Estimate the annual electricity bill savings and payback period for an investment in a domestic solar PV system using this simple calculator. Simply answer six questions to estimate the payback period, it's that easy.Calculate the payback period
Interim NZEB Specification Tool
Calculate the Energy Performance Coefficient (EPC), Carbon Performance Coefficient (CPC) and the Renewable Energy Ratio (RER) based on the Interim NZEB Performance Specification for new buildings owned and occupied by Public Authorities. Art 9(a) of the Energy Performance of Buildings Directive for all new buildings to be Nearly Zero by 31ST December 2020 is being implemented through Part L of the Building Regulations.Use the NZEB Specification Tool
BER Research Tool
This tool gives you access to statistical data from the Building Energy Rating (BER) scheme. It provides access to information on all aspects of construction that affect the energy performance of dwellings. Data is updated nightly, so search results represent an up-to-date summary of published residential BERs. You must register to access the information.Use the BER Research Tool
National BER Register
Check the validity of a BER or DEC certificate. You will need to enter your BER/DEC number or the MPRN for the relevant of the building.Search the National BER Register
Energy Savings Calculator for Boiler Replacement Projects
This calculation tool will enable the user to estimate the annual savings associated with replacing all the existing boilers with high efficiency boilers in a LTHW single or multi boiler system. The calculation tool can only be used for multi boiler installations/systems in which all the existing boilers are identical types and all the replacement boilers are identical types.
Electric Motors and Variable Speed Drives Evaluation Tool
This tool is designed to assist organisations evaluate the benefits of retrofitting a range of high efficiency motors and/or VSDs.
Tubular Fluorescent Lighting and Controls Evaluation Tool
This tool is designed to assist organisations evaluate the benefits of retrofitting six types of T8 rated fluorescent fitting and conventional ballasts with high frequency T5 rated fittings and electronic ballasts and controls.
Pump Energy Efficiency Calculation Tool
This tool calculates the energy efficiency and energy performance of water (and waste water) pumping facilities.
Combined Heat and Power Primary Energy Savings Calculator
The CHP calculator should be used to calculate energy credits for the purposes of the Energy Efficiency Obligation Scheme (EEOS). Please note that SEAI will only accept savings from CHP projects that have been calculated using this tool.
