The Government’s Public Sector Decarbonisation Fund is a £1billion fund being made available now for the upgrade of public buildings and social housing to make them more energy-efficient and environmentally friendly. Projects with a focus on decarbonisation of heating and hot water will undoubtedly be a priority when granting funds as, according to 2019 figures issued by the Department for Business, Energy and Industrial Strategy (BEIS), heating, cooling, ventilating, and providing hot water and lighting for the built environment still generates 17% of greenhouse gas in the UK.
Part of a wider £3b plan to upgrade the UK’s buildings, the plan has been generally welcomed, as it is hoped to support up to 120,000 jobs across the construction sector, as well as boosting local investment through local job creation.
Designed to aid public sector organisations in England, including central government departments, agencies, local authorities, and especially schools and NHS Trusts. The plan’s intention is to improve buildings’ operational performance, reduce CO2 emissions, raise comfort levels for staff, plus reduce in building-related complaints and maintenance backlogs. This is to be achieved through the specification and installation of energy-efficient and low carbon heating measures.
However, the fund is only being made available for a single year, and since its announcement in July, has raised queries over whether government departments and local authorities have the time or resource to spend this effectively. Facility and energy managers responsible for public sector real estate should already be exploring their options for project design and delivery, not least because of the wider concerns over project timescales in the wake of Covid-19. It is, therefore, crucial to be scoping out retrofit projects as soon as possible.
At Adveco, we have almost 50 years’ experience supporting the refurbishment of public sector heating and hot water systems. While studies show that over the next two decades renewable energy sources (RES) – a mix of district heating, heat pumps, wind and solar energy – will be crucial to the energy supply in the heating market, we would lean towards more technology-open scenarios that not only predict large proportions of heat pumps but also assume the use of gaseous fuels. Just as electricity is becoming greener so too can the gaseous fuels which will contain larger shares of renewable ‘green’ hydrogen gas and other synthetic fuels by 2050. This supports the adoption of a hybrid approach that combines new and existing technologies, which we not only see as more practical but is both cost-effective and less influenced by the volatility of a RES electricity-only approach. The hybrid approach is especially valid when it comes to refurbishing old and inefficient systems, as well as extending viable systems where fresh demands outpace the original scope of the application.
From the latest high-efficiency, ultra-low emission condensing gas and water heaters to electric appliances, sustainable solar thermal and air source heat pumps, Adveco is deliberately positioned can support the introduction and integration of the latest technology. Typically, the latest generation of appliance not only is more efficient, but it can also offer a far more compact footprint, so makes refurbishment simpler, and without needing extensive building work to accommodate plant require less capital expenditure. If systems require scaling up to meet increased demands for heating and domestic hot water (DHW) then refurbishment can quickly become more complex, and if a hybrid system is employed, greater space may be required for the dual systems, as well as additional controls and pipework. Should the availability of space be an issue Adveco can design and build off-site prefabricated plant rooms that make full advantage of unused space, such as flat roofs, to expand capabilities.
If a hybrid heating system is chosen, it offers great advantages for cost-effective control, for example, a hybrid heat pump/gas boiler system is able to reduce the maximum power consumption of a system by smartly balancing the heat generators for greater efficiencies and lower operational costs whilst guaranteeing high system temperatures to ensure the comfort of those still living or working in the building during refurbishment work. And, by selecting the optimal (ecological) heat generator whenever possible (via an energy management system) it can also be optimised for CO2 emissions. Should the building envelope be renovated, the required heating load decreases and the existing gas boiler can take on less of the annual heating work, and it could eventually be put out of operation.
An extra £50m will fund social housing through a demonstrator project for the Social Housing Decarbonisation Fund (SHDF). This UK-wide demonstrator scheme will see grants supplied to upgrade the energy efficiency of over 2,000 of the worst-performing social homes. Again, Adveco has a long heritage designing and delivering multi-occupancy applications for heating and DHW.
To secure climate-neutral building stock by 2050, public sector facility managers desperately need help to achieve practical and cost-effective sustainability. At Adveco we can help with a full-service application design team who can provide an assessment of your properties’ demands and correctly size an application. We can help recommend the optimum appliances to deliver highly efficient systems that provide the best value in terms of capital and operational expenditure, whilst meeting the need to reduce emissions. Our commissioning service also ensures installation is carried out correctly and the system is safe to operate, which then unlocks long-term manufacturer quality warranty service.
