Green buildings: better cities INTELI has been promoting the concept of smart city as a new urban paradigm, which is based on the use of information and communication technologies (ICT) to promote economic competitiveness, environmental sustainability and the quality of life of citizens. In addition to the development and application of the Smart Cities Index to the cities that make up the RENER Living Lab Network for Urban Innovation, with a view to measuring the level of urban intelligence of municipalities and promote the improvement of the performance of the territories, INTELI recently launched the Smart Cities Portugal platform. The objective of the network is to assert Portugal as a provider of technologies, products and services of a high added value for smart cities at a worldwide level, as well as a space for experimenting and testing innovative solutions in a real context. It aims to bring together the main agents of the value chain of the industry supplying solutions for smart cities, such as competitiveness centres and clusters, companies, business associations, entrepreneurs, universities and research centres, local governments, public bodies and users, in a logic of open innovation. The internationalisation of innovative urban solutions developed with Portuguese technology and the participation in European programmes of the next 2014-2020 framework are ambitions of the initiative, which intends to also intervene in terms of demand by contributing to the alleviation of market barriers in areas such as regulation, standardisation, public procurement and user involvement, etc. The buildings component is one of the strategic areas of the Smart Cities platform, together with energy, mobility, water and waste management, governance, security and quality of life. It is a privileged sphere of intervention, since the construction sector is responsible for a third of the global greenhouse gas emissions and for 40% of final energy consumption in Europe. It is within this framework that INTELI finds itself developing projects and working with local governments and communities in the promotion of green construction and rehabilitation. The Re-green – Regional Policies towards Green Buildings (INTERREG IVC) project is one of the examples of this strategy, and is being implemented in partnership with cities, regions and development agencies in 10 European countries. This edition of Cities.brief focuses on green buildings, presenting opinions, reports, case studies, facts, news and events on the theme, with a view to promoting the reflection and debate on the green urban economy on the path towards more innovative, sustainable and inclusive cities.

Green buildings, a trend or a reality?
In the last few years, the concept of ‘green economy’ has invaded the international and European political discourse (OECD, UN, and EC) However, the transition to a ‘green economy’ requires the creation of favourable conditions and of new political instruments conducive to green growth. The construction sector plays a fundamental role in this process since it is responsible for a third of the global greenhouse gas emissions and for 40% of final energy consumption in Europe (BPIE, 2011). It is also responsible for a third of the consumption of humanity’s resources, including 12% of all fresh water use, and for the production of about 40% of solid waste (UNEP, 2011). The emerging movement on green construction arose in the aftermath - during the last 40 years of the major energy crises that played an important role in the construction sector, acting as agents of change and of awareness in promoting energy efficiency technologies and more sustainable construction systems. As a result, concepts such as green,
sustainable and passive building, among others, proliferate, seeking equilibrium between economic factors and the commitments to the environment and society. According to the International Energy Agency (Laustsen, 2008), “green buildings are characterised as increasing energy efficiency, reducing water and materials consumption and improving health and the environment”. In this sense, the adoption of strategies focused on green buildings enables inducing a series of economic, environmental and social impacts. The social dimension has an impact on the level of comfort and health of the building’s occupants, in terms of productivity, well-being, air quality and good levels of natural lighting. From an economic viewpoint, the impact involves the mitigation of climate change, the creation of jobs - green jobs and the improvement of green products and services, among others.

