DETAILED DESCRIPTION

[0012] Embodiments of the present disclosure are described in detail below with reference to examples thereof shown in the attached drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0013] Urban development has shifted from large-scale incremental construction to stock upgrading and incremental structural adjustment, and existing building reconstruction has become the main content of urban construction and development, and is an important support for the implementation of urban renewal action. Buildings are one of the important material conditions for human society to survive, and have an important supporting and promoting role for social development. The existing building reconstruction has a large workload and wide range, and the situation is complex. Various different situations will be encountered in the reconstruction process, which will affect the building reconstruction method and direction. Therefore, in order to avoid detours and wrong roads in the building reconstruction process, building value evaluation is generally needed before building reconstruction to determine the building reconstruction method and direction.

[0014] In view of the above, the present disclosure provides a value evaluation method for existing building reconstruction. Figure 1 is a value evaluation method flow chart of existing building reconstruction according to an exemplary embodiment. As shown in Figure 1 The value evaluation method for existing building reconstruction comprises: Step 10, obtaining building information of a target building; Step 11, performing value evaluation on the value of the building based on the building information of the target building and a building value evaluation model to obtain a building value evaluation result; wherein the building value evaluation model comprises at least one of a cultural value evaluation standard, a safety value evaluation standard, a use value evaluation standard, a science and technology value evaluation standard, an environmental value evaluation standard, and an economic value evaluation standard, and the building value evaluation model is formulated based on the characteristics of different projects; wherein each evaluation standard corresponds to a plurality of evaluation grades from comprehensive to gradual progression, and each evaluation grade comprises a plurality of evaluation indexes.

[0015] Exemplarily, the building information involved in different projects is also different, and different evaluation indexes can be formulated according to the characteristics of different projects. For example, the cultural value evaluation content used between two projects is different, and the safety value evaluation content is the same.

[0016] For example, ① independent single evaluation of a value. For example, the owner only wants to evaluate the safety value of the existing building, or a building has been in use for less than 5 years, and the owner plans to upgrade the use efficiency without changing the use function, and the use value evaluation can also be selected. ② Select a few values for evaluation. For example, the owner plans to upgrade an office building in a historical and cultural block that has been in use for about 2 years. In this case, if there is no other special demand, it is usually recommended to prioritize the evaluation of cultural value and use value. ③ Based on the reconstruction potential evaluation in the index disassembly principle, the present application takes into account the cases where the function is changed after reconstruction and the positioning is uncertain.

[0017] It should be noted that the building value evaluation model is prepared in advance based on the needs of the project, and the building value evaluation model automatically evaluates the value based on the building information of the target building.

[0018] In the present exemplary embodiment, by establishing a building value evaluation model, the building is comprehensively evaluated from six aspects based on the building information of the target building through the building value evaluation model, so as to obtain a more accurate building value evaluation result, and to provide an accurate basis for subsequent judgment of the reconstruction direction of building reconstruction.

[0019] Figure 2 is an evaluation index diagram according to an exemplary embodiment.

[0020] In the present exemplary embodiment, each evaluation standard corresponds to a plurality of evaluation grades from comprehensive to gradual progression, including: The cultural value evaluation standard, the safety value evaluation standard, the use value evaluation standard, the scientific and technological value evaluation standard, the environmental value evaluation standard, and the economic value evaluation standard each correspond to a first grade evaluation index, a second grade evaluation index, a third grade evaluation index, and a fourth grade evaluation index. The first grade evaluation index, the second grade evaluation index, the third grade evaluation index, and the fourth grade evaluation index each correspond to different scoring details.

[0021] For example, as shown in Figure 2 The present application establishes 6 first-level indexes, 21 second-level indexes, and 181 third and fourth-level indexes, wherein there are independent influence indexes in cultural value and safety value, which need to be evaluated first.

[0022] In the present exemplary embodiment, each evaluation criterion corresponds to a respective first, second, third, and fourth level evaluation indicator. The first to fourth level evaluation indicators are from comprehensive to gradually progressive. The first to fourth level evaluation indicators have gradually refined value evaluation indicators, thereby facilitating more comprehensive and refined value evaluation of the target building.

[0023] Figure 3 is another value evaluation method flowchart of a reconstruction of an existing building according to an exemplary embodiment, comprising steps S310-S350.

[0024] Step S310, collect the status quo basic information of the existing building.

[0025] Exemplarily, obtain the basic information and data of the existing building to be evaluated, including but not limited to basic information such as project completion time and building scale, design documents such as design drawings, structural calculation books, and mechanical and electrical equipment parameters, operation and maintenance documents such as housing property management and maintenance records, and existing various detection and evaluation identification reports, communicate with the owner to confirm the specific scope of the project for value evaluation, whether to evaluate a single or several values or to conduct comprehensive evaluation.

[0026] Step S320, judge the independent influence indicator.

[0027] Exemplarily, judge the independent influence indicator, including safety value and cultural value. If the independent influence indicator meets the limited condition, only demolition or repair is allowed, and reconstruction is not allowed. If there is no independent influence indicator, go to step S330 to develop the value evaluation of the reconstruction of the existing building. The office building is not a certified cultural relic protection unit or historical building, and there is no independent influence indicator in terms of cultural value. The office building has no situation that must be demolished, and there is no independent influence indicator in terms of safety value.

