Nouvelle Souidania, Algeria

Cité Nouvelle Souidania

The main purpose of this project is to build a pilot rural house with three bedrooms, one kitchen, and one bathroom. All of the housing is on the ground level. The energy concept to be followed in this project is based on an integrated approach with a special emphasis on passive techniques such as: • An optimal orientation • The use of natural light • Thermal insulation of the envelope • Use of summer shading • Use of double glazed windows • Natural ventilation in summer

Description

The project will be located near Algiers within the CNERIB site. This rural house will be a one-family house with an area of 80m² and a total volume of 180m³.

Solar energy

Water heater system

Primary water heater system
Solar Thermal collector on the roof
Description
Domestic hot water will be supplied by solar heating system. Collectors will be installed on the roof of the building and the solar tank and controls will be installed near by. The solar collectors should satisfy the demand for heating and DHW with 80%.

Shading devices

Type of shading system installed
Static (fix) shading systems as part of the building architecture (e.g. Maschrabiyya, porch roofs, pergolas)
