T/WEA 021-2026 Guideline for implementation of spatial adaptability design and construction in renovation of old building decoration

Scope

This document stipulates the general principles for the design and implementation of spatial adaptability for the decoration and renovation of old buildings, including the investigation of the current situation and collection of information, the requirements for spatial adaptability design, the implementation and process control of construction, quality acceptance and delivery, operation and maintenance, etc. This document applies to the spatial adaptability design, construction, and acceptance activities of existing old building decoration and renovation projects, and can be used as a technical basis for project planning, scheme design, construction organization, and quality control. In China, the scale of existing buildings continues to expand, and old buildings generally face various degrees of degradation and incompatibility issues in terms of structural safety, mechanical and electrical systems, enclosure performance, functional layout, and comfort of use. Decoration and renovation, as an important path for the renewal and transformation of old buildings, often carries multiple goals such as function improvement, quality improvement, spatial reorganization, and optimization of user experience. Compared with new construction projects, old building decoration and renovation is significantly affected by existing structural conditions, original spatial dimensions, the current status of hidden works, comprehensive constraints of pipelines, construction organization conditions, and continuous use requirements, with higher uncertainties in the renovation process, more complex interfaces, and more concentrated quality and safety risks. It is urgent to develop a systematic design and construction implementation method focused on "spatial adaptability" to improve the feasibility of renovation schemes and the stability of renovation effects. The "spatial adaptability" of old buildings not only reflects visual updates at the decoration level, but also emphasizes the
