Economically and Islamically Sustainable Interior Design in Residential Projects: Evidence from Lahore, Pakistan

Abstract

The present study examines the effect of economic and Islamic sustainability principles upon sustainable interior design practices in residential projects in Lahore, Pakistan. As the cost of building and the demand for culturally appropriate living condition rose, the research focuses on the relationship between cost efficiency and the Islamic ethical values and their effect on the behavioral intention on sustainable interior solutions. A quantitative research design was used and primary data collection involved 270 participants such as architects, interior designers and homeowners. The three constructs namely economic sustainability, Islamic sustainability principles, and behavioral intention were measured through a structured questionnaire. The data collected were analyzed using the Partial Least Squares Structural Equation Modeling (Smart PLS). The measurement model showed good results of reliability and validity such as composite reliability, average variance extract (AVE), and discriminant validity. The results of the structural model provide evidence to support the positive relationship between each of the economic sustainability and Islamic sustainability principles with behavioral intention, with a positive and statistically significant relationship. The affordability, energy efficiency, and best use of resources will be key considerations in decision making, with economic sustainability being the more powerful predictor. Islamic principles of sustainability, such as moderation, avoiding excessive consumption and moral responsibility, also play a significant role in determining the preferences of users and to reinforce sustainable behavior. The study suggests that the adoption of Islamic interior design can be encouraged by the holistic approach of applying economic efficiency and Islamic values. The results of this study highlight practical lessons for designer, policy makers and developers to promote affordable, culturally responsive and environmentally sustainable indoor environments in developing countries.
