CHVAC
The Elite Software CHVAC program
quickly and accurately calculates the
maximum heating and cooling loads for
commercial buildings. CHVAC allows an
unlimited number of zones which can
be grouped into as many as 100 air
handling systems. CHVAC automatically
looks up all cooling load and correction
factors necessary for computing loads.
In addition, the programs can look up outdoor design weather data for over 300 cities located
around the world. There is also provision for editing the weather data as well as adding data
for other cities. Comprehensive reports list the general project data, detailed zone loads, air
handler summary loads, outside air loads, total building loads, building envelope analysis,
tonnage requirements, CFM air quantities, chilled water flow rates (if applicable), and com-
plete psychrometric data with entering and leaving coil conditions. Other outstanding features
include ASHRAE Standard 62 analysis, automatic building rotation, 360 degree wall orienta-
tions, tilted glass, exterior shading, internal operating load profiles, variable indoor design
temperatures, people diversity, pretreated outside air, seasonal infiltration and ventilation rates,
reheat loads, duct gains and losses, and return air plenums. CHVAC project data files can also
be used by Elite Software’s EZDOE energy analysis program. A Dos version of CHVAC exists,
but it is slightly less capable.
Program Output
The CHVAC program provides eleven types of reports which can be selectively previewed on
screen or printed as desired. CHVAC supports all printers that work with Windows and numer-
ous full color reports are available. The reports are: General Project Data, Air Handler Input
Data, Zone Input Data, Detailed Project Zone Loads, Air System Zone Summary, Total Building,
Air System, and Zone Load Profiles, Air System Total Load Summary, Air System Psychrometric
Analysis, Overall Building Envelope Report, Pie Charts, Bar Graphs, and the Total Building
Load Summary. Air system summary data can be exported to your favorite spread sheet. See
the sample reports below.
Program Input
CHVAC is a true Windows program that uses all the latest data entry techniques such as
toolbars, hyper linked help, and form tabs. All input data is checked at the time of entry so
that no improper data can be entered. Five types of data are requested: general project data,
outdoor design data, building material data, air handler data, and specific zone data. The
general project data includes the project and client name, designer, building opening and
closing hours, internal operating load schedules, and any desired safety factors. The outdoor

design data includes the summer and winter outdoor design conditions (automatically looked
up for you if a city reference is given) and the desired ventilation and infiltration rates. The
building material data includes the definition of master building material types for roofs, walls,
partitions, glass sections, and exterior shading. A user defined material library is available for
saving the data on common material types. The air handler data includes the fan and terminal
type, the desired heating and cooling supply air temperatures and data for duct heat gains and
losses. The zone data includes the zone name, floor length and width, number of people,
equipment watts, lighting watts, external shading data, and specific roof, wall, partition, floor,
and glass data.
CHVAC/QHVAC Differences
Although CHVAC is easy to use, it is primarily intended for consulting engineers and large
contractors who preform very sophisticated and detailed HVAC load calculations. On the other
hand, QHVAC is a low cost commericial loads program primarily intended for architectesand
contractors who design small to medium sized commericial buildings. Both CHVAC and
QHVAC follow the ASHRAE calculation procedures, but QHVAC does not have all the many
options that CHVAC has, and thus it is somewhat faster and simpler to use. Some of the main
differences are: 1) QHVAC only allows 50 zones grouped under ten air handling systems,
2) QHVAC does not allow for exterior shading and tilted glass, 3) QHVAC only accepts wall
orientations on the eight compass directions, 4) QHVAC does not allow variable indoor design
temperatures, 5) QHVAC does not allow pretreated outside air, and 6) QHVAC has no provision
for internal load profiles on lights, people, and equipment. To decide whether QHVAC or
CHVAC is more appropriate for your needs, carefully conside the features of each. If QHVAC is
missing just one of the featueres you need or soon will need, you should use CHVAC as it is
almost as easy to use as QHVAC.
CHVAC Features
• Calculates Peak Heating & Cooling Loads
• Computes CFM Air Quantities With Psychrometrics
• Calculates Runout and Main Trunk Duct Sizes
• Automates Compliance with ASHRAE Standard 62

