Scope

This document specifies the evaluation principles and framework, evaluation index system and scoring method, data and calculation requirements, and evaluation implementation and results presentation requirements for the evaluation of low-carbon-oriented residential building design. This document is applicable to the evaluation and optimization of the low-carbon performance of new, renovated, and expanded residential buildings during the schematic design, preliminary design, and construction drawing design stages. Against the backdrop of the continued strengthening of the "carbon neutrality" goal and the green and low-carbon transformation requirements in the construction sector, residential buildings, as an important component of urban building stock and new construction, play a significant role in guiding the planning and design phase of their lifecycle carbon emissions levels. Design elements such as the location and transportation conditions of residential buildings, overall layout and form, thermal performance of envelopes, natural ventilation and lighting, mechanical and electrical system configurations, renewable energy utilization, and material selection and construction practices all have a long-term impact on operational energy consumption, construction emissions, and renovation costs. Establishing a low-carbon-oriented residential building design evaluation method is of great practical significance for guiding design-phase decision-making and optimization with carbon emission reduction as the core goal, and for enhancing the quantifiable, comparable, and verifiable level of residential building low-carbon performance. At present, there are numerous evaluation systems related to green design, energy-saving design, and healthy and comfortable design of residential buildings. However, there are still deficiencies in an evaluation framework that "takes carbon emissions as the main line, covers key stages of construction and operation, and balances feasib