[0028] Step S330, evaluate the cultural value, safety value, use value, scientific and technological value, environmental value, and economic value.

[0029] Exemplarily, comprehensively and gradually evaluate the target building from the cultural value, safety value, use value, scientific and technological value, environmental value, and economic value. Before the level evaluation, the evaluation indicators of each building value evaluation model should be selected according to the building information and requirements of the target building, the scores corresponding to each evaluation indicator should be converted in proportion, and a quantitative evaluation should be conducted. The red line range of the example office building is small, and there is almost no space for staying outside the building, so all the indicators related to the space are not evaluated, and the content of the value evaluation score table is confirmed. Secondly, carry out investigation, detection and other evaluation work, and score each indicator. Finally, calculate the value scores and judge the grades of each type of value.

[0030] Exemplarily, there are three kinds of scoring logics: The first kind, full score for meeting, 0 score for not meeting; For example: use value (first level evaluation index) - convenient transportation (second level evaluation index) - good building internal logistics organization, reasonable flow line planning of cargo transport and garbage classification and cleaning transport, convenient and efficient use (third level evaluation index), which is divided into two fourth level evaluation indexes: a reasonable flow line planning of cargo transport, reasonable planning and good use of unloading area, reasonable setting and good operation of logistics equipment, convenient and efficient cargo transport system. 1.5 points.

[0031] b reasonable setting and good operation of garbage disposal and cleaning transport equipment, reasonable organization of garbage classification and cleaning transport flow line, convenient and efficient use. 1.5 points.

[0032] The second kind, according to the corresponding level of scoring basis, score several points according to which level; For example: use value (first level evaluation index) - reasonable space design and use (second level evaluation index) - high building space use efficiency (third level evaluation index), the scoring basis is: a high building space use efficiency, good flexibility, good foundation for transformation, 4 points.

[0033] b poor building space use efficiency, but good flexibility and transformation potential, 2 points.

[0034] c poor building space use efficiency and flexibility, and no transformation potential, 0 points.

[0035] The third kind, cumulative score, full score.

[0036] For example: scientific and technological value (first level evaluation index) - scientific and technological still advanced (second level evaluation index) - scientific and technological still in line with national policy guidance, superior technology performance, advanced and representative (third level evaluation index).

[0037] Determine the evaluation score of each value of the target building through quantitative evaluation, and determine the evaluation level of each value according to the score.

[0038] Specifically, the score grading is set to three levels, high, medium and low, with high ≥ 70 points, 70 points > medium ≥ 40 points, and 40 points > low. Different current value situations will correspond to different target orientations and transformation strategies during the transformation process. If the current value is at a high level, the current value should be fully utilized during the transformation; if the current value is at a medium level, the current value should be fully excavated during the transformation, and appropriate technical strategies should be adopted to improve the current value by comprehensively considering various factors; if the current value is at a low level, the current value should be dialectically treated during the transformation, and the current value should be remodeled by comprehensively considering various factors.

[0039] The cultural value of the project is 40.4 points; the safety value is 15 points; the use value is 53.2 points; the scientific and technological value is 30 points; the environmental value is 33 points; and the economic value is 86 points. Among them, the economic value is at a high level and needs to be developed; the use value and the cultural value are at a medium level and need to be excavated; the safety value, the scientific and technological value, and the environmental value are at a low level and need to be remodeled.

[0040] Step S340, comprehensive evaluation conclusion.

[0041] Exemplarily, the values are sorted by combining the grades of various values, the needs of the owners, etc., and suggestions are provided. In terms of cultural value, the project carries the collective memory of more than 30 years of work and life of the enterprise, and its value mainly lies in the architectural appearance and structural form, etc., which should be paid attention to in the transformation. In terms of use value, the building has been built for a long time, and there are many problems in space, indoor and outdoor environment, accessibility, and old mechanical and electrical facilities, etc., which do not meet the requirements of the current specifications, and must be improved in the transformation. The function of the project is office before and after the transformation, and there is no disruptive spatial demand due to functional change, but because of the new era and new requirements and quality requirements, the use value and spatial transformation potential still need to be seriously excavated. In terms of scientific and technological value and environmental value, the standards of the building at the time of construction and transformation are quite different, so the scores are relatively low, but the space foundation is good, and there is a lot of room for improvement, but it will require corresponding economic requirements. In terms of economic value, it has a high current economic value from the perspectives of location and land value-added, etc. After comprehensive analysis of the transformation cost and future expected benefits, it is economically feasible, but needs to be balanced with other values, so as to achieve a better benefit.

[0042] Step S350, support transformation decision.

[0043] Exemplarily, based on the current situation of the building and the transformation demands of the owners, the value sorting of the project is safety > use > culture = environment = scientific technology = economy; the safety value is the most important, followed by the use value, and then the culture, and the scientific technology, environment and economic value are comprehensively balanced on the basis of considering the previous values to achieve an optimal solution.

[0044] Exemplarily, based on the above-mentioned obtained value evaluation score and qualitative evaluation result, comprehensive consideration is performed to obtain a renovation direction suggestion for the existing building.
