It is through collaborative approaches like this between government and the private sector that we can achieve value-driven transformation of the sector and bring enormous benefit to the built environment and society more broadly.. On 8 July 2020, Chancellor Rishi Sunak committed funding to modern methods of construction in his Plan for Jobs..

It delivers a raft of benefits to the built environment and significant reductions in embodied and operational carbon..Embodied carbon calculations were undertaken by Cundall, on behalf of Landsec.

Cundall updated the calculations at every stage of design, from the Business as Usual (BaU) design in 2018, the incorporation of P-DfMA by Bryden Wood in 2019, through to completion in 2023.The BaU scheme was a traditionally designed office building with a steel frame and a concrete slab, a large basement beneath both buildings and gas fired heating system.In contrast, the built scheme used P-DfMA, worked to minimise the size of the basement and decarbonised the MEP services using heat pumps..

The results showed that the upfront carbon (the carbon used on day one to manufacture the materials, transport them to site, and to install them) was reduced by.between the BaU scheme and the as-built performance of the P-DfMA scheme.

This is a significant improvement which can be attributed to both the use of DfMA and the low carbon specification of materials..

Embodied carbon comparisons.Rapid grid decarbonisation and the use of high efficiency heat pumps results in extremely low carbon emissions and gives clients the option of going net zero in operation through the use of additional PV or green electricity tariffs.

When coupled with building mounted renewables, it can deliver low to non-existent energy bills to occupants, with some designs capable of being cost negative over the course of the year..Excellent Occupant Experience: Both Passivhaus and Bryden Wood believe that environmental performance should not come at the expense of occupant experience.

This is reflected in the designs targeting both the Passivhaus Thermal Comfort criterion as well as CIBSE TM 59, which ensures adequate thermal performance.. Resilient and adaptable to different climate conditions: Passivhaus also provides additional resilience by adopting a design based on passive design strategies coupled with technological solutions that can easily be upgraded, refurbished and replaced.Whilst Passivhaus was originally developed for residential buildings in Germany, the standard and its principles can be adopted in all kinds of building types, locations and climatic scenarios, and respond to the effects of global warming..
