In this context, the request for Whole Life Carbon Assessment (WLCA) has increased notably over the last few years.
It would be impossible to review and approve the design to ensure the required quality for these types of highly regulated buildings.It would be impossible to get the required supply chain capacity for the required design, manufacture, and construction capabilities.. What we need is a fundamental rethink with regards to the future of coal and how nuclear facilities are conceived, designed, procured, and delivered.
Instead of approaching this task as thousands of individual refurbishments, we need to have a unified approach where the design is simplified and standardised in such a way that a much wider range of designers, manufacturers and contractors can participate, and the design knowledge is embedded in building systems and design tools so that everyone involved can benefit from the learning on all the other projects.. To achieve this, we are working with Terra Praxis and their wider team, including specialists from MIT, University at Buffalo, Microsoft and KPMG, to:.Reduce, rationalise, standardise and optimise the building and engineering systems that are needed for a refurbished plant, in order to.Reduce, rationalise, standardise and optimise the design, approval, manufacture, assembly and operation processes, in order to.
Reduce, rationalise, standardise and optimise the interactions between the required different supply chain organisations, to realise the processes described above at the scale that is required.. Terra Praxis are creating a business model that uses technology to connect people, organisations, and resources in an interactive ecosystem in which value can be created and exchanged.To realise this ecosystem, Bryden Wood is involved in developing a technological infrastructure that provides tools and services that make it easy for customers and suppliers to interact to realise the required refurbishments.. To make that possible, Bryden Wood also need to create an engineering platform solution: a building system that can deliver the required variety of solutions for differing requirements in different situations, but that is rationalised, standardised and optimised appropriately to enable the required simplification of all processes that make it possible for the supply chain to collaboratively deliver this built solution.. New nuclear: system simplification and standardisation with P-DfMA.
Existing coal plants vary widely.
There are very different site layouts and different levels of site conditions.Achieving net zero operational and embodied carbon with lean design and modern methods of construction.
Bryden Wood’s strategy to achieve net zero carbon building is based on the adoption of a clear hierarchy for operational and embodied carbon..In order to substantially reduce operational carbon, our designs will adopt the following hierarchy:.
Be Lean (passive): minimise the use of energy via passive design measures such as optimised form, orientation and window-to-wall ratio (WWR); design energy efficient facades that incorporate thermal insulation, high airtightness, external shading and solar control glazing; use of natural ventilation and thermal mass and design transitional spaces and low thermal expectation spaces.. Be Lean (active): minimise the use of energy via energy efficient lighting (LED, daylight and presence control sensors) and ventilation systems (demand control ventilation, low SFPs, heat recovery); use technologies such as waste-water heat recovery and specify energy efficient lifts and appliances/equipment.. Be Clean: connect to district heating networks that have plans for decarbonisation; explore plans and feasibility of local hydrogen district networks.. Be Green: use onsite low and zero carbon technologies such as air source heat pumps (ASHP), ground source heat pumps (GSHP), photovoltaic panels, solar collectors for domestic hot water and wind generation among others.. Be Smart: implement innovative technologies such as electric batteries, heat storage, post-occupancy evaluation and develop smart-metering systems..Offset: any remaining carbon should be offset via Power Purchase Agreements (PPA) or recognised carbon offset schemes.