Value added The Business Case for Green Buildings report (2013) identifies a set of benefits of green construction, according to five different areas: project and construction costs; asset value; operating costs; productivity and health in the workplace; risk mitigation. Project and construction costs: green construction does not necessarily have to cost more, particularly when the cost of the strategies, the environmental strategies and the coordination of the programme are integrated from the beginning of the process. Although green construction can mean a higher cost in comparison to conventional construction, the difference is not as high as is commonly perceived. Asset value: it is true that investors and society itself are increasingly informed about the environmental and social impacts of construction. In this regard, buildings with better environmental performances may benefit from increasingly faster liquidity in the market. For this reason, green buildings are capable of attracting tenants more easily, and also lead the rental and sales market in spite of higher prices. Operating costs: are based on the idea that green buildings have the capacity to save on expenses through the reduction of energy consumption, of water usage and also due to less need for long-term operations and maintenance expenses. The report also highlights that for green buildings to achieve a good performance they need to have effective management and there needs to be good collaboration between owners and tenants. Productivity and health in the workplace: refers to how the attributes of green buildings, namely in terms of indoor environment, can improve the productivity of its workers and occupants, as well as contribute to their health and well-being. Risk mitigation: is based on the risk factors of sustainability that can significantly affect the rent and the future value of the immovable assets, which will in turn affect the return on investment. Regulatory risks are becoming increasingly evident in countries and cities throughout the world, including laws that forbid inefficient buildings, the promotion or mandatory nature of compliance with specific construction codes and mandatory disclosure. Extreme climate situations and systemic changes in weather patterns also affect the security of buildings.

Investment in green rehabilitation The current renovation/rehabilitation rate of buildings is too low. In developed countries, the huge opportunity to make the construction sector green depends mainly on the re-adaptation of existing buildings (UNEP, 2011). Europe’s Buildings under the Microscope report (BPIE, 2011) reinforces this idea, demonstrating that whilst new buildings can be built with high performance levels, the older buildings represent the major proportion of the European building stock, which is where the greatest potential to improve energy performance levels lies. In terms of numbers, the same report shows that a significant part of the building stock in Europe is more than 50 years old and many that are in use are hundreds of years old, giving as example the case of the residential buildings in which about 40% were built before 1960. In this context, green rehabilitation represents a priority investment supported by EU initiatives within the scope of energy and climate change. It is important to mention the European movement – Renovate Europe Campaign, initiated in 2011 by EuroACE (The European Alliance of Companies for Energy Efficiency in Buildings) which was composed with the objective of guaranteeing an ambitious renovation rate of the building stock from the current 1% to 3% in 2010 and to also guarantee that the aggregate result of those renovations results in a reduction of about 80% in energy demand from the building stock in 2015 relative to 2005.
The emergence of new policies Throughout the world, policies related to green buildings are identified; however, in the majority of cases, there are more government incentive programmes relative to specific aspects of green buildings, such as energy efficiency measures, water efficiency measures, certification of buildings, etc., than those that approach green construction as a whole. According to the McGraw-Hill Construction Research & Analytics Green Building Trends report (2013) the policies focused on energy efficiency measures are the most commonly adopted internationally in relation to green buildings. Throughout the world, different approaches to green construction have emerged. The same report
concludes that in some countries, such as Canada and the USA, the government was the driver, defining policies focused on green buildings that strongly influenced the market. However, the same did not happen in other cases such as Brazil and Chile where the movement was initiated by private property owners, acting as drivers of growth of green buildings and, together with companies, want the support and incentive of governments. This relationship between the market and government is important for policies to be more effective and suited to different contexts. The importance of the local and regional authorities is fundamental in this process, since they are the closest and most agile level of government relative to the needs of citizens. Local governments have a strong influence in various areas directly related to green buildings and green economy, such as: provision of urban services, regulation of construction codes and of soil use, etc. According to ICLEI (2011): “local governments are the strongest

2nd Green Building Masterplan - Singapore The government of Singapore took the initiative of promoting environmental sustainability in buildings in 2005 with the launch of the BCA Green Mark Scheme. The green building certification and classification system was developed and managed by the Building Construction Authority (BCA), and constitutes the basis of the work of the first Green Building Masterplan of Singapore presented in 2006. Following on from the national sustainability strategies, the BCA launched the second Green Building Masterplan (www.bca.gov.sg/GreenMark/others/ gbmp2.pdf), in 2009, a roadmap defining the main initiatives to reach a truly sustainable construction environment in Singapore in 2030. The masterplan, of a holistic approach, involves several interesting initiatives, which include the promotion of R&D in green buildings, as well as pilot projects, the development of executive and academic training programmes and special programmes to improve the skills of experts in this field.
allies of national governments and of the United Nations in the creation of conditions for a sustainable human civilization on earth�. The Green Building Council (2011) also considers that: “local and regional governments are in a unique and, oftentimes, advantageous position to implement green building and urban design policies that will influence the approaches towards sustainability in the construction sector�.
Green public buildings - leading by example Within this framework, governments may act as drivers of the development of the green economy leading by example. Taking into account that public buildings represent, in terms of area, about 12% of the real estate stock of the EU (UNEP, 2011), buildings such as: schools, hospitals, social housing buildings, museums, etc., are ideal examples to initiate the implementation of green construction policies, as well as test them, boosting the actual market.

