Facility Electricity Intensity
Calculate annual electricity-only intensity and compare it with a reference you enter on the same floor-area basis.
Use facility electricity intensity →Generation Capacity Factor
Compare actual energy with continuous output at an entered constant capacity over the same period.
Use generation capacity factor →Savings Project Simple Payback
Separate annual gross savings from added operating cost and compare the net saving with upfront project cost.
Use savings project simple payback →Renewable Generation Value
Split entered generation into on-site use and export. Show export income separately from avoided grid purchases.
Use renewable generation value →Energy Unit Conversion
Convert an energy quantity between kWh, joules, megajoules, International Table Btu and a declared therm convention. Keep energy separate from power.
Use energy unit conversion →Power Conversion
Convert a known power value between watts (W), kilowatts (kW), mechanical horsepower (hp) and Btu IT per hour. Calculating electrical power from volts and amps is a different task that may also need power factor and phase details.
Use power conversion →Commercial Electricity Bill
Model one billing period with two sequential energy tiers, an entered billable demand, one fixed charge and a stated tax rule.
Use commercial electricity bill →Time-of-Use Electricity Cost
Hold total kWh and tariff rates constant while changing the share assigned to peak and off-peak periods.
Use time-of-use electricity cost →Battery Runtime Scenario
Apply usable share and one-way conversion efficiency to nominal DC energy, then divide available AC energy by a constant AC load.
Use battery runtime scenario →Fuel Cost per Input Energy
Turn your fuel unit price and heat content into input-energy cost, including a separate delivered-purchase perspective.
Use fuel cost per input energy →Useful Heating Cost
Use an entered output/input efficiency and matching fuel heat content to estimate metered fuel use and annual operating cost.
Use useful heating cost →Heat Pump vs Boiler Cost
Hold useful heat constant, apply an entered seasonal COP and boiler efficiency, then compare rounded energy and fixed operating costs.
Use heat pump vs boiler cost →Capital Project NPV, IRR & Payback
Compare three year-end project cash flows using NPV, year-end recovery checkpoints and an IRR only when the numerical method supports it.
Use capital project npv, irr & payback →Solar Levelized Cost of Energy
Divide a finite discounted cost schedule by discounted output using entered first-year generation and degradation.
Use solar levelized cost of energy →Battery Arbitrage Scenario
Price one supplied charge/discharge cycle after round-trip loss and a user-stated degradation allowance, then extend it over counted cycles.
Use battery arbitrage scenario →Electricity Demand Charge
Compare billed peaks after a supplied ratchet floor over a chosen number of identical billing periods.
Use electricity demand charge →Fuel Blend Energy Scenario
Sum two component heat contents on one matching mass or feed-volume basis and report a weighted input value.
Use fuel blend energy scenario →Fuel Volume to Energy
Convert a liquid volume to litres, then apply your supplied fuel heat content on its stated gross or net basis.
Use fuel volume to energy →Natural Gas Volume to Energy
Apply a supplied gas billing-volume factor and heating value, with explicit energy-unit conventions.
Use natural gas volume to energy →Entered Solar Resource Generation Scenario
Build a monthly capacity-times-resource scenario from your supplied peak-sun hours and loss factors, without a weather lookup.
Use entered solar resource generation scenario →Solar Self-Consumption Scenario
Calculate direct self-use, import and export inside three matching energy intervals before adding their totals.
Use solar self-consumption scenario →Energy Equipment Life-Cycle Cost
Compare two finite annual cost schedules including one stated replacement and an end-horizon residual value.
Use energy equipment life-cycle cost →Oil & Gas Production Value Scenario
Multiply oil and gas quantities by matching prices for one period and subtract only the deductions you enter.
Use oil & gas production value scenario →Solar Simple Payback
Calculate annual value from supplied self-use and export quantities, then compare positive net savings with net installed cost.
Use solar simple payback →Boiler Blowdown Energy Scenario
Thermal energy above the makeup state is blowdown kilograms × (blowdown enthalpy − makeup enthalpy) ÷ 3,600, giving kWh from kJ.
Use boiler blowdown energy scenario →Cooling Tower Concentration Ratios
Conductivity cycles = circulating conductivity ÷ makeup conductivity.
Use cooling tower concentration ratios →Cooling Tower Water Balance
Accounted makeup requirement is the sum of evaporation, blowdown, drift, leakage and overflow during one common period.
Use cooling tower water balance →Ideal Flash Steam Fraction
Ideal flash mass fraction = (initial liquid enthalpy − final saturated-liquid enthalpy) ÷ (final saturated-vapor enthalpy − final saturated-liquid enthalpy).
Use ideal flash steam fraction →Measured Heat Pump COP
Coefficient of performance is useful heating or cooling output divided by electrical input on matching energy and time boundaries.
Use measured heat pump cop →Ideal Gas Volume Scenario
The ideal-gas equation is pV = nRT.
Use ideal gas volume scenario →Before you use these calculations
Distinguish electrical input from useful mechanical or thermal output.
Use the actual billing period, tariff components and demand basis.
Keep projected savings separate from measured savings after installation.
Start with the example, replace the assumptions with your measurements, then change one input to see its effect. Save or export the scenario if you need to keep its basis.
