BSEE ENERGY MANAGEMENT


uThe Jaga Bespoke Maxi LST was specifled for a heang upgrade at the Royal Hospital Chelsea. It conforms to NHS Estates Health Guidance Notes on both surface temperature and casing design. Always cool to touch, irrespecve of high fiow temperatures, it prevents the risk of burn and its curved edges decrease the likelihood of injury through a fall

CARE HOMES MUST UPGRADE TO SAVE Making economical and safe heating choices


O


Phil Mangnall, managing director at Jaga UK, argues that, by invesng in energy ecient and sustainable heang soluons, care home owners can improve living standards and save money in the process





When selecng a new system, operators need to look beyond inial costs and instead assess the lifeme cost to find out which will generate the best return on investment. One opon is for care homes to generate their own power, and opportunies include solar, wind and heat pumps – to name but a few.


perating around the clock, care homes are massive consumers of energy – in


particular heating


and hot water. Because older and vulnerable residents are often sensitive to the cold, the temperature needs to be high compared to the average domestic home and the 24/7 occupancy rate means that the heating is constantly on. Not only that, but the nature of a healthcare environment means a large amount of hot water is required and there is a constant cycle of washing.


The result is that facility managers, already under pressure from rising staff costs, can come in for a shock when the energy bill arrives. According to the Carbon Trust, the UK’s healthcare sector spends £400 million per year on energy and a significant proportion of this is being wasted.


Inefficiency can also have a detrimental affect on the environment. A typical 30 bed care home categorised as fair, using 320kWh/m2 gas and 50 kWh/m2


be responsible for the emission of over 120 tonnes of CO2 every year. So, energy efficiency should be high on the priority list.


We recently surveyed facilities managers across a range of sectors, including care homes, to find out how they are tackling energy efficiency. The study found that space heating is the largest component of the energy bill for almost a third (32 per cent) of respondents.


For care homes and other supported living providers, simply reducing the amount of energy used is not an option. Efficiency measures need to be put in place to reduce overheads while maintaining and comfortable and safe environment for all.


Undertake an audit ’


The first step on the road to effective energy management and efficiency is to undertake an audit that analyses current energy spend and identifies potential opportunities to make savings. All care homes will be different in terms of energy output, operations and processes. Working with a contractor to do this can help to identify the best technologies to incorporate and where to install them.


For example, implementing something as simple as a more efficient lighting or heating and ventilation system could save a care home a vast amount of money in the long term that could ultimately be reinvested in improving patient care.


When selecting a new system, operators need to look beyond initial costs and instead assess the lifetime cost to find out which will generate the best return on investment. One option is for care homes to generate their own power, and opportunities include solar, wind and heat pumps – to name but a few.


Biomass boilers are also a potential replacement for oil/gas boilers in order to generate heat. As well as qualifying for subsidies through the Government’s Renewable Heat Incentive (RHI), these boilers could reduce yearly bills by almost 50 per cent.


Upgrading the heating system will have a positive impact on overall energy efficiency, however, to amplify this effect managers should also consider the heat emitters which partner with them.


of of electricity would


In our survey an overwhelming majority (97 per cent) said the efficiency of a heating emitter, such as a radiator, is important. A technology that can deliver important savings is the Low-H2O radiator, which is up to 15 per cent more economical compared to standard steel-panel radiators, according to tests carried out by independent body BRE. This is because the heat exchangers are constructed from super-thin, ultra-light sheets of aluminium and copper (55 fins per foot of heat exchanger).


Faster reaction times


A major benefit of low water content radiators in a care home environment is that they react much faster when warmth is needed. Containing a tenth of the water compared to a standard steel panel radiator, these products react at least three times faster to fluctuations in ambient temperature. This means that they heat up immediately if the temperature falls below the set level and stop emitting heat as soon as that same level is reached. This fast reaction time is essential in providing and maintaining comfort for residents. What’s more, low surface temperature (LST) radiators which incorporate Low-H2O technology are ideal for the care home environment

where safety is paramount. Products such as Jaga’s Maxi 2020, feature a strong, robust casing that has a low surface temperature, eliminating the chance of burns. This casing also has rounded corners and edges to minimise the risk of injury if anyone fell against the radiator.


As well as eliminating the risk of scalding, it is available in anti-bacterial and anti-ligature options for enhanced levels of hygiene and safety. Low-H2O radiators can be also coupled with fan assisted DBE (Dynamic Boost Effect) technology, which improves airflow and boosts heat output by drawing air over the element – increasing the efficiency of the radiator and helping to quietly circulate air around the room. This allows for smaller units with greater outputs to be installed when space, aesthetics or renewable technologies are being considered. Whilst the DBE unit maintains rapid, effective and accurate room comfort conditions, it can also supply a quick boost of heat if required.


As we approach winter, the financial pressures that come with increased energy usage are becoming all too real for facilities managers. But by taking steps to review current energy spend and by deploying new technology, efficiency savings can be achieved without compromising the comfort of residents.
