Improving the energy performance of historic buildings has the potential to reduce carbon emissions while protecting built heritage through its continued use. However, implementing energy retrofits in these buildings faces social, economic, and technical barriers. The purpose of this conceptual paper is to present the approach of IEA-SHC Task 59 to address some of these barriers.

Task 59 aims to achieve the lowest possible energy demand for historic buildings. This paper proposes a definition for this concept and identifies three key socio-technical barriers to achieving this goal: the decision-makers’ lack of engagement in the renovation of historic buildings, a lack of support during the design process and limited access to proven retrofit solutions. Two methods – dissemination of best-practice and guidelines – are discussed in this paper as critical approaches for addressing the first two barriers.

An assessment of existing databases indicates a lack of best-practice examples focused specifically on historic buildings and the need for tailored information describing these case studies. Similarly, an initial evaluation of guidelines highlighted the need for process-oriented guidance and its evaluation in practice.

This paper provides a novel definition of lowest possible energy demand for historic buildings that is broadly applicable in both practice and research. Both best-practices and guidelines are intended to be widely disseminated throughout the field.

The purpose of this study was to explore the team process-sequences executed within and across performance episodes and their relation to team performance. In doing so, this effort responds to the call for examining the temporal and dynamic aspects of teams.

Data (i.e. observations and audio recordings) was collected from the stand-up meetings of three high-performing Scrum teams across six points in time during two consecutive performance episodes (i.e. beginning, midpoint, end). After content coding the data, lag sequential analyses was used to examine patterns of executed team processes to determine whether particular process-sequences occurred significantly different from others.

Teams shifted between transition and action phase processes during performance episodes. During and across performance episodes, process-sequences primarily consisted of transition processes. When teams executed process-sequences consisting solely of action phase processes, their focus was on monitoring processes.

This study hopes that the findings here will serve to spur researchers to more fully investigate the relationship between process-sequences and team performance across various team types. However, limitations (e.g. small sample size, unknown point of teams’ life cycle and focus on explicit team processes) should be taken into account when building on the present findings.

This study contributes to a better understanding of the temporal and dynamic nature of team processes by analyzing how the team process and process-sequences occur across time. In addition, this study moves beyond most studies that assess team processes as static retrospective perceptions and consider their natural ordering.

This study aims to advance understanding about quality management (QM) practices by clarifying how competitive strategy conditions the impacts of exploitative and explorative QM practices on performance.

The authors apply partial least squares structural equation modeling to data from a sample of German pharmaceutical firms.

The results show that the impact of exploitative and explorative QM practices on firm performance is contingent on the competitive strategy pursued. Explorative QM practices are significantly more relevant for firms following a differentiation strategy, whereas exploitative QM practices are significantly more relevant for cost leaders. Furthermore, for strategically ambidextrous firms that follow simultaneously a cost and a differentiation focus, the interplay of the two QM practices matters.

This paper contributes to understanding which kind of management practices, exploitative and/or explorative, have greater performance impacts under certain competitive strategy conditions.
