Generation offsets demand
PV generation lowers the building emission rate against the notional building. Capacity, orientation and shading all feed into the model.
SBEM solar compliance,
backed by evidence.
Solar PV and storage specifications for commercial, industrial and mixed-use developments under Part L2. We size solar and storage to the building's modelled demand, work alongside your SBEM assessor and M&E consultant, and hand over the documents building control and tenants expect.

This page is for commercial developers, design and build contractors, architects and M&E consultants working on offices, industrial units, warehouses, retail and mixed-use schemes. Part L2 sets the energy standard for new non-domestic buildings. In the SBEM calculation, rooftop solar PV can make a measurable difference to the building emission rate.
We get involved at design stage, covering array capacity and layout for the roof form, structural and roofing coordination, inverter and storage strategy, and the SBEM inputs that go with them. We manage the G99 application to the DNO, which can be a long-lead item, and work with the M&E design team so the system fits neatly with the building services.
At completion we hand over the building with MCS certification, commissioning records and monitoring. We can then stay on as the operations and maintenance provider for the landlord or tenant.

02. How solar affects SBEM
How solar PV affects
How solar PV affects
the SBEM result.
Roof form matters
Flat, pitched and sawtooth roofs need different mounting and layouts. We design for the structure and the roof warranty as well as the yield.
Storage strategy
Storage may not change the SBEM result, but it can strengthen the operating case for the occupier through peak shaving, resilience and tariff optimisation.
Explore battery storageEV infrastructure
We design Part S charge-point requirements and future fleet demand into the electrical infrastructure from day one.
Explore EV infrastructureSolar carports
Where roof space is limited, carports over the car park add capacity and give shelter.

MCS certificates and commissioning records support building control and the as-built assessment.

07. SBEM FAQs
Questions commercial developers
Still have a question?0330 043 1047 Questions commercial developers
often ask us.
How much solar do we need to pass Part L2?
It depends on the building, its services and the rest of the specification. We work with your SBEM assessor to size the array to the compliance gap and the roof.
When should the DNO application go in?
As early as possible. G99 approval can be a long-lead item and may set export limits that affect the design, so we submit it at design stage.
Can you work with our roofing contractor?
Yes. We coordinate mounting, penetrations and warranties with the roofing contractor, or provide roofing through our own crew.
Who owns and operates the system after completion?
That is for the developer, landlord and tenant to agree. We provide monitoring and O&M to whichever party takes it on.
Can you provide the inputs our assessor needs?
Yes. We supply capacity, orientation, inverter details and layout in the form the SBEM calculation needs.
Do you work on shell and core as well as fit-out?
Yes. We can deliver the renewables as part of the base build or as tenant works, and agree the split of responsibilities with the developer and the occupier at design stage.
What if the roof is too small or unsuitable for solar?
We look at the roof structure, warranty and available area first. Where roof space is limited, solar carports over the car park can add capacity, and we can include them in the same feasibility study.
Does adding battery storage affect the grid application?
It can. Batteries and inverters above the threshold need a G99 application before connection, so we include any planned storage in the DNO application from the outset.
