Load and Energy Calculation of Commercial Buildings for LEED® 4.0 Energy Analysis
SSN 005

This intense one-day class focuses on the LEED® Energy and Atmosphere Credit to Optimize Energy Performance. Advanced simulation techniques are applied to the Performance Rating Method for whole building energy simulation per ASHRAE/IESNA Standard 90.1 requirements. Training covers in-depth, hands-on application of baseline and proposed building energy analysis and includes development of creative HVAC system alternatives for more LEED-Energy points including the new LEED V4 tables and requirements. Students who complete this course have the ability to run simulation software for analyzing baseline versus proposed building models for LEED Energy and Atmosphere Credit, Optimize Energy Performance.

Who should attend this training

This course is for HVAC designers who use load calculation software to calculate heating and cooling loads in commercial buildings. A working knowledge of building design and computer skills is required.

Learning Objectives

At the conclusion of this course each student should be able to:

• Create the prescribed baseline building meeting all ASHRAE mandatory requirements
• Define and enter baseline building prescribed HVAC systems and min. efficiencies
• Create additional rotated baseline buildings for determining average energy use and cost
• Generate and interpret LEED report to determine EAc1 points
• Determine alternate design approaches to maximize LEED points

Training Methods Used

This course uses a combination of classroom lecture, videos, and demonstrations and workshops to present the material. Student’s achievement of the learning objectives is determined by successful completion of the workshops, and final written exam. Workshops are instructor guided exercises using the procedures taught in the lectures.
