ISO 16745-1:2017 Sustainability in buildings and civil engineering works
Released by the International Organization for Standardisation (ISO) 16745 Part 1 & 2 will provide a set of methods for the calculation, reporting, communication and verification of a collection of carbon metrics for greenhouse gas (GHG) emissions arising from the measured energy use during the activity of an existing building.
This means that determining and reporting a carbon metric of an existing building, or associated with the operation of the building, will become easier and will help reduce GHG emissions.
Jacques Lair, chair of the ISO subcommittee that developed the standard, said: “At a time when global warming is becoming more and more evident, with its devastating effects on the entire planet, having a tool to measure the carbon footprint left by buildings is of utmost importance. ISO 16745 will bring a response to the expectations of all.”
Buildings are responsible for more than 40 % of global energy used, and as much as one-third of global greenhouse gas emissions, both in developed and developing countries. But the building sector also has the largest potential for significantly reducing GHG’s compared to other major emitters.
In this context, measuring and reporting GHG emissions from existing buildings is critical to enable significant and cost-effective GHG mitigation. Until now, there has been no globally agreed method to measure, report and verify potential reductions of GHG emissions from existing buildings in a consistent and comparable way.
Useful for a wide spectrum of users
ISO 16745 aims to be practical not only for the building profession, but for many stakeholders who are expected to use the carbon metric of a building as reference for decision making in their business activities, governmental policies and as a baseline for benchmarking. The simplicity of its approach means it is applicable at all scales, from cities and building portfolios to individual buildings.
The standard could be used as a universal tool for measuring and reporting GHG emissions, providing the foundation for accurate performance baselines of buildings to be drawn, national targets to be set and carbon trading to occur on a level playing field.
