EUI
Quality, Consequences and the Construction Industrial Complex (part 341).
Carbon offsets are a bit like an obese person paying a slim person to stand next to them so the obese person can be "certified slim".?
The intention to reduce carbon is good, the execution using carbon offsetting IMHO, obfuscates reality and evolves into a luxury good or tax depending on where you are in life's economic sandwich.?
Embodied and operational carbon are important considerations, particularly during building design. However, if we are to really do something about the built environments impact on resource scarcity and pollution we need to utilize an easy to measure and understand metric. For me the best metric is Energy Use Intensity (EUI).
Absolute KWh/M2/year is IMHO a?superior metric because it is energy supply agnostic. It measures energy at the meter and is influenced by:
These are all areas where there is vast room for improvement using technology, modular construction, machine learning and real time monitoring of performance.?
To add context, EUI benchmarks in the UK are currently:

Why is EUI not widely used? I do not know, maybe it is too much of a reality check? The truth can hurt.

In my fantasy job as mayor of all cities, I would pass a law requiring all buildings to report publicly, gross area and quarterly meter readings. The data would be posted online via a "heatmap" and then we will know how well buildings are really performing.?
To encourage competition between building owners I would provide incentives via property tax hikes for poor performance and tax reductions for exceeding target, This would speed up the rate of change and create jobs.
I am quite sure I would be a one term mayor! However, if we believe the time for action is now, then we need a metric we can all use and monitor.?

2 年What we need to advocate for is sharing of EUI information. So much is collected but it's kept secret. https://buildingbenchmarkbc.ca/ is one example of trying to buck this trend. So here's some info from my recent home energy audit. My EUI is 124 GJ/year. It's bad and it will take time to improve it.

2 年Bravo Adam. EUI is a metric all countries should adopt as a true measure of building performance.

2 年Are those UK EUI benchmarks averages across building types or just commercial real estate? What would they look like for acute healthcare specifically?

2 年Look forward to your EUI heatmaps Adam Muggleton, great idea.
