2014 HVAC Design Calculations

The main objective of the HVAC design calculations project will be to provide correctly sized heating, ventilation and air conditioning systems for the building. The team is to calculate heating and cooling loads and design the selected HVAC system for the building, while demonstrating compliance with latest editions of ASHRAE Standards 55, 62.1, and 90.1. It is expected that students shall demonstrate this compliance by illustrating examples of this compliance in their illustrated calculations; points will be awarded for this demonstration with detail of compliance.  Also, the design of the building must comply with the Owner’s Project Requirements document that has been provided.

For this competition the owner has decided that he wants to use a Air Handling Unit for the lab space and Variable Refrigerant Flow systems for the remainder of the building. Thus, the HVAC System must use an air handling unit for the lab space and variable refrigerant flow systems for all other spaces.  Any entries not using these systems will be penalized. The use of alternate systems or comparison with alternate systems is not required by this competition and will not be taken into consideration during the judging.  The source of the cooling and heating for the lab unit is to be determined by the student design team, but must follow the standards and guidelines from ASHRAE and local code.

ASHRAE student teams may locate the office building in the capital of the students’ state, province or country, i.e., students from Mexico may use Mexico City. Building criteria and interior design assumptions are to remain the same for all building sites, with the exception of the climate information.

If the building requirements are not fully defined or need to be modified due to climate or other conditions, students should utilize the information within ASHRAE 90.1-2010 as their basis of assumption (all of these assumptions shall be stated by the student team).

It is suggested that the Student Design Team work together with a local consulting engineer and YEA members as mentors on this project. Your local ASHRAE Chapter Student Activities Chair will support you in this endeavor by providing willing mentors from its ranks in the consulting community to assist you, at your request. Contact Justin Ledford (ASHRAE Assistant Manager, Student Activities), for assistance with locating your chapter chair at jledford@ashrae.org.

Design Calculations Competition Submittal Requirements

The submission for the HVAC Design Calculations category must be in PDF format only!  No separate visual aids will be accepted (PowerPoint, YouTube, etc).  Deliverable presentation should only consist of a 35 page maximum technical report either Times New Roman or Arial font at 11pt minimum in PDF format only. 

Required technical information to be included in the PDF documents:

  • Cover sheet

  • Table of contents
  • References and Appendicies
  • Schedules for all major equipment components selected, including listed equipment efficiencies and demonstrated compliance to ASHRAE Standard 90.1
  • Mechanical floor plans showing general equipment layout and single line duct size and layouts, piping sizes and layouts, terminal units, diffusers, grilles, registers, thermostats, humidistats and any other pertinent devices or equipment. Include at least one detailed example of design detail in compliance with ASHRAE manuals
  • Schematic flow diagram indicating components and accessories and piping sizes and examples of how this system is designed in accordance with ASHRAE manuals
  • Heating and Cooling Load Calculations: Provide checksum reports for each System, design cooling and heating block load reports for selection of cooling and heating plants (refer to sample reports provided as an example)
  • Summary table of ventilation calculations to demonstrate compliance with ASHRAE 62.1
  • Illustrations of compliance to stated ASHRAE Standards
    • 55-2010
