Energy Modeling What is energy modeling? Energy modeling software is an important design tool we use to analyze and improve building energy efficiency. When we design with an energy model, we test energy-saving strategies for occupant comfort, optimal return on investment, and to meet your energy efficiency goals. How can energy modeling help your project? It’s never too early to begin - from the earliest stages of design energy models help us make decisions about form, orientation, window layout, and materials that reduce monthly energy bills and mechanical system sizing. As the design progresses, we dive deep to explore different mechanical systems, lighting, control strategies, and more. We can even use energy modeling for existing buildings to test energy conservation measures such as lighting or envelope retrofits. What is your energy goal? If it is to build an affordable, energy efficient solution, then working with a firm that uses energy modeling will be a key step in achieving this goal.

Case Studies Infrastructure Improvements MEMORIAL MEDICAL CENTER | SPRINGFIELD, ILLINOIS This two-story 145,000 square foot addition to the medical campus central utility plant included high-efficiency heating hot water boilers, heat recovery chillers, and energy-efficient variable speed pumps and cooling tower fans. Through energy modeling and life cycle cost analysis, BSA arrived at a solution that allowed the modified central plant to reduce energy consumption by 20% despite increasing the size of the campus by 15%.
• 145,000 square foot addition to existing central plant • 20% reduction in energy consumption • 15% increase in campus size
McCourtney Hall NOTRE DAME UNIVERSITY | NOTRE DAME, INDIANA McCourtney Hall is a 220,000 square foot new construction multidisciplinary research building focused on pharmaceutical discovery. The building is connected to a campus chilled water and steam distribution system, so the energy model needed to account for systems inside the building and at the central utility plant. Additional modeled features include heat recovery chillers, LED lighting, and a high-performance building envelope. The energy model showed a 26% reduction in energy use, contributing to the building’s LEED Gold certification.
• 220,000 square feet new construction • 26% reduction in energy consumption • LEED Gold
Everitt Lab Renovation UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN | URBANA, ILLINOIS This project included the renovation of a building originally constructed in the 1940s and a central addition to the U-shaped structure. The new floor plan combines laboratory, classroom, and medical simulation spaces. Energy modeling was performed for LEED certification and showed a 30% reduction in energy use for efficiency features, such as a heat recovery chiller, lab exhaust heat recovery, variable air volume fume hoods, occupant and climate responsive controls, and LED lighting. By leaving the existing window frames in place where the addition meets the existing building, daylight reduces the need for electric lighting, and new double pane windows reduce HVAC energy use.
• 124,000 square foot renovation and 13,000 square foot addition • 30% reduction in energy consumption • Pursuing LEED Gold