• Links with both AUDIT and EZDOE Energy Programs

System Requirements
CHVAC requires a computer system with at least 16 meg of memory and Windows 95 or
Windows NT.
Calculation Method
Both CHVAC and QHVAC perform calculations using the CLTD procedures described in the
ASHRAE Handbook of Fundamentals. The programs use exact CLTD and MSHGF table values
where possible, otherwise direct calculations are made. This calculation technique allows the
programs to calculate for any building orientation and still produce output results that can be
easily verified by hand.

Links to Other Programs
CHVAC not only calculates peak heating and cooling loads, it also aids in selecting hvac equip-
ment and analyzing building operating costs. Project data from CHVAC can be exported to both
Elite Software’s AUDIT and EZDOE programs. Export to AUDIT when you want to analyze
residential and light commercial projects, essentially any application which uses unitary hvac
equipment. Export to EZDOE when you want to analyze large commercial projects that require
precise modeling of variable loads, equipment, operating schedules, and control schemes. For
just selecting unitary hvac equipment, use the built-in feature of reading equipment perfor-
mance databases published by the American Refrigeration Institute (ARI) and the Gas
Appliance Manufacturers Association (GAMA). If you want to create a custom sales proposal,
use the special export feature to Microsoft Office 97/Word. This allows you to take the built-in
sales proposal and further customize it.

Elite Software
RHVAC
The Elite Software RHVAC Program
quickly and accurately calculates peak
heating and cooling loads for residen-
tial and small commercial buildings in
accordance with the seventh edition of
the ACCA Manual J. This Windows
based program is visually intuitive and
exceptionally easy to use. The Heat
Transfer Multipliers (HTM values) for
all the walls, windows, doors, and
roofs listed in Manual J are stored on
disk and automatically looked up by the program as needed. Although HTM values are taken
from Manual J directly, the user does have the option of entering his own U-Value for each
wall, roof, or glass section so that a modified HTM value is used. Design weather data for over
300 cities is built-in to the program. In addition, the user can revise the existing weather data
and add additional weather data as desired. Zoning cfm adjustments are automatically handled
by the program as needed.
RHVAC also calculates the size of the runout ducts and the main trunk duct. Equipment can be
selected from the ARI and GAMA databases and printed in the reports. Comprehensive reports
list the general project data, equipment information, total building load summary, detailed
room load calculations, and a room load summary for each zone and system complete with
heating and cooling cfm values. Color graphic bar graphs and pie charts can be printed as well.
Other outstanding features include exterior glass shading, ventilation air, miscellaneous latent
loads, default room data, automatic rotation of the entire building, and the ability to share data
with Elite Software’s AUDIT operating cost analysis program. The Dos version of RHVAC
provides similar features as the Windows version, but it is less capable so please call for details
on the differences.
Full Windows Capability
RHVAC is a true Windows program and offers exceptional productivity gains as it is visually
intuitive, permits simultaneous operation of multiple programs and allows the easy exchange
of data between programs. The program lets you take full advantage of Windows capabilities
like cut and paste editing, high resolution graphics display and exceptionally complete help
resources. The program’s help features greatly facilitate learning program operation. RHVAC’s
Windows features allow it to produce a full array of easy to understand graphic reports in vivid
color. The program supports most black and white and color printers.
Program Output
The RHVAC program provides numerous presentation quality reports including a title page,
general project data, total building and system load summaries, room summary data grouped

