We are a Denver-based company dedicated to providing software and services for the building energy modeling industry. The company name reflects our mission to “help our clients reach new heights”.
Peter Ellis, President of Big Ladder, founded the company in 2009 after a six-year career at the National Renewable Energy Laboratory in Golden, Colorado. Today we are a team of programmers, engineers, and scientists with a unique combination of expertise in software development, computer simulation, and building science. Over the past several years, the company has experienced steady growth and achieved significant success and recognition in the industry.
We specialize in all things related to the EnergyPlus simulation engine. We provide software tools, training, support, and consulting services for EnergyPlus to mechanical, architectural, and design engineering firms across the US.
As a software company we handle all phases of software development: design, implementation, testing, documentation, support, and training. We have a special passion for open-source software. Our current open-source projects include Elements, Kiva, Modelkit/Params, Euclid, and an Atom package for EnergyPlus.
As members of the EnergyPlus Development Team, we have over 15 years of collective experience programming EnergyPlus. We have been involved with developing component algorithms, user interfaces, and other tools for EnergyPlus. As developers we are able to delve into the program source code to help debug users’ problems.
We currently offer various training workshops for professionals. We offer in-person public and private (in-house) EnergyPlus training workshops. We have trained hundreds of new users in the intricacies of EnergyPlus in workshops at US and international locations.
We offer public and private California Simulation Engine training workshops, where we teach CBECC-Res users about the intricacies of the input file that the underlying simulation engine (California Simulation Engine) uses for residential building design and compliance evaluation.
We exclusively use EnergyPlus and OpenStudio to perform whole-building energy modeling and have modeled numerous real-world buildings ranging from commercial to residential to US Army buildings. We specialize in complex projects and large-scale projects such as technology screening studies and market sector analyses.
