ISO 15392:2019 Sustainability in Buildings and Civil Engineering Works is an international standard that provides guidelines for the design, construction, and maintenance of buildings and civil engineering works.

It provides guidance for sustainable design objectives, including reducing energy use, conserving resources, and minimizing environmental impacts.

The standard covers sustainability topics such as energy efficiency, water efficiency, materials use and selection, waste management, indoor air quality, and sustainable design objectives. It also addresses the social and economic aspects of sustainable building design and construction.

The standard focuses on the design, construction, and maintenance of buildings and civil engineering works to ensure they meet current and future sustainability goals. It includes guidelines for the selection of materials and products that are environmentally friendly, energy efficient, and resource efficient, as well as guidelines for the reuse and recycling of materials and products.

One of the most important aspects of the standard is its emphasis on the assessment of a building's overall sustainability performance. This includes the evaluation of a building's energy efficiency, water efficiency, and environmental performance. The assessment process requires the use of a sustainability rating system, such as LEED or BREEAM, to measure a building's performance over time.

The standard also encourages the use of renewable energy sources, such as solar and wind, for the generation of electricity and heating. It also encourages the use of renewable materials and the reuse of existing materials. The standard also addresses the use of green infrastructure, such as green roofs, green walls, and other green spaces, to provide environmental benefits.

ISO 15392:2019 Sustainability in Buildings and Civil Engineering Works is an important standard that provides guidance on how to design, construct, and maintain sustainable buildings and civil engineering works.

It provides guidance on the selection of materials and products with low environmental impacts, energy and resource efficient design, and the reuse and recycling of materials and products. It also encourages the use of renewable energy sources, green infrastructure, and other sustainable design objectives.
