“…However, particular requirements are found between office and residential retrofit methodologies due to different ownership, occupancy, and end-use patterns [10,11]. Recent developments in knowledge systems methodologies for residential energy retrofitting can be mentioned such as: integration of national construction databases [12,13], standalone programs providing real-time evaluation of energy interventions [14], methodologies developed for risk assessment of retrofit decisions for individual buildings [15], and for complete districts [16]. Integrative approaches between energy and economic aspects exist but their implementation is complex [17,18].…”

a b s t r a c tA very large percentage of the European residential building stock is ageing and does not comply with current energy regulations. The need to complete short-term energy upgrading on these buildings in order to improve performance and meet current regulations poses a considerable challenge. Consistent energy methodologies are needed for mass application of suitable technologies in sensitive points such as the façade, saving time by guiding designers on use of preferred climatic design strategies for each situation and with economic feasibility.The paper presents a methodology with integrative approach between energy and economic aspects, using an inference system to overcome uncertain or unknown information found at the start of the project. Components used in the analysis are studied from a programmatic point of view (input, decision process and output). The methodology is suitable for early stages of the design process and its products enable continuation into more advanced ones. The methodology can form the basis for a software program using either its own databases or integrated energy simulation engines.This work is based on research for a European project concerning energy retrofit of residential building facades, but can be extended to other zones or end-uses having similar approaches.

“…In the literature, some authors have given concern towards identifying the process to determine the most suitable ER measures for a particular project (E.g. [24], [25]) whereas others have made an attempt to come up with a systematic approach for identifying, determining and implementing ER projects (E.g. [7], [26]).…”

Poor energy performance of existing buildings worldwide has led to a crucial need to retrofit existing buildings to minimise energy consumption. Among the existing buildings, hotels use as much as 50% of their total expenses on energy and offer significant opportunities for energy efficiency improvement. Yet, comparatively the level of implementation of energy retrofits found to be low, which has attributed to, inter alia, the absence of a clearly defined process for ensuring the delivery of energy retrofit projects and lack of proactive guidance for project teams to ensure that they make the right decisions at the right time to achieve the desired outcomes. Since many energy retrofit projects in existing hotels are carried out with the involvement of an external contractor, or an Energy Service Company (ESCO), this study focuses on investigating the decision-making process in implementing energy retrofits when the project is outsourced to an external party. An in-depth case study is used to obtain insights into the critical decisions to be taken and key activities to be performed throughout the decision-making process. The findings are used to propose a step-by-step decision-making process comprising of three key phases: i.e., pre-retrofit, retrofit implementation and post-retrofit. It is hoped that the decision-making process developed in this study will serve as a roadmap for the effective adoption and implementation of energy retrofits in existing hotel buildings when an external contractor is involved.

The presentation of information to help homeowners make retrofit decisions has been identified as a major problem. While homeowners often depend on energy auditors and trade contractors as retrofit experts, information provided by them based on their knowledge, can be incomplete and even inaccurate. To the expert, knowledge is often implicit, usually committed to automaticity, and difficult to articulate. This research attempts to establish the determinants of expert knowledge in the home energy retrofit industry. Using literature review, Delphi, and nonprobability sampling techniques, 23 participants participated in the study. The findings identified key attributes of home energy retrofit experts. Based on these attributes, an expertise identification system, suitable for the selection of home energy retrofit experts was developed. The study contributes to understanding the role of expert knowledge generally and the home energy retrofit domain specifically and provides an effective metric for determining industry experts.
