Yes, projects applying Option 1: Tenant-Level Energy Performance Compliance, and regulated by ASHRAE Standard 90.1-2013 or IECC 2015 may document achievement of LEED v4.1 ID+C EA Prerequisite Minimum Energy Performance and LEED v4.1 ID+C EA credit Optimize Energy Performance as described below:
Comply with all mandatory provisions of ASHRAE Standard 90.1-2013 or IECC 2015 for elements within the project scope of work.
AND
Demonstrate a Percentage improvement in the Proposed Building Performance beyond the Baseline Building performance in accordance with ANSI/ASHRAE/IESNA Standard 90.1-2013, Appendix G.
Calculate the Baseline Building Performance, Proposed Building Performancet, and Percentage Improvement using metrics of cost and greenhouse gas (GHG) emissions. For each energy source serving the project, the GHG emission factors must be identical for the Baseline and Proposed building models.
The LEED prerequisite Percentage Improvement requirements may be demonstrated either using metrics of cost from Table 1 or greenhouse gas (GHG) emissions from Table 2. LEED points are calculated based on the project percent improvement for cost and GHG emissions. Total points have been divided equally between the metrics of energy cost and greenhouse gas emissions. Points are awarded according to Table 1 and Table 2.
For project percent improvement for the cost metric, on-site renewable energy may be subtracted from proposed energy cost prior to calculating proposed building performance per ASHRAE Standard 90.1-2013 Section G 2.4.1.

On-site renewable energy may be subtracted from proposed greenhouse gas emissions prior to calculating proposed building performance per ASHRAE Standard 90.1-2013 Section G 2.4.1. New off-site renewable energy as defined in EA credit Renewable Energy may be subtracted from proposed greenhouse gas emissions prior to calculating proposed building performance.
