New Video on Importing AHRI Equipment Data for Rhvac

We recently added the Elite CSV Converter feature to Rhvac, which lets you convert a data file that you download from AHRI into an Elite Software equipment database, which you can then use in Rhvac. And we created a new video that shows you how to use this powerful, new feature.

On 3/20/2024 we released a new version of this video that shows you how to delete the advertisement in row 1 of the XLSX file that AHRI added immediately after we added this new feature to Rhvac and posted the video.

2023 AHR Expo

February in Atlanta was the perfect weather for the ASHRAE show: no snow, rain or bad weather. After Chicago 2021 was canceled due to Chinese Covid, and Las Vegas 2022 was weak since many held back, Atlanta was a mild improvement. Not quite like previous Atlanta shows, but one can't forget massive inflation, airline chaos, and a weakening demand to travel and visit expos as contributing factors. For those who did attend, we enjoyed discussing current projects, and we let them peek behind the curtain on some new major revisions (soon to be announced!).

2022 AHR Expo

Having expected the Vegas show to be smaller in attendance and sales, and still very mask-restricted, we were pleasantly surprised by the volume of sales.  Not quite the Chicago show, Las Vegas was definitely worth our while.

Next year we look forward to visiting Atlanta, one of the nicest cities in the rotation.  Come on down and see us!

John Walsh

It is with great sadness that Elite Software announces that John Walsh, longtime trainer and reseller of Elite Software, passed away on May 2, 2021 at the age of 79. John was a long time and loyal friend of Elite Software and all of its customers. John would gladly take calls from software users on an essentially 24/7 basis. Customers loved John's wit and humor along with his willingness to help at all hours. Elite Software will never have another partner willing to do what John did for over 15 years.

2021 AHR Expo Cancelled

We had invited you to come see us at the 2021 AHR Expo, originally scheduled for January 2021 in Chicago, but due to the Chinese Coronavirus/Covid situation, AHR Show Management has been forced to cancel this event. There was a possibility it would be postponed to March 2021, but due to safety precautions and large/mass event restrictions, it was not going to happen.

The next scheduled trade show will be AHR Expo 2022, in Las Vegas, Nevada.  By then, we hope all will be normalized and we can safely and happily meet with you - nothing beats in-person discussions.  So give yourself a mini-vacation in 2022, see the sights of Las Vegas, and drop by our booth.  For more details, please visit:  AHR Expo 2022 (https://www.ahrexpo.com/updates).

2020 AHR Expo

Reporting news from warm Orlando:

Elite Software exhibited at the 2020 AHR Expo in Orlando early February. Attendance was outstanding - better than in the last few years. We heard one other exhibitor say, "We started working at 10 and didn't look up until they flashed the lights for closing at 6." That was our experience as well, interacting with a continuous stream of new prospects, adding quite a few new customers, and enjoying visiting with the many old friends who came by to visit and discuss future projects and designs.

Next year should be a positive year too, with the economy going so strong, and Chicago a strong showing in a centrally located city. Come see us in the Windy City, and as always, bring your suggestions along!

Rhvac Now Imports from REM/Rate or Ekotrope Programs

Rhvac can now import an XML file that was exported from the REM/Rate program or the Ekotrope program. So now in addition to being able to export an XRR file from Rhvac to import into REM/Rate, you can now import an XML file from either REM/Rate (remrate.com) or Ekotrope (ekotrope.com). So you may now start your project with either of those other two programs, and then transfer your project information into Rhvac with this new feature. Click "File | Import | Import XML File from REM/Rate or Ekotrope" to use this new feature.

2019 AHR Expo

We just returned for the AHR Expo in Atlanta, where the Superbowl buzz was in the air during the 3 day exhibit. Luckily, we missed both the expected nightmare traffic and the polar vortex cold snap. Since they started to use RFID badges, we can now know the actual show attendance, which parallels our booth experience - significantly busier this year compared to last year. Nice.

