Carbon Footprint Calculator
Estimate carbon emissions from energy, transport, and household activity.
Solar Production Schedule Calculator
Project year-one generation from installed size and specific yield, degrade production annually, escalate electricity value separately, and tabulate annual and cumulative...
Rainwater Harvesting Trend Calculator
Project a rainwater-harvesting trend by compounding annual rainfall change and translating each year into catchment yield and demand coverage.
Rain Garden Runoff Storage Planner Calculator
Calculate net rain-garden storage need from treated area and the entered rate, gross it up for application efficiency and field loss, round purchase packages upward, and...
Water Footprint Calculator
Add direct daily shower, toilet, and other household water use, then annualize and divide by household size.
Home Baseload Energy Calculator
Convert home baseload rated power, operating hours and load factor into daily, monthly and annual energy use, utility cost, comparison savings, energy reduction, and a simple...
Rainwater Harvesting Offset Calculator
Cap annual rainwater offset at entered demand, translate the offset into avoided water charges, and compare system cost with maintenance and a transparent rate-change scenario.
Household Water Savings Impact Calculator
Apply fixture and behavior savings sequentially, then subtract separately entered rainwater and greywater reuse before valuing potable-water reduction.
Rainwater Harvesting Consumption Calculator
Run a monthly storage ledger that caps the tank, records overflow, serves indoor and outdoor demand, and accumulates any unmet demand across the selected horizon.
Rainwater Harvesting Forecast Calculator
Forecast catchment yield and entered non-potable demand independently across each month, then compare cumulative supply, demand, and tank-capacity turnover.
Household Water Consumption Calculator
Convert daily and weekly household activities to one daily basis, add other use, and calculate per-person and annual consumption.
Stormwater Runoff Volume Calculator
Convert effective rainfall depth over an entered drainage area to volume, apply a composite runoff coefficient, and reconcile release, storage, overflow, and average flow.
Biodiversity Index Calculator
Calculate Simpson and Shannon diversity from four entered abundance counts and convert Shannon entropy to an effective species count.
VividRainwater Harvesting Calculator
Use one liter per square meter per millimeter of rain and apply collection efficiency to estimate harvest potential.
Rain Garden Sizing Calculator
Translate captured runoff to volume and divide by the combined entered ponding and drawdown-infiltration depth, then apply an explicit area safety factor.
Solar Energy Production Calculator
Multiply array capacity by peak sun hours and performance ratio, then annualize across operating days.
Greywater Reuse Calculator
Average shower and laundry source volumes to a daily basis, apply recovery efficiency, cap reuse by entered demand, and size a simple storage coverage volume.
Rainwater Harvesting Impact Calculator
Model rainwater harvesting impact by capping collectible rainfall at entered demand, converting it to avoided charges, and separately reconciling operational-carbon...
Home Energy Cost Calculator
Multiply each energy quantity by its unit rate, add fixed charges, and annualize the monthly estimate.
Landfill Diversion Calculator
Apply separate capture rates to recyclable, organic, and reusable streams, subtract entered contamination, and reconcile net diversion with landfill tonnage.
Rainwater Tank Capacity Calculator
Translate one design rainfall event into gross and net capture, enforce tank reserve and capacity, then compare usable storage with a stated dry-period demand.
Rainwater Harvesting Scenario Calculator
Compare two rainwater-harvesting catchment, rainfall, runoff, and storage designs while keeping annual demand common and clearly labeled.

Set the environmental boundary before estimating impact
Ecology and environment calculators estimate energy, emissions, water use, rainfall capture, waste, populations, habitat measures, and environmental trends. Meaningful results depend on a clearly defined place, period, and system boundary.
Use local emissions factors, climate data, energy mix, rainfall, and ecological baselines where available. An inventory of water, energy, or emissions is a useful quantity but is not by itself a complete life-cycle or environmental-impact assessment.
