Abstract
Sustainable development is a priority for the future of our society. Sustainable development is of particular importance to the Architecture, Engineering, and Construction (AEC) industry, both for new buildings and for the renovation of existing buildings. Great potential for sustainable development lies in the renovation of existing office buildings. This paper introduces a new framework for identifying the best set of renovation strategies for existing office buildings. The framework applies selected green building rating system criteria and cost-effective sustainable renovation solutions based on cost-benefit analysis (CBA), and thus provides a novelty in decision-making support for the sustainable renovation of office buildings at an early-stage. The framework covers all necessary steps and activities including data collection, determination of the required level of renovation, selection of the green building rating system, identification of impact categories and criteria, and final evaluation and decision-making using CBA. The framework can be used in conjunction with different systems and according to different regional characteristics. The applicability of the addressing procedure is shown through a case study of a comprehensive renovation of an office building in the city of Maribor.
Highlights
The sustainable development and implementation of projects based on the principles of sustainable development is becoming the present and certainly the future of our society
The main contribution lies in the developed methodological framework of procedures for sustainable office building renovation, which was designed in four steps
The research is limited to the application of the Leadership in Energy and Environmental Design (LEED), Building Research Establishment Environmental Assessment Method (BREEAM), and Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB) rating systems to the renovation of office buildings
Summary
The sustainable development and implementation of projects based on the principles of sustainable development is becoming the present and certainly the future of our society. In the literature for the renovation of office buildings, several methods can be found as decision-making support tools for sustainability assessment such as quantitative multi-criteria or multi-attribute models [28,29]; some studies [27,35] have focused on the optimization of energy demand for building operation with environmental characteristics and cost efficiency. Juan et al [27] developed a hybrid decision support system that included processes to assess the existing sustainability level and recommend an optimal set of renovation measures, taking into account the trade-offs between renovation costs, improved building quality, and environmental impact. The paper contains the common characteristics for the most widely used green building rating systems BREEAM, LEED, DGNB [10,11,12] within the assessment system, impact categories, and assessment criteria used for the renovation of office buildings. At the end of the paper, conclusions and recommendations for future work are given