Next year, AHR Expo is in Orlando, so the weather will guaranteed be nice, and some of us plan to bring our families to piggyback a vacation at Disneyworld+Universal Studios. See you there!

Mother Nature gave us a break with mild conditions in Chicago. January could have been a deep freeze or worse, a blizzard travel disaster, but no, it was quite reasonable, and that allowed new customers and old friends to visit with us.

Also nice was our new booth design (photo below), as well as demoing our smart-looking, easy-working mobile Manual J/D/S program, Rhvac Online. We received lots of compliments for providing a portable version of our residential flagship with the same full room-by-room calc capabilities as the Windows Desktop version. No half measures here.

Rhvac Online is now in the hands of iPad, iPhone, Android users, as well as Windows users, and existing Rhvac version 9 users can exchange projects back and forth for the ultimate in usefulness. Go check it out at www.elitesoftapps.com.

2016 AHR Expo

This year's AHR Expo was in beautiful Orlando Florida, home of Walt Disney World. We saw great attendance, probably because the weather was so inviting and many visitors could bring along their families for a nice break from winter's chill.

Many a dad was there to show his kids what the future looks like, and how much technology and modern tools have made it easier to do his job.

We look forward to visiting Las Vegas next year, especially since Vegas has gotten so fun friendly too!

Price of Light Program Reduced by $100

We've just lowered the price of the Light program from $395 to $295! With the proliferation of manufacturer provided lighting software, the Light program has been operating "under the radar" lately because its advantages over the manufacturer programs aren't very well known.

One such advantage with Light is that you don't just have to do a one-off calculation for a single room with one type of luminaire, but you can do a whole project with hudreds of rooms, with each room having multiple luminaire alternatives. Light makes it easy to import and process the latest IES data files from any manufacturer, and it doesn't take long to get up to speed learning the program and starting to do production work with it. Download the functional demo here and see for yourself.

2015 AHR Expo

This year's ASHRAE show was set in Chicago, and the schedulers must have planned it perfectly, as the heavy snows happened a week before and a week after. Lucky us! So we were able to see many of our friends and customers at the show, rather than hear that many could not make it due to bad weather. Next year, ASHRAE is in Orlando, so weather won't be an issue. See you there!

- January 2014 -

2014 AHR Expo

What with all the extreme cold weather this winter, Elite staff were worried that getting to the NY ASHRAE show would be an issue. We lucked out, flying the day before the 10+ inch snowstorm and missing the mass flight cancellations. So who would have suspected that our return flight to Houston would be canceled on account of icy weather - in Houston?

What matters though, is the time we spent in NY between the flights. ASHRAE NY was busy for us in spite of the weather, so the days just flew on by from customer to customer, along with visiting with many old friends.

We look forward to next year at Chicago, though can we skip the cold, please?

Problems with Avast Antirus Software

We have had several reports of the Avast brand antivirus software causing problems with some of our programs, such as Rhvac, because it flags certain DLL files as being suspicious, and removes them from your system. These are files that we created and that have been around for over 10 years, and Avast has just in the past few weeks started erroneously flagging them. We have been letting them know about this problem since October 3, 2013, and they are still unable to correct their software.

If you use Avast antivirus and notice any problems with Elite Software programs, try turning Avast off and then reinstall the latest version of your Elite program from the Program Updates page. If the problem goes away, then that means the problem is with Avast. Trying to restore the "suspicious" DLL files from Avast's Virus Chest and adding the files to Avast's Exclusion List will not work (we've tried it), and Avast will just keep removing them from your system. So if you're having this problem the only solution we know of, until Avast corrects their software, is to uninstall Avast and consider using some other antivirus software.

2013 ACCA Conference

ACCA had its annual meeting this year in beautiful Orlando, home of Walt Disney World. Elite was pleasantly surprised to see a reenergized economy driving a strong attendee presence and interest at our booth.

We hope to see more of this next year, and, of course, hope to see your smiling faces too. See you next year!

