In doing so, it delivers a raft of benefits to the built environment and, in particular through significant reductions in embodied and operational carbon, to society more broadly (the construction sector currently accounts for 38% of global carbon emissions)..
We need solutions not only for coal, but also for liquid fuels.Terra Praxis is focusing on the most significant of energy initiatives, including oil and gas.
Currently, 100 million barrels of oil are used per day, with more than half of our global energy predicted to still be coming from fossil fuels by mid-century.This reality would lead to a three to four degree trajectory of warming, and a very bad environmental outcome.. One potential decarbonisation solution Terra Praxis has been exploring is the possibility of very low-cost, large-scale hydrogen production.Hydrogen is difficult to store, transport and move around, so it isn’t particularly useful as an end product, as it would require a lot of new infrastructure for end users.
However, it does have strong potential as an ingredient in clean, drop-in, substitute fuels, such as ammonia (which can be used as a Marine shipping fuel), or synthetic hydrocarbons.Importantly, this would mean that existing storage, transport and end-use infrastructure could continue to be used, including the use of today's planes and ships, making these kinds of solutions extremely useful..
The sticking point is that in order for hydrogen to be used successfully as an ingredient in these alternative fuels, it needs to be very inexpensive, costing less than one dollar per kilogram.
This is significantly out of range for any of the prospects for renewables until 2050, largely because they are very dispersed, dilute energy sources.In this framework, the brief becomes a much more malleable concept.
It’s a starting point.It’s a way in which a client can express their perceived need.
Given that the brief charts the course for the remainder of the project it is critical that it is a well-articulated leading document.An architect’s inability to spend time developing the brief – and in many cases being cast as simply ‘another consultant’ rather than an enabler and driver of a process – means that the most critical part of a project might simply follow the flow of least resistance.
