Okay, have a dormitory building renovation project that includes the following:

  • Is registered on the National Register of Historic Places (1880-era), so is technically exempt from energy code requirements.
  • Needs to improve over ASHRAE 90.1-2013 by 20% (per UFC 1-200-02 High Performance and Sustainable Building Requirements).
  • Is pursuing LEEDv4 BD+C (ASHRAE 90.1-2010)
  • Has existing HVAC system of air-cooled chiller with AHU's and VAV terminal units with reheat (gas-fired boilers). System may be replaced with new.
  • Renovation will include all new lighting and electrical.
  • Will include new window treatments. Opaque envelope improvements are yet unknown and may be minimal.

Curious how others would approach energy modeling for this...

  1. Build three models (Proposed, 90.1-10 baseline for LEED, 90.1-13 baseline for UFC) since the envelope requirements for baseline models changed in 2013?
  2. Attempt to comply with LEED requirements using LEED Interpretation ID#10481 and take the envelope baseline penalty?
  3. Something else?

which building energy modeling softwares are you familiar with? Both IES-VE and OpenStudio have tools for baseline / LEED automation.
