Multi-Criteria Problems of Energy Consumption in Buildings Considering Technical and Economic Indices

Abstract

This study focuses on economic modelling of the energy consumption in buildings considering controllable appliances scheduling in stand-alone electrical grids. The economic modelling is implemented via coordination of the energy generation of the renewable energies with controllable appliances by using demand shifting strategy (DSS). On the other side, uncertainty and stochastic modelling of the renewable energies are considered in the optimal coordination. Also, optimal coordination is modelled by multi-criteria problems of the technical and economic indices. Solving of the multi-criteria problem is done by fuzzy and augmented epsilon-constraint methods. To investigate the effectiveness of the proposed model, it is applied on a 25-node test system through defining two scenarios. The obtained results show that modelling the optimal coordination to supply the demand of the grid can increase the efficiency of the system.

Case Study of EPS Aggregate Insulation Material Used in Construction Sites

“…There are no questions that thermal insulation materials have a vital role in reducing environmental pollution and in the reduction of greenhouse gas release in the maintenance of the building. Thermal insulation materials minimize heating and cooling costs, reducing fuel consumption for heating or electricity consumption and solving multicriteria problems of energy consumption in buildings [2]. The use of traditional insulation materials in civil engineering, such as rockwool, glass wool, and foamed plastics (EPS, XPS, PIR/PUR) is widely accepted by designers and customers.…”
