BRE Innovation Park in Watford to house the Nuhaus energy efficient, factory built house


Two semi-detached energy efficient houses are set to be built by Swiss housing innovators Nühaus GmbH on the BRE Innovation Park in Watford using the company’s ‘best value’ methodology, which aims to deliver affordable housing with low environmental impact.

The housing system features bespoke structural insulated panels that can achieve air tightness values of 3 m3/hr/m2@50Pa and can also attain CO2 emissions in the range of 15.21 kg CO2/m2 -12.03 kg CO2/m2. The fully rigid modular solution arrives on site fully painted, decorated, plumbed, wired and with kitchen, bathroom, windows and doors installed and fitted.

Other sustainability features of the development will include an air source heat pump, a Mechanical Heat-Recovery Ventilation (MHRV) system, sustainably sourced materials, as well as 100% recycling of wastage during construction.

MD of Nühaus Stephen McCready said “The Nühaus system provides affordable homes delivering affordable warmth, no oil no gas. We build our super energy efficient houses in a factory, so you don’t have to build them in the rain anymore, all our houses are Code Level 4 as standard, and can be upgraded to 5 or 6 if required’.

Global Development Director at BRE Nick Smith said ’There are currently 4.5 million people on housing waiting lists in the UK. Affordable sustainable housing solutions like Nühaus, have great potential in the marketplace. We are pleased to host the housing system on the park where housing providers, developers and other visitors can experience it firsthand’.

It’s also important to mention that such an energy-efficient house could be further improved by implementing an advanced house and home energy management system, and this is specifically where HeatingSave could put its extensive experience to work.

The system is built around the idea of optimizing the energy consumption levels within any area with the help of an advanced heat-loss algorithm that creates a specific profile for any building and based on that, switches heating on later if its warm and off earlier if its cold.

Additionally, the automatic occupancy detection allows the temperature to reduce to a background when areas are not used and quickly brought up to temperature when they are being used.

Furthermore, given the fact that it employs a variety of temperature, air quality and occupancy, sensors, the system can also be used for thoroughly monitoring energy expenditure around any building.
