<p>Sarah Peterson: </p> <hr /> <div>= Aim and benefits =<br /> <br /> To reduce potable water demand through the installation of energy efficient sanitary fittings, rainwater collection and water recycling systems.<br /> <br /> Up to 5 credits are available plus an additional credit for exemplary performance.<br /> <br /> = When to consider =<br /> <br /> Design Stage RIBA Stages 3-4<br /> <br /> = Step by step guidance =<br /> <br /> Credit Wat 1 is an assessment of the efficiency of the buildings water consumption compared to a baseline performance standard.<br /> <br /> Using the BREEAM Wat 1 Calculator Tool the water consumption (litres per person per day) is assessed to suit the building type and credits awarded accordingly.<br /> <br /> The following components are included in the assessment and must be included within the calculation where specified in the project:<br /> <br /> * WCs<br /> * Urinals<br /> * Taps (wash hand basins and where specified kitchen taps and waste disposal unit)<br /> * Showers<br /> * Baths<br /> * Dishwashers (domestic and commercial sized)<br /> * Washing machines (domestic and commercial or industrial sized)<br /> <br /> If any Rainwater or Greywater recycling systems are proposed details must also be included.<br /> <br /> There are two methods to assess the credit:<br /> <br /> # Standard Method<br /> # Alternative Method<br /> <br /> == Standard Method ==<br /> <br /> The standard approach is the default method for calculation.<br /> <br /> It uses the buildings actual component specification and default usage patterns for the building type and its activity areas. The output is compared with the same output for a baseline component specification and the percentage improvement used to determine the number of BREEAM credits achieved.<br /> <br /> The standard building types are:<br /> <br /> * Office<br /> * Retail<br /> * Industrial<br /> * Education<br /> <br /> == Alternative Method ==<br /> <br /> If the development does not meet the standard building types the alternative method can be used.<br /> <br /> Using the other buildings tab the performance level of each applicable component is assessed. This compares the actual specification for each component type with the table of water efficient consumption levels by component type (Table 36 within the BREEAM manual) to determine the level of performance for each type.<br /> <br /> Note that the volumes quoted are maximums for that level and the % WC or urinal flushing demand is a minimum for that level.<br /> <br /> == Average Flow Rate Calculator ==<br /> <br /> The Wat 1 Calculator tool has a tab to calculate the average flow if there are various specification types and flow rates for each component type across a development.<br /> <br /> == Effective Flush Volume ==<br /> <br /> For WC's this is calculated as follows:<br /> <br /> The effective flush volume of a single flush WC is the volume of water used for one flush.<br /> <br /> The effective flush volume of a dual flush WC is the ratio of full flush to reduced flush.<br /> <br /> This is taken to be one full flush for every three reduced flushes for non-domestic buildings and one full flush for every two reduced flushes in domestic (residential) buildings/areas.<br /> <br /> The effective flush volume can therefore be calculated as follows, using a 6/4 litre dual flush volume WC as an example:<br /> <br /> Non-domestic:{(6 litre x 1)+(4 litre x 3)}/4 =4.5 litre effective flushing volume<br /> <br /> = Questions to ask while seeking compliance =<br /> <br /> Can the credit be assessed using the standard approach or does the alternative method need to be used?<br /> <br /> Has the sanitary ware been selected or specified yet?<br /> <br /> Are there any Rainwater or Greywater recycling systems proposed?<br /> <br /> Who will be responsible for the specification of the sanitary ware including taps and showers?<br /> <br /> If detailed design has not been undertaken can target flow rates and flush volumes be set and included within a performance specification?<br /> <br /> = Tools and resources =<br /> <br /> BREEAM Manual<br /> <br /> BREEAM Wat 1 Calculator Tool<br /> <br /> = Tips and best practice =<br /> <br /> This BREEAM issue has minimum standards and at least 1 credit must be scored for this issue for Good, Very Good or an Excellent rating. 2 Credits must be achieved for an Outstanding rating.<br /> <br /> Due to the minimum standards this BREEAM issue should be reviewed as soon as possible to ensure the final BREEAM rating can be achieved.<br /> <br /> Depending on project procurement the design team may not select the sanitary ware and fittings. In this case it is recommended that the target flow rates and flush rates in order to achieve the required credits are detailed within a performance specification or contractors prelims document to ensure that they are met.<br /> <br /> Manufacturers information is generally the best location to find the required flow rates and flush volumes. The design team should provide this information to allow the calculator tool to be completed.<br /> <br /> At pre-assessment and early design stage the specification of the sanitary ware may not be complete, an estimation of the likely credits that can be achieved can be calculated with the following tables found within the BREEAM Manual, however a full calculation using the calculator tool should be carried out as soon as the information is available to verify the amount of credits that can be achieved.<br /> <br /> [[File:Untitled.jpg|link=File:Untitled.jpg]]<br /> <br /> = Typical evidence =<br /> <br /> === Design Stage ===<br /> <br /> BREEAM Wat 1 Calculator Tool<br /> <br /> Water Services drawings showing all water consuming equipment<br /> <br /> Sanitary ware schedule complete with flow rates and flush volumes<br /> <br /> Confirmation any grey or rain water systems are specified and installed to the relevant Building Standards.<br /> <br /> === Post Construction Stage ===<br /> <br /> BREEAM Wat 1 Calculator Tool<br /> <br /> Water Services drawings showing all water consuming equipment<br /> <br /> Sanitary ware schedule complete with flow rates and flush volumes<br /> <br /> Manufacturer’s literature for all sanitary ware complete with flow rates and flush volumes<br /> <br /> BREEAM assessor survey evidence.<br /> <br /> Confirmation any grey or rain water systems are specified and installed to the relevant Building Standards.<br /> <br /> === Rainwater and Grey water ===<br /> <br /> The requirements are:<br /> <br /> Rainwater: In accordance with BS8515 ‘intermediate approach’:<br /> <br /> 1.

The passive design analysis must include an analysis of free cooling and identify opportunities for the implementation of free cooling solutions.<br /> <br /> The building must then use any of the following free cooling strategies to award the free cooling credit:<br /> <br /> * Night time cooling<br /> * Ground coupled air cooling<br /> * Displacement ventilation (not linked to any active cooling system)<br /> * Ground water cooling<br /> * Surface water cooling<br /> * Evaporative cooling, direct or indirect<br /> * Desiccant dehumidification and evaporative cooling, using waste heat<br /> * Absorption cooling, using waste heat<br /> * The building does not require any significant form of active cooling or mechanical ventilation (i.e.. naturally ventilated).<br /> <br /> The free cooling measure proposed must be verified and the energy reduction shown when compared to a mechanical system.<br /> <br /> This is generally carried out via dynamic simulation modelling with the free cooling energy demand compared with a mechanical system and the associated energy savings reported. This will require the engineer to run two models - one the proposed design and the other a baseline to measure savings. The details of both should be included within the model report.<br /> <br /> Free cooling is an enhanced passive design method that requires engineering design and modelling to demonstrate its effectiveness.<br /> <br /> = Questions to ask while seeking compliance =<br /> <br /> What free cooling strategy is proposed?<br /> <br /> Will this strategy be implemented across the whole building? The credit cannot be award if free cooling is only utilised in part with mechanical cooling systems included elsewhere.<br /> <br /> Who will carry out the analysis and what are qualifications do they have?

Small IT rooms and lift motor rooms are excluded.<br /> <br /> Mechanical ventilation may only be used for small areas, e.g.. for kitchenettes and toilets.<br /> <br /> Free cooling appraisal can typically be assessed using dynamic simulation modelling such as IES or TAS.
