Services
Building Energy Modeling
We create detailed digital representations of building energy systems to predict performance and optimize efficiency. Our models analyze HVAC systems, lighting, insulation, and renewable energy integration across various climate zones. Using EnergyPlus and DOE-2 tools, we help clients meet ASHRAE standards and achieve LEED certification goals through accurate energy consumption forecasts.
Energy Code Development
We contribute to national energy efficiency standards through technical analysis and simulation-based assessments. Our work includes evaluating ASHRAE 90.1 revisions and supporting California's Title 24 compliance transitions. We develop common data definitions for HVAC systems and provide market impact analyses that shape regulatory frameworks for building energy performance.
Software Development
We create specialized applications for energy analysis and system optimization. Our portfolio includes DesiCalc for desiccant systems, Gas Cooling Guide for gas-fired chillers, and BCHP Screening Tool for combined heat and power systems. These tools feature parameterized DOE-2 input libraries that enable comparative analysis across 10-12 building types with automated reporting capabilities.
Software Testing
We conduct comprehensive testing for energy analysis software through regression, comparative, and empirical methods. Our services include test plan development, feature validation, and creation of standardized test suites. We maintain ASHRAE SSPC 140 compliance testing protocols and have performed EnergyPlus validation since 1999, ensuring software reliability for critical building performance calculations.
EnergyPlus Support
We offer priority technical support and customized training for EnergyPlus users. Our services include troubleshooting simulation issues, developing input files, and creating training materials. We maintain deep expertise in EnergyPlus features through active participation in development workshops and provide ongoing support for implementing new functionalities like life-cycle costing and thermal storage modeling.