2013 AHR Expo in Dallas, Texas

This year's ASHRAE show was based in our native Texas, in downtown Dallas. We are happy to note that for once, we were just a short drive away from home, rather than the usual airport hassles, and quite lucky to enjoy early Spring weather as well. Visitors remarked, unsurprisingly, that everyone in Texas is so friendly. Our only down note was the number of orders placed on the floor were so great that our usual quick turnaround hasn't been. Yes, what am I complaining about?

Next year's show will be in New York City, where our last experience downtown, especially near Ground Zero, was most warm and friendly. We saw the memorial under construction, and we look forward to visiting it, as well as the new tower next year. See you there!

Chvac Now Uses the Word "Room" Instead of "Zone"

The latest update of Chvac version 8 now uses the word "room" instead of "zone" when refering to the smallest space for which loads and airflows are calculated. This change was done in order to avoid confusion, since "zone" in the HVAC industry almost always means a group of spaces and not just a single space, and "room" is universally understood to mean a single space.

We've also replaced the word "group" with "zone," for the same reason. So the load calculation levels in Chvac are now: Building, Air Handler, Zone and Room.

The 2010 Florida Building Code Becomes Effective

On March 15, 2012 the 2010 Florida Building Code became effective. For Florida HVAC contractors, this is very significant because now heating and cooling load calculations in accordance with the latest ACCA Manual J procedures have to be performed to obtain a permit to install new HVAC equipment or even perform an equipment change-out. Each application for an AC change-out will need to include Manual J sizing calculations.

In section 403.6 of the Energy Conservation portion of the 2010 Florida Building Code you can read the exact wording as below.

403.6 Heating and cooling equipment (Mandatory).
403.6.1 Equipment sizing. Heating and cooling equipment shall be sized in accordance with ACCA Manual S based on the equipment loads calculated in accordance with Manual J or other approved heating and cooling calculation methodologies, based on building loads for the directional orientation of the building. The manufacturer and model number of the outdoor and indoor units (if split system) shall be submitted along with the sensible and total cooling capacities at the design conditions described in Section 302.1. This Code does not allow designer safety factors, provisions for future expansion or other factors which affect equipment sizing.

In discussions with Florida code officials, Elite Software's understanding is that only a hand calculation or software results that follow the latest ACCA Manual J 8th (MJ8) edition procedures are allowed for submittal. Software cannot simply claim to follow MJ8, it must be one of the four ACCA reviewed and certified computer programs as seen here.

Note that Elite's Rhvac program is one of the ACCA certified MJ8 programs and is suitable for submitting and obtaining HVAC permits in Florida.

Rhvac's EnergyGauge USA Link Will Soon be Updated

We will soon be releasing an update to Rhvac version 9 that links with the new version of EnergyGauge USA, version 3.0.00. We've been getting a lot of calls asking about it, so we figured we should let everyone know that the new link is coming soon!

2012 AHR Expo in Chicago, Illinois

Although the Software Center was located toward the back of one of the exhibit halls, and we were concerned about the location being weak on traffic, we were pleasantly surprised with the usual amount of traffic for a Chicago show, i.e., your first chance for a breather is a busy three hours into the day.

We really lucked out on the weather, with the show occurring during a lull in the typically frigid Chicago weather. Not only was the climate warmer than usual, but so were the many visitors to our booth. Yes, midwest hospitality is just a handshake away.

Next year the show moves to Dallas. We look forward to inviting everyone to experience Texas hospitality while we show our wares. Howdy!

Setting the Record Straight: Rhvac Was the First Manual J Load Calc Program

Did you know that Elite Software's Rhvac program was the first Manual J based software ever released? Since there is some incorrect information about this subject posted in various places on the Internet, we figured we ought to set the record straight.

In 1984 Elite Software released the very first ACCA Manual J load calculation software. It was called "RHVAC," and was based on Manual J 6th Edition. It was written in CBASIC, and worked on many small 64K memory computers under the CP/M operating system. Some of these computers included Imsai, Osbourne, KayPro, Cromemco, Vector Graphics MZ, Heath/Zenith, and Northstar. Many computers in those times did not come standard with CP/M, but were able to be upgraded with CP/M, including the Apple 2, TRS-80 Model 2, Model 3, Model 4, Model 12 and Model 16.

