Essential Design Programs
with Accurate Sizing Calculations
help to “Streamline Your Design”
HVAC DESIGN SOLUTIONS
ENGINEERING SOFTWARE

2.  “Airside Design” from HVAC Design
Solutions is a package of software programs for
many of the HVAC Designer’s sizing tasks:
 Duct System Sizing -“Enhanced” Equal Friction
 Duct System Sizing -“Simplified” Static Regain
 Supply Fan Static Pressure Calcs
 Return/Exhaust Fan Static Pressure Calcs
 Duct Fitting Coefficients - Built-in
 Coil Psychrometrics, Preliminary Acoustics
 Extensive Help Files, and “Extras”
© Copyright 2008 HVAC Design Solutions 2

3.  Reduce your dependence on Reference Books,
Charts, Graphs, and “Rules of Thumb”.
 Eliminate many of the usual HVAC Design
Tasks
 Reduce common errors and mistakes
 Create an easy-to-follow, step-by-step
“Procedure for Airside Design” for all
projects.

A Preliminary Review of Plans and Specifications
1 Quickly review all Drawings in the Construction Document set, including Architectural,
Structural, Civil, Landscaping, Mechanical, Plumbing, Fire Protection, Electrical, Food
Service, and any other discipline. Spend not more than one minute per sheet, average.
2 Make a list of any apparent discrepancies or questions while reviewing the set, and add
‘flags’ to sheets where there are significant questions.
3 Quickly review the Specifications by reading through the Table of Contents for
Mechanical and Plumbing work. Check the Table of Contents against the actual
Specification sections to verify all sections have been included. Make a list of questions
that may come up during the cursory review.
4 Review Architectural Title Sheet, or first sheet in the set, and make a list of the Project
Square Footage, Building Occupancy Type, Building Construction Type, Governing
Codes, Index of Drawings, and any other information that relates to Mechanical or
Plumbing work.
5 Check for consistent appearance of Title Blocks, Drawing Scales, North Arrows,
Professional Stamps, Company Logos, Sheet Numbers, Sheet Titles, Issue Dates, and
Issue Revisions on all sheets.
B Demolition Plans
1 Verify that Demolition Symbols (cross-hatching, etc.) are clear and complete, and are
coordinated with other disciplines.
2 Verify there are notes regarding potential hazardous materials (asbestos, lead paint,
etc.), and coordinate with Architect or other Prime Consultant and Owner.

A Mechanical Piping Plans Return to Table of Contents
1 Sum all Chilled Water Supply and Return quantities (GPM’s) from coils back to service
connection or pumps. Pencil in quantities adjacent to pipes. Verify flow rates are listed
for all coils or equipment, and that Schedules for each device are complete. Check flow
direction Arrows for completeness and correct direction.
2 Sum all Heating Water Supply and Return quantities (GPM’s) same as Chilled Water.
Pencil in quantities. Verify Schedule information is complete. Check flow direction
Arrows.
3 Check for provisions for Water Balancing on plans or on details of coil connections.
4 Check for Isolation Valves to allow servicing without shutting down and draining entire
systems.
5 Verify whether Direct-return or Reverse-return piping. Suggest Reverse-return for better
water balancing, if appropriate.
6 Check provisions for Condensate Drains. Coordinate with Plumbing drawings for piping
and Approved Disposal methods.
7 Check on provisions for Air Venting and Drainage – on Coil Piping Details and plans.
8 Check Thermostat locations (if thermostats are shown on Piping Plans) and verify all
heating and cooling elements have a corresponding Thermostat or Sensor Control.
9 Spot-check pipe sizes against totalized water quantities. Use maximum of 4 ft. per 100 ft.
pipe friction, up to 5” pipe size, and maximum of 8 ft. per second Velocity for pipe 6” and
larger.
10 Check for provisions for Pipe Expansion – Pipe Loops, adequate turns (less than 50 feet
of straight pipe), or expansion devices.
11 Check for restrictions to pipe movement – against columns, against solid walls, drops or
rises to adjacent floors.
12 Verify that pipes are not run through Stairwells, Elevator Shafts, Columns, or Electrical
Rooms.
13 Compare Totalized water quantities with associated Pumps, and analyze diversity if totals
are not equal.
14 Verify that all pipes are sized.
15 Coordinate Pipe plans with Ductwork plans and identify any potential conflicts.
