Water is becoming more scarce at the same time as the population and demand for water is increasing. As a result, the need to develop practical and innovative ways to reduce water and energy use and lower greenhouse gas emissions is crucial to safeguard the future of our planet.
Showering accounts for around 25% of the water used in the home (EnergySavingsTrust). But it is not just about the amount of water, it’s also about the amount of energy required to heat the water. With the introduction of the Future Homes Standard in 2025 the energy requirements in Part L are being progressively ramped up to ensure that new build homes are future-proofed with low carbon heating, micro-generation devices and world-leading levels of energy efficiency. Reducing energy use, embodied carbon and water consumption remains high on the government’s agenda and is seen as a vital first step to ensure the construction industry can deliver the significant reductions necessary by 2030 in order to have a realistic prospect of achieving net zero carbon for the whole UK building stock by 2050.
Improvements in fabric efficiency will no doubt help future homes to save significant levels of energy, however, the demands of the householders remain unchanged. For example, in the case of a super-insulated dwelling Domestic Hot Water (DHW) requirements will be the same as a traditional-built dwelling e.g. similar number of occupants with the same water-use behaviour i.e. showering. This presents an interesting shift in household energy demand. As building efficiency improves so the percentage share of energy attributed to hot water will increase, making hot water generation in Future Homes the largest portion of the household energy budget.
There is urgent requirement to improve the efficiency of showers to not only reduce water, energy and carbon emissions but to manage and maintain household bills – especially considering 13.4% UK households live in fuel poverty according to the Department for Energy Security & Net Zero.