AUDIT
The Elite Software AUDIT Program
calculates monthly and annual heating
and cooling costs for residential and
light commercial buildings. Virtually
any type of cooling and heating system
can be simulated by AUDIT including
standard DX, evaporative, air source
heat pumps, water source heat pumps,
York Triathlon, and all types of fossil
fueled furnaces and boilers. An optional version of AUDIT with appliance capabilities can
calculate appliance and hot water energy use as well.
AUDIT uses heating degree days, weather bin data, and full load cooling hours in its calcula-
tions. Weather data for over 300 cities throughout the world is built-in to AUDIT and additional
weather data can be easily added.
Along with calculating energy costs, AUDIT also performs an economic analysis that allows
you to compare system types and costs over any given study period. There is even a loan and
lease analysis report designed to demonstrate affordability of better systems by showing that
the effective net monthly cost is often very low when monthly energy savings are considered.
To make system comparisons easy, AUDIT allows you to manually enter equipment data or
automatically look it up for you from ARI and GAMA equipment data files. AUDIT provides a
wide selection of nicely formatted color charts, graphs, and reports. The DOS version of AUDIT
provides the same basic features as the Windows version, but it is less capable and you should
call Elite Software for details on the differences.
System Requirements
AUDIT requires an IBM PC compatible computer equipped with at least 8 megabytes of
Program Output
The AUDIT program provides numerous color presentation quality reports including a title
page, project summary, system comparisons, appliance analysis, hot water heating, invest-
ment, loan, and lease analysis, line graphs, pie charts, and bar graphs. The reports can be
previewed on screen or printed on any model printer supported by Windows. Any combination
of detailed and summary reports can be selected for printing by the user. All reports reflect the
input data that caused the calculated results. Shown below are just a few of the many reports
and graphs that can be printed.

AUDIT Features
• Calculates Monthly & Annual Heating & Cooling Costs
• True Windows Program! (Dos Version also Available)
• Simulates Nearly all Types of HVAC Systems
• Optionally Analyzes Appliances and Hot Water Costs
• Handles Both Simple and Complex Utility Rate Structures
• References ARI and GAMA Equipment Files
• Provides Comprehensive and Concise Graphical Reports
• Prints Color Pie Charts, Bar and Line Graphs
• Performs Economic Comparison of HVAC Systems
• Provides Loan and Lease Analysis for Purchasing Systems
• Great Sales Tool for Selling HVAC Systems
Equipment Selection
Although you can manually enter system information on equipment from any manufacturer,
AUDIT also allows you to quickly select model numbers from both the ARI and GAMA equip-
ment databases. By selecting a model number, all the information for the model is looked up
and read into the program. AUDIT can look up equipment data for all the manufacturers (over
70) whose products are listed in the Air Conditioning and Refrigeration Institute (ARI) direc-
tory and the Gas Appliance Manufacturers Association (GAMA) directory. The ARI and GAMA
database disks are $50 each and may be obtained from Elite Software.
Full Windows Capability
AUDIT is a true Windows program and offers exceptional productivity gains as it is visually
intuitive, permits simultaneous operation of multiple programs and allows the easy exchange
of data between programs. The program lets you take full advantage of Windows capabilities
like cut and paste editing, high resolution graphics display and exceptionally complete help
resources. The program’s help features greatly facilitate learning program operation. AUDIT’s
Windows features allow it to produce a full array of easy to understand graphic reports in vivid
color. The program supports most black and white and color printers.
Program Input
The AUDIT Program is a true Windows program and as such it operates in standard Windows
fashion complete with toolbars and hyper linked help. All input data is checked at the time of
entry so that no improper data can be entered. Two types of data are requested: general project
data and specific HVAC system data. The general project data includes the summer and winter
design conditions, total cooling hours, the project name and location, client information, fuel
cost data, optional appliance data, and the design heating and cooling loads. The HVAC system
data includes specific information on the system type, model number, efficiency, cost, capacity,
and fuel used. Up to six HVAC systems may be defined per project and each system can have a
backup heating system specified as well. Economic data concerning initial system cost, interest
and inflation rates, and loan amounts can also be entered. In order to minimize redundant
input, AUDIT can also import data from project data files created by the Elite Software RHVAC
program that performs Manual J HVAC load calculations.

