HVAC System Design Disclaimer

The following pages summarizes the load calculations, equipment selection, and duct design of a residence using ACCA/ASHRAE procedures (J, S, D, 62.2) and current codes (IRC, IECC). All calculations are based on information given to PE Load Calcs LLC in the form of surveys, drawings, sketches, pictures, and meetings. In certain cases, PE Load Calcs may make reasonable assumptions about design conditions and construction materials that may or may not be accurate for the building of concern. It is the responsibility of the installing HVAC contractor to verify the design conditions, construction materials, and compatibility with existing equipment before equipment purchase and installation.

All HVAC system design work provided in the following pages are based upon information provided by the particular party submitting a particular project to PE Load Calcs. PE Load Calcs has not and does not independently verify that the data provided to us is correct or complete, and any design made by PE Load Calcs are based upon the information provided by third parties. PE Load Calcs makes no claim that the information given to us is correct or complete.

PE Load Calcs utilizes the latest Wrightsoft’s Right-Suite Universal 2015 which is an ACCA Certified and ASHRAE recommended HVAC system design software. The mathematical model and design of the HVAC system, designed by PE Load Calcs, is only as accurate as the input provided. PE Load Calcs makes every attempt possible to be as detailed and accurate as possible, however, there is no reasonable means to mathematically model an HVAC system that has not been properly installed, or has had after-the-fact building modifications or HVAC system component alterations or substitutions.

If there is any construction modifications (floor plan, roofing material, window types/sizes, insulation characteristics, or any other change that will alter the load calculation results), HVAC equipment substitutions, duct sizing or layout changes, which is not noted in this report, and therefore not provided to PE Load Calcs for consideration for the HVAC system design, then PE Load Calcs may not guarantee the performance of the HVAC system design, and all design standards and procedures performed for this HVAC system design, including this report, may no longer be valid.

PE Load Calcs will not guarantee the performance of the HVAC system design if the equipment selection and/or duct design has been performed by another party. Also, PE Load Calcs will not guarantee the performance of the HVAC system design that has not been properly installed or tested to verify performance has conformed to manufacturer specifications and design criteria provided in this report. It is up to the installing HVAC contractor to properly install, test, and verify all components of the HVAC system. All installing HVAC contractors are expected to follow ACCA Standards 5 and 9 for quality HVAC equipment installation.

All information on any existing HVAC equipment (prior to design) to remain with an existing structure must be provided to PE Load Calcs prior to the design for appropriate selection of new and compatible equipment. It is up to the installing HVAC contractor to verify equipment compatibility between with the newly installed equipment (per design) and any existing equipment remaining, via manufacture specifications and airflow/static pressure measurements.

PE Load Calcs does not provide architectural or engineering plans or diagrams for the public or for use by contractors or construction companies as final “construction documents”. PE Load Calcs works with architectural and engineering firms and with contractors in connection with their designs of HVAC systems.

Copies of this report, including the completed balance report (and any other documents that need to be completed by the installing HVAC contractor verifying equipment performance meeting design requirements and manufacturer specifications), must be kept on file by the installing HVAC contractor, and also a copy given to the homeowner to remain attached to the HVAC equipment, and to any other party of specific interest (i.e., code official, county, builder/architect).

All Isolated Rooms shall have 8"x14" Transfer Grills above Doors in order to allow mixed room air flow to the Central Return.

Place edge of Floor Registers at about 9" - 10" from finished wall.

Recommended Central Thermostat location in the Dining Room, far from windows, on interior wall and 5' above floor.

Plenum should extend 12"-15" beyond last run-out.

All Metal Duct Dimensions are Inner Dimensions.

*Measured Total CFM through the Heat Exchanger: **Measured ESP:

* The Technician should follow all Manufacturer’s installation instructions, local codes, as well as follow the guidelines from ACCAStandards 5 & 9. Before measuring any airflow, a thorough inspection of the duct system must be completed which includes:

1. Visual inspection to see that all ducts have been connected, sealed and are sized and laid out correctly per design report, allbranch dampers and supply terminals are installed and in the fully open position, and a new clean air filter has been installed.

2. A duct leakage test (via duct blower) that meets the more stringent of the of either the (a) 2012 IECC leakage requirements,(b) ACCA Standard 5 requirements, or (c) local code.

**If the measured total CFM through the heat exchanger is less than 85% of the design, or the ESP greater than 25% of design, at the selected design speed. Stop and go back and repeat the duct system inspection. Remember, all dampers & supply grilles should be fully open, and air filter and coils and fan should all be clean. If the problem still cannot be determined, then increase to the next blower speed setting and repeat the heat exchanger airflow measurement. Please note that it is desirable to have a 10-15% excess CFM measurement through the heat exchanger for this allows a margin for balancing the supplies since damper adjustments from the fully-open position will increase the resistance (ESP) thereby reducing the total heat exchanger airflow.

SUPPLY BRANCHES

Per ACCA Standard 5, individual room CFM are to be within ± 10%, or 25 CFM, whichever is greater, of its target CFM for the supply and return ducts. For existing construction, and existing ductwork without contractor modification, terminal CFM balancing is not required, unless otherwise specified by local code.

Room / Duct Terminal Location Target Airflow Test 1/ Final Test 2 / Final Test 3 / Final % Target

Total Airflow: Final Total: % Target Total:

Where % Target = 1 – 100 X ( Final CFM / Target CFM )

*** The Target Airflow may not necessarily be the design airflow from the design report, which was used solely for the purpose of sizing the duct design. The Target Airflow may be the averaged, or normalized average, of the design heating and cooling airflow values.
