Why the EUI in the RFP?

- 3. HIGHLY DESIRABLE - have influence on the recommended design; if not included, trade-offs should be made clear Photos courtesy of University of Chicago PROJECT GOAL LIST: Project goals help design teams prioritize their focus on the MEP and building performance design. Goals are categorized in three main sections: • Maximum energy target of 65 KBTU/gsf annually; lower is preferred • LEED NC Silver Certification • Superior occupant comfort • EnergyStar certified building MISSION CRITICAL - these are deemed critical to project success IF POSSIBLE - influence recommended design and are considered highly beneficial if included in the solution • Living Building full certification • Net Zero Energy Design • Maximum energy target of 55 kBtu/gsf annually; lower is preferred • Passive design strategies (i.e. daylighting, passive solar heating, etc.) • Ease of maintenance • Visual displays of current energy efficiency • Exceed LEED NC version 4, Silver Certification RFP LANGUAGE

- 7. Define an energy requirement Lack of clarity with unbounded interpretation. Rating schemes help resolve this, but do not drive a certain metric. Often this is a comparison between simulated results. There is very little opportunity to verify actual savings. This is a measurable target; requires up-front research to establish a realistic benchmark. Sustainable building 30% savings over energy code An annual energy use intensity (EUI) of 45 kBtu/sq ft/year A B C Same budget Same budget Same budget Project energy goals

- 12. Add context and clarity Proposed project size
- 13. Approach • Benchmark • Yours, the owners, peers, industry targets • Communicate financial implications of the owner’s energy goal • Create 2-3 packages – not a list of one-offs • Be aware of the most sensitive variables • Avoid language around ‘guarantee’
- 14. No guarantee Not an energy performance contract • Need all three parts – design, construction, and operations
