2018 HVAC Design Calculations

The main objective of the HVAC design calculations project is 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 the 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 details 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 variable air volume (VAV) air handling unit (AHU) for the building. Thus, the HVAC System must use a VAV air handling unit for all the spaces.  Any entries not using this system 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 VAV AHU is to be determined by the student design team, but must follow the standards and guidelines from ASHRAE and local code.

Assume the building envelope meets the recommendations of ASHRAE 189.1. All internal loading is as described in this OPR. Assume the building is oriented as shown on the schematic plan provided by the Owner.

ASHRAE student teams must locate the building in Istanbul Turkey near Arnavutkoy. DO NOT MOVE THE BUILDING TO ANOTHER LOCATION, IT MUST BE LOCATED IN Istanbul Turkey near Arnavutkoy. Teams that relocate the building to another location will be disqualified.

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 Katie Thomson (ASHRAE Assistant Manager, Student Activities), for assistance with locating your chapter chair at KThomson@ashrae.org.
