Comparative Analysis of Energy Performance for Residential Wall Systems with Conventional and Innovative Insulation Materials: A Case Study

This study was focused on the simulation of energy 
performance for residential buildings incorporating different types of 
insulation materials. The energy consumption of residential buildings in the U.S. 
plays a significant role in the total annual energy consumption, and using 
insulation materials of higher performances is one of the most effective ways 
to reduce the building energy consumption. In this study, the building energy simulation was 
performed in BEopt for a typical 
residential house in the U.S. with several different types of insulation 
materials. The results show that adding insulation materials can significantly 
improve the building energy performance. 
The polyisocyanurate performed the best among the conventional insulation 
materials and had an annualized source energy saving of 37% in Pittsburgh. 
Vacuum-Insulated Panels had the best performance among all types of materials 
discussed in this study and showed annualized source 
energy of 41% in Pittsburgh. Phase Change Material was found to be the most 
effective way to particularly reduce the cooling 
energy use.
