Most commercial buildings follow a familiar pattern. There are bare rooms, possibly offices, bathroom facilities, kitchen areas, break rooms, conference rooms, and the more spaces like these that are waiting to be finished once the final occupants move in. Other types of commercial buildings like hospitals care facilities, drug manufacturing, and pharmaceutical buildings need specialized infrastructure and mechanical systems to complete their intended functions. Whether these functions have to do with occupancy care, manufacturing, product creation, or testing and analysis of end products, the proper mechanical, electrical, and plumbing equipment must be selected to ensure the safety of the occupants.
With specialty commercial buildings where very specific tasks need to be completed, the mechanical, electrical, and plumbing systems need to match the level of complexity of the building. Where there are things like clean rooms and laboratories in a building, it takes a specialized set of systems to adequately process and manage the building functions. A laboratory has very specialized functions that produce unique and potentially hazardous waste, toxic chemicals, and manufactured pollutants that can create a combustible atmosphere if left unchecked in the laboratory. For this reason it is necessary to design and install the specialized equipment and systems to manage the expulsion and neutralization of these byproducts.
One such system required is the exhaust system. In standard applications you will find exhaust systems in kitchens, bathrooms, and anywhere else potentially hazardous materials can build up in the atmosphere of a structure. Both commercial and residential structures have exhaust systems in various rooms to help expel the byproducts produced by occupant activities through a series of fans, mechanical equipment, filters, blowers, ductwork, and other components that could make up an exhaust system.
Each laboratory will have it's own unique set of system requirements based on what the laboratory is producing and testing in the space. Consulting with an MEP engineer that has specialized knowledge in lab applications is highly recommended. The earlier you can consult with a professional the better. Consulting with a professional early on in the design process will lower your chance of mistakenly selecting the wrong equipment, drastically.
