HAP Master Course with Complete Projects

Explore all air distribution systems, their advantages, disadvantages, and applications, with a focus on constant air volume and variable air volume, including single duct single zone systems.

Explores single duct constant volume multi-zone and single duct variable volume multi-zone systems, plus dual duct constant volume or vav, with reheat coils and vav boxes, outlining advantages and applications.

Learn the fundamentals of heating and cooling load, the heat sources that affect it, and how partition, infiltration, exfiltration, u-factor, and solar heat gain coefficient shape hvac design.

Install Hap software by first installing iChat X builder, then run the Hap 4.5 setup, choose universal region, install to the C drive, and start a new project.

Analyze the architectural plan to identify rooms for conditioning, determine orientation, and calculate cooling load using area in square meters times 0.07 for commercial buildings.

Prepare a space sheet for heat load calculation by compiling room details, building envelope, occupancy, exposure walls, windows, ventilation, and internal loads for input into heat load software.

Learn to add weather data in HAP per ASHRAE 2021 for a Hyderabad project by entering climate parameters—latitude, longitude, elevation, design temperatures, wet/dry bulb values, and time zone.

learn to add weather data in hap software per esri databook 2017, including Hyderabad coordinates, elevation in feet, and summer dry and wet bulb temperatures.

Add weather data as per hap data source using the hap software by selecting a city, which auto populates latitude, longitude, and elevation from the 2001 Ashrae Handbook.

Create schedules in hap software via project libraries, using working day and holiday profiles. Duplicate templates for lighting, equipment, and fans, and assign sensible and latent heat across the week.

Design wall layers by selecting an outside wall, assigning absorptivity for dark colors, and calculating inside and outside surface resistances from ASHRAE to determine R and U values.

Create a new default roof and name the roof assembly, select a dark exterior color, define inside and outside surface resistances, and add cement plaster with eight-inch concrete layers.

Open project libraries, choose windows, and create window entries with names and dimensions, then record exposure directions, u values, and shading coefficients, treating curtain walls as windows when calculating area.

Add data for doors by opening door properties, entering a 35 ft² main door with wood U-value, and detailing a 9 ft² glass area with SHGC 0.64.

Learn how to add data for shades by configuring shading geometry properties such as reveal depth, overhang, height above window, extension past left and right, and fin projections.

Master internal load details for spaces, including overhead lighting types, recessed vented versus unvented, return air interactions with light ballast, and Ashrae data such as 1.4W/ft².

Enter wall exposure areas for classroom one using schedule, detailing north west and south west walls, and assign window quantities and directions; the door is not an exposure door.

Learn how to define roof types and areas in a project, including flat and horizontal roofs, slope details and exposure direction, and create skylight schedules with window specifications.

Calculate infiltration CFM for classroom windows by multiplying total crack length by the leakage rate, then use the window perimeters to estimate ACH in Hep software.

Identify floor type, input area and u-value, calculate exposed perimeter, and set heat flow and conditioned or unconditioned spaces for Bangalore design conditions.

Add partition details for classrooms, lobby, and offices by selecting partition walls, defining exposure directions, wall areas, and window or door placements using space sheet and Ashrae data.

Fill information in air system properties by naming the system, selecting equipment type and air system type (such as VAV), and defining the number of zones tied to VAV boxes.

Explore hvac system components, selecting a forward curved fan with draw through configuration, while balancing low velocity duct design, duct heat gain, and leakage targets for commercial spaces.

Assign four spaces as zones—classroom one, classroom two, lobby, office—and attach vav boxes, select the thermostat schedule from the project library, and set terminal types minimum airflow cfm per person.

Set sizing data for hvac systems, choosing manual or computer generated data, and apply safety factors: cooling sensible 10–20%, cooling latent 10–30%, heating 10–20%, with a 10°F chilled water delta.

Learn to generate the system input report in HAP, review project, building, zone, and equipment data, and validate input before running the simulation for accurate HVAC design.
