Good Afternoon,
I have completed multiple WSUD's reports, including establishing water efficiency calculations for new dwellings in Melbourne Australia.
While the framework/policies for water sustainability urban design may be different in the UK compared to Australia, the process of undertaking Water Efficiency Calculations is fundamentally the same.
I have already gone through and familiarised myself with the England Building Regulations (2010) - Part G2, as well as the Water Efficiency Calculator (governments national calculation methodology) as part of my due diligence in bidding for this project; and strongly believe i can assist you with this.
In order to complete the calculations and issue you with a report, I would require a substantial amount of information regarding your sanitary appliances and tap-ware/fittings, but we can discuss this over chat.
Further note that i am an accredited engineer through recognised qualifications via the Washington Accord and EUR-ACE; and can sign off at the end of a report if needed.
I look forward to hearing from you.
Regards,
Sabastian.