In March of 1986 ACCA published Manual J 7th Edition, and by June of 1986 RHVAC was updated to conform to the 7th Edition changes.

Essential New Article on HVAC Load Calculations

Elite Software president Bill Smith has just written a great new article that deals with all the residential and commercial HVAC load calculation methods available today, and explains why results are often so different between methods. If your business deals with HVAC load calculations you should consider it essential reading.

- March 2011 -

Sloped Ceiling Area Calculator added to Rhvac Version 9

Here's reason number 5,423,782 to to upgrade to Rhvac version 9: The new Sloped Ceiling Area Calculator, which calculates the area of a room's sloped ceiling (okay, it's really only reason number 10 at this point, but it is a pretty cool feature). This new dialog saves you from having to do the math to calculate the area of a sloped ceiling in a room. All you have to do is enter a few dimensions and the area is calculated for you and copied to the Room Data window. All the dimensions you enter are saved for each roof/ceiling in the project. Here's a screenshot of this new dialog.

Equipment Cooling Loads Window added to Rhvac Version 9

Here's one more in a long list of reasons to upgrade to Rhvac version 9: We've added an Equipment Cooling Loads window, which lets you enter multiple items of sensible and latent gains due to equipment for each room. You can enter as many items of equipment as you like, and apply Manual J diversity factors to each item. The dropdown help for the Item Name includes a user-editable list of equipment loads from Manual J's Table 6B, such as coffee makers, refrigerators, etc.. The Detailed Room Loads report now includes a new section showing the sensible and latent gains from each piece of equipment you entered for the room. Check out a screenshot of this new window here.

Rhvac Version 9 Released

Rhvac version 9 is now officially released, and is available for download and for purchase in our online store. The new version includes several powerful new features, such as the Tabular Manual D Ductsize window, which is our easiest-to-use duct design interface yet. This new version also exports to the advanced energy analysis program EnergyPro. Several other advanced features have been added, which are listed here.

You can download the functional demo of version 9 by clicking here. Version 9 will not interfere with version 8 at all, so if you already have version 8 you can install version 9 without any changes being made to your version 8 program or project files. Click here to see the upgrade pricing schedule and purchase the upgrade.

EnergyPro Software Now Available

We have added the advanced energy analysis program EnergyPro to the line of software titles we offer.

2011 AHR Expo in Las Vegas, Nevada

You'd think with the economy slow, especially in construction, that the show would have been slower than usual, right? Wrong! We stayed so busy, especially the first two days, that the day just flew on by, and we had to retire to a nice, quiet evening at the hotel to recharge for the next day. As always, it was pleasant to see many old friends and meet a great many new ones, even if the weather surprised us with a cold chill. We'll be ready for the cold weather and warm handshakes next year at Chicago.

Gary Lewis is Elite Software's new VP of Energy Support Training

Elite Software Development of College Station, TX has announced Gary Lewis as its new vice president of Energy Support Training. As national sales and training manager, John Walsh continues to provide general software training, while Lewis will specialize in providing training for those companies wanting to expand into the growing market of home energy surveys, ratings and audits.

There are a myriad of new certifications available, such as Home Energy Survey Professional, Home Energy Rater, Energy Star, Home Star, and BPI certified professional. These certifications involve such organizations as Building Performance Institute, RESNET, and the U.S. Department of Energy. Obtaining such certification allows an HVAC professional to provide more services in conjunction with the ones he already provides. For example, an HVAC contractor that already does the work needed to perform a load calculation can use that samework and information to create a home energy survey and get paid for doing that. With just a little bit more work, that same contractor can earn even more by providing a certified home energy-rating certificate. All of the available certifications increase the earning potential of an HVAC professional. And this is not to mention the edge they give when homeowners decide whom to use for HVAC services.

