The seconds are ticking down for my first attempt at PDD. I’m currently going through HVAC systems with my ARE Study Group (hi guys!) and I said I would come up with some questions on HVAC selection for different building types. I used the Architect’s Studio Companion to put these questions together.
Brad Pitt is currently searching for a small two bedroom bungalow in a climate where the main heat loss is through the building skin in the winter. He is a big advocate for going green and wants a system that is sustainable. What system should he select to heat the building?
The Tavares Continental Hotel Suites wants a new HVAC unit to service their kitchen and laundry spaces in an existing hotel that they are renovating. This system should provide heating and cooling, and plenty of fresh air. They want an enclosed system that can utilize the overheated areas to heat the underheated areas of the hotel. Cost is not a primary concern. Which system should the hotelier go for?
Torrential Inc. is looking to expand their research campus with a new laboratory. They are looking for an HVAC system which provides heating and cooling, with good humidity control and efficiency. They would prefer a quiet system that won’t interfere with their research work, with a reduced risk of mold which could contaminate their samples, and can provide them with lower ceiling to floor heights. To save on energy costs this system will be tied into a geothermal exchange. What system should they choose?
You have been engaged by a developer, the Yu Chen & Associates Construction Group, to provide a design for a hotel. The system needs to have low intial costs, with no central equipment, piping or ductwork. Due to the nature of the building operations, they would prefer to have lower operating costs as well. Which HVAC system should the architect select?
The American University Washington would like to create a new 6 story Economics Building dedicated to one of their alumni, Ms. Manisha Singh, the current Assistant Secretary, Economic & Business Affairs in the U.S. Department of State. American University has stressed the need for a quite system, so as not to interfere with the lectures. The university has requested that system provide a low first cost with low maintenance requirements to provide room in their budget for higher quality finishes. What HVAC system would you recommend?
For all answers, reference the Architect’s Studio Companion sections on HVAC selection. This is one of my favorite books on this topic, as it deals with system selection in a very straightforward way.
- Passive Solar Heating, refer to page 228
- Closed Loop Heat Pump System, refer to page 181
- Active Chilled Beam System, refer to page 178
- Packaged Terminal Unit Systems, refer to page 184
- Variable Air Ventilation System, page 174
