Abstract—Sustainability in building design is a practice that consists of design ideas and functions responsible to keep the building or object in working condition with minimum possible consumption of energy, resources and monetary cost. Whereas in contemporary world sustainable built form is consider as a design scenario incorporated with scheme to control and bring down the reduction in maintenance of building. Unlike modern days, conventionally the building maintenance procedure used to be undertaking after the evaluation of the building condition. But in contemporary time building maintenance become the part of good sustainable design proposal. Despite the technological advancement of contemporary time prevention of building from unplanned maintenance is still an unsolved riddle which requires constant research to get it solved. In this hi-tech society buildings still suffers from the various issues of maintenance causes from decisions of their designer. It is a general observation that present day buildings are more vulnerable to maintenance as compare to older counter parts. The objective of this article is to appraise the responsibility of various factors of design contributing to destabilize the sustainability and initiates maintenance in building. In order to develop better understanding of subject this article is aims to explain the issues of maintenance and design in systematic development. Therefore dividing it into two parts i.e. Part-1 Introduction of field and developing understanding for formulated definitions and standards, Part-2 Assessing the design factors that deter sustainability and responsible for causing maintenance and finally reaches at conclusion. Keywords—Design Faults, Sustainability, Building Maintenance and Implications. I. INTRODUCTION OF FIELD AND DEVELOPING UNDERSTANDING FOR FORMULATED DEFINITIONS A. Introduction Responsibility of sustainable design towards building maintenance has remained neglected part in field of research, modern society and especially in underdeveloped nations. Designer usually does not realize that what mistakes or bad decision have been taken during design process and those are Che-Ani A.

Those decisions are mostly emerge in form of certain types of building defects (unplanned maintenance) and unfortunately such unforeseen conditions are the part of daily life for end user of the buildings. The subject matter of this article has gained certain momentum and attracts good number of researchers to address the similar problem in other parts of globe. They have highlighted the vitality of topic through their publications and also developed a reliable link between the Design and Maintenance issues. According to Ramly, A. (2006), design plays a major role in determining the conditions of the building after completion, mainly in aspects of defects and maintenance. Indirectly design influences the performance and physical characteristic of building and its durability to with stand against environmental condition, social interfaces such as graffiti and vandalism. The study further stress that the link between design and maintenance should not only seen from the point of increasing the repair work or cost involve, but it need to consider also the impact of design on structure and material installed as well as the life cycle of each component of building. In near past it was considered that only old buildings are subject to maintenance because of material decay, weathering, etc but in contemporary time, thanks to designers, developers and construction teams as the concept has totally changed. Now even newly built structures are subject to intensive maintenance and sometimes require revised design and reworks. A poor/faulty design is not only concerned with designer of building but also concerned with construction team. Even the gap between these two professions has resulted in public concern and public confidences in both professional are undermined. Study of Foo (1989) highlights the issue of faulty design as, in recent years many defects, premature maintenance and failure are occurring in relative new buildings. Thus this situation has resulted in much public concern and it reached at a point that public confidence in both professionals and construction sectors are undermined. However it would be justified to declare that even new and modern designs of the building are more vulnerable to get infected with plague of unplanned maintenance, if their respective design has not been considered skillfully in terms of maintenance. However Zavadskas, E. (1998) have presents the correlation between design of building and its life cycle. A better building life is only accessible with skillful design consideration at design stage and is important issue to its Sustainable Design Formulation in Achieving Best Practice of Building Maintenance Che-Ani A.I., Chohan A.H., N.A.Goh, M.M.
