To provide heating and hot running water to main building.

A ‘new build’ multi-occupancy office workspace in the Midlands, comprising 20 office units each approximately 20m²/180sq.ft. with communal areas, small reception and corridors giving a total area of 600m²/5400 sq.ft.

To enhance the ‘green credentials’ of the building that benefitted from high ‘U’ rating, a roof mounted 20kW solar PV array with battery storage, the property developers required Air Source Heat Pumps [ASHP] to provide heating and hot water for the building.

Additionally, a provision for cooling the working areas during the summer was also required as the main façade of building was predominantly south facing.

The project team were involved at the planning stage of the development and were instrumental in developing the format of the heating system at the site.

Information was collated in respect of anticipated hot water usage and any daily peaks in demand plus seasonal heating requirements.

The renewable solution that the developers commissioned from us was:

• The installation of a 40kW ASHP

• The site has achieved its low carbon emissions status.
• The site has only a low requirement for fossil fuel generated energy.
• Surplus electricity from the PV array is fed back into the Grid, providing power for others and income for the business.
• Whilst there is still a need for connection to the Grid for electricity, this is only utilised at a low level, during the early mornings and evenings with a slight increase during the winter months, with the battery providing reliable back up for such times.
