CIUDAD Y TERRITORIO PRODUCTIVO

• Arup is an independent firm of designers, planners, engineers, consultants and technical specialists, working across every aspect of today’s built

environment.

• Arup employs more than 14,000 people, in more than 34 countries in a culture underpinned by Sir Ove Arup’s aims and values.

Arup provided

transaction advice on investments worth over

$19bn in 2017 alone.

• Energy.- Whether it’s advisory services, energy system

integration, or the detailed design of offshore energy structures,

• we work on behalf of clients across the world to shape transitional and long-term solutions; addressing a wide range of energy sectors

Energy as solution to city challenges.

Cities as solutions to Energy and climate challenges

• Cities – 55% population now , half of global energy consumption and 40% of greenhouse gas emissions

• 68% of the world population will live in urban areas by 2050, increasing to 70% by 2060.

• Reducing the impact of urbanization through

increasing urban energy efficiency and switching to clean, low carbon resources

• Critical for cities to continue to thrive as engines of economic growth and human creativity

• Distinct energy challenges, constraints and opportunities

• 1.- dense, mixed use urban forms can reduce the unit cost of transport and energy infrastructure but density can also lead to adverse effects urban heat island and reduce the availability of renewables

• 2.- dynamic challenges including rapid urbanization, demographic change and economic change…. struggle to keep up with the pace of growth, while others in

contracting economies struggle to remain viable while providing even basic services

• 3.- the legacies of existing urban form, buildings and infrastructure tend to “lock-in” energy consumption patterns and available sources and vectors of energy.

• 4.- governance of cities –critical to the design effective solutions for energy systems which also deliver other city drivers – such as air quality, economy and resilience.

Climate Emergency, Urban Opportunity, the 2019 flagship report from the Coalition for Urban Transitions, shows that it is possible to cut 90% of emissions from cities using currently available technologies and practices, and that compact,

connected and clean cities could generate a stream of returns worth nearly US$24 trillion by 2050. Low-carbon measures in cities could also support 87 million jobs by 2030 in sectors such as building efficiency and public transport.

European Union.- Energy Strategy

• “Secure, competitive, and sustainable energy”

2030 Energy Strategy

• Energy efficiency 27%,-30%

• Emissions GHG -40%

• Renewables 27%->32%

2050 Road Map:

• Reducing greenhouse gas emissions by 80-95%, when compared to 1990 levels, by 2050

• share of RES in electricity consumption aiming to reaching 97%.

• electricity will have to play a much greater role than now (almost doubling its share in final energy demand to 36-39% in 2050)
