The London Energy Map project is an attempt to find out more about real energy consumptions for buildings in London using data science.

We hope our work can enable efficient solutions towards Zero Carbon.

The issue.

There is a climate emergency.

London’s carbon emissions are dominated by buildings. A complex mosaic of individual buildings need to reduce their energy consumption and carbon emissions so London as a whole can achieve Zero Carbon by 2050.

But by how much and how? A fundamental issue is that few building owners know how much energy they use, and how much this needs to be reduced. The link between city-wide carbon targets, and individual energy consumption of buildings has not been made.

Our goals

As an overarching theme, we want to cultivate data driven solutions and culture in the building industry towards climate change objectives

In the first instance, we want to provide current estimates of operational energy in London buildings based on existing data

Once we know how much energy each building consumes, we will translate the net zero carbon ambition to a building level target (kWh)

Where we got to…

We have crudely built a predictive model for the domestic sector which calculates energy consumption based on a handful of inputs. For the non-domestic buildings, we summarised all the floor areas and used data-based benchmarks to estimate overall energy consumption in London. Have a look at our Project updates for our journeys in each analysis.

We have run out of time before we could achieve our second objective, to translate the targets to a building level… If you are interested to continue this work, please contact us!

For the remaining 2 months, we will focus on producing useful outputs from our findings, so watch this space!
