Optimized Energy Design

Engineers

We are experts in simulation aided design of energy systems, sensors and algorithms for measurement and automation to measure performance. Our focus is on and advanced energy systems in buildings, however we also provide services for other structures such as greenhouses and provide industrial engineering for product development.  We optimize energy systems design in the built environment using simulation software such as the Energy Plus simulation engine with the Design Builder graphical user interface and jEplus parametric and optimization shell to aid in the design of low to net zero energy buildings.

Our work in modeling advanced energy systems in buildings has led us to a novel technology that presents an interesting opportunity and design challenge for the buildings of the future, namely Phase Change Materials for passive comfort control.  Our work modeling Phase Change Materials for a product major manufacture resulted in the requirement for a new model for the Energy Plus simulation engine circa 2013. In 2016 NRGsim Inc. won a competitive grant under the USDOE Small Business Vouchers Pilot program to provide energy modeling and software services for modeling phase change for building envelopes. The NREL press release can be found here.

In the long term; NRGsim Inc. is developing an open source, free-to-users web based energy modeling software platform and will provide software development services for energy modeling 'apps' in the near future. NRGsim software will connect to the smart thermostat hardware we are developing using low cost microcomputers and micro controllers with sensor arrays that controls building systems based the next day’s weather data and an Energy Plus predictive model that is corrected by sensor and occupant feedback.
