Setting occupancy levels will not effect the hot water consumption levels. Note that some activity types can have&nbsp;a relatively high HWS requirement; for e.g. Changing facilities in training centres.</span></p> <p style="text-align:justify;"><span style="font-size:small;">Further consideration; If you are find that modifying your HWS system, or&nbsp;adding a solar system to the HWS generator for a zone but not seeing changes to results, this could be that you have the system assigned to a zone that has no requirement for a HWS system. For e.g. A residential care home, HWS systems should be assigned to zones containing Bedrooms rather than zones dedicated to Bathrooms.</span></p> <hr style="width:100%;" /> <p style="text-align:center;"><span style="color:#800000;"><strong>For an important note on the PartL calculation, please <a href="/products/building/performance/w/building_performance__wiki/15986.an-important-note-on-the-partl-calculation.aspx"><span style="color:#800000;">click here</span></a></strong></span></p> <hr style="width:100%;" /> <h1>See Also</h1> <p><a href="/Products/w/Products__Wiki/product-technotes-and-faqs.aspx">Product TechNotes and FAQs</a></p> <p><a href="/Products/Building/w/Building__Wiki/building-product-technotes-and-faqs.aspx">Building Product TechNotes And FAQs</a></p> <p>&nbsp;</p> <h1>External Links</h1> <p><a title="Bentley homepage" href="http://www.bentley.com/">Bentley homepage</a></p> <p><a href="http://www.bentley.com/en-US/Products/Hevacomp+Mechanical+Designer/">HevacompMechanical Designer</a></p> <p><a href="http://appsnet.bentley.com/kbase/">Bentley Technical Support KnowledgeBase</a></p> <p><a href="http://lms.bentley.com/">Bentley LEARN Server</a></p> <h1>Comments or Corrections?</h1> <p>&nbsp;Bentley&#39;s Technical Support Group requests that you please confine any comments you have on this Wiki entry to this &quot;Comments or Corrections?&quot; section.