GASVENT
The Elite Software GASVENT 2.0 program
quickly calculates the correct vent sizes for
Category 1 Gas Fired Appliances. GASVENT
is a true Windows program designed to be
simple and easy to use by both contractors
and designers. The program is very graphi-
cal and especially easy to use.
Recent advances in technology have
improved the average furnace efficiency to over 80%. These new mid and high efficiency fur-
naces can cause significant condensation in the vent. If a flue gas vent is either oversized,
undersized, or of the wrong material, there is a high probability that corrosive condensate will
cause pitting which will ultimately result in the failure of the vent pipe. The failure of a vent
pipe can be deadly because the building occupants could be subjected to carbon monoxide
poisoning. Besides gas poisoning, there are many other hazards from improperly designed vents.
Masonry chimneys can collapse from the acid in the condensate dissolving the mortar between
bricks and possibly causing a fire. Condensate can accumulate back at the furnace and cause
severe rusting. There are so many potential problems with incorrect venting, that all contractors
should make every effort to do the job right. GASVENT is a great help in vent design.
Full Windows Capabilities
GASVENT is a true Windows program and offers exceptional productivity gains as it is visually
intuitive, permits simultaneous operation of multiple programs and allows the easy exchange of
data between programs. The program lets you take full advantage of Windows capabilities like
cut and paste editing, high resolution graphics display and exceptionally complete help re-
sources. The program’s help features greatly facilitate learning program operation. GASVENT’s
Windows features allow it to produce a full array of easy to understand reports.
GASVENT Update
Current users of Windows GASVENT 1.50 may update to GASVENT 2.0 for only $49. The pri-
mary differences between GASVENT versions 1.5 and 2.0 concern new calculation routines,
better handled multi-floor and multi-appliance applications, easier entry of manifolds, updated
graphics, and new visually appealing reports. Updated graphics, a new manual, and a new help
file make GASVENT 2.0 for Windows the easiest to use gas venting program on the market. Stay
in compliance with the National Fuel Gas Code the easy way, with GASVENT for Windows!

GASVENT Features
• Calculates Vent Sizes for Category 1 Gas Fired Appliances
• True Windows Program!
• Follows National Fuel Gas Code and GAMA Procedures
• Sizes Single and Double Wall Metal Vents
• Computes Combustion Air Requirements
• Calculates Acceptable Tile Lined Masonry Chimney Sizes
• Sizes Type B and Single Wall Metal Vent Connectors
• Calculates for Single and Multiple Appliances
• Works for Both Single and Multi Story Buildings
• Allows for Drafthood and Fan Equipped Appliances
• Accommodates any Height and Lateral Dimensions
• Graphical, Context Sensitive Help
• Hypertext Feature Provides Link Between All Help Items
Calculation Method
GASVENT calculates vent sizes based on the vent tables developed by the Gas Research Insti-
tute and subsequently published in the 1996 National Fuel Gas Code by NFPA and the 1991
manual entitled, Venting Tables - Category 1 Central Furnaces, published by the Gas Appliance
Manufacturers Association. All output results produced by GASVENT can be easily verified by
hand to conform with results from the vent tables.
Program Input
The GASVENT program uses standard Windows data entry techniques that provide a full
screen, simple "fill in the blank" input procedure. All input data is checked at the time of entry
so that no improper data can be entered. If you have a question about what the program is
requesting, you can press the F1 key for context sensitive help.
Additionally, there is a Hypertext feature that links all help information together. Three major
types of data are requested: Customer Information, Single Appliance, and Multiple Appliances.
The customer information includes the customer name, address, city, state, and phone number.
A single appliance requires the appliance description (furnace, water heater, etc.), input MBH
rating, vent lateral and height dimensions, outlet diameter, vent connector type, specification of
natural or fan assisted draft, vent type (masonry, flexible liner, or Type B), and the number of
elbows.
The same data is requested for each appliance in multiple appliance situations. Multiple appli-
ance scenarios also allow the entry of a "floor" number for multi story buildings. All data is
saved to disk and can be reviewed and edited whenever desired. Input sheets are provided for
the easy organization of your data.

Program Output
Output results from GASVENT are shown on each input data screen and can be printed when-
ever desired. Reports can be both previewed on screen or printed. Both Draft and Proof quality
reports can be printed. Shown below are sample reports and screens from GASVENT program.

