ABSTRACT
Building retrofitted to be resilient in the face of future climates may present risks for the health and comfort of the occupants, due to the indoor environmental quality changes involved under current building practices. This chapter is a literature review of recent peer-reviewed papers from a variety of fields identifying such potential hazards. Three topics are investigated: building envelope, HVAC systems and occupants. In terms of the building envelope, resilient buildings currently lead to more airtightness and thermal insulation, which can create humidity problems, accumulation of air pollutants or overheating. HVAC systems, however efficient, can jeopardize the indoor environmental quality, through ducts, filters, noise and maintenance. Respiratory system, eyes and skin conditions can arise with certain retrofitting measures. Moreover, such measures do not necessarily lead to energy savings, partly due to the occupants and their behaviours and partly due to the technologies and their feedback. Human factors should be combined into the development of retrofitting technologies. Thus, interdisciplinarity is needed to develop resilient buildings that will be energy-efficient and also healthy and comfortable for their occupants and the technologies need to be researched as interdependent components to be synthesized in their performance to result in a single enhanced goal.
