In its first incarnation, LoopLink® was the name we put on our residential and light commercial geothermal design software. Over time, we thought up great services that were related to LoopLink® RLC but needed to be separately accessible because of who they would best serve.
Last year, 2015, became the year that we had to figure out how to deal with some of those ideas. More to the point, we had to figure out what to call them. We wrote lists and lists of names but none of them seemed to stand up. Maybe it was just how comfortable we were with the sound of 'LoopLink' but nothing else seemed to fit.
In the end, we decided to create some short term confusion and keep LoopLink as the family name while adding a short descriptor to the end to distinguish each product in the family. Ultimately this makes a lot of sense because the services share resources. Here is how things break down:
LoopLink® RLC
Our flagship service, LoopLink® RLC is designed for the Residential and Light Commercial geothermal design market. It is a powerful web-based software service that helps system designers size loopfields and do advanced economic analysis for homes and office spaces.
It is built specifically for designing ground heat exchangers for buildings with low occupancy schedules, negligible internal gains and low to moderate ventilation requirements. Basically, anything you can reasonably model using ACCA Manual J.
LoopLink® PRO
LoopLink® PRO is also a web-based ground loop design service but it is specifically designed to handle commercial building loads. PRO is built to be extremely flexible and handle designs that range in complexity from a simple block load all the way out to campus systems with each building broken into individual zones.
Buildings requiring detailed load analysis with tools like eQuest or TRANE Trace are what we designed PRO to handle.
LoopLink® GSE
LoopLink® GSE is our geothermal savings estimation service. It allows companies large and small to access a powerful performance estimation engine without having to maintain their own estimation models. Subscribers to the service build their own interfaces and submit data including location, square footage and a few other variables. GSE looks up the location, figures out the typical local weather and estimates the energy and cost of heating and cooling the space with geothermal vs. a traditional comfort system.
