Anyone with commercial buildings
What changes is not the modelling, it is who pays and who saves, and how many buildings arrive at once. Find the situation that matches yours.
Your situation
Whether you occupy the building or let it decides which measures are worth doing and who benefits.
Your sector
Where the building type itself changes what tends to be worth doing. Both are estates by nature, and both come in as one list.
Not for homes
Meridians models commercial buildings only. If you are a householder, the figures here will not apply to you and we would rather say so now.
Offices, warehouses, shops, pubs, hotels, light industrial, mixed portfolios. One building or a hundred, and a portfolio can arrive as a single list.
Start with what you have
Add your buildings and their energy data, and each measure is read against each one. It costs nothing.
