Abstract
Green roofs are generally applied to concrete roofed buildings. This study compares the thermal performance of green roofs that occur in corrugated concrete and zinc to expand green roof innovation. The study experimented on a method using the 2011 Ecotect computer simulation. The results showed that the difference in temperature reduction in corrugated zinc was higher than in concrete. Changes in heat outside the roof space on both have a number that has a relatively small difference, but the difference in heat is visible in the inner space. Based on the thermal performance of the roof, the use of corrugated zinc roofs as the base of the green roof in the building could be an alternative green roof material besides concrete.
Highlights
Drawn on the tendency of green roof research at least two aspects dominate the focus of green roof research on a world scale, i.e., the criteria for building objects and determining research methods
Based on practical considerations of the model and data processing process, this study focuses on the thermal performance of green roofs made of concrete and corrugated zinc using Ecotect 2011 simulations
Calculation in buildings without plants obtained the value of Overall Thermal Transfer Value (OTTV) in Table 2 with the results compared to the energy efficiency benchmarks
Summary
Drawn on the tendency of green roof research at least two aspects dominate the focus of green roof research on a world scale, i.e., the criteria for building objects and determining research methods. Green roof research trends are influenced more by environmental and energy issues. This research attempts to expand the scientific discourse of architecture by comparing the materials used for green roofs with residential building objects. The first tendency, the object of green roof research is often the focus of research on concrete roofed buildings. Concrete green roof research generally deals with commercial public buildings, such as hotels, malls, superblocks, or schools. This study presents an innovative green roof placed on the roof of a low-rise residential building with a location criterion of a high-density residential area in a tropical climate
