1. The project pertains to a fit-up of only the 3rd floor of a multi-floor building. The HVAC scope of the renovation does not include changes to the water-side components and only affects the air-side components. i.e. a new AHU, ERV, HLR and VAV boxes are installed, however, the chiller and boiler feeding the hydronic lines are existing (used by the whole building). How do we reflect the existing equipment in the spreadsheet when the spreadsheet specifically calls for baseline/proposed equipment information? Specifically referring to the following sheets: Service Water Heating, General HVAC, Air-Side HVAC and Water-Side HVAC.
  2. Similarly, how do we portray this in the energy simulation? Do we use ASHRAE 90.1 and auto-size the chiller/boiler to strictly the 3rd floor or use some other methodology to incorporate the existing equipment specifications?
  3. Low-flow fixture consideration/does it apply to this type of project?
