BTU stands for British Thermal Unit, measuring heat energy used by HVAC systems. One BTU equals heat needed to raise/lower one pound of water by one degree Fahrenheit. BTUs are standard for measuring energy transfer in heating and cooling appliances
International peer-reviewed journal on daylighting in buildings. Started in 2014, publishes bi-annually with 70-day publication time. Open access with no publication fees
Integrates EnergyPlus™ solver with BIM/3D modelling methods. Creates automatic building energy models from CAD/IFC files. Uses METEONORM climate data archive for quick model definition. Includes super-configurator for dynamic simulation scheduling
Degree day measures heating or cooling in buildings. Used for crop planting and pest management timing. Zero degree day indicates minimum energy consumption. Base temperature used is 2-3°C lower than typical indoor setting
EnergyPlus is an open-source energy analysis and thermal load simulation tool. Program calculates heating/cooling loads and energy consumption for buildings. Source code available on GitHub under permissive license
DOE-2 is a widely used freeware building energy analysis program. Predicts energy use and costs for all types of buildings. Uses user-provided building details and weather data for hourly simulations
