Metro de Santiago has awarded a contract worth €77 million for the construction of the first sections of the new Line 3 of the Santiago de Chile Metro to a consortium headed by Acciona, also including Chilean companies Brotec and Icafal.

The contract includes construction of 6.7 km of tunnels and accesses to installations for the stations of Cola de Maniobras, Estación Terminal Norte, Estación Cardenal Caro, Vivaceta, Conchalí and Plaza Chacabuco.

The project's completion is planned for the end of next year and it will create over 1,600 jobs at times of peak activity, with an average of more than 900 people employed during the works.

Line 3 has a total length of 22 kilometers and crosses the historic center of the Chilean capital. It has 18 stations and will serve over 660,000 people.

Acciona said its experience and track record in building Metro networks and tunnels in complex environments, both from the engineering and the environmental and social points of view, has landed it the work.

The Spanish company has played a major role in the development of the Metro networks in Madrid, San Juan de Puerto Rico and Medellin. It is currently working on the construction of the first phase of the line 1 of the Quito Metro (Ecuador) and the East Line in Fortaleza (Brazil).

Major tunneling work it has carried out includes the underground routing of the M-30 ring motorway in Madrid and the Legacy Way tunnel in Australia, both located inside cities, the tunnel for the particle accelerator of the European Organization for Nuclear Research (CERN) between France and Switzerland and the high-speed train accesses in Bologna (Italy).

International Code Council focuses on energy efficiency

The International Code Council has released a new framework to assist governments and building industry stakeholders in meeting energy efficiency and greenhouse gas reduction goals.  

The Code Council Board of Directors, which consists of 18 government code officials who were elected by their peers, adopted the framework, Leading the Way to Energy Efficiency: A Path Forward on Energy and Sustainability to Confront a Changing Climate

This framework includes using the Code Council’s American National Standards Institute (ANSI) approved standards process to update the International Energy Conservation Code (IECC).  

Future editions of the IECC will build on prior successes including an increase of efficiency requirements by about 40%, or an average of 8% a cycle from 2006 to 2021, allowing the IECC to remain a strong avenue for communities to reach their energy efficiency and sustainability goals globally. 

With the base 2021 IECC efficiency requirements just 10% away from net zero for residential buildings, under the new framework future editions of the IECC will increase base efficiency using a balancing test proposed in bipartisan legislation that has cleared the US House and Senate and has been supported by energy efficiency advocates and the building industry

The IECC will be developed under a revised scope and be part of a portfolio of greenhouse gas reduction solutions that could address electric vehicles, electrification and decarbonization, integration of renewable energy and energy storage, existing buildings performance standards and more. 

The Code Council’s new framework will also provide optional requirements aimed at achieving net zero energy buildings presently and by 2030. Using a tiered approach, the framework offers adopting jurisdictions a menu of options, from a set of minimum requirements to pathways to net zero energy and additional greenhouse gas reduction policies.   

The Code Council has also announced the establishment of an Energy and Carbon Advisory Council which will consist of governmental and industry leaders to inform the Code Council’s efforts. 

The Energy and Carbon Advisory Council will advise on which additional greenhouse gas reduction policies the IECC should integrate, the pace that the IECC’s baseline efficiency requirements should advance, plus needs and gaps that the Code Council should work to address. The Code Council will begin outreach to fill the Energy and Carbon Advisory Council in March. 

Focus on climate and energy efficiency globally

The Use of Climate Data and Assessment of Extreme Weather Event Risks in Building Codes Around the World was published last month. 

Climate data is frequently only updated on a 10-year cycle on average, so as weather becomes more severe from year to year, the underlying data simply does not accurately reflect the risk to the building of these extreme weather-related events. International Codes are updated on a three-year cycle.

Climate change, coupled with net zero emission targets, is focusing minds to act faster.

From the end of this year, all new buildings in Singapore will face higher minimum energy performance requirements, according to the Building and Construction Authority (BCA). It will raise the minimum energy performance requirements for new buildings and existing buildings that undergo major retrofit, to be 50% and 40% more energy efficient respectively, compared with 2005 levels. The city state aims to 'green' 80% of buildings by 2030.

The Net Zero Home standard developed by CCG (Scotland) is intended to deliver a standard of specification that reduces greenhouse gas emissions arising from regulated operational energy use to a rate less than or equal to 0kg C02/m2/year. 

A new construction products national regulator is imminent in the UK, in a bid to bolster standards following the Grenfell inquiry.
