How can you interpret construction drawings for sustainable and green buildings?

2 The principles of sustainable and green buildings

Sustainable and green buildings are designed to minimize the negative impacts on the environment and human health, and to maximize the positive impacts on the social and economic aspects of the project. Sustainable and green buildings follow the principles of energy efficiency, water conservation, waste management, indoor environmental quality, and site selection. These principles are often reflected in the construction drawings by using specific symbols, codes, standards, and conventions that indicate the performance and certification of the building. For example, you may see symbols for renewable energy sources, water-efficient fixtures, recycled or low-emitting materials, natural ventilation, or green roofs.

3 The standards and certifications for sustainable and green buildings

There are various standards and certifications that measure and verify the sustainability and greenness of a building, such as LEED, BREEAM, Green Star, or Passive House. These standards and certifications have different criteria and levels of performance that require different documentation and verification methods. Construction drawings are one of the sources of evidence that demonstrate how the building meets the standards and certifications. To interpret construction drawings for sustainable and green buildings, you need to be familiar with the requirements and guidelines of the relevant standards and certifications, and how they are shown in the drawings. For example, you may see labels, ratings, or logos that indicate the certification level or category of the building.

4 The tools and techniques for interpreting construction drawings

Interpreting construction drawings for sustainable and green buildings requires some tools and techniques to read and understand the drawings more accurately. A scale ruler can measure the dimensions and proportions of the drawing according to the scale indicated in the title block. Additionally, a legend or key can explain the symbols, abbreviations, annotations, and notes used in the drawing. Moreover, a cross-reference system can link different drawings and show how they relate to each other and to the design intent. Lastly, a checklist or template can help you identify and verify the elements, materials, systems, and performance of the building according to the standards and certifications.
