Green and Sustainable Certifications for Existing Buildings, the Example of the Upgrading to Standards and Heritage Restoration of Montreal City Hall

Abstract

The energy efficiency of new construction is increasingly valued and put at the forefront of building design. However, the built environment of cities is generally highly developed and the reconstruction of buildings is obviously not a solution. From a sustainable development and energy efficiency perspective, it is essential to consider the conversion of existing buildings of all types into efficient buildings. The objective of this project is therefore to determine the green and sustainable certification options available to date for existing buildings and to consider the application of WELL certification for health and well-being to a real project, namely the upgrading to standards and heritage restoration project for Montreal city hall.
