Building Energy Modeling

Building energy modeling is a simulation process used to evaluate how a building consumes energy under current and proposed conditions. Whether you’re planning an energy-efficient retrofit or need to demonstrate savings for financing, energy modeling provides data-driven insights into how each Energy Conservation Measure (ECM) will perform. It helps prioritize upgrades, estimate ROI, and support compliance with utility or incentive program requirements.

Optimized investment in your building’s performance

LEED

Energy Modeling is a prerequisite for LEED Certification. The largest number of LEED points (19 out of 110) are available through the Optimize Energy Performance supplementary credit. You need an experienced team who can properly build your energy model to maximize the points available for this credit.

Life-Cycle Cost Analysis

Many states require a Life-Cycle Cost Analysis (LCCA) for any new or retrofit construction on state-owned buildings. They may also require a LCCA on state leases of private buildings. We can provide you with a building energy model and proper report to meet all state requirements for LCCA on these state facilities.

Walker Blue provides building energy modeling for all purposes including LEED, life-cycle cost analysis (LCCA), and energy conservation measures (ECMs).
