% of the total volume of construction materials, including the foundation slab, is fully recyclable, while this figure increases to 90% when the foundation slab is excluded.
