Calculators
Home energy audit
heat loss by element → class
Wall insulation
thickness to R=3.3 + payback
Window replacement
heat loss old vs new
Heat loss
through the envelope (U×A×ΔT) → required boiler power
Heating comparison
UAH/kWh: gas/electric/HP/wood/pellets
Heat pump
sizing + payback vs gas/electric
Two-zone meter
savings from day/night tariff
Electricity
Appliance energy usage calculator
LED savings
LED replacement calculator: count, wattage, hours — yearly savings
Saving habits
habits with real effect: kWh and UAH per year each
Gov programs
'warm loans', insulation grants, compensations — program map
Eco bonuses
Bank and government energy-efficiency programmes: discounts, cashback, soft loans
Heat recovery
ventilation heat saved + payback
Rainwater
roof × rainfall → liters and tank
Water
Consumption norms and cost
Heating automation
thermostats, zoning, schedules — how much temperature control saves
Energy class
kWh/m²·yr → class A+–F
Tariff comparison
yearly electricity cost: single vs two-zone tariff
Seasonal prep
home checklists for winter and summer: what actually affects bills
Chimney & ventilation
Heat loss through flues and ventilation: draft, dampers, recuperation
Metering
heat meter, two-zone meter — when they pay back
