The first prison to adopt these design principles is the 1,680 place prison, HMP Five Wells, on the site of the former HMP Wellingborough, due for completion in 2021..
When considering how design choices impact embodied carbon, the data only supports the upfront carbon due to incomplete data for whole life carbon (WLC) for the BaU scheme (in 2018 the industry wasn’t regularly considering WLC calculations for projects)..The key findings:.
The substructure used 50% cement replacement, used recycled aggregates from the demolition on site and procured the concrete locally.In addition, the basement volume was reduced which minimised the excavation and material usage resulting in a combined 46% improvement compared with the Business as Usual scheme..The P-DfMA approach significantly reduced embodied carbon of the superstructure.
This is due to the reduction in steel weight.Once the concrete mix was taken into account, the use of 40% GGBS and local procurement, and 26% recycled content of steel the savings are circa 60%..
The embodied carbon within the façade increased compared with initial projections.
This is partly due to the anodized finish of the aluminium frame curtain walling (this couldn’t be altered due to the extant planning permission) and partly because the façade was manufactured in Poland – a country with both many transport miles and an electricity grid predominantly fuelled by coal..Maintaining the client lab equipment list with all the necessary services is a must.
As the information becomes more detailed, the list should be updated to reflect the latest information.Most issues we come across on a project are due to missing services or undefined duties within the laboratory equipment list.. Labs without extracting equipment can follow the Chartered Institution of Building Services Engineers (CIBSE) guidance for air change rates, with supplementary cooling required from internal units such as fan coil units.
For spaces requiring close temperature control, we do not use refrigerant-to- air cooling..In labs with extracting equipment, especially fume cupboards, the make-up air required may be a very high volume and allow for centralised air cooling.
