If our objective is to replace enough dirty energy with clean energy in time for us to decarbonise and avert the worst consequences of global warming, we need to close down as many dirty energy sources as possible and replace them with clean energy sources.
Maswiken comments upon the ample sizes of the recovery spaces.He, Highton and Goel remark upon the particular spaciousness of the theatres, with Goel commenting that this is a ‘major attraction’ of Circle and highlighting the fact that the anesthetic rooms are also very spacious.. ‘This facility had a particularly large percentage of orthopedic surgeons,’ says Wood, ‘and orthopedic surgeons needed a very particular form of operating theatre...more instruments tend to be involved in the operations.
Therefore, we actually simulated in three dimensions, in a virtual environment, how they were going to use their equipment...we were able to position the components within the operating theatre more accurately, so that the efficiency of the operations could be greater than within a typical, general purpose operating theatre.’.The high ceilings in the theatres are mentioned by Maswiken, as being a particularly excellent feature of the building, with respect to the way they aid with the use and management of equipment.‘You can actually leave the key equipment in those theatres, rather than moving that equipment up and down all the time,’ he says, before reflecting that actually, because the theatres benefit from ‘integrated systems,’ everything is already mounted and can just be moved around, which he refers to as, ‘yet another advantage.’.
Johnston elaborates, commenting on the high level of integration between the structural, MEP, architectural finishes, electrical, data etc… All of this, he says, allowed Bryden Wood ‘to create a high level of prefabricated MEP (building in ease of maintenance and replacement) interfacing with a highly systemised superstructure.’.In addition to these advantages, Maswiken enthuses about how lucky they are at Circle Reading to have their core/prep rooms, as well as the benefit of a layout which enables patients to go out through recovery to the wards, rather than back through the theatres.. Goel also comments on layout efficiency saying, ‘The recovery, the day case ward...is very close by.. Further to this, he and Maswiken have many other positive elements to highlight about the Circle theatres.
The three used predominantly for orthopaedic surgery have laminate floors and special ventilation systems providing ultra clean air, which Goel describes as ‘perfect.’ He also enthuses about how having images of x-rays on the computer system, enables them to be projected onto a television screen on the wall.
On a more personal note, he enjoys the ability to put music on.In many cases, they refer to the possibility of achieving net zero carbon in operation only, which means that they do not account for the embodied carbon of the building over its lifecycle.
A net zero carbon building is one that achieves both zero operational (regulated and unregulated) and zero embodied emissions.. Buildings should only be considered net zero carbon if the amount of carbon emissions associated with a building’s products/materials, construction stages, use (including operation) and deconstruction, is zero or negative.This can be achieved via measures to reduce the use or the carbon of individual materials, the implementation of energy efficiency measures, the use of on-site renewables and finally a combination of carbon offset schemes and green Power Purchase Agreements (PPA)..
It should be noted, that for most new developments nowadays it is not feasible to become net zero within the possibilities of the design (energy and material efficiency measures), so the use of carbon offset schemes and PPA is essential.. Why should we focus on sustainable construction and net zero carbon?.The UK has established ambitious targets to reduce carbon by 2050.