HVAC Tools
The Elite Software HVAC Tools program
allows the quick calculation of 13
common HVAC design tasks. These
tasks include duct sizing, wire sizing,
three way coil interpolation, mixed air
and state point psychrometrics, fan
curve and cost analysis, U-Factor calcu-
lations, natural gas pipe sizing, refrigera-
tion line sizing, general pipe sizing, hot/
chilled water pipe analysis and the quick look-up of common HVAC formulas and conversion
factors. HVAC Tools is designed to be used as a quick utility for calculating these common
tasks. Minimal input is required for each function and results are instantly displayed on the
same screen as the input data. Some of the functions in HVAC Tools are also covered by other
Elite programs. For example, duct sizing is done on a system wide basis for multiple duct
sections at a time in DUCTSIZE. The Tools program just sizes one duct at a time in order to
minimize the data entry required. The same situation exists with psychrometrics, pipe sizing,
and wire sizing. Elite has other programs you may want to consider that address those
applications on a complete system basis. HVAC Tools is a simple and easy to use Windows
programs designed for both engineers and contractors. A lower priced DOS version of Tools
is also still available.
System Requirements
HVAC Tools requires a computer equipped with at least 8 meg of memory and Microsoft Win-
dows 3.1 or higher.
Calculation Method
All HVAC related items in the HVAC Tools program follow the methodology described in the
1997 ASHRAE Handbook of Fundamentals. The wire sizing procedures are based on the 1997
National Electric Code. All results computed by the HVAC Tools program can be easily verified
by hand.
Program Output
Output information from HVAC Tools can be seen on each input data screen and printed
whenever desired. There is also provision for printing a cover sheet for the output report of any
function of HVAC Tools. Shown below are sample input screens with output data for several
functions.

HVAC Tools Features
• Automates 13 Common HVAC Design Tasks
• True Windows Program! (Dos Version Available)
• Follows ASHRAE and NEC Procedures
• Sizes Round and Rectangular Duct Sections
• Sizes Wire Based on Ampacity and % Voltage Drop
• Sizes Pipes and Refrigerant Lines
• Performs Fan Curve and Cost Analysis
• Performs Mixed Air and State Point Psychrometrics
• Performs Three Way Interpolation of HVAC Units
• Automatic U-Factor Calculations for Roofs, Walls, etc.
• Hot and Chilled Water Pipe Sizing and Analysis
• High and Low Pressure Natural Gas Pipe Sizing
• Quick Look-Up of Common HVAC Formulas
• Provides Comprehensive and Concise Reports
Program Input
The HVAC Tools program is a true Windows program and as such it operates in standard
Windows fashion complete with toolbars and hyperlinked help All input data is checked at the
time of entry so that no improper data can be entered. Each function of Tools requires only one
screen of input data. Most functions require only a few items of input data. Others, like the
HVAC Formula look-up, require almost no input data.
The Duct Size function, for example, requires the length of the duct, the cfm of air carried by
the duct, the desired pressure loss per 100 feet of duct, and the material of the duct. There is
also provision for entering height and width constraints along with minimum and maximum
velocity constraints. The Refrigeration Line Sizing function requires refrigerant type, tonnage,
temperatures, pipe lengths and type.
The Psychrometric function requires only two conditions to determine all other properties of
air for a given state. The Fan Curve Analysis only requires any two of the following inputs: fan
rpm, cfm, static pressure, or brake horsepower. The Wire Sizing function requires the load in
either amps, horsepower, or kva. Given the voltage, wire length, material (aluminum or cop-
per) and conduit type, Tools sizes the smallest wire that does not exceed NEC ampacity ratings
or the user specified allowable % voltage drop.

