Insulation in a commercial building

Roof, wall or floor insulation reduces the heat a building loses, so the heating system has less to do. In a large single storey building the roof is usually where most of it goes.

The strongest cases are buildings that are being reroofed anyway, buildings with a heating system about to be replaced, and buildings with a rating problem.

It suits older stock, buildings with high heating demand, and any building where a heat pump is being considered, because fabric first makes the pump smaller and cheaper to run.

It suits you less where the building is barely heated, or where a lease makes fabric work impractical.

• -What insulation is there now, which the EPC and any construction records will indicate.
• -Whether other work is planned that opens the fabric up anyway.
• -Heated floor area and how the space is used.
• -Tenure. Fabric work is a landlord decision in most leases.

The figures Meridians models with. Your building replaces them with its own data as soon as we have it.

Installed costProvisional

from 30 to 90 per square metre

Provisional, scaled from domestic insulation costs rather than commercial proposals.

Reduction in heating demandProvisional

5 to 18 per cent

Provisional.

Both figures above are provisional. They are scaled from domestic data rather than taken from commercial proposals, so treat them as an indication rather than a price.

Cost leads with the low end. Payback leads with the longer one.

The card a client sees, rendered by the application itself.

• -It is done in isolation, when doing it alongside a reroof would have cost a fraction of the access.
• -The heating system is replaced first and sized to the uninsulated building, so it is oversized for the rest of its life.
• -Ventilation and condensation risk are not considered.

Fabric is a direct input to a non domestic EPC, so insulation can move a rating.
