Abstract
In line with the activities within IEA EBC Annex 69 Subtasks A, B, and C, the present report includes four main sections, addressing the above listed identified challenges and barriers to the adoption of the adaptive thermal comfort in practice by explaining the adaptive thermal comfort principles, by illustrating the benefits from applying the adaptive principles in buildings, through guidance on how to implement the adaptive principles in the design and operation of buildings, especially providing guidance on how to design for adaptive opportunities. The Appendices contain additional information on standards, checklists for stakeholders in the design and operation of buildings as well as documentation and lessons learnt from the buildings investigated within this Annex 69 Subtask C.
This report is formulated with the help of frameworks (Hellwig et al. 2019, Hellwig et al. 2020) developed to facilitate the adoption of adaptive principles in the design and operation of buildings. We aim to provide the knowledge on a general level of understanding, so that it is possible to apply the knowledge in different types of building usage, different climate zones and occupant groups. However, the majority of examples used in this report stems from office buildings, which is mainly rooted in the fact that the majority of research studies focussed on this type of building. Nevertheless, we have supplemented this report with examples from other building types.
The target group of the guidelines in this report are building planners (architects, engineers, sustainability certification consultants/councils) and building operators (facility managers, operators, owners, and tenants). Furthermore, the guidelines in this report are intended as critical sources and guidance to educate future building professionals and stakeholders.
The report includes four main sections, as outlined below.
Section 2 summarises the three adaptive comfort principles, i.e. physiological, behavioural and psychological adaptation. The section follows with a discussion on the effectiveness of the adaptive principles and on the order of activation of adaptive responses. It ends with a brief account on the development of adaptive models.
Section 3 describes the benefits from applying the adaptive principles in buildings, including energy savings, resilience to climate change, improved usability and thermal satisfaction, as well as improved health and well-being.
Section 4 presents the developed framework for adopting the adaptive comfort principles in design and operation of buildings. The main elements of the framework are described, i.e. the building context, adaptive responses and actions, the building planning and design, –the adaptive opportunities design, and the operational planning and operation. Each of these subsections includes guidelines to facilitate the integration of adaptive principles. Section 4 ends with considerations and recommendations for adopting adaptive comfort in conditioned buildings, including advice for facilitating free-running mode in building operation as often as possible and ways to integrate the use of the adaptive principles in permanently or long-season conditioned spaces.
Appendices
Appendix 1 summarises information on adaptive models used in international and national standards, as well as examples of models developed by research in various locations and climates.
Appendix 2 provides checklists of parameters that can help stakeholders implement measures to ensure the availability of adaptive opportunities in buildings.
Appendix 3 is a collation of case studies with practical learnings from adaptive buildings investigated in Annex 69 Subtask C.
Appendix 4 lists publications, presentations and workshops related to Activity B2 of IEA EBC Annex 69.