Navigating these various certifications and deciding which is best for you can be a daunting task. Moreover, obtaining certifications involves training and passing certification tests. Fortunately, Gary Lewis is an expert in this field, and is certified with all the various organizations. Lewis can advise an HVAC professional on the most appropriate certification for his goals, and the fastest and most efficient path towards achieving that certification.

Elite Software users have a special advantage towards profiting from advanced certifications. Elite Software programs such as Rhvac and Drawing Board organize the data that is needed for the various rating reports, and also link to other specialized rating software such as REM/Rate, EnergyGauge, and EnergyPro. It is much easier for an Elite Software user to create energy reports than it is for certified professionals who must start from scratch.

In conjunction with American Institute for Building Performance Standards and AHERO, Gary offers a number of training options for obtaining energy certifications and for using Elite Software programs to best advantage in performing the tasks needed to generate ratings certificates. Boosting your business with advanced certifications is easier than you think. See a training schedule here: https://www.elitesoft.com/web/training/welcome.html#greenenergysolutions and call Gary Lewis at 832-795-1003, or visit http://www.bestges.com for more information on obtaining certifications and training.


Gary Lewis has been involved with the HVAC industry for over 30 years as a sales manager and training specialist. He has worked with nearly all the major HVAC corporations such as Carrier, Trane, Lennox, and others. And this is not to mention the thousands of regular small contracting businesses that Gary has serviced and trained over the years. As mentioned previously, Gary holds numerous certifications, as shown below.

RESNET HERS - Home Energy Rater and RESNET Green Rater

2010 HVAC Comfortech in Baltimore, Maryland

It was a short but sweet trip to Baltimore, Maryland for the 2010 Comfortech trade show. Apart from visiting with many old friends and meeting new customers on the trade floor, we enjoyed the fresh sea air, the relaxed seaside ambiance and Baltimore's historical harbor. And yes, we made sure we tried every kind of crab cake we could find. If you didn't make it to this show, please join us at the next Comfortech in Indianapolis, Sept 21-23, 2011.

New Export to eQUEST From Chvac

Chvac now has an entirely new "Export eQUEST Project File" feature. The eQUEST program is a popular, free energy simulation tool that is sophisticated, yet easy to use. This new feature creates a ready-to-open eQUEST project that includes as much data as possible from Chvac, including dimensions for zones, walls, roofs, windows, skylights and doors, as well as U-factors and some other data for materials, outdoor design conditions, operating profiles, and even some of your air handler and zone data.

Our new export to eQUEST feature is a huge improvement over our previous "Export eQUEST/PowerDOE File" feature. The new feature produces a project that eQUEST can usually open without any errors, and opens as easily as projects that are created by the eQUEST program itself. Spaces are arranged as intelligently as possible, with proper orientation for spaces and correct directions for walls. Click here to download this latest update for Chvac, and click here to download the free eQUEST program.

New Online Video for Importing Floor Plans

We've just added a new video that shows how to import various kinds of floor plan files into Drawing Board. It includes information about PDF files, DXF and DWG files, and digital photo files (for when you only have a blueprint). Importing a floor plan as a background in Drawing Board saves you time. Once you have the background in place, all you have to do is draw your Rhvac or Chvac rooms on top of the rooms on the background image.

2010 ACCA Conference and Indoor Air Expo

Elite Software got to visit Tampa, Florida for the 2010 ACCA trade show, our first professional visit to the Tampa area. The weather was fantastic, the air was clean, the handshakes warm, and the smiles were big; oceanfront tradeshows just seem to bring out the best in all.

Next year ACCA meets in San Antonio, just around the corner from Elite's headquarters, and one of the up-and-coming metro areas. We look forward to you visiting the great state of Texas.

AHR Expo 2010 in Orlando, Florida

Wow. Off-year ASHRAE, well away from the traditional Chicago hub, slow economy and construction woes, and yet, wow. Let's just say that we have to apologize to our customers as the large jump in sales generated by the show will add a delay of a few days just to catch up with orders. We didn't get to go to Disneyworld, but we sure felt like we won the Superbowl!

