ARBETA

The project at Arbeta was designed to implement a carbon reduction scheme within a live accommodation block, with a focus on minimising disruption to residents while substantially enhancing the building’s energy efficiency. The work included the installation of photovoltaic (PV) panels and advanced air source heat pumps (ASHPs), selected for their effectiveness in reducing carbon emissions and improving energy performance. In support of these systems, targeted modifications and upgrades were undertaken on the building’s electrical incoming supply and low-voltage (LV) distribution network to ensure that the power requirements for the air source heat pumps were fully accommodated.

In addition to these measures, LED lighting was installed to replace existing fixtures, generating further energy savings through improved efficiency. New heat emitters were also integrated as part of the upgrades to the heating system, enhancing overall performance. During these modifications, a temporary boiler was deployed to maintain uninterrupted heating and hot water services, ensuring residents experienced no reduction in comfort or access to essential services.

A key feature of the project was the installation of the industry-leading Clade ASHP, which operates efficiently across a broad temperature range from -5℃ to +80℃. This system was chosen for its compatibility with the existing wet radiator system, enabling the building’s heating infrastructure to achieve both efficiency and sustainability without requiring major alterations to the established system. This project successfully incorporated advanced energy solutions, yielding significant carbon reductions and increased energy efficiency while preserving operational continuity and resident comfort.
