LoopLink GSE Update

Monday, November 20, 2017

Our geothermal savings estimation API, LoopLink GSE, recently received an update to improve accuracy and performance. We will start with what got better then talk a little about technical changes that will impact customer implementations.>

More Accurate Utility Rates

In version 1 of the GSE API, we took statewide average utility rates and applied them to any search which didn’t include custom rates. In this update, we now search (in the US only) for local electric rates and apply those to the estimate. So, if your customer searches their home address we can typically identify the correct electric utility provider and rate.

We have yet to find a house level rate lookup tool for natural gas, fuel oil or propane. So those energy prices are still a statewide or regional average depending on data availability.

We know it isn’t optimal but due to the difficulty in finding consistent information for all countries, searches outside the US will resolve to the US national average for a given energy type. As demand increases in other countries we will look to improving our defaults. For now, know that if you intend to support other countries your best results will come from asking the homeowner for utility pricing.

Know the Place?

A place object has been added to the response which enables you to identify the location we found for the estimate. At first blush this doesn’t seem that valuable. After all, the user provided the location to initiate the request. The value is that now you have a way to provide feedback to the user to ensure that the place we found was in fact the place they searched.

Technical Note: We moved geocoding attribution data into this object… it just made logical sense to tie the attribution to the result.

Updated Load Model

We are always looking at our load model and working to provide more accurate results with the limited information we require from homeowners. In this update we did more work on tweaking our advanced parameters to account for duct placement, seal and insulation in a more accurate way.

Better Security and Accounting

Version 1 was a little naive in its implementation of Cross Origin Request Sharing (CORS). We have bolstered this method and improved our ability to identify sites that are registered to make requests as well as improved the accuracy of our per site request counts. This will greatly simplify your ability to make requests against our system and allow us to provide you with more accurate usage statistics.

Logging and Retrieval

We noticed that an awful lot of homeowners come back and enter the exact same information into the system multiple times. Rather than rerun these requests we have implemented a logging function that will store requests for up to one month.

We provide a unique estimate ID with each response that can be requested directly. So, now you can get a homeowner’s email and send them a link back to their estimated savings or send a local dealer a copy of the link with the homeowner estimate.

We do not accept or store contact information so it is up to your team to fill in those blanks.


In LoopLink GSE 1.0 we required all requests to be sent as a POST. This is no longer the case. You may now submit your data with a GET or POST. All other request methods are restricted.

Change Your Request Structure

In our first iteration we tried to build GSE to be as permissive as possible. We allowed users to just send us a location field that contained anything from a complete address to just a postal code. The tool worked but the search was buggy and while it always returned a result, the result may have been for the wrong place entirely.

To deal with this issue, we now ask for structured requests so we can more efficiently and precisely search locations. So what was previously sent to us as:

Is now sent as:

You don’t necessarily need to send us every piece of information but we we now require that you include the country in a search based strictly on postal code.

Search Coordinates Directly

In the ideal interface, your user will run a location search in the browser through Google Maps or a service like Zillow (which provides some square footage information). Which means there isn’t a good reason for us to geocode the location on our end. You can send us coordinates directly which does speed up many of our results. Just remember that any search containing ‘lat’ and ‘lon’ fields will be reverse geocoded to establish rates and other location information.

In the update, you no longer need to provide the ‘geocoded’ flag. We automatically detect the 'lat' and 'lon' fields and handle the request accordingly.

3 Ways Geothermal Design Software Improves Your Sales Pitch

Friday, November 17, 2017 Experienced geothermal contractors know the importance of building value with their prospective customers. While that value can be demonstrated in many ways, contractors should not overlook the importance of using geothermal design software to help them win the job. When you sell geothermal comfort systems, you need to show your prospects that they can make a seamless transition to the new system and that its higher cost will pay off in the long run.

Geothermal design software can do just that. Homeowners considering a geothermal system to replace an aging HVAC system want it to be easy. Your prospective customers know just enough about the technology to expect a higher level of “engineering” than in a standard HVAC system. They need confirmation that you designed and sized the job correctly without overcharging.

Using geothermal design software can demonstrate to your customers that you’re the expert and that they can trust you to simplify their transition to geothermal heating and cooling. Here are three reasons why.

1 Using Geothermal Design Software Demonstrates and Confirms You Chose the Right Unit

“Old school” or “rules-of-thumb” sizing techniques commonly employed by those without geothermal design software are problematic.

