Developments of a bim Add-on Tool for Deep Renovation of Buildings

Abstract

This paper presents the current state of development of a generation and performance evaluation tool to assist building practitioners in the early stages of deep renovation of buildings. This includes the tool workflow and its modules, such as the generative design method, the building performance evaluation mechanism, and the optimization procedure that improves the building geometry and construction system, and sizes the energy systems (HVAC and renewable energy production). The tool is currently able to use a wide variety of EnergyPlus objects, allowing for various template and detailed HVAC, DHW, and thermal and electrical energy production systems and components, as well as numerous internal gains types, construction elements and energy saving controls, to be accounted for and simulated in the generated buildings. Some applications examples are presented to demonstrate the tool capabilities. Lastly, some conclusions are made.
