Description

Technical Field

[0001] The present invention relates to the field of building information technology, and in particular to a modular CAD plug-in calculation method for slope roof greening and photovoltaic integration. Background Art

[0002] As a core form of clean energy, photovoltaic power generation is gradually expanding its application from centralized power plants to distributed, multi-scenarios. Its integration with urban greening and building ecology has become a key trend. Despite the recent introduction of policies and regulations requiring rooftop greening and photovoltaic installations, with specific area requirements, actual designs and proposal changes still face widespread challenges, such as long design cycles, ambiguous bills of materials, errors in manual calculations of investment and returns, and cost and schedule overruns.

[0003] The existing slope roof greening + photovoltaic scheme design has the following main technical problems:

[0004] 1. The design units for rooftop greening and photovoltaics are not unified and are designed independently, which affects the design cycle.

[0005] 2. Information is isolated and updating efficiency is low, making it difficult to quickly iterate design solutions to meet the collaborative needs of complex projects.

[0006] 3. Data fragmentation during the design phase leads to high communication costs and frequent errors.

[0007] 4. During the initial design phase, the architectural model was not intuitively displayed to assist with design decision-making and design communication, lowering the barrier to understanding. The model was not automatically updated through parameter adjustments, allowing material usage and cost data to be directly extracted from the model to reduce manual calculation errors.

[0008] 5. There is no analysis of the benefit weights of greening and photovoltaics, which cannot meet the needs of exploring the feasibility and diversity of solutions.

[0009] Therefore, it is necessary to provide a modular CAD plug-in calculation method for slope roof greening and photovoltaic integration to solve the above technical problems. Summary of the Invention
