R-gen’s latest innovation is to create Zero Carbon homes from slab to final completion within 5 weeks on site. Over 70% of the building is constructed in the factory, and is completed to the PassivHaus Air tight standard within 48 hours of erection.
R-gen is able to produce an extreme fabric first Off Site Manufactured PassivHaus certified home that exceeds the Fabric Performance and Carbon Compliance targets specified within the Allowable Solutions Policy. The homes are timber framed using sustainable resources and are factory built in the UK.
This exciting development is ahead of Government commitments on zero carbon. The UK Government is committed to reducing CO2 emissions levels by at least 80% by 2050 from the 1990 level. The Climate Change Act of 2008 set out a number of clear targets of how this may be implemented, one of which is that by 2016 all new homes should demonstrate that the construction and energy performance should have zero impact on carbon emissions.
This is a move away from the traditional definition of zero carbon, which sets out that any home should produce more energy from non-carbon sources than it actually needs to consume in a year from carbon fuels.
The Zero Carbon Hub has set out a mechanism of how this may be achieved through its Allowable Solutions strategy. Essentially, the Policy is aligned with the European guidelines detailed in the Energy Performance of Buildings Directive, and is based on the principles that new homes should meet a fabric performance standard measured in the energy needed to provide heating and ventilation, and a Carbon Compliance limit calculated on the volume of carbon emissions remaining after taking into consideration heating, cooling, fixed lighting and ventilation. Any remaining Co2 emissions may be off- set by a capital contribution to specific carbon saving funds.