2009 International Ground Source Heat Pump Association in Dallas, Texas

We just returned from the IGSHPA show in Grapevine, Texas (a quiet suburb of Dallas). The exhibition hall was at the Gaylord resort, a lovely place with all the amenities, and as expected, well run.

We saw more HVAC manufacturers exhibiting than last year. As to be expected with the economy, the floor traffic appeared thinner, but we were pleasantly surprised to see the caliber of attendee was better and more favorable to us, as they were agressively persuing the benefits of sizing and selling ground source systems. Due to their strong interest in our software, we look forward to them completing their research and adding them to our growing list of ground source related contractors. So this was definitely a case of "less is more."

2009 HVAC Comfortech in Nashville, Tennessee

Nashville, Tennessee was the setting for this year's Comfortech HVAC trade show. While Nashville is a decent sized city, our experience both inside the convention center and outside in public was more like with a friendly small town full of helpful hosts.

The attendance was a little quieter, reflecting on the slower economy, and yet the traffic at our booth was stronger than we expected. We did have some time to visit with our current corporate partners and spark up a few new business deals.

We look forward to next year's Comfortech in Baltimore, hungry for some delicious crab.

On February 24th to 26th we were at the Fort Worth Convention Center in Fort Worth, Texas for the ACCA Conference and Indoor Air Expo. This conference is the #1 learning experience for HVACR contractors, because it's designed by contractors, for contractors.

Rhvac Helps with Manual S Compliance

Rhvac now includes an option that helps you both achieve and demonstrate compliance with ACCA's HVAC equipment selection publication, Manual S. The System Data window now lets you check a box that says that you in fact did select your equipment according to Manual S, which will add a section to your reports that states that to be the case. That statement on the reports is followed by a concise list of all the design parameters that are needed for selecting equipment using Manual S. You can read more about this feature on Rhvac's information page.

2009 AHR Expo in Chicago

We're back from the ASHRAE AHR Expo in Chicago, Illinois. We lucked out two ways: 1) the weather was cold (high near 14 degrees) but not as bad as it had been before our arrival, and 2) our expectations for less floor traffic were way too conservative - we generated enough floor sales to rival any typical "good year!" Of course, we Texans still enjoy the occasional snow as it is rare in our hometown, and our Chicagoland hosts were as friendly as ever.

Next year ASHRAE meets in Orlando, Florida. Bring the family for Disneyland when you visit with us about our HVAC software!

Chvac Allows Different Indoor Design Conditions for each Zone

Chvac now lets you enter different indoor design conditions for each zone in the system. Instead of all zones in an air handler having to be at the same indoor temperature, you can now enter a different design temperature for any zones whose indoor conditions vary from those of the air handler, for both summer and winter. When you enter a different indoor temperature for a particular zone, the program calculates the zone loads and airflow requirements based on the temperature specified for the zone. It also determines a new, adjusted indoor temperature to use for the air handler's psychrometric calculations. That new temperature is based on a precise weighted average of all the zone temperatures in the system. Click here to download the update and to start taking advantage of this highly requested feature.

2008 HVAC Comfortech in Atlanta, Georgia

Considering the down mood of the economy, we were pleasantly surprised that the first day of the show was busier than last year's! It's always a good sign when you get your first break and there's only twenty minutes left in the exhibition session, because you have been busy all that time.

For Day 2, you'll have to ask John, as I caught an early flight so I could make it home before the airports closed due to Hurricane Ike.

Luckily for Elite Software, Hurricane Ike missed our corporate headquarters by fifty miles. Our neighborhoods had some wind damage and received four inches of rain, but the worst effect was added delays in order shipments due to Houston's shipping hub having to recover from hurricane damage.

As usual, Atlanta was a model of southern hospitality, one that we will look forward to visiting the next time a trade show returns to Georgia's peach.

