Why Comcheck Web is Better than Rescheck Web (2025)

Why Comcheck Web is Better than Rescheck Web

Why Comcheck Web is Better than Rescheck Web

Some people have been asking which software we prefer. The Department of Energy offers two options for energy audit software if you wish to perform the Comcheck or Rescheck online. These are options are Comcheck Web for commercial projects and Rescheck Web for residential projects.

So which do we think is better? Well at www.comcheck.net we deal mainly with the commercial side of projects so our answer is bias that we use and prefer Comcheck Web simply because if we performed our energy audits for a commercial project using the residential software product Rescheck Web we would ultimately have to do the project again in Comcheck Web to satisfy the building department.

What about functionality. One singular feature on Comcheck Web that is better than Rescheck Web is the copy feature. On Rescheck Web when you click “copy” of a component it then adds the tag “Copy 1” to the end of the item description. When you do the same function on Comcheck Web the “Copy 1” is absent from the new item saving you the step of going back and deleting this information from the item.

As far as codes go, right now Rescheck Web has the upper hand. Rescheck Web has the actual release of IECC 2021. Comcheck Web at the time of this article does not have IECC 2021 included in the code lineup. Anticipated release date is sometime this quarter. We are anxiously awaiting taking the IECC 2021 code for a Comcheck test drive when it is released and will bring you what ever findings we incur.

We appreciate you reading our Comcheck Energy Service blog. We try to specialize in all new related Comcheck Web and Comcheck Desktop as they pertain to creating Comcheck Energy Audits for building permits.

IECC Codes (2025) Available in Comcheck Desktop and Comcheck Web

Comcheck Energy Codes www.Comcheck.net

The Office of Energy Efficiency and Renewable Energy has created two fantastic softwares to allow you to create a Comcheck Energy Report for your New Construction, Alteration, or Addition to a Commercial Structure. The two softwares that they offer are Comcheck Web and Comcheck Desktop.

Your first option is to use the online version of Comcheck creating applications which is called Comcheck Web. You can access Comcheck Web here. Once there many users what to know exactly what energy codes are available within Comcheck Web online portal. The options are as follows:

2009 IECC, 2012 IECC, 2015 IECC AND 2018 IECC IECC. IECC 2021 is not added yet as of this blog post and anticipation is that it will be added very soon.

ASHRAE STANDARD 90.1-2007, 2010 Ashrae, 2013 Ashrae, 2016 Ashrae, 2019 Ashrae

There are also a plethra or city and state specific codes within Comcheck Web. Here they are

BOULDER, DENVER, DISTRICT OF COLUMBIA, FLORIDA, MASSACHUSETTS, NEW YORK CITY, NEW YORK STATE, NYSTRETCH, VERMONT, ONTARIO, AND PUERTO RICO

Now onto Comcheck Web’s little brother Comcheck Desktop. Comcheck Desktop is a great software for making Comchecks simply because it is stored on your local hard drive and then you can create Comchecks anywhere. Even when you are not connected to the internet. The major downside is that it is less frequently updated and does not have as many code options available as Comcheck Web. Here is a list of the codes that are available in Comcheck Desktop:

2009 IECC, 2012 IECC, 2015 IECC AND 2018 IECC. I do not anticipate IECC 2021 to be added to Comcheck Desktop but EnergyCodes.gov might surprise me.

90.1-2007 Ashrae, 2010 Ashrae, 2013 Ashrae, 2016 Ashrae

Comcheck Desktop also includes some specific State and City developed codes:

Boulder, Denver , NEW YORK CITY, NYSTRETCH, VERMONT, Ontario, and Puerto Rico

This concludes our Comcheck blog post on which codes are available within Comcheck Softwares for the end user to create Free Comcheck Reports. Thanks for reading the Comcheck blog.

How do you get a Comcheck Energy Report?

Basically there are 3 ways that you can obtain a Comcheck and we will discuss the ins and outs of each.

Your first option is to do it yourself.  For this option you will need to understand the calculations and most importantly the software.  The calculations are probably math you do on an everyday basis.  However, searching the plans, compiling the data correctly, and using the software properly takes some time to learn.  For this option plan about 10-14 hours per project to create your Comcheck properly.

The second option is to have it created by the architect or engineer that is drawing your original set of commercial construction blueprints.  They can take the information they have created designing your project and easily modify it to work for your Comcheck.  The one thing to consider with this option is that you must be working with a design firm that is familiar with Comcheck.  It seems basic that any designers would understand and implement Comcheck reports into their design process.  However, you have found your way to this Comcheck Energy Report blog so odds are your plans did not come with the report, which is very common.

The final option turns out to be the easiest and lowest cost.  You can hire Comcheck.net to create your Comcheck report for you.  All you need to do is email us a set of your construction prints along with a jobsite address to comcheck@comcheck.net we will take care of your Comcheck for you and return to you an invoice and overview of your project.  This whole process takes less than a day and we are ready and willing to help you with your project any time of day and any day of the week.  This process is super simple and smooth and we created it to be the easiest portion of your commercial construction project.

Reasons why you might need a Comcheck

At Comcheck.net we find several reasons that you might need a Comcheck Energy report on  your commercial construction project and we are going to discuss those here today.

The first reason is that the code in your jurisdiction requires one.  This is as cut and dry as it gets.  You are building a commercial structure in an area that uses the IECC 2009, IECC 2012, or IECC 2015 (possibly even IECC 2018).  The code requires the use of a Comcheck Energy Audit before you can begin construction.

The next reason would be that a particular building department official would like to see one for your project.  This can be for a multitude of reasons.  They may not understand your project well enough or he might just want to cover himself in the future by having a Comcheck on file with your building permit.

The final reason is that you are using a non-conventional product, material, or building supply to build the structure.  Many questions from the building inspector come from seeing new products for the first time.  If you are using an insulation product, window, or door that is uncommon in your area then odds are that the permitting office may want to see how it stacks up to your climate zone using a Comcheck Energy Report.

If you are in need of the Comcheck report to obtain your building permit you can email your plans to comcheck@comcheck.net and book your order here.

What is a Comcheck?  

A software package that connects all users of a commercial construction project to the energy side of the equation.  You enter insulation details, lighting, site location, and various other details and are given a score based on the materials chosen and how they compare to the climate zone.

Can I do the Comcheck myself?

If you understand the calculations and the software you can create your own Comcheck.  The issue most of our builders, architects, and engineers encounter is that they do not have time to learn a new suite of software to create the report correctly.  That is why we invented this low cost service using experts who use the DOE’s Comcheck software every day.

How long does it take?

We turn 100% of our projects around in 12-24 hours.
