Technical Study of a Reinforced Concrete Building with Thermal Analysis of Utility Systems

Abstract

This study examines a four-storey reinforced concrete building intended for residential use, located in the city of Tlemcen and classified as being in a seismic zone III. The design was carried out in accordance with the Algerian seismic regulations RPA2024. To achieve this, we must carry out a detailed analysis to understand the building, taking into account the various factors affecting this structure in terms of the loads it is subjected to and other factors. In Algeria, buildings are characterised by low energy efficiency, making them a major consumer of energy, particularly as the housing sector is not subject to strict regulations in this area. To determine the amount of heat loss and gain, as well as the annual heating requirements of the dwelling, we used the ‘CYBE’ calculation programme. This programme provides a description of the dwelling and its fittings, estimates energy consumption, and verifies the dwelling’s compliance with DTR C3.2 and DTR C3.4 standards. The factors taken into account included: heating, cooling, wall composition and orientation, windows, local climate, and insulation. The software also provides advice and solutions for reducing energy consumption, alongside recommendations for improving energy efficiency, enhancing the building’s performance, and ensuring thermal comfort within the home.
