Detailed Rules for the Evaluation of Green Super-Tall Buildings

Thread Content

May 2012 Preface: These Technical Specifications serve as a supplement to the current **standard, the Green Building Evaluation Standard GB/T 50378-2006. They were developed by summarizing the achievements in the development of green buildings in China over the past few years, taking into account the characteristics of super-high-rise buildings, and drawing on advanced experiences from both domestic and international sources, all while adhering to the requirements for resource conservation and environmental protection. The aim is to provide more standardized and specific guidance for the planning, design, construction, and operational management of super-tall buildings, as well as clearer technical principles for the evaluation and development of green super-tall buildings, in order to minimize their impact on urban energy resources and the microclimate environment and achieve healthy and sustainable development. 1 General Provisions 1.1 These detailed rules are formulated to scientifically guide and standardize the evaluation of green super-high-rise buildings, and to better implement the \"Green Building Evaluation Standard\" GB/T 50378.   1.2 These guidelines are applicable to the evaluation of green super-tall public buildings with a height of over 100 meters; they are primarily intended for newly constructed super-tall buildings, while those that are renovated or expanded can also use them as a reference ； The evaluation of green super-high-rise residential buildings is carried out in accordance with the current **standard, the ‘Green Building Evaluation Standard’ GB/T 50378, and the relevant requirements for residential buildings.   1.3 When evaluating green super-tall buildings, it should be done on the basis of the principle of adapting to local conditions, taking into account factors such as the climate, resources, environment, economy, and culture of the area where the building is located, while ensuring safety and functionality.   1.4 The evaluation of green super-tall buildings shall, in addition to complying with these detailed rules, also conform to ** and other local laws, regulations, standards, and specifications, thereby reflecting the integration of economic, social, and environmental benefits. 2 Terms: None. 3 Basic Provisions 3.1 Basic Requirements 3.1.1 The evaluation is divided into two phases: design and operation/use. The evaluation in the planning and design phase is conducted after the construction drawings are completed, while the evaluation in the operation and use phase is carried out one year after the building has passed the completion inspection and has been in operation.   3.1.2 When evaluating individual buildings, for any indicators related to the outdoor environment, the evaluation results of the environment in which that building is located shall be taken as the standard.   3.1.3 The applicant for evaluation shall conduct a technical and economic analysis of the building’s entire life cycle, select appropriate building technologies, equipment, and materials, and submit the corresponding analysis report.   3.1.4 The applicant for evaluation shall carry out process control during the planning, design, construction, and operation phases in accordance with the relevant requirements of these rules, and submit the corresponding supporting documents.   3.2 Evaluation and Rating Classification 3.2.1 The evaluation index system for green super-tall buildings consists of six categories of indicators: land use and outdoor environment, energy conservation and energy utilization, water conservation and water resource utilization, material conservation and material resource utilization, indoor environmental quality, and operation management. The evaluation criteria for green super-tall buildings are divided into mandatory items, general items, and preferred items.   3.2.2 Green super-tall buildings shall meet the requirements of all control items specified in these detailed rules, and shall be classified into three grades according to the degree of compliance with general items and preferred items; the grade classification is determined as shown in Table 3.2.2. Table 3.2.2 Requirements for the number of criteria for classifying green super-tall buildings (during the operation and use phase) [Explanatory notes] There are a total of 99 control, general, and preferred criteria in these detailed rules, of which 33 are control criteria, 49 are general criteria, and 17 are preferred criteria. Compared with the current **standard, the ‘Green Building Evaluation Standard’ GB/T 50378-2006, which specifies 83 requirements for public buildings (including 26 mandatory requirements, 43 general requirements, and 14 preferred requirements), the number of additional requirements is not large. The new requirements are mainly aimed at addressing the characteristics of super-tall buildings, and they are reasonably allocated among mandatory, general, and preferred requirements based on their level of implementation difficulty. Therefore, when determining the requirements for the number of grading criteria, the requirements for public buildings specified in the \"Green Building Evaluation Standard\" GB/T 50378-2006 were directly referenced, and Table 3.2.2 was established by calculating based on the proportionate requirements set out therein. Several (6) items were evaluated on the basis of the requirements in Table 3.2.2, and the results were generally consistent with the expected star ratings, indicating that the difficulty levels set out in Table 3.2.2 are reasonably appropriate.   3.2.3 During evaluation, if a certain provision requires that it be not applicable to the region or climate conditions where the building is located, such provision can be excluded from consideration; as a result, the total number of items to be evaluated decreases, and the requirements regarding the number of items for grading are adjusted accordingly on a proportional basis. Provisions that are not evaluated during the design phase are handled in the same manner. 4 Land Use and Outdoor Environment 4.1 Control Items 4.2 General Items 4.3 Preferred Items 5 Energy Conservation and Utilization 5.1 Control Items 5.2 General Items 5.3 Preferred Items 6 Water Conservation and Water Resource Utilization 6.1 Control Items 6.2 General Items 6.3 Preferred Items 7 Material Conservation and Material Resource Utilization 7.1 Control Items 7.2 General Items 7.3 Preferred Items 8 Indoor Environmental Quality 8.1 Control Items 8.2 General Items 8.3 Preferred Items 9 Operation and Management 9.1 Control Items 9.2 General Items 9.3 Preferred Items Data sourced from: Zhongzhi Building Resources Appendix: Evaluation Form for the Technical Guidelines on Evaluating Green Super-Tall Buildings