Drawing Board
DRAWING BOARD is a fast and simple program for
drawing floor plans and ductwork. Drawings can be
quickly created by dragging and dropping drawing
objects from the built-in object catalogs onto the
drawing window. The drawing objects in Drawing
Board are pre-programmed shapes such as entire
room shapes, walls, doors, windows, and ductwork.
These are intelligent objects that contain data useful
for the CHVAC, RHVAC, and Ductsize programs. Soon, several other Elite Software programs will also
include a Drawing Board window, each one having its own new, custom catalog of intelligent objects.
Drawing Board costs only $495 and it can run as either a stand-alone program or as an integrated
component within other Elite Software programs such as RHVAC, CHVAC, and DUCTSIZE. If you
buy Drawing Board, it automatically becomes enabled inside of all programs you have from Elite
that relate to Drawing Board. For example, if you own both RHVAC and Drawing Board, you can
sketch the floor plan of a project on the drawing window of RHVAC and calculations will
automatically be performed right from the floor plan you create. You can also draw the ductwork
for the project on the Drawing Board window in RHVAC, which you can either size manually
from within RHVAC, or you can open the same drawing in DUCTSIZE and let that program
calculate all the duct sizes for you automatically.
A demonstration version of Drawing Board is included with each program that includes the
Drawing Board window. As an example of the demonstration limits of the Drawing Board
window, in RHVAC you can draw as large a floor plan as you like, but the load calculations will
only be done for the first three rooms you draw, and the rooms will be limited to certain
dimension restrictions. Once you purchase a license for Drawing Board, the drawing window will
be ‘unlocked’ and load calculations can be done for all the rooms you draw on a drawing, no
matter how large the rooms are.
DRAWING BOARD ADVANCED FEATURES
Professional Appearance: Drawing Board uses full color, detailed, double line shapes for walls,
windows, doors, and ductwork. This gives the drawing a much more professional appearance than
simplistic single line representations.
Realistic Ductwork: Drawing Board shows ductwork completely realistic with bends, curves, and
fittings just like you have to install it. Duct board and sheet metal shows as solid grey or any color

you like. Flex duct even looks like flex duct. Each duct section is shown on the drawing with its
size and cfm, perfect for giving to the installer. Return duct sections appear just as nice and can be
given a different color from the supply duct. Far superior to simplistic right angle stick drawings
used for ductwork in other drawing systems.
Realistic Duct Fittings: Drawing Board can show realistic double line duct fittings that can be given
any color. These fittings accurately depict what will actually be installed and make for specification
quality drawings.
Register/Diffuser Options: Drawing Board offers both round, oval, and rectangular registers that
can be specified to any size, shape, and color you like. Flow arrows can also be specified to
indicate one way, two way, three way, and four way operation.
Full Precision: Drawing Board allows very precise control of line lengths and areas. No need to
worry about rounding errors and unwanted shifting of objects due to lack of precision. You can
set the grid and “snap to” setting to any precision desired.
Undo: If you make a mistake while drawing, click Undo to backtrack your changes. The Undo
dialog shows you a preview that helps you to choose precisely how many of your changes to
undo. You can undo a single change or go as far back in the current drawing session as you like.
Dimensions: Drawing Board provides accurate, easy-to-place dimension lines for all aspects of the
drawing. All types of English and metric units are provided.
Room Shapes: Drawing Board allows rooms with any number of walls and odd angles desired.
The basic rectangular room shape can be modified as desired or select from eleven standard room
shapes to save even more time.
Individual Walls: All walls drawn with Drawing Board are individually selectable. Each wall can
have its own material type, R value, orientation, and other properties related to HVAC load
calculations. This also makes it very easy to define a partition wall separate from an exterior wall.
Door Options: Doors can be drawn with any degree of opening and swing arc desired. Hinge side
and swing direction are easily selectable and changeable.
Floors and Layers: Drawing Board allows multiple story floor plans by using the concept of a sheet
to represent each floor and layers to contain different types of objects per floor.
Rooms, Zones, and Systems Colors: Rooms can be assigned to zones and zones can be assigned
to air handler systems that make up the building. Drawing Board allows room and zone areas to

