Sustainable buildings: passivhaus, low carbon design and NABERS | Pablo Gugel, Director of Sustainability
The data structures that we build around Chips allow data to be aggregated between different levels.. We can associate any type of data with a Chip.
The UK aspires to reduce total carbon emissions by 78% by 2035, compared to 2020 levels, and become net zero carbon by 2050.These ambitions, translated to the built environment, can only be achieved via the implementation of measures to reduce operational and embodied carbon of new buildings, upgrading existing buildings, the use of ambitious policies and crucially via a decarbonised grid..
The built environment contributes to around 40% of the UK's total carbon footprint.Based on UKGBC’s Net Zero Carbon Buildings “A framework definition", a typical Cat A office’s building embodied carbon, after the first year of use, would be 75% of the total carbon, whilst the operational carbon would be around 25%.Although the operational carbon will accumulate overtime, a decarbonised grid will mean that the growth rate will flatten, and after 60 years the embodied carbon will still remain higher than operational carbon, as shown in Figure 2.
This means that the focus and the priority should shift from operational to embodied carbon during the design..Embodied and operational carbon increase in a decarbonised grid scenario.
In this context, the request for Whole Life Carbon Assessment (WLCA) has increased notably over the last few years.
The production of WLCA is required by BREEAM and the GLA.With just a single gateway, it’s possible to achieve five or ten kilometers of distance, picking up gate sensors and various pieces of important information.
This might include things such as whether someone is walking in an area they shouldn’t be, or even checking to see whether a structure may have moved over a three- or six-month period.This is the type of information that’s truly valuable onsite, and we should be interrogating it.
However, it’s important to keep in mind the temporary nature of construction sites.Once they’ve gone, we’ve lost the opportunity to use construction technology to gather that simple, valuable information that can tell us what’s really happening.
