As part of our annual reporting, starting with our 2020 report, we calculate the ‘energy footprint’ of our buildings to see how energy efficient we are being, and identify ways we can make improvements. We do this using a tool from the Church of England which calculates emissions from the different types of energy we use, takes into account any offsetting we do, and then compares it to our building size and usage.
Nowadays A–G ratings are applied to many buildings and products. The system used here to calculate efficiency is roughly equivalent to national Display Energy Certificates for public buildings.
Bands are awarded as good as A++, or B, C or D, all the way down to G which is the poorest rating.
Churches might get very different ratings for CO2e and for person-hours. Many churches use little energy compared to their size because they may not be hosting many activities. Others are squeezing large crowds into small spaces, using as little as possible, compared to the number of people. A high grade on either measure is to be welcomed, whilst lower grades suggest opportunities for improvement.
Figures for 2020 have been adjusted to account for reduced building usage during periods of lockdown.
Emissions per person-hour
Our emissions per person-hour in 2020 were rated as A+
The main reason for this high rating is that our Community Centre (outside of lockdown) sees plenty of use, and we’re aiming to keep this up for 2021.
Emissions per square metre
Our emissions per square metre in 2020 were rated as F
This rating isn’t as good as it could be, because our buildings have large open spaces which are difficult to heat efficiently. We’re looking at ways we can improve this rating for next year’s report.
In 2020 our estimated CO2 emissions were 18.7 tonnes
The majority of our emissions come from keeping our buildings warm. We’re thinking about ways we might be able to reduce this in future.
In 2020 we offset 0 tonnes of CO2
We have already started to change this in 2021, by offsetting some purchases of new equipment. We hope to offset more of our energy usage and activities in the future.
