Within the context of Green Due Diligence (GDD) an existing building can be evaluated for sustainability in addition to its engineering services and structural condition through Technical Due Diligence – (TDD).
In addition the evaluation of Energy- and Water Consumption, Room Air Quality, Accessibility, Transport Connections, Maintenance Plans, Monitoring etc. is taken into account.
Green Due Diligence is often based upon the requirements of a certification system for existing buildings.
As required an evaluation can be developed for a project specific criteria profile that, for example, takes into account the sustainability targets of a portfolio strategy.
