A decision making approach for the selection of interior finishing materials in terms of iaq, environmental impact and LCC: Hotel room cases

Luxury hotels are designed to give occupants a high level of comfort. However, designers ignore the issues of sustainability in the interior materials selection process, such as the carbon footprint or the solvent emissions that affect an occupant's health and quality of room. Thus, materials selection is an essential interface to improve the quality and service life, particularly in building's interior atmosphere. The present thesis aims to qualitatively choose the optimal interior finishing materials in terms of IAQ, environmental impact and LCC criteria for hotel buildings. Luxury hotel buildings in Istanbul are used as case studies to evaluate and analyze the interior finishing materials in hotel rooms. Mixed method approach was proposed through determined multi-criteria decision making (MCDM) to select interior finishing materials. The research targets to provide insight into the selection process for luxury hotel designers to evaluate the appropriate attributes and obtain the most optimal finishing interior materials for walls, ceilings, and floors. In this context, it can be foreseen that assessment of the luxury materials in terms of the sustainability aspects that may allow the designers to choose grade premium materials that are also environmentally friendly.
