Advanced Modeling Techniques for HVAC Systems
SSN 006

In this full day workshop-based class, students configure a series of advanced modeling scenarios. Included are workshops covering the process of eliminating unmet hours, optimizing the ASHRAE ventilation (OA) design for a multiple-zone application using the ASHRAE Standard 62.1 Ventilation Rate Procedure, configuring three different 100% OA systems (100% OA variable flow air system for laboratory make up, 100% OA VAV air system, and a standard 100% OA constant volume (DOAS) air system). Next we will configure VRF systems for both loads and energy modeling including heat pump and heat recovery applications. Also included are workshops on modeling of an air system that preheats with waste heat, warehouse heating systems with passive cooling, and a common boiler serving both domestic hot water and perimeter heating. Also included are workshops that cover new chillerbased heat recovery, setting up multiple energy conservation (ECM) alternatives, creating a template project, selecting pre-engineered packaged equipment to match load output results, use of multipliers at the space and air system level, diversity modeling, analyzing maximum % RH using ASHRAE DP weather data, understanding the CFM calculation based on user SAT inputs. We will cover use of the Wizards for space and air system creation and rapid operating costs. Students who complete this course have the ability to configure and model all the advanced HVAC scenarios mentioned here utilizing computer simulation software.

Who should attend this class

This class is for HVAC designers who have previous experience running Load and Energy software but wish to master the specific modeling configurations described above. A working knowledge of building design and computer skills is required.

Learning Objectives

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

• Define, diagnose and troubleshoot LEED unmet load hours for a typical LEED project
• Optimize the required ventilation air quantity using the ASHRAE Standard 62.1 Ventilation Rate Procedure
• Configure a 100% OA (DOAS) air system that tracks a variable exhaust application such as a laboratory
• Configure 100% OA VAV air system, and a stand-alone constant volume 100% OA system
• Configure a VRF system
• Model a heating only air system that provides passive cooling from ambient such as in a warehouse
• Merge data from multiple projects into one project, utilize Import HAP Project Data functionality
• Effectively use Wizards to enhance modeling productivity for preliminary design
• Review the requirements of a district/campus LEED project model
• Configure a LEED unconditioned space Check for maximum % RH for a zone
• Define when to use multipliers to increase productivity
• Determine how heating or cooling mode generates final fan airflow

Training Methods Used

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