# Designing climate-compatible infrastructure

**More than ever, the climate emergency imposes that all new, or retrofitted, infrastructure minimises carbon emissions and is resilient to the changing climate and especially to extreme weather events. SYSTRA has developed tools to help decision-making in addressing these challenges. Sofia Fotiadou, the Group’s Sustainable Design Manager sheds light on the subject.**

Human induced global warming is changing our climate at a rate that is
unprecedented over millennia. Physical impacts of climate change, such as rising
temperatures, changing patterns of precipitation, increased intensity of extreme
weather events and sea level rise will increase vulnerability of all types of
infrastructure.

There is scientific consensus that avoiding catastrophic climate change requires
limiting average global temperature increase due to greenhouse gas emissions to
1.5˚C compared to preindustrial times. According to the Intergovernmental Panel
on Climate Change, temperature rise could be limited to 1.5˚C, only if the world
substantially reduces emissions in the 2020s and get to net-zero emissions by
around 2050.

More than ever, the climate emergency calls for infrastructure that is being
consistent with low-carbon transitions, as well as resilient to the changing
climate and especially to extreme weather events.

Designing, building, and operating climate-compatible infrastructure means that
lifecycle carbon emissions and climate vulnerability impacts are considered
** from the early stages of the design**. This requires using robust methods of
quantification that allows identification of hotspots to support informed
decision-making around solutions that mitigate, and adapt to, these climate
impacts.

## 󠀁**Low-carbon infrastructure**󠁿

Carbon emissions result throughout the lifecycle of an infrastructure, hence
designing a climate-compatible infrastructure needs us to take into
consideration and minimise carbon impacts linked to materials’ extraction and
production, their transport to the construction site, all construction site
activities, the operational phase, including maintenance, and finally, the
end-of-life and decommissioning of the infrastructure.

The lifetime of transport infrastructure extends to several decades, often more
than 100 years, yet the majority of lifecycle carbon emissions are “locked-in”
** during the design phase**; hence largely dependent on design decisions.
Clearly, it is of paramount importance that carbon is considered from the early
design stages and that designers have the information on the carbon impact of
the design solutions they are considering in real time with the design, so that
they can select and prioritise low-carbon solutions in compliance with the
carbon reduction objectives of the project.

**To address this challenge, we developed CARBONTRACKER**, a web application
that can help engineering teams integrate lifecycle carbon from the early design
stages and throughout the entire design and construction process of an
infrastructure. The application is BIM compatible and is specifically designed
for transport infrastructures (railway/tramway, highway, cable car system, etc)
including all related buildings (stations, depots, technical installations,
etc).

The tool helps us measure the carbon impact at different levels of granularity,
from the asset level to project level, identify carbon hotspots, run sensitivity
analysis, test alternative solutions and various design scenarios that can
reduce lifecycle carbon emissions, as well as assess progress towards project
carbon reduction targets. Most importantly, the entire process can take place
**in real time with the design** to help informed decision making and ensure the
design is considering the carbon impact along with other project requirements,
such as cost, durability, safety, technical performance, etc.

One of the main contributors to the development of this tool was Lucas Gibaud,
BIM and Data Engineer.

## 󠀁**Climate resilient infrastructure**󠁿

Infrastructure should be designed and constructed in a way that anticipates and
adapts to changing climate conditions. Taking as a reference historic trends and
past extremes weather conditions (flooding, heatwaves, etc.) might not be
sufficient for developing infrastructures with lifetimes that extend to several
decades ahead, as the ongoing climate change tends to continuously intensify
extreme weather events.

Moreover, intensive urbanisation and lack of urban planning in many metropolitan
cities of the world are creating microclimates, due to phenomena such as the
**urban heat island**, which are enhanced by global warming creating conditions
of discomfort for the people living and working in these areas, especially
during seasons with high ambient temperatures.

To better understand future climatic conditions and risks at the scale of a
transport infrastructure project, we developed
** a climate data visualization mapping tool,** **CLIMATEplus, **that makes
possible to identify the areas of vulnerability of our project area in terms of
the evolution of extreme episodes of heat, precipitation and winds, in the
short, medium and long term (up to 2100).

**CLIMATEplus uses climate data and projections of the Intergovernmental Panel on Climate Change (IPCC)**
, which are based on scenarios related to the different levels of concentration
of greenhouse gases resulting from human activity in the atmosphere. They
therefore represent the possible futures of the climate.

CLIMATEplus allows us to exploit regional climate projection databases from
multiple models by interpolating, over our project area, several climate
indicators to visualise their trend according to different greenhouse gas
emissions scenarios and thus assess the vulnerability of the infrastructure over
time.

We have integrated an additional function to the tool, in order to map
microclimates within urban areas, largely linked to the heat island effect. For
this function, **CLIMATEplus imports surface temperature from satellite data **
to provide maps that present the different levels of temperatures within urban
areas during summer days with high observed temperatures.

The long lifespan of infrastructure assets means that design and development
decisions made now will lock-in a certain amount of carbon emissions, as well as
climate vulnerability, if they do not consider these impacts from the onset of
their concept design. At SYSTRA we work closely with our discipline experts to
address these challenges and design infrastructures that contribute to the race
against climate change.