To sum up, a building by building approach based on the green construction concept contributes strongly towards making districts, communities and even cities greener!

Good for the globe, good for the business INTERVIEW
Staffan Haglind Green Business Officer of Skanska
Sweden-based Skanska is a leading global construction and development company committed to green in both its products and processes. Here, the company’s Green Business Officer, Staffan Haglind, explains why green is good business.
10
In recent years, several concepts have emerged related to sustainable construction, such as: net zero energy buildings (NZEB), plus energy buildings, passive buildings, green buildings, etc. Why has Skanska adopted green buildings as its flagship concept? For us “Green buildings” have a wider definition. Most concepts focus on energy, while we view green from a wider perspective that also includes carbon, material and water. Moreover, sustainable buildings must also take social factors into account. Therefore, we also focus on social benefits like increased productivity, healthier workplaces and lower sickleave. And of course a sustainable building must also target our zero visions for workplace accidents and ethical breaches.
“
The key to success is to put green on the agenda and set our green targets from day one of the planning process. Skanska as a multinational project developer has a practical notion of the construction costs. Do green buildings necessarily cost more than the traditional approaches? What is the difference between them in percentage terms? The key to success is to put green on the agenda and set our green targets from day one of the planning process, team up with skilled partners and avoid expensive and fancy green gadgets late in the process. If managed this way, green building doesn’t necessarily have to cost more. As many green buildings are not planned and executed that way, a price premium is common. It’s hard to mention a certain effect on price as it depends on market, design and level of greenness. What we do know, however, is that people tend to drastically overestimate the cost premium. Such preconception is a barrier to green building that we work hard to overcome. What about refurbishment processes in the green buildings context? In Skanska projects, do you work more with new green buildings or with refurbishment of existing ones?
We have many success stories in both categories. While new construction is usually considered fancier and achieves more media attention, the potential market for refurbishment is enormous and the absolute key to decreasing energy use in our built environment. After all, the vast majority of all buildings are old and underperforming. A limited investment, like the one we undertook for the green refurbishment (LEED Platinum Commercial Interior) of our U.S. office in Empire State Building in New York pays off, both financially and environmentally. The Return on Investment for green building is usually very attractive for both refurbishment and new construction.
“
We spend much time explaining to our clients and partners how they benefit from green building and how they can include this in their business cases instead of sub-optimizing by focusing on initial cost only
Regarding regulatory frameworks, how do you see the support of the central governments as well as regional and local authorities for promoting green buildings? Do you think that they can help to drive the adoption of green buildings? They can definitely be drivers in this field. We see this happening on the U.S. West Coast and UK, for example. But the situation varies a lot in different markets. Some markets are mainly driven by market forces, others are driven by regulations and taxes while yet others are driven by progressive municipalities. If all good forces join and act together, green building will grow even more rapidly. This would really have an impact on such global challenges as climate change and water scarcity. Do you think that the Green Building Councils around the world have an important role to play in the countries where they are based? Why?
11
GBCs are important forums for many reasons. They are committed drivers of green building and push development forward. The GBCs are excellent for networking and sharing the latest research findings, such as the World Green Building Council’s global report “The Business Case for Green Building” launched earlier this year. They market certification systems that allow buildings and areas to benchmark nationally and internationally. GBC seminars, training sessions etc. increase awareness, knowledge and competence. Skanska has been instrumental in establishing GBCs in many countries because we strongly believe they can make significant difference.
“
The key to success in all countries is to make the industry complement the question “How much extra does it cost?” with the question “How much value does it add?”
Concerning the professionals (architects, construction workers, etc.), the building’s owners and tenants, in your experience, are they aware of the importance of green buildings and open to the specificities of green building approaches? We see a wide spectrum. From those who are really committed, skilled, experienced and have good knowledge of the benefits of green building to others who don’t know and don’t care. We spend much time explaining to our clients and partners how they benefit from green building and how they can include this in their business cases instead of suboptimizing by focusing on initial cost only. In your opinion, how can we promote green building projects in countries that are living in a crisis framework, where the building sector is in deep decline? Is this an opportunity for green buildings?
12
This is a great opportunity where green jobs can be created at the same time as we unlock major business opportunities. The key to success in all countries is to make the industry complement the question “How much extra does it cost?” with the question “How much value does it add?”

