Estimate your building’s heating and cooling needs with clear inputs, visible assumptions, and a report you can keep.
Estimate peak heating and cooling loads from building details and design conditions. Review the breakdown, switch between US and metric units, and save or print your work.
Open load plannerCalculate air-state properties and compare process endpoints with explicit pressure, humidity and engineering limitations.
Open psychrometric analyzerScreen duct geometry, air velocity, Darcy–Weisbach friction loss and local resistance for preliminary fan and branch sizing.
Open duct plannerScreen water velocity, Reynolds number, Darcy–Weisbach friction loss, fitting loss and total pump head for preliminary hydronic design.
Open pipe plannerEstimate total dynamic head and power, then compare a user-supplied pump curve without fabricating vendor performance.
Open pump analyzerEstimate air-system pressure and fan power, then compare a sourced user fan curve without fabricating vendor performance.
Open fan analyzerConnect cooling load, water flow, pipe losses, pump head and a clearly labeled chiller COP scenario.
Open chilled-water plannerSeparate physical energy, energy charges and demand charges, then compare a documented efficiency scenario.
Open energy analyzerCalculate site EUI and place it against fixed illustrative quartile bands. Screening sketch only — not a surveyed dataset benchmark.
