Choosing the right building materials for construction is crucial for achieving energy efficiency and long-term sustainability. At McD BERL, we prioritize early-stage analysis to evaluate materials comprehensively, assessing thermal performance, heat capacity, thermal mass, orientation, and suitability. We analyze admittance and time lag properties to select materials that provide the best thermal stability and comfort. By ranking materials based on energy efficiency, thermal performance, and cost-effectiveness, we ensure optimal recommendations that balance performance and budget.
