"SO EASY YOUR DOG CAN DO IT"

     

This load calculation software has been developed using sound engineering principles as prescribed by ACCA's Manual J and ASHRAE's "Handbook Book of Fundamentals". 

NO OTHER HVAC LOAD CALCULATION PROGRAM OFFERS AS MANY FEATURES AT SUCH A GREAT PRICE

Plus real live help (although you probably won't need it)

 

 

Once your purchase is verified by our associate, ClickBank, you will be able to download, own and have unlimited access to your load calculation program. Our HELP menu gives step-by-step instructions, with illustrations, for performing a load calculation.

 

 

2009 International Residential Building Code

Load calculation and equipment selection required

Section M1401

Heating and cooling equipment shall be sized in accordance with ACCA Manual S based on building loads calculated in accordance with ACCA Manual J or other approved heating and cooling methodologies.

 

 

2009 International Residential Building Code

Duct design required

Section M1601

Duct systems serving heating, cooling and ventilation equipment shall be fabricated in accordance with the provisions of this section and ACCA manual D or other approved methods.

AS EASY AS 1,2,3

It only takes the first three steps to perform a block (whole house) load

STEP 1

ENTER GENERAL INFORMATION

 

 

 

STEP 2

SELECT THE GLASS AND DUCT CHARACTERISTICS

Click the dropdown arrows to select type of glass and HTM's are automatically entered

STEP 3

ENTER BUILDING COMPONENT INFORMATION

Click the dropdown arrows to select the insulation values of the various building components and U-Values are automatically entered

THE CALCULATION FOR SIZING EQUIPMENT (block load) HAS BEEN COMPLETED!

Our illustration indicates 26,388 btuh needed for heating and 23,122 btuh (2 tons) needed for cooling

THE ADDITIONAL TABS BELOW ALLOW YOU TO :

  • PERFORM A LOAD CALCULATION FOR A BASEMENT (not illustrated)

  • PRODUCE COST ANALYSIS

  • CALCULATE ROOM-BY-ROOM LOADS AND CFM REQUIREMENTS

  • SIZE THE DUCTWORK

  • CALCULATE WINDOW HTM'S USING MANUFACTURER'S SPECS (if required)

  • Select the proper size equipment according to Manual S

BOILER NOTE: use the room BTUH load to size the convectors

COST ANALYSIS TAB

(use this tab as a sales tool)

Below is an example of comparing an existing 10 SEER A/C unit with an 80% AFUE propane furnace vs a new 15 SEER / 8.5 HSPF heat pump (use the built in map to obtain degree day information for your area). Our sample cost analysis indicates the 15 SEER heat pump will save $839 per year, the system will cost $7600, and delivers a 7.3 year payback or 13.7% return on the investment for the new equipment.

ROOM-BY ROOM TAB

Calculates individual room loads and CFM

(Calculates 16 rooms, use CFM to size duct system)

 

 

 

AIR DUCT SIZING TAB

This tab will calculate the friction rate, size the supply and return trunks and size the individual outlet runs all according to Manual D (Sizes both metal and flexible duct)

Includes square to round calculator

 

 

Window HTM TAB

This tab may be used to calculate the actual glass HTM if the manufacturer's specs must be used. Otherwise, use the built-in generic HTM's

 NEW Equipment Selection as per Manual S

These two tabs size the equipment and select the blower cfm for best temperature and humidity control, adjust the capacities for altitude, determine the available static pressure for the duct system and determine the amount of auxiliary heat needed if a heat pump is used.
