WHAT MAKES EV0
THE UK'S MOST SUSTAINABLE WORKSPACE?

Net zero carbon in both construction and operation
Built using a unique mass timber frame that captures and stores carbon
100% electric, with all energy generated on site or provided by Bruntwood Group’s co-operative wind farm

Ev0 will be Bruntwood’s first project to meet the LETI 2020 design targets for ‘upfront carbon’, RIBA’s 2025 targets for whole life carbon and the UKGBC's Paris Proof operational energy use targets. The building is also targeting NABERS 5.5 stars and BREEAM Excellent ratings. We are exercising complete transparency with our development figures - see below for more details.

CARBON NEUTRAL
IN BOTH:

Upfront carbon

This is the total carbon generated to produce a built asset, including emissions caused by extraction, manufacturing, transportation and assembly.

124kg C02e/m2 of the gross internal area (GIA) when taking carbon sequestration into account.
516kg CO2e/m2 (GIA) without taking sequestration into account, which is 14% lower than the 2020 LETI design target of 600kg CO2e/M2 and c.65% lower than the RIBA 'Business as Usual' target of 1400kg CO2e/m2 (GIA).
The Whole Life Carbon assessment for the development is currently calculated at 871kg C02e/m2 (GIA), below the RIBA 2025 target of 970kg C02e/m2 (GIA), with the ambition of meeting the RIBA 2030 target of 750kg C02e/m2 (GIA) during design development.

Operational carbon

This is the amount of carbon emitted during the operational or in-use phase of a building, including daily use, management and maintenance of the structure.

The base building operational energy use has been calculated at 28kWh/m2/year (GIA), which is slightly below the UKGBC’s Paris Proof Target of 30kWh/m2/year (GIA).
Occupier energy has been assumed at 35kWh/m2/year (NIA) in line with the UKGBC’s Paris Proof Target, whole building energy intensity is at 54kWh/m2/year (GIA), again slightly below the UKGBC’s Paris Proof Target of 55kWh/m2/year (GIA). The above does not take into account any contribution from onsite energy generation, which Ev0 will provide.
If the onsite generation is included, i.e. if only energy demand imported from the grid is assessed, the operational energy demand for the building is calculated at 5kWh/m2/year (GIA), with the UKGBC Paris Proof 2035-2050 target at <55kWh/m2 (GIA). The remaining energy demand of the building will be met by green energy generated from Bruntwood’s co-operative wind farm.

FRAMED IN TIMBER

The most unique part of Ev0 is its mass timber frame. In order to reach our goal of creating the UK's lowest carbon workspace, we will use mass timber to capture carbon. This process is called carbon sequestration.

Buildings created with traditional material, like steel or concrete, have a significant carbon impact on the environment. Ev0’s mass timber frame will have a positive effect by capturing carbon from the atmosphere and locking it away - in the same way a tree does.
