Energy — Ireland
Compare energy quantities, installed capacity and cash flows separately. Supplier tariffs, local design conditions and confirmed incentives belong in separate inputs; electricity used and electricity exported need not have the same value. This directory groups energy tools for Ireland; individual pages state their supported inputs and limitations.
Start with these tools
Solar Savings Calculator — Ireland
Estimate the financial effect of a specified rooftop solar scenario, with exported electricity valued separately from electricity used in the home. EUR planning view; stated limitations apply.
Heat Pump Sizing Calculator — Ireland
Translate an already assessed design load into a manufacturer-rating requirement at the local cold-weather performance point. EUR planning view; stated limitations apply.
Insulation Upgrade Calculator — Ireland
Estimate the effect of an explicitly specified resistance upgrade on a building surface. EUR planning view; stated limitations apply.
Solar Panel Sizing Calculator — Ireland
Translate a site-specific annual energy target into a rounded panel count and a transparent material-cost scenario. EUR planning view; stated limitations apply.
Solar Battery Sizing Calculator — Ireland
Size an energy reserve for an explicitly selected critical load, rather than assume that the battery can supply every household circuit. EUR planning view; stated limitations apply.
Open a tool, check the displayed formula and enter values from the same period and measurement system. Currency defaults to EUR. Where a form offers metric and imperial units, changing the selector converts the entered measurements rather than relabeling the same number. Dated reference components are shown with their sources; unverified rules and prices are not silently treated as current local facts. Save distinct assumptions as separate scenarios and compare their inputs before their outputs. Shared links can disclose the input values they contain. The implemented expansion is still subject to its published scope-acceptance checks, including missing regional datasets and production-browser verification.

Compare the fuel-cost consequence of two seasonal efficiencies at the same useful heating load. EUR planning view; stated limitations apply.
Electric Radiant Floor Calculator — Ireland
Calculate the connected load and a scheduled-use energy scenario for electric resistance floor heating. EUR planning view; stated limitations apply.

insulation sub
Insulation Upgrade Calculator — Ireland
Estimate the effect of an explicitly specified resistance upgrade on a building surface. EUR planning view; stated limitations apply.
Attic Insulation Calculator — Ireland
Estimate attic insulation quantity and heating savings while keeping moisture, ventilation and local resistance requirements outside the arithmetic. EUR planning view; stated limitations apply.

Frequently asked questions
Does this directory imply full local-rule coverage?
No. Each calculator states its scope. An implemented mathematical worksheet is not the same as a fully researched statutory calculator.
Where do the amounts come from?
Either your inputs or an explicitly named and dated reference component. Illustrative defaults are not supplier quotes or market averages.
Can I compare assumptions?
Use the individual calculator’s scenario controls. Read its formula, period, units and limitations before comparing results.
