Heat Pump and Heat Loss Indicator Research Pilot

Description

The objective of this Request for Tender is to appoint a suitable service provider to conduct field research into the efficacy of installing heat pumps in homes at varying Heat Loss Indicator (HLI) levels up to a maximum of 3.0 W/K/m2. The project will work across a range of building cohorts and types taking account of the typology of the residential market and typical occupancy characteristics. A range of influencing factors such as the internal temperature profile, the heat distribution and emitter design, the sizing of the heat pump unit and user behaviour and operation will also be taken into account. The high-level objectives of this study include the following: 1. Compare the impact on energy consumption, costs and carbon emissions for a cohort of homes who install heat pumps and energy efficiency measures with a similar group of homes who do not; 2. Compare the impact on energy consumption, costs and carbon emissions for a cohort of homes who install heat pumps across at different HLI bands; 3. Undertake an assessment of heat pump operating profiles, set temperatures and energy profiles based on detailed monitoring data; 4. Assess homeowner experience, comfort and satisfaction through surveys and case-studies of a range of study participants; 5. Generalise results to wider Irish building stock.
