Comparative analysis of an existing public building made from natural building materials and reference buildings designed from common building materials

Abstract

The paper examines a public building constructed of partially natural materials and two imagined buildings with the same geometry, using LCC and LCA methods, with self-developed software. The imagined buildings were designed using the building materials and building mechanical systems commonly used in Hungary which fulfil the relevant energetic requirements in 2010 and in 2019. As a sensitivity analysis the LCA performance of buildings was examined with residential building function. The paper introduces the environmental benefits that can be obtained with natural materials and with other tools in case of the examined building. Based on the results, design strategies can be phrase for environmentally conscious design of buildings with similar scale and function.