have different background colors so that it is easy to distinguish them.
Zoom and Pan: Drawing Board provides numerous dynamic zooming and panning tools.
Scaling: Drawing Board allows setting the size of the drawing page and includes all the standard
architectural sheet sizes and scales, thus providing an accurate “WYSIWYG” picture of what the
drawing will look like while you are still working in the editing mode.
Printer Options: Drawing Board can print a floor plan on regular 8.5 x 11 paper or any size paper
your printer or plotter will allow.
Large Drawings: Drawing Board can also print a large drawing over multiple sheets of paper when
the drawing is larger than the printer’s standard paper size.
Appearance Control: Drawing Board gives custom control over the appearance of all drawing
objects and layers. You can change settings like the line type, color, and shadow if desired. All text
can be specified with any font style and point size desired.
North Arrow: Drawing Board provides an intelligent “north arrow” object that can be set to any
direction desired and which controls the orientation assigned to all walls and windows.
Borders, Title Blocks and Notes: Drawing Board makes it easy to create custom borders, title
blocks, revision clouds, and callout notes.
Standard Shapes: Drawing Board offers lots of standard drawing shapes including polygons,
polylines, lines, rectangles, ellipses, arcs, text, rounded rectangles, and pie and chord objects. Use
these to outline patios, flowerbeds, sidewalks and even create objects for custom object catalogs.
Customizable Toolbars: Drawing Board uses five toolbars which can be fully customized and
located wherever desired.
Calculation Links: Drawing Board works with Elite’s CHVAC, RHVAC, and DUCTSIZE programs
and soon it will link with FIRE and other Elite programs as well.
Object Catalogs: Drawing Board has a collection of drawing objects to supplement projects.
Objects include heating equipment (boilers, radiators, hydronic floor tubing, panels, etc.),
appliances (washers, dryers, refrigerators, etc.), furniture (sofas, chairs, tables, etc.), plumbing
fixtures (sinks, bathtubs, showers, etc.), electrical (outlets, switches, lights, etc.), landscaping (trees,
shrubs, flowers, etc.) and many more objects.

A basic use of Drawing Board is to create floor plans so that hvac load calculations can be
performed from the plans with RHVAC and CHVAC. Duct work can be drawn and manually sized
using RHVAC and Drawing Board, or automatically sized by using DUCTSIZE.
SYSTEM REQUIREMENTS
Our Windows software applications are compatible with all Windows Operating Systems
(Windows 95, 98, ME, NT 4.0, 2000, and XP). The minimum hardware requirements to run our
application are the same as the minimum hardware requirements to run the operating system
which the application is installed on. Additionally, 32MB of RAM and 10 MB of hard disk space is
recommended to run DRAWING BOARD.
The latest updates for RHVAC, CHVAC, and Ductsize each include a built-in Drawing Board
window that works at the demonstration level. It lets you create floor plans or duct layouts of
unlimited size, but calculations will only be done on the first few rooms, zones, or ducts you draw
(3 rooms in RHVAC, 2 zones in CHVAC and 6 trunks, 6 runouts in Ductsize). Once you purchase
a Drawing Board license, these limitations on the drawing are removed.

Drawing Board can be used for more than just drawing basic floor plans and duct systems. The
drawing below illustrates using Drawing Board to embellish a drawing complete with furniture,
appliances, landscape items, and even cars in the garage. All the objects in the drawing below
were just dragged and dropped into place. It is very easy to win more clients by offering full
architecturally correct drawings.

found in Microsoft Word. But more than just a word processor, the main advantage of Proposal
Maker is that is creates proposals automatically from equipment selection and cost comparison
results obtained from Elite’s Energy Audit and Rhvac programs and soon from Elite’s Chvac
program. As equipment is selected and compared, key results such as savings and payback

