      Modelling WWHRS & Showers in Non-residential (SBEM Methodology)

      Waste Water Heat Recovery Showers is a new feature in SBEM v5.6a. The functionality is available in Part L2 (2013) England, Part L2 (2014) Wales, and Section 6 / 63 (2015) Scotland. WWHRS is not available in any DSM version of UK compliance.

      Modelling WWHRS under SBEM is similar to modelling under SAP

      SBEM 2013 WWHRS modeling screen
      WWHRS can be accessed in the UK NCM data wizard in the Showers tab. This tab defines:
      • Number of shower types (by using the add/ remove button to increment or decrement)
      • Whether the shower has a heat recovery system WWHRS Present?
      • Whether the shower is located over a bath (cubical otherwise) Shower Over Bath?
      • If heat recovery is present, a definition of it’s efficiency Heat Recovery Efficiency
      • Whether the shower is pumped (so electrical energy can be tracked Uses Pump
      • If the shower has a pump, a definition of pump power Notional Pump Power (W)
      • Lastly how many individual showers of that shower type are in the building Units  

      Currently, WWHRS is not available in any DSM version of UK compliance. However, workarounds do exist and we have described these in this article

      WWHRS (DWHR) is available on IES VE - This is implemented in their ApacheHVAC tool and a user can configure the system there See article here:
