BuildingSim

BuildingSim logo

BuildingSim allows users to model a building and analyze the heating and cooling energy costs in any climate. Users can create any building—from a one-room apartment up to a 100+ floor skyscraper--and account for everything from window coverings to shade trees. BuildingSim uses actual hourly weather data from over 90 climates around the world to numerically solve the full thermodynamic differential equations every minute of the year, giving the user the actual energy use down to the cent.

The simulation algorithm fully accounts for thermostat and HVAC controls, allowing the user to analyze the effects of different thermostat algorithms (programmable thermostats, setback, split-zone, etc.) on the energy costs for a specific building and climate. Screen Shots

Strengths

BuildingSim allows analysis of different thermostat and control strategies on energy cost.

Weaknesses

Simulation step size is small, so simulation time takes longer than some competitors.
