An Integrated Evaluation Framework for Sustainable Residential Construction

Sustainable development issues and environmental concerns continue to gain headlines as demand for housing escalates within the residential construction industry. Current building practices adhere to traditional methods of construction that pose weaknesses such as high labour costs, negative environmental impact during and after construction, and minimal technological advancement. The results of this research will address the limited attention given in the present literature to green construction products, prescriptive practice criteria sustainability rating and benchmarking sustainability scores. There are numerous factors and constraints that contribute to construction material waste, each with varying impact on the type and quantity of waste. After identifying these factors, an analysis will be conducted to evaluate their magnitude and affect on sustainability. Factors include weather, material layout on site, scheduling, transportation, trade skill or experience, socio-economic conditions and regulations. There will be development of a knowledge-based expert system (waste database registry) and tracking of these material waste variables along the construction timeline in terms of quantity, source, greenhouse gases, and costs. At the downstream end of construction, programs and systems will be evaluated based on reuse and recycle opportunities, instead of being hauled and disposed of in landfills. Legislation regulating material and landfill restriction policies related to construction waste will be examined to illustrate its potential economic and environmental impact. The integrated evaluation framework include: determination of appropriate green building programs; evaluation of various building rating software assessment tools; analysis of current construction methods; analysis of material and product selection; development of a multi-criteria optimization model for building rating certification; a proposed integrated evaluation framework for sustainable construction; and development of a sustainability knowledge management system The stakeholders benefiting from this research will include the general public, owners, designers, builders, and government agencies.

Dr. Mohamed Al-Hussein

Associate Professor, Construction Engineering and Management, University of Alberta
Edmonton, Alberta, Australia

Dr. Al-Hussein is interested in project management, including resource, facility, equipment, procurement management, as well as project cost control and claims analysis. He is also interested in computer modeling with regards to business process modeling and data modeling in construction. Currently he is at work on a project which utilizes 3D-Solids CAD modeling, object oriented methodology, and information management systems with regards to construction automation. The CAD model, prepared by the architect, integrates with other external information systems, such as databases, using object-oriented methodology. This research is intended to expand in the knowledge that exists in the field of construction automation
