If flexibility is the ability of a system to be easily modified and to respond to changes in the environment timely and conveniently, it can be considered as the antidote to obsolescence or the characteristic of the system that guarantees slippage over time. Our paper focuses on the concept of flexibility as a fundamental prerequisite for residential building in order to extend its life cycle design, through strategies and constructive solutions that ensure both the convertibility of the space in response to changing usage and the use of building materials that encourage the reversibility and the long-term easy maintenance of the technological choices that have been implemented. Flexibility is examined both from a conceptual point of view, so as to obtain a clear and logical definition that is distinct from related terms, as well as from a practical point of view, by finding ways to incorporate this requirement into the designing of housing.展开更多

Since, ＂everyone should be able to enter and use any part of the built environment as independently and naturally as possible＂, the old buildings should be revitalized with respect to an inclusive approach. However, research on current design practice showed that there is a lack of systematic evaluation and revitalization methods. Hence, the main objective of the proposed UHEM model is to evaluate existing residential environments and requalify them with respect to an inclusive approach. The study concludes by highlighting the importance of UHEM from two points of view： （i） the importance of a systematic evaluation approach to effectively deal with the challenge of requalifying the residential environments and （ii） the designers＇ key role during the revitalization process.展开更多

Integration and flexibility are tendencies for telecom energy solution development, also the keys to improve energy efficiency. With plentiful design and implementation experience, the author provides a three-dimensional energy matrix model to design a perfect energy system, and some practical measures of integration and flexibility are also shared from mechanical to electrical, from single site to whole network.展开更多
