“…The role of the users within the tool is an essential element, as one of its main objectives is to overcome the existing barrier of the fragmentation existing within current retrofitting processes. Based on the IPD approach [24], OptEEmAL fosters the interaction and more efficient collaboration among stakeholders, which are represented in the tool as three main roles: project owner, project primer designer and project main constructor, enabling the registration of several users for the roles of prime designer and primer constructor. These three roles are entitled to cover specific steps of the design process and to provide inputs to them, such as the establishment of boundary conditions, All these four processes together allow for delivering more informed decisions and reducing time and costs of the design process, having also an impact on the subsequent stages of the process through elements as the use of BIM.…”

The evident need for improving the existing building stock still suffers from important barriers, such as the fragmentation of the value chain, the lack of information regarding some solutions, and the lack of confidence with respect to energy savings, which prevent unlocking investments, and the difficult communication among stakeholders. Therefore, new processes based on exploiting the potential of existing and new tools are required. In this framework, the OptEEmAL project has developed a tool that integrates stakeholders, data and tools in order to ease the process of designing energy efficient retrofitting projects at building and district scale. This tool works around an optimisation framework in order to evaluate, compare and optimise candidate retrofitting scenarios against a set of indicators showing the performance of the district. This evaluation and optimisation method is based on aggregating indicators through transforming the priorities of stakeholders into a mathematical weighting scheme, which makes it possible to provide scenarios within their expectations. Therefore, the generation of these scenarios is driven by their design parameters, being thus flexible and adapted to their needs. This paper shows the implementation of this tool and specifically 3 different prioritisation schemes, analysing how they impact into the decision making process and selection of the retrofitting strategy.Buildings account for approximately 40% of energy consumption and 36% of GHG emissions in the context of the EU [1]. When analysing the stock of existing buildings, around 30% of the building stock is more than 50 years old [2] and almost 75% is energy inefficient [3,4]. The implications of this energy inefficiency not only result in an energy and environmental cost, but also provoke other impacts, such as health problems due to the low levels of comfort within these buildings [5]. It is then imperative to focus on upgrading an ageing building stock, whose current renovation rates are low, at~1.2%. To achieve these targets, this rate should increase to 3% [6].On the other hand, the retrofitting market is quite fragmented, with multiple stakeholders with different and often conflicting interests. This is mirrored in the communication and information exchanges between them. This strong barrier is added to others, such as the lack of knowledge of some technologies among construction professionals, the varying ambition of performance requirements present within regulations, lack of awareness, and uncertainty as to the expected savings, which make

“…A number of empirical studies have been conducted to identify the critical success factors for GB [16,[40][41][42][43]. Based on previous research regarding GB in Thailand, critical success factors for GB can be classified under the following categories: the competence of the project participants, integration of project team, technical and management innovation, external environment, and project characteristics [41].…”

Green buildings (GB) have been globally adopted for sustainable development by enhancing the resource efficiency, reducing the operation cost, and improving the building environment for users. However, little research has systematically explored the key issues of GB in developing countries. This study has revealed the green technical capabilities and barriers to GB in Thailand from the perspectives of consultants, architects, and engineers, using a questionnaire survey and a case study. The results show experience in meeting the combined requirements of the Leadership in Energy and Environmental Design (LEED) and the green building rating system that Thailand developed in 2010, Thailand’s Rating of Energy and Environmental Sustainability (TREES), and “skilled in energy systems” to be the top two most important green technical capabilities. Barriers to GB mainly arise from financial pressure, technical limitations, and inadequate promotion. “Lack of motivations from owners” and “high initial cost” are ranked as the top two barriers to green building. The results collectively reveal that market demand and technological advancement are fundamental drivers for the GB industry, and the government, economic conditions, education, and corporate social responsibility are the other stimuli for the industry. The findings can help project participants adopt appropriate strategies to boost GB in emerging markets in developing countries. Future policies should focus on increasing market demand, encouraging green technology innovation, and reducing the cost of development and construction of GB.

Abstract:This research aims to develop indicators for assessing green interior design of new residential buildings in China, grounded in the socio-technical systems approach. The research was carried out through a critical literature review and two focus group studies. The results show that the boundaries of green interior design were identified with respect to three dimensions, namely performance, methodology and stakeholders. The socio-technical systems approach argues for the recognition of the interdependence between the systems elements and the feature of embeddedness. The interdependence of the systems elements exists within each of these three dimensions and across them. It is also found that the socio-technical systems of green interior design are embedded in the social, regulatory and geographic context. Taking interior design of residential buildings as the empirical setting, this study contributes to the literature of green building assessment by presenting a socio-technical systems approach.