Elite Software hires TFTT founder John Walsh as National Sales Manager and National Trainer

Elite Software Development of College Station, TX has announced hiring John Walsh as their National Sales Manager and as their National Trainer.

John Walsh, principal of Training for the Trades (Ft. Wright, KY), will handle sales and marketing activities for Elite nationally.  In this capacity, John will be responsible for introducing the software through trade shows, meetings, sales calls to major corporations and other methods.

“Contractors are not always comfortable with computer software,” says Walsh. “But when they get a chance to actually try the programs in a classroom or web class setting, they understand how simple and powerful the programs really are.  More importantly, they find out how using HVAC software enhances their productivity and profit line.”

Walsh has also been a master distributor and trainer for Elite Software and assisted the company as a beta field tester for new programs.

As National Trainer, Walsh continues a tradition of providing training to the construction trades.  Among other training strengths that he brings to Elite are additional and diverse avenues of training.  For example, Walsh is co-author of "Hit the Load J," a simple, easy to understand book on Elite’s Rhvac Residential Heat Load program, as well as co-author to other publications on HVAC training.

Welcome to the family, John!


John Walsh is a 40 year veteran of the HVAC/R industry. He has been involved in HVAC and refrigeration sales and service, as both a business owner and a manufacturer’s rep. He was the owner/operator of Walsh Refrigeration on Cape Cod, MA, where he and his crew installed refrigeration units, including specially designed lobster tanks and environmental chambers, and HVAC systems.

The courses that he has provided include continuing education to HVAC, plumbing and electrical technicians. One of the most popular courses offered through Training for the Trades is on computerized heat loads. The class is offered on-site as well as through the web. Some of the classes are approved for continuing education in many states. The web class, which was designed to help technicians receive training when it is most convenient for them, has also been approved for Continuing Education in many states.

He has also taught in several vo-tech schools in New England, and has taught continuing education courses for the past 14 years.

2008 ACCA Annual Conference and Indoor Air Expo in Colorado Springs, Colorado

Ahh! The crisp mountain air, the sound of fresh snow crunching beneath your feet, and the luxury of one of the country's most beautiful resorts set the scene for ACCA's 40th Annual Meeting.

Located in Colorado Springs, near the Air Force Academy and NORAD's Cheyenne Mountain, our rooms in The Broadmoor provided us with a spectacular view of mountains covered in lush pine trees. Add to that a dusting of snow the first night, and attendees were treated to a delightful winter scene.

Of course, the real action was in the exhibits inside the convention hall and at the many technical seminars.

Elite Software announced Manual N support for our flagship Commercial Loads program, Chvac, and the entire booth staff couldn't miss attending the Manual N seminar hosted by Jack Bartell and Ken Watson, now that the new fifth edition Manual N has been released. We were just too busy to visit some of the technical sessions, but that one was a must, especially since the author, Hank Rutkowski, was present in the audience.

Our next major ACCA tradeshow will be the 41st Annual ACCA Conference at the Fort Worth Convention Center in Ft. Worth, Texas. The show will be from February 24th to 26th, 2009. Just a short drive from our headquarters, we look forward to the Texas-size commute and welcoming our guests to some real Texas hospitality, y'all hear? Click here for more details.

2008 AHR Expo in New York City

New York is sometimes thought to be a cold, unfriendly city, but our experiences last week during the 2008 ASHRAE show were nothing but positive. People on the street were polite and helpful (we got lost searching for Ground Zero and everyone we asked gave us directions), workers at the Jacob Javits convention center were helpful, and old customers visiting our booth were generous with their praise and even brought their friends over to start a new generation of customers.

Recession? Not here! Not only did we have strong on-floor sales and follow-up phone orders local to New York City and its boroughs and throughout the continental US, but we had all-time record international sales from far away countries like Philippines, Colombia, Egypt, Puerto Rico, Barbados (we volunteered to go install on-site!), Mexico, Brazil, Venezuela, Slovenija, Ecuador, Russia, and India.

