Energy efficient design optimization of a bioclimatic house

Abstract

The global energy context of the year 2018 makes us pessimistic about the future. The geopolitical, environmental and socio-economic aspects are linked to the political tensions of countries that hold and manipulate the global energy market. These countries are haunted by the population growth, the depletion of fossil resources and the global economic crisis. Each country is trying to find reasonable solutions to deal with this crisis. Unfortunately, these solutions always have direct negative repercussions on the population and on the environment. In this paper we present a case study developed in Algeria and inspired by the current and critical socio-economic situation of the country, in particular, the application of energy-saving techniques to an existing building. The investigation was conducted by using both simulation software and real interventions. We analyse some of the major components, such as building’s orientation and exposure to daylight which have significant impact on energy consumption. We present the concept of Building Performance Simulation Analysis, using Autodesk ECOTECT Analysis and COMSOL Multiphysics software, and give full consideration to various ecological energy-saving methods. Using our models, we present a possible solution for retrofitting a building to minimize its energy consumption. The results are useful for both building energy conversation and creating a comfortable living environment in future.

The impact of climate change on the thermal-energy performance of the SCIP and ICF wall systems for social housing in Brazil

“…Hacene et al. 53 identified that adding a layer of 5 cm of polystyrene in the walls is the lowest-cost solution to reduce energy consumption while guaranteeing thermal comfort in Algeria.…”

“…Mahar et al 52 studied the thermal comfort in reinforced concrete frame houses using mineral fibre as insulation in Quetta, Pakistan, and the results indicated that comfort hours can be increased up to 60%.

Renewable Energy in Algeria: Desire and Possibilities

“…Figure 6 shows the Tlemcen house’s use of natural gas and electricity usage throughout the year. Natural gas represents 75% of the overall consumption (Table 2) (Boukli Hacene, 2020).…”

Evaluation approach of terminal energy consumption of public buildings based on a standardized model

“…In order to evaluate the energy consumption level based on a unified standard, eliminating the interference of influencing factors, the standardization and revision of the measurement value of the terminal energy consumption is necessary. [8][9][10][11][12] Benchmarking and evaluating public building energy performance is extensively recognized as a reasonable method for parallel comparison of the building energy consumption level, which can profoundly indicate the orientation of energy efficiency improvement, exploring energy-saving potential. To date, research and analyses of public building terminal energy consumption standardization have attracted considerable attention, and numerous studies have developed a series of reasonable energy benchmarks using various methods.…”
