Armstrong Point is the first zero-energy cost business park in the UK using numerous low and zero carbon technologies in order to become a net-producer of energy. The units range from 1367 ft² to 23,389 ft².

Technologies include wind turbine, transpired solar collectors, solar thermal hot water, air source heat pumps, LED lighting, photovoltaic arrays and rainwater harvesting for irrigation and vehicle washing. A central energy generation and use monitoring display was installed within each unit to inform the tenants of current and past energy use, ensuring 100% heat delivery by Heat Pumps

Gwynedd County Council instructed a high level analysis of roof mounted PV generation capacity across a number of sites to establish the full potential of PV generation.

The key purpose of the exercise was to optimise PV generation alongside site consumption, with an overall aim of using as much consumption on site as possible to maximise the return on the investment.

Sites are to be provided with large battery storage which in turn will be utilised to power EV charging points made available to community service vehicles. This will in turn help to provide free hospital and other essential transport services to elderly and vulnerable residents living in rural communities.

Viridian were appointed by Newcastle City Council, to decarbonise the heating systems for 7Nr schools in the Newcastle area, to assist them in achieving their target of achieving net zero carbon emissions by 2030.

Results were achieved by converting from gas heating to heat pumps, and achieved the following objectives;

• Driving down energy consumption (fabric first);
• Adoption of best practice in
• Removal of the existing gas boilers
• Consider the option for heat pumps + (existing) biomass boiler back-up
• Optimal Heat Pump sizing - Capex vs Carbon saving vs Opex

With the use of specialist design and simulation software, the HVAC installations were designed and optimised by means of a dynamic calculation and simulation model, bringing complete transparency to the hydraulic and energy related performance of the system through measurement against KPI’s relating to costs, carbon emissions and comfort.

This project for the Principle Building Surveyor at, involved the replacement of the existing gas fired heating, hot water and pool heating plant, with highly efficient Air Source Heat Pumps.

Our services involved an initial detailed Site Survey to better understand the site, it’s existing services and pipework arrangement to facilitate the future installation and associated pipework amendments. A review of the site survey information, including half hourly metering data, was undertaken alongside thermal performance calculations to allow a review of potential heat pump technologies.

Viridian were employed to help reinstate the mechanical, electrical and public health installations at the Church of The Ascension following a major fire.

The chuch was sympathetically re-built as a community hub, with flexible spaces, including nursery, café area and Worship areas. The space now benefits from the latest technologies feeding an underfloor heating system dicteted by the end use of the facility requiring low surface temperatures. At the time of the reopening of the church the project received widespread pubilcity including ITV news coverage .

Viridian were instructed to produce a zero-carbon roadmap for this multi-occupancy office in Gaerwen, Anglesey. The works involved a review of historic energy bills from the existing services installations.

Recommendations included the replacement of the existing gas fired heating and hot water plant, with air source heat pumps, which together with the installation of Photovoltaic Panels ensured the achievment of zero carbon emission targets within 2 years.

Appointed to assist Calderdale Council, Viridian were involved in the preparation and application required to gain Salix PSDS grant funding to replace the existing gas burning heating plant with air source heat pumps.

Our services involved analysing existing operational data to determine the optimal solution and system parameters, undertaking thermal loading calculations, and producing detailed drawings and schematics of the new heat pump heating system. The solution incorporated small modular heat pumps housed within containers on the roof of the building to minimise the visual impact of the new plant. The systems hydraulic perameters were optimised to retain as much of the existing pipework and emitter infrastructure as possible.

Our services involved analysing existing operational data to determine the optimal solution and system parameters, undertaking thermal loading calculations, and producing detailed drawings and schematics of the new heat pump heating system. The solution required a sympathetic approach to the listed nature of the building in order to minimise the impact on the buildings facade and natural lighting through the glass roof. The system incorporated a concealed purpose built plant deck to house the air source heat pumps and wholesale replacement of emitters to reduce their visual impact within the building.
