The La Serrezuela roof designed by CIDELSA is an bioclimatic solution adaptable to extreme tropical conditions. Its thermoplastic and color characteristics guarantee a thermoplastic thermal performance (low conductivity, high reflectivity and low emissivity) that contributes to the thermal comfort. According to monitoring results, once the work is finished:
- In the surface temperature, the PVC textile covering presented 37.6° C under conditions of high solar radiation and outdor temperatures higher than 32 ° C.
- The temperature of the interior face registered 33.1° C, meaning a reduction of 4.5 ° C with respect to the register of the exterior face, definitely affecting the internal comfort conditions based on the effect of radiant temperature from the roof.
- In relation to the double-deck system with an air cushion and the ventilation by thermal and dynamic effect of lower openings, a final operating temperature of 29° C is achieved, which is within the adaptive comfort range under the conditions of Cartagena.
According to the results of the analysis, the Cidelsa’s double-layer system decission is justified, since energy savings are 100% in relation to the use of HVCA, guaranteeing thermal comfort, natural lighting and compliance with the requirements of bioclimatic design at the same time.
