The HVAC ResLoad-J app from Carmel is an ACCA-approved Manual J8 residential load calculation app for the Apple iPad. It allows engineers, contractors, and technicians to perform field-based cooling and heating load calculations on residential and small commercial buildings. Users are then able to email PDF reports to customers and local building officials. Reports produced by this app will be acceptable by all municipalities/states (including 30+ US states that have passed laws requiring contractors to submit load calcs from ACCA-approved software.)
The HVAC ResLoad-J app allows users to create unlimited projects and perform both block and room-by-room loads. The app includes weather data for 1000s of cities throughout the world and construction data for 100s of wall, floor, roof, ceiling, and window types. The user is also able to model detailed appliance, duct, infiltration, and ventilation loads.
The HVAC ResLoad-J app was specifically designed for the Apple iPad, taking advantage of the larger screen, rotating user interface, and other functionality unique to the iPad. This app is similar to our very popular HVAC Residential Load Calcs HD app for the iPad, and it includes many of the same inputs and results. However, the "J" app is ACCA-approved, and thus requires much more detailed analysis of the building.
Other features include:
1. Includes a 1000+ world-wide city weather database
2. Allows you to create and store an unlimited number of projects. You can also re-use existing projects as templates for new projects.
3. Includes data for 100s of construction types for walls, roofs, floors, doors, windows, skylights, and ceilings.
4. Allows you to specify an unlimited # of building envelope types (i.e. – doors, walls, roofs, floors, ceilings), window types, and skylight types for each building.
5. Allows you to input individual home appliance information.
6. Allows you to instantly view total heating and cooling load results as you update input data.
7. Allows you to view comprehensive cooling and heating load breakdown reports including breakdown by envelope load, window load, skylight load, infiltration load, ventilation load and inter