Oversizing a geothermal unit is much more expensive than oversizing a gas furnace. Doing so could price you out of a job.

Undersizing the unit will require excessive backup heat, eliminating energy savings. Your customer doesn’t want the auxiliary heat activated when it’s 35 degrees outside. Sizing a smaller unit than competitors may get you the job, but the homeowner won’t be satisfied with the purchase if energy savings are lacking. That might cost you a referral.

2Using Geothermal Design Software Demonstrates and Confirms You Sized the Loop Correctly

Rules-of-thumb don’t work for sizing loops, either.

Overestimating the loop size raises the price for the homeowner while underestimating it may cause excessive loop temperatures, reducing capacity and efficiency. Excessive loop temperatures may cause unit lock-outs and require emergency heat in the winter, or failure to cool during the summer.

Many geothermal dealers rely on loop contractors to size and build the loop. This can be risky. Even if you sub-contract the loop installation, use geothermal design software for sizing the unit and the loopfield. At the end of the day, it is the HVAC installer not the loop contractor holding the bag if a system fails.

3 Using Geothermal Design Software Demonstrates and Confirms Long Term Value

Homeowners invest in a geothermal system to save money on their utility bills. Geothermal design software demonstrates that savings with head-to-head comparisons of various options for that customer’s home. With local fuel rates and estimated efficiencies, geothermal software will be make running simple payback and 30-year saving analysis quick and easy. Kent Kuffner

Geothermal Can Change The World


By, Doug Carruthers Geothermal heating and cooling systems are sold to homeowners and building owners with a focus on how their system will improve their lives. The direct benefits and individual case is a critical part of making the sale but its not the only set of benefits you should present.

Don't forget that many consumers interested in geothermal are often just as interested in the big picture truth that geothermal can change the world. Every GSHP system improves our energy future and here are some numbers to help you back that up.

Pure Energy

The United States uses nearly 25% of the world’s energy but only represents about 5% of the world’s population. At the residential level, more than 70% of home energy use is for space conditioning and hot water generation.

A 2010 study from Oak Ridge National laboratories found that if we could convert every single family home in the U.S. to using geothermal for heating, cooling and hot water generation, it would save 4.2 Quadrillion Btus annually (4,200,000,000,000,000 Btu for those who need to see the full number...that’s a lot of commas). This is based on reducing the consumption of all forms of energy for space conditioning and hot water heating (natural gas, propane, oil, electricity, etc.).

That amount of energy is equivalent to 1.2 trillion kWh (1,230,898,494,723 kWh). For perspective, the total residential sales of electricity in the U.S. amounted to 1.4 trillion kWh in 2015. Not a bad start to reducing energy consumption.

Less Gassy

Even compared to homes using electricity for heating/cooling, geothermal emits less upstream greenhouse gases simply because it consumes less energy. Check out the estimated difference below.

11 therm = 100,000 Btu (Source Dandelion)

According to the EPA, the average house is responsible for twice as many greenhouse gas emissions as the average car. Based just on the pure energy savings GSHPs clearly translate to a massive reduction in greenhouse gases (GHG).

How big?

Oak Ridge National laboratories puts the estimated CO2 reduction at 271.7 million metric tons annually. According to EPA estimates that is equivalent to taking 58 million cars off the road.

What About The Benjamins?

Oak Ridge estimates that at 100% adoption for single family homes, homeowners could save as much as $52.2 Billion dollars per year with geothermal. That is a stack of one hundred dollar bills 35 miles tall. That is A LOT of Benjamins.

Tell Everyone!

If the world really wants to take a bite out of greenhouse gases and get a handle on global energy consumption, geothermal heating and cooling brings us a long way towards that reality. Solar, wind and every other green technology that is kicking the pants off of geothermal in sales falls far short of the impact that can be realized with geothermal alone.

More importantly, geothermal supports all of the other renewable energy technologies. Solar and wind proponents should be screaming from their rooftops for the world to adopt geothermal. Because geothermal automatically drops off the peak summer demand by at least 30% which means a larger percentage of the national baseload can be generated by renewables.

Depending on who you ask, the estimated geothermal market share currently hovers around 1-2%. Imagine if we could bump that to 5% by replacing half of the propane and oil furnaces in the U.S. It would save the homeowners money, save an astronomical amount of energy and reduce GHG significantly more than those same homeowners buying electric cars.

Geothermal is the right technology to reshape our energy future. It’s a shame we have to bury it.