Captions New Karolinska Solna PPP Hospital New Karolinska Solna (NKS) is the state-of-the-art university hospital currently under construction in Solna, Sweden. NKS is being designed and built for The Stockholm County Council to meet the demands of the future. It is Skanska’s largest project ever and also aiming to be the greenest hospital - the first PPP hospital to achieve LEED Gold certification thanks carefully sourced materials and Skanska’s patented geothermal system Deep Green Cooling.
Kjørbo The Powerhouse Alliance (a collaboration between Skanska, the architect firm Snøhetta, the environmental organization ZERO, the aluminum company Hydro, and the property management firm Entra Eiendom) has determined to go for energypositive buildings. Their first project - the refurbishment of Kjørbo office building in Sandvika, Norway - will be one of the greenest projects in Norway. After the retrofit, the office building will produce more energy than it uses. It is aiming for BREEAMNOR Outstanding.
M25 Widening project Carbon footprint played a vital role in indentifying carbon savings throughout the project and helped reduce emissions by 27 percent on the London M25 – one of the world’s longest and busiest ring roads. Together with recycling and innovative solutions it was possible to reduce the use of asphalt, excavation materials and demolition waste – and cut millions on the price!

INTELI presents contributions towards a greener Europe
In June, INTELI submitted two position papers with contributions in the areas of energy and sustainable construction policies, within the scope of the public consultation of the European Commission on the Green Paper - a framework for climate and energy policies in 2030. The Green Paper, proposed for discussion by the European Commission to the Member States, sets out a number of challenges, relevant for the assessment of the goals foreseen for the 2020 period, but mainly to correct errors and guarantee a coherent and sustainable path in the longer term (2030). Reflecting upon the new political framework for climate and for energy requires a diagnosis of the strides taken since the first 2008/2009 framework. The evolution observed in the last decade is remarkable, namely the achievement of the targets for 2020, the creation of the internal energy market and the development of new technological solutions. However, the volatility of markets, the consequences of the current economic crisis, the budgetary problems of Member States and of companies that have difficulty in mobilising funds for long-term investment and the position of the public opinion at a worldwide level, increasingly aware of the quality/ price relationship in renewable energies, are factors that the European Commission considers as determinant for a reflection in the medium-term. In reality, the EC wants to fight uncertainties of the economic cycle with a framework of definition of policies that reinforces confidence and promotes long-term investment plans. This is a relevant concern considering that the infrastructures needed for achieving the targets require considerable investment and have a life cycle of many years. Reinforce the paradigm, give confidence to investors and reduce uncertainty constitute objectives to be reached under the Green Paper.
More knowledge, better future INTELI, as coordinator of the European project RE-GREEN – Regional Policies Towards Green Regions and knowledge partner of RENERGY – Regional Strategies for Energy Conscious Communities, both supported by the INTERREG IVC programme of the EC, has an integrated vision of the Green Economy which combines strategic vectors in the energy and sustainable construction sectors, according to the most advanced concept of smart cities (competitive, sustainable, inclusive). RE-GREEN is a European project aimed at promoting the development of green regions, encouraging the implementation of construction policies oriented towards the reinforcement of energy efficiency and the use of renewable energies. RENERGY is a European territorial cooperation project which aims to contribute to the achievement of the objectives of the Energy Strategy 2020, concerning the reinforcement of the share of renewable energies in final energy consumption and the increase of energy efficiency in all economic sectors. The two projects are complementary if we consider them as links in a chain of policies aimed at reversing the negative impact of climate change.
Policies must increasingly focus on the concept of “green buildings” and “green rehabilitation”, involving a more simplified and flexible approach. The document also suggests the creation of new monitoring instruments of the building stock, as well as the creation of new funding lines to support green construction and rehabilitation. The exchange of experiences has reinforced knowledge about positive impacts. In this context, the role of public policies is equally important, as is its exemplary application in the building heritage of the public administration. All recommendations coincide with the need of the State to assume the role of leader in what is emerging as a New Economic Order, the Green Economy.
Both promote the exchange of experiences between European partners and the identification of best practices, with the objective of creating a knowledge framework capable of contributing, in the case of RE-GREEN, to the adoption of public policies oriented towards the improvement of energy efficiency and the use of renewable energies in the construction sector, as a means of contributing to the development of green regions. With respect to RENERGY, the main focus is on the importance of regulation and the creation of financial instruments aimed at extending the renewable energies market. In a moment of crisis in the eurozone, exacerbated by the crash in construction markets, the new economic paradigm usually referred to as Green Economy arises as a unique opportunity to promote growth, create jobs and contribute to the development of competitive and inclusive cities. The partners of RE-GREEN underline the importance of the creation of new markets associated to the rehabilitation of buildings in city centres, as the springboard for a new phase of economic growth. The change of the building stock, incorporating solutions that promote energy efficiency and the adoption whenever possible of clean energies, will enable a positive change in the quality of life of European cities. These solutions are not limited to buildings. They require a more comprehensive insight within the context of a district and its surrounding environment.