amounts are automatically pasted in both text and graphic form into the proposal. Additionally,
pictures of the equipment being proposed can be shown as well. There is also provision for
inserting your own pictures into a proposal such as a picture of the old unit that will be replaced
or a picture of who will install the unit.
Proposal Maker is very flexible in that multiple proposal formats can be maintained. Use a long
form format with lots of detail for that college professor customer or a short form for a single
working parent with little time for details. Proposal Maker comes with numerous ready to use
proposal formats, but you can create any number of new custom formats. Besides proposal letters,
Proposal Maker can also print numerous support documents such as copies of customer referral
letters, rebate forms, and credit applications, even factory literature can be printed for the
proposed products! In this way, a very persuasive packet of information can be delivered to the
customer. The proposal documents can be printed and delivered in full color or they can be
created as PDF files and e-mailed directly to the customer right from Proposal Maker. Dramatically
increase your sales with Proposal Maker!
Document Editing
If you know how to edit a document with a word processing program such as Microsoft Word,
you already know most of what you need to know to use Proposal Maker. Changing font and
paragraph settings is done with dialogs that are similar to what you are already used to with your
own word processor program.
Inserting Live Fields
Adding fields from the host program is a snap. Just find the field you want in the Field Catalog,
such as the cooling capacity of the unit you selected for system 1, then drag and drop the field
onto the document where you want it to go. The field will automatically update itself to show the
data from the current project.
Buyer’s Guide
Here are a few things to look for when shopping for a program like Proposal Maker:
• Familiar Word Processor Features - The processor itself should be very similar to the word
processor program that you already learned how to use, such as Microsoft Word. You don’t
want to have to learn a whole new way of doing things. Shortcut keys, dialogs, menus, and
buttons for changing fonts, paragraphs, tables, etc. should be similar to the ones you are
already familiar with.

• Fields for Main Calculation Results - The program should provide insertable fields that
automatically link to all the main calculation results of the host program. For example, you
should be able to easily insert fields for the sensible and latent gains, the sensible loss, the
CFM requirements, the operating costs, amount of infiltration, etc...
• Fields for Each Input - As far as is practical, the program should provide insertable fields that
link to each of the host program’s inputs, such as the client name and address, the outdoor
design conditions, and the air conditioner and furnace model numbers that were selected for
each system.
• Drag and Drop Fields - The program should let you insert fields on the document with drag
and drop, in addition to inserting at the cursor location. Drag and drop is much faster when
you want to insert several fields. You don’t want to have to keep clicking back on the
document to position the cursor each time you insert a new field.
• Multiple Documents - You should have the ability to create multiple documents in a single
project. You should be able to have things like a proposal, an envelope addressed to the
client, a thank you letter, a follow up letter, all within the same project for a particular
customer.
• Easy Template Selection - When you start a new document, the program should prompt you
with a list of available templates to choose from, and should show you a WYSIWYG preview
of each template so you will know how it really looks on the page before you start your new
document.
• Dynamic Picture Fields - The proposal program should provide dynamic picture fields, not just
the ability to insert static pictures. Picture fields are intelligent pictures that automatically
change based on the selections you made for the project. For example, the program should
give you a picture field that will show the outdoor condensing unit for the air conditioner you
selected for the current project, and if you later select a different unit the picture on the
document should change automatically.
• Live Graphs - The program should let you insert live graphs onto the document that show the
calculation results of the host program. A live graph is not just a static picture, but is an
intelligent chart that automatically updates itself on the document to reflect the new results
whenever you change anything in the project.
• Customizable Toolbars and Menus - If you have done much work in a word processor
program you know that one of the most important things is to be able to customize the

toolbar and menus so you can make the tools you use most often easier to get to, and so you
can set the shortcut keys however you want. The program should adjust to suit your
preferences, not the other way around.
• Accessible Menus - The menus for the document window should be easily accessible without
having to go through several sub-menus to get to the item you want.
• Extensive Field Properties - The program should give you the ability to change the properties
of fields that are already on the document, and should give you a full array of choices for each
field. For example, a field on the document that show fuel cost for a system should let you
change which system is referenced, which type of fuel (electricity, natural gas, etc...), and how
the number is formatted.
• Custom Formulas - The proposal program should give you the ability to put fields on the
document that use your own custom formulas that the program evaluates and shows the
results for. For example, you should be able to create your own field that takes the system list
price and automatically adds 4% sales tax. Another example would be to define a field that
automatically calculates the difference between the projected operating costs of two of your
proposed systems.
