Energy Design and Multicriteria Decision Analysis in a New Residential Building - Study on the Application of Thermal Insulation and Systems
In this study, an attempt was made to design and study a new two-storey house with energy planning criteria. At the theoretical level, the principles and systems used for building energy planning and the importance of multicriteria analysis in decision-making on this issue were analyzed.
The main criterion for the energy efficiency of the construction outside the bioclimatic design was the thermal insulation of the building where multi-criteria analysis was applied with the Visual Promethee application to select the most suitable thermal insulation material. Equal weights of criteria were analyzed, but also different weights calculated through personal interviews with civil engineers were applied. The results of the two analyses were compared. In the case of analysis with different criteria weights, the expanded polystyrene is followed by stone wool, while for the analysis with similar criteria weights expanded cork ICB is the best alternative.
Also, based on the case with similar weights, the two predominant thermal insulation materials (expanded polystyrene and rock wool) were introduced into the building's components and analyses were carried out showing the needs for cooling and heating of the new home in the four climate environments using Revit. Comparison and annotation of the analyses for the heating and cooling needs according to the peak loads for the two thermal insulation materials in the climate zones also took place.
In terms of peak load for cooling, rockwool in climatic zones B and D exhibits little difference in efficacy in comparison to expanded polystyrene. In the other two climate zones expanded polystyrene predominates. Polystyrene is particularly effective when applied to climatic zone A. On the other hand, for peak loads, rockwool in climatic zone B and D. performs better in climatic zone B than in climatic zone B compared to expanded polystyrene. while in zone D the largest difference is found in the two materials. In the other two zones, expanded polystyrene is superior to rock wool, with a significant difference being present in climate zone A. On the ground floor, climate zones A and C are more efficient, while for the other two, rock wool is the most efficient. On floor for climatic zones C and D the most effective is cotton wool, for climatic zone A expanded polystyrene while for B the insulating materials exhibit similar peak loads for cooling. Finally, the building is presented with proposed interventions such as the addition of passive and energy solar systems, addition of vegetation and devices that enhance natural cooling / lighting.
