4. What is a Superhome?
Achieving 65% Energy Reduction

5. Superhomes 2.0
• 2 Year Research Project led by LIT
• Commenced April 2017 with industrial partners
• Tipperary Energy Agency CLG
• ESB Innovation and Electric Ireland
• ESB Networks
Aim to develop smart solutions supporting ASHP
Optimisation and the Deep Retrofit market in Ireland

• Using extensive data analysis from 20 real buildings
• Superhomes upgrades completed in 2015 & 2016
• ASHP Optimisation across 15 buildings
• PV integration across 10 buildings
• ToU assessment across 10 buildings
• Requires engagement of homeowners – pride!

10. Year 1 Findings
• ASHP have performed to high standards and Homeowner satisfaction
is extremely high
• Education of homeowners on operating approaches (Flow vs Curve)
an on-going process
• Further integration of PV output with ASHP with current Superhomes
design is not viable
• Operating profiles of ASHP varies but emerging optimisation
opportunities
• Optimisation measures can achieve a further 10-15% improvement

11. Next Phases (2018/2019)
• Installation of ASHP Opto Unit in 10 homes (planned
June/July 2018)
• Testing and analysis for heating seasons 2018/19
• Deploy specific Electric Ireland Meter with pilot HP Tariff
• Encourage load shift from 6-9pm peak
• Determine homeowner response to price signals
• Develop Superhomes 3.0 Design which integrates PV & EV
• Best Practice Guide for ASHP installation in nZEB Retrofits.
• Business Development & Commercialisation
