Following the inclusion of our Air-Powered showers within SAP Appendix Q, Kelda have again been featured by a leading UK housebuilding publication – this time Show House Magazine in their August edition.
With a readership of over 10,000 decision makers, Show House Magazine is where the housebuilding community meets. Show House Magazine is a leading publication for the UK housebuilding industry, offering in-depth coverage of the latest trends, news, and developments. The magazine serves as a key resource for professionals in the field, providing insights into topics like planning, architecture, and sustainability.
The feature specifically focuses on the process we embarked on to receive SAP recognition. The process included forming partnerships with leading national housebuilders, such as Barratt Developments, Vistry and Cala, who provided Kelda with homes to install our showers.
“We had to monitor the shower behaviour and usage for a period of time and then, independently and qualitatively, record the feedback of householders, to ensure that, one, the experience was great or acceptable, and two, that they weren’t showering for less time. So, what we’ve actually demonstrated was that we’ve got an overall score of about 8.3 out of 10 in terms of overall satisfaction; and then we’re using about four and a half litres of water per minute, rather than a conventional shower using 10 – we’re seeing a 55% reduction in water consumption” – Paul Ravnbo West, Marketing Director.
Test calculations have found that replacing a conventional mixer shower with our Air-Powered shower can help achieve compliance with Part L of the Building Regulations and, as less water is used, it can also help with Part G.
Test Calculations
Part L
- Reduced DER and DPER by up to 10 percentage points.
- Achieved minimum emissions and primary energy targets with up to 2 PV panels fewer.
And, when connected to WWHRS (System A):
- Reduced DER and DPER by up to 27 percentage points.
- Improved SAP score by up to 2 points.
- Achieved minimum emissions and primary energy targets with up to 4 PV panels fewer.
Part G
- Can help reduce the dwelling consumption of potable water to 105 LPPPD as required in Building Regulations in 2025 (using the fittings-based approach). In fact, along with other efficient water fittings it is possible to reduce water use to 75 LPPPD.
- Can help qualify for a water efficiency discount of up to £280 per plot (applied to infrastructure charges by water and wastewater companies). Please find further information here: https://www.ofwat.gov.uk/environmental-incentives-to-support-more-water-efficient-new-homes/.
