62.1-2007 Comply from HVAC Design Solutions is a package of software programs for establishing compliance with the ASHRAE Standard 62.1-2007 “Ventilation Rate Procedure”.

Includes Proprietary “Auto-Optimize”© and “VAV Scheduler”© which provide significant improvements over current “ASHRAE 62.1 User’s Manual Spreadsheet” and over the ventilation calculations in current “Equipment Manufacturer’s Load Calc” software.


Portions of the included information, descriptions, procedures, and forms are excerpts from ANSI/ASHRAE Standard 62.1-2007 (© 2007 American Society of Heating, Refrigeration and Air-Conditioning Engineers, Inc. (www.ashrae.org) Used by permission.)


ANSI/ASHRAE Standard 62.1-2007 has made significant advancements in calculations and directives to help improve ventilation air delivery to the occupants.

These changes and additional calculations, especially for multiple zone systems, have made it more difficult for engineers to determine the required outdoor air quantities.

Ventilation calculations can become quite complex.

A few necessary formulas:


E v z = 1 + X s - Z d

Evz

Xs*F

b –

*Fc

)/F

a

E v = m i n i m u m ( E v z )

V b z = R p P z + R a A z

T = 3 v / V b z

V o t = V o z

V o z = V b z / E z

V o t = a l l z o n e s V o z

Z p = V o z / V p z

V o u = D a l l z o n e s R p P z +

a l l z o n e s R a A z

D = P s / a l l z o n e s P z

V o t = V o u / E v

Keeping track of all the required formulas and calculations can be difficult.

The following example of a typical multiple zone system calculation will show the Quick and Easy input for 62.1-2007 Comply, and the Ventilation Rate Procedure compliance calculations.

Optimization procedures will show the actual reduction from an original 5,423 CFM outdoor air requirement to a final “Optimized” quantity of 2,824 CFM. This can result in a significant reduction in Owner energy and operating costs, while still complying with ASHRAE 62.1-2007.

PROJECT INFO

Straightforward takeoff and input allows easy analysis of ALL zones, to assure that the correct “critical zones” are analyzed.

All procedures, formulas, charts, and tables as prescribed by the Ventilation Rate Procedure have been included and have been used to establish the “Optimized” outdoor intake flow rate requirements.

Capacity of over 100 zones per air handling unit, using Appendix A calculations.


Proprietary “Optimization” procedures to assure that the prescribed outdoor air requirements are being met while also assuring that the outdoor air quantities are not grossly excessive. Optimization can save significant energy and operating costs over the life of a facility.

Output in the form of “Compliance Documents” for submittal to appropriate code enforcement officials or building departments.


Separate calculation procedures for multiple zone systems with and without local recirculation systems, as well as single zone systems and 100% outdoor air systems.

Time averaging algorithms for occupancy, where allowed.

Extensive “Help Files” that are hyperlinked to each program, form, or table.

Available in either I-P Units or SI Units
