When/why should you submit a LEED Interpretation?
Submit a LEED interpretation - This type of formal inquiry is relevant to many projects. These are examples of inquires that, after receiving a Project CIR, would also result in a LEED interpretation if the project team opted into the LEED-interpretations process.
When/why should you submit a CIR?
Submit a project CIR - If a project team needs guidance on an issue before submitting for certification review, the project CIR process is available to them. The project CIR will be determined by a GBCI Certification Reviewer familiar with the project's specific circumstances. The advantage of a project CIR is that the timeline for a ruling is relatively quick, and the project team can have certainty about the applicability of their strategy early in the design or implementation process.
Which of the following apply to alternate water uses for projects pursuing WE Credit Outdoor Water Use Reduction?
Testing site-derived alternative water to confirm its suitability for irrigation uses is recommended not mandated. Salinity is one concern. Irrigation with saline water in an arid environment causes salt buildup in the soil, eventually degrading it. Condensate and cooling tower blowdown in particular may have salinity levels precluding use for irrigation. A second concern is that alternative water supplies must be stored until needed for irrigation; the timing and reliability of the supply must be assessed.

A new construction project will include a unique process resulting in non-regulated load savings (not included in ASHRAE standard). The project is using whole building energy simulation to earn EA Credit Optimize Energy Performance. Which of the following is true regarding how these savings can be documented and factored in using energy simulation?
The exceptional calculation method can be used to document load savings. In ASHRAE 90.1-2010, Appendix G, Section G2.5, an exceptional calculation method (ECM) is used when the simulation program that is generating the energy model is incapable of modeling a certain design, material, or device of the proposed design. LEED has adopted and slightly expanded use of exceptional calculations to cover any savings claimed for a nonregulated load, defined as any building load, end use, or control without an Appendix G baseline modeling requirement that allows the load, end use, or control to be modeled differently in the proposed and baseline buildings.

A whole building energy simulation resulted in a baseline building performance of $100,000 for a new construction project. What minimum improvement in building performance is needed for LEED certification?
The question tests your knowledge on EA Prereq Minimum Energy Performance. Projects should demonstrate an improvement of 5% for new construction, 3% for major renovations, or 2% for core and shell projects in the proposed building performance rating compared with the baseline building performance rating. Since the project in our question is "New Construction" - a 5% improvement would be $5,000 ( $100,000 x 5%). Remember thresholds for CS and Major renovations too (5% for NC,3% for Major Reno.,2% for CS). The same question could be asked in a different way to test your knowledge on EA credit optimize energy performance (6% for NC, 4% for Major Reno.,3% for CS)
