Luxury Domestic Sector Private Client, West Sussex, UK (Senior Partner of Fosters + Partners) At a Glance £5,900 / annum energy cost savings 91% / annum in energy savings Background New luxury domestic build (approx 3,500 sq ft./ 325 sqm) located in East Sussex, United Kingdom. Challenges GS Renewable Client, a senior member of Foster and Partners, did not wish to sacrifice internal space for mechanical services. Construction during the pandemic favoured off-site production to comply with COVID-19 restrictions. Integration of multiple technologies required to satisfy heating / cooling and hot water demand. Solution Our bespoke heat pump plant room satisfied the client's requirements while increasing living space in their new build. Our GS Renewable bespoke plant room installation has operating cost of £1800 / annum. Oil usage would have seen our client face operating cost of £6500 / annum. Following the success of our savings with the plant room, our client has requested a PV installation which further decrease the annual running cost by £1200 / annum. A total of £5900 saved on operational cost on a yearly basis upon project completion. Reach out

Estates Sector Hale House, Hale Park (Grade I Listed), UK At a Glance £22,990 / annum energy cost savings 66% / annum in energy savings Background Hale Park was built c.1715 by noted Baroque architect Thomas Archer (1668- 1743). Hale House (Grade I) listed stately home and wedding venue consists of c.100sqm of Drawing Rooms, and more than 500sqm of gardens and a church. The client wished to switch from oil fired heating and hot water to renewables. Challenges Installation in a Grade I listed building was not convenient due to restricted space and access. Construction in the buildings would have lead to disruption to the homeowners and the business. Multiple independent buildings on the grounds required services (House, North and South wing). Solution On-site consultation was carried out by GS Renewable consultation team. Our design team took into consideration the requirements and challenges faced by our client and designed a bespoke modular heat pump plant room. The modular plant room was assembled off-site and delivered on-site upon completion to reduce the disruption of running their business. The plant room was colour matched to RAL sample paint and sympathetically located on the grounds to blend into the background with the trees. It now powers our client's buildings with ground source energy for heating and hot water with cold water storage, filtration, pressurisation, solar thermal and planned Solar PV to follow.c Results Monetary figures below are based on today's price. The carbon reduction / year is 110 tonnes with a primary energy use reduction of 428MWh / year. By installing our bespoke modular heat pump plant room it had resulted in a 66% reduction in operating cost, it now costs our client an operating cost of £11,785 / annum. It would have cost our client £34,775 / annum to operate with oil. We expect the savings to double upon project completion. This project was shortlisted for the European Heat Pump Awards and attained Highly Commended status at the Heat Pump Awards in UK. Reach out
