The mechanical plan specifies the design of or the modifications to the mechanical system, ductwork layout and dimensions, mechanical equipment location, damper locations, design air-delivery rates, diffuser locations, thermostat locations, and supplemental cooling systems if required.
Why is HVAC system important in architectural plan?
HVAC systems are designed to allow air to circulate between rooms or even throughout large areas of a building. This means that architects will often place vents strategically in their designs, both to maximize the flow of air for heating or cooling purposes and so that cleaning units can do their job properly.
What are the 2 types of HVAC system design?
Each type of HVAC system falls into one of two categories: ducted or ductless. In a ducted system, the main unit pushes air through a series of air ducts to cool or heat a building. Ductless systems, on the other hand, lack air ducts and use alternative methods to distribute treated air throughout a space.
Why HVAC design is important?
Heating, Ventilation, and Air Conditioning (HVAC) systems account for 39 percent of the energy consumed in commercial buildings. Industries that use or emit harmful chemicals rely on customized designs to help increase efficiency and keep emissions within Environmental Protection Agency (EPA) guidelines.

What is HVAC and its purpose?
The main purposes of a Heating, Ventilation and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in schools.
What is the most important part of HVAC?
The heat exchanger is the most important part of your heater or furnace, because it's the tool that heats the air. Typical, furnaces pull air in from the outside. The heat exchanger heats the air quickly, and the air is blown into your home.
What are HVAC items?
HVAC is an acronym for heating, ventilation and air-conditioning systems. This includes products like furnaces, air handlers, packaged units, heat pumps, air conditioners and whole-home ventilators.
What is the HVAC unit inside the house called?
When you look at your HVAC system, you only see two boxes – one that sits outside your house, and the other inside your home in the garage, attic or basement. The outside components box is called the condenser while the inside box is the air handler.
What are the 2 types of HVAC system design?
Each type of HVAC system falls into one of two categories: ducted or ductless. In a ducted system, the main unit pushes air through a series of air ducts to cool or heat a building. Ductless systems, on the other hand, lack air ducts and use alternative methods to distribute treated air throughout a space.
1. HVAC Layout Drawing
The layout drawing shows the HVAC equipment layout. It is the primary type of HVAC drawing that you’ll be reading a lot. Typically, a high-rise building project consists of around 30 pages of layout drawings with each page representing one floor.
2. HVAC Schematic Drawing
The schematic drawing is the second most important type of HVAC drawing. Usually, a medium-scaled project has a few schematic drawings with each drawing representing one HVAC system.
3. Installation Details for HVAC
Installation details are drawings that show the installation method and specification. They are usually issued by design engineers or consultants. Nonetheless, they are based on international standards such as SMACNA (for ducts).
4. Single Line Diagram for HVAC Panels
Control panels are essential for the HVAC system and hence, single line diagrams are inevitable. Single line diagrams show the wiring details of the control panels. Specifications such as cable sizes and breaker sizes are written in single line diagrams.
Other Drawings Relevant to HVAC
Opening Drawing – Used to show wall and slab opening details for pipes and ducts penetration.
