We have also built an incubator/accelerator project; a lab building for startups.
Adding a MVHR and ductwork would increase carbon by 6.5 kgCO2/m2.Adding a heat pump would increase carbon by 3.5 kgCO2/m2.
Adding insultation (rockwool) thickness in walls from 150mm to 250mm of rockwool would increase carbon by 3.6 kgCO2/m2.Adding insultation (rockwool) thickness in floor and ceiling from 190mm to 370mm of rockwool would increase carbon by 6 kgCO2/m2.Reducing the boiler size from a 15kw electric boiler to a 3kw boiler would reduce carbon by 1.69 kgCO2/m2.
Reducing the number of radiators from 10 to just one would reduce carbon by 10.7 kgCO2/m2.Reducing the size of the photovoltaic array from 24 to 12 units would reduce carbon by 12 kgCO2/m2.
All the above items added up together would mean just a reduction of around 4.7 kgCO2/m2, mainly due to the simplification of the heating and photovoltaic systems.
Compared to a residential LETI 2020 (Band C) target building (A-C) with a total embodied carbon of 675 kgCO2/m2, that is equivalent to just 0.7% reduction in carbon..Reduction of the time and human resources spent in the delivery of the project.
Enables local sourcing.Reduction in whole life carbon.
This has led to a 22% reduction in embodied carbon compared to the traditional construction approach.The project predicts a 9.5% reduction in capital cost and 13% reduction in programme..