We would like to add that the entire booth staff walked in the frigid cold from our hotel to Ground Zero. A moment of silence please. Deep and humbling, and rebuilding was busy late into the night. 'Nuf said.

Chvac Gets gbXML Feature

We've just added deluxe gbXML import and export ability to Chvac. The feature is really robust, in that we give you a lot of control over what happens during the import, including setting default material values, choosing which air handler and group to put imported zones into, and which spaces, surfaces and windows to include. And when you export a gbXML file from Chvac and then import it into AutoCAD MEP 2008, the Properties window will show Chvac's calculated results for both zones and spaces. Check out the new video on the Chvac page to learn more.

Comfortech 2007 in St. Louis, Missouri

We just got back from exhibiting at Comfortech 2007 in St Louis. The exhibit hall was not far from the Gateway Arch, an engineering marvel, and one of the evenings there was a social gathering for guests over at City Museum. As always, we had our share of new friends and old acquaintances visit with us at our booth. Next up: ASHRAE in New York City.

Big Improvements to Proposal Maker

The latest updates for Rhvac and Energy Audit include a lot of big improvements to Proposal Maker, including making it super easy to work with pictures, adding a spell checker and thesaurus, and making important improvements to most of the included templates and example projects. Both native pictures and picture fields are now much easier to resize and move (they have "grab handles" now), and you can now change the position style for any picture from "move with text" to "fixed position on page" and vice-versa. The behavior of picture fields is now much more consistent and predictable. The new spell checker includes a 250,000 word dictionary, and lets you add words to the custom dictionary.

In addition to the actual program enhancements, we've also posted several new instructional videos to help you get started.

Rhvac Built-in Duct Sizing Enhanced

We've just greatly enhanced the built-in duct sizing included with every purchase of Rhvac, which makes it so you can do a full Manual D duct design within Rhvac itself, without having to purchase additional licenses and draw your ducts with our Drawing Board and Manual D Ductsize programs. The Duct Static Pressure Loss Calculator window can now be fully linked to the airflow of rooms, zones and systems in the Rhvac project. And we've added a new Building Rotation Duct Size Preview window, which shows you the airflow requirements of each room or duct in the project in each of the eight possible rotation angles of the building, as well as the maximum duct size of all rotations.

2007 ACCA Annual Conference and Indoor Air Expo in Orlando, Florida

2007 AHR Expo in Dallas, Texas

This year's ASHRAE show was but a short drive from our headquarters in College Station. The weather in Dallas was mild for winter with just a hint of sleet, and spared us any slidin' ice.

Both US and international customers came in waves to view our wares and ask the good questions, keeping all our staff busy well past the closing hour. The end result: we made record sales and many new friends. If this was the off year, we can hardly wait for ASHRAE New York 2008!

Attendance at the the Comfortech 06 tradeshow in Baltimore, Maryland was good and we enjoyed getting to meet lots of new customers. And as always, we enjoyed talking with many of our old friends too.

AHR Expo 2006 in Chicago, Illinois

We're back from ASHRAE in Chicago, and although it snowed the day before we got there, no, we didn't freeze. Chicago was warmer than usual for late January, and the crowds at the show were also warmer than last year. We had a fun time, albeit busy, with many more visitors at our booth, including many old friends. No doubt about it, Chicago is a great place to meet.

Elite Software is looking forward to next year's ASHRAE show in Dallas. C'mon down for a little bit of Texas hospitality!

Duct Static Pressure Loss Calculator Window Added to Rhvac

Rhvac now includes a Duct Static Pressure Loss Calculator window that calculates duct sizes and the static pressure losses of your duct system. You can either enter your entire duct system, or just enough to calculate the fan static pressure requirement (one single route, or "path"). This unique tool includes a powerful Fitting Selector dialog, which makes it easy to select from hundreds of fittings from ACCA's Manual D.

If you're still using Rhvac version 6 you can update to version 8 for an upgrade fee. Check out the new features of version 8.

AHR 2005 in Orlando, Florida
