We are needing to go down the route of Case 4 where there are facilties in landlors and tenant areas but we can only pursue the WEp1 which is fine. However out of our 10 floor project toilets are only being installed on 2 of the floors - for a gym with showers and a new disabled access WC plus one for catering. The FTE for the building is 1745 with 233 visitors - should i just use these figures (which are automatic from the project occupancy details template) or reduce them to 20% (for the 2 floors) but how can that be included in the template? can anyone help thanks

Per Appendix A in the Water Use Reduction Additional Guidance document dated December 1, 2009 (Updated August 16, 2010), Case 4 is applicable to those projects that have fixtures and fittings both within the tenant space and outside of the tenant space. As you indicated, the project is only eligible to pursue WEp1 since water savings can only be claimed for the fixtures and fixture fittings located inside the tenant space. Since this is a CI project, the FTE and transient occupant count of the tenant/project space would be used to calculate the water savings, not the FTE and transient count of the entire building. Thus, if you input the FTE and transient occupant count for the project space and only include the fixtures and fittings that are located inside of the tenant space, you should be able to determine the project’s water savings for WEp1.

The 10 floors is the project scope (there are another 15 in the building) but only two of the 10 have toilet facilities within the scope. The tenants on the 8 other floors will have to use the landlord toilets (outside of our scope). Do you think that its sufficient to reduce the FTE to 20% and do the calcs on that basis - I assume that a narrative will need to be included to do this as well. thanks
