ISO/DIS 11855-8 Building environment design

As of my last update in January 2022, ISO 5020:2022 “Waste reduction and treatment on fishing vessels” is not an existing ISO standard. If this standard were to be developed in the future, it would likely provide guidelines and requirements for reducing and treating waste generated on fishing vessels to promote environmental sustainability within the fishing industry.

As ISO standards are typically developed through a rigorous process involving experts from relevant industries and sectors, the content of ISO 5020:2022 would be based on consensus among stakeholders and informed by best practices in waste management and environmental stewardship specific to fishing vessels.

If you have a specific inquiry about ISO 5020:2022 or would like to discuss hypothetical content, please provide more details or let me know how I can assist you further.

What is required ISO/DIS 11855-8 Building environment design


ISO/DIS 11855-8, currently a Draft International Standard (DIS), is part of the ISO 11855 series titled “Building environment design – Design, dimensioning, installation and control of embedded radiant heating and cooling systems.” This series of standards provides guidelines and requirements for the design, dimensioning, installation, and control of embedded radiant heating and cooling systems in buildings.

ISO/DIS 11855-8 specifically focuses on aspects related to the building environment design. While the specific requirements outlined in ISO/DIS 11855-8 may vary until the final standard is published, typically, standards in this series address topics such as:
