Experimental investigation of a metal sheet roof for a school building in developing countries in tropical climates

Popis výsledku v původním jazyce

One of the key problems with buildings in tropical climates is the overheating of interior spaces due to an inappropriate building envelope. In the design of a school building in Zambia, possible roof assembly variants were assessed to find their thermal performance under real boundary conditions. For this purpose, a thermally insulated test box was built on the roof of the CTU university. In this way, six roof samples can be measured simultaneously in one test run. The roof assembly, made of a pure steel sheet with Zn coating, was considered to be the reference case. This case was then modified step-by-step for either a colour change, adding additional material layers, or ventilating a 2 cm thick air cavity. Reed boards were used as thermal insulation and unburnt earth boards served as the heat storage layers. In total, 18 roof assemblies were tested in three consecutive test runs (three-week periods between June and November 2020). The white paint and ventilated air cavity were proven to be the most effective solutions for reducing the heat gain through the roof. One roof assembly was selected for use in the school building project.
