Sustainable modernization method to increase energy performance of the public buildings using BIM techniques

Abstract

This research represents sustainable building modernization model, which creates knowledge-based decision-making method for old public buildings refurbishment seeking to reach the best energy performance during the design stage. Despite the fast development and spreading standards, challenging research opportunities arise from process automation and BIM adaptation for existing buildings' requirements. To aid decision-making, building simulation is widely used in the late design stages, but its application is still limited in the early stages in which design decisions have a major impact on final building performance. Building design is a multi-collaborator discipline, where architects influence design decisions, engineers, contractors, and building owners. Using digital systems and simulations this modernization method performs already expected building energy consumption in a quickest and economic way. This model is BIM-based where design and refurbishment are based on pre-built indicators, which allows assessing the building energy demand and eco-building parameters.
