Description
The present paper studies the thermal and energy performance and potential adaptive reuse of the lost underground bunkers of Kukës, Albania. The approach is exemplified using a 150-m long cross-section of the underground network selected for the parametric computational simulations. Data regarding local climate, design typology, and building materials is used to generate a finite-element simulation model of the underground tunnels. Different scenarios including insulation of the outer walls, occupancy patterns, and ventilation regimes are tested. The results show that indoor air temperature ranges from 15-18°C during winter and 23-28°C during summer. During January, the temperatures are higher by 3-5 ᵒC in comparison to the same structure and scenarios located above ground, whilst during July they are 5-8 ᵒC lower. Insulation does not affect the heat flux through the outer walls. The average energy consumption oscillates around 55 KWh.m-2.a-1forbase case and 98-230 KWh.m-2.a-1fordesign scenarios. The results establish the same building consumes44-145%more energy when located above ground as opposed to underground.
