up-icon.pngWhat Is Covered

To make informed decisions, it is necessary to have a basic understanding of the commercial HVAC design process, including how seemingly different elements interact, and how to combine the basic design steps to complete the required calculations. Maria’s Restaurant is a case study that details by example the approach needed to succeed in developing commercial designs. A restaurant design was selected for the guide and workbook because restaurants are a more complicated subset of commercial applications. Once you understand a restaurant design, you will be able to apply the basic design requirements to less complicated retail spaces—such as beauty parlors, pet shops, and dry goods stores—as well as office areas. 

Whether you are reviewing a permit application or preparing a proposal as a commercial HVACR contractor, you need to understand the basic process covered in this Guide & Workbook. 

Maria’s Restaurant provides a possible design sequence for:

  1. Calculating the heating and cooling requirements for a restaurant.
  2. Selecting the heating and air conditioning equipment needed to meet those requirements.
  3. Designing a duct system to deliver the correct amount of conditioned air.
  4. Developing building pressurization plan, and an airflow plan for comfort and energy savings.
  5. Choosing the correct grilles and registers for optimal mixing of conditioned air for maximum comfort.

Maria’s Restaurant also covers some common pitfalls designers encounter when integrating the design and equipment selection processes.  The Workbook & Guide provides an overview of the process intended for general audiences.  Additional sections provide the process details for those who want to dig deeper into the design and equipment selection process.
