Good afternoon, we're certifying a building that is 10% retail, 10% offices and 80% residential. We are unsure as to which rating system to choose, since the residential layout has not been completely defined in order to leave the possibility for future owners to modify it. Furthermore, the retail and office layout will not be defined until the tenants settle in. Could you advise us as to which rating system we can use? Core and Shall? New Construction? Thank you in advance for your help, please let us know if you need further details. Kind regards, Sandro
