Integrated Sustainability Approach

# How the services
work on one project.

20

Each service has its own deliverable, but they are not sequential and they are not independent. The energy model feeds the carbon inventory and the cost analysis. The daylight study changes the façade, which changes both. Certification evidence is a by-product of work already done. The matrix below shows where each discipline is active across a project.

Service | Concept | Design | Procurement | Construction | Operation
--- | --- | --- | --- | --- | ---
Green Building Certification |  |  |  |  |
Building Energy Modelling |  |  |  |  |
Daylighting Assessment |  |  |  |  |
Life Cycle Assessment |  |  |  |  |
Life Cycle Costing |  |  |  |  |
GHG & Carbon Accounting |  |  |  |  |
ESG Reporting & Advisory |  |  |  |  |

Where the services meet
Daylight → Energy → Cost

The shading study changes the cooling load in the energy model, which changes the operating cost in the LCC and the plant size in the capital cost.

LCA → LCC → Specification

The material comparison is run for carbon and for whole-life cost together, so the substitution is judged on both before it reaches procurement.

Energy → Carbon → ESG

The modelled and metered energy demand becomes the Scope 2 inventory, which becomes the disclosed emissions intensity in the ESG report.