the future
with Smart Cities Portugal Smart network comprises companies, cities and knowledge
INTELI (Intelligence in Innovation), the PCTE (Competitiveness and Technology Pole for Energy) Association, CEIIA (managing body of the Competitiveness and Technology Pole for Mobility Industries), TICE.PT (Competitiveness Pole for Information Technologies, Communication and Electronics) and the Platform for Sustainable Construction Association (Sustainable Habitat Cluster) signed on 1 July a protocol for the creation of the SMART CITIES PORTUGAL network.
Mario Campolargo (DG CONNECT) participated as keynote speaker with a presentation on the theme “Smart Cities in the Europe 2020 Strategy”. SMART CITIES PORTUGAL keeps up with the most recent trends. Several countries and cities have created similar dynamics, as in the case of Malaga which in January 2013 launched a Corporate Innovation Platform for Smart Cities, composed of various bodies, within the scope of its participation in the Spanish Network of Smart Cities.
This event, chaired by the Secretary of State for Entrepreneurship, Competitiveness and Innovation, promoted the RENER cities network, coordinated by INTELI, at a strategic moment for the promotion abroad of what best is done in Portugal. The creation of an integrated platform of companies of excellence in vital areas such as energy, sustainable construction, information and communication technologies and mobility, contributes towards increasing the scale and competitiveness of the territories. But it also exponentially increases the entry of domestic companies into new markets. The creation of SMART CITIES PORTUGAL is of major importance considering the industries growth and associated services to smart and sustainable cities at a global level, which represents a significant potential for Portuguese companies that develop and produce innovative solutions for smart cities.
Together we do more The creation of integrated and multidisciplinary solutions that generate added value has benefits in both domestic and foreign markets, particularly in the strategic context of the next financial programming framework of the European Union (2014/2020).
In Portugal the work developed by companies has been remarkable, as an assessment of the activity of Centres and Associations that make up this smart partnership would reveal. INTELI assumes the role of coordinating body of Smart Cities Portugal, connected with local governments, that are already members of the RENER network, and new members that want to participate in the network extension movement. There is an express will of local authorities to participate in a major movement to promote Portuguese cities. The “ignition” key lies in the need to gain scale in order to increase the competitiveness indices.

Good practices
of green buildings An itinerary through the green buildings of the RE-GREEN project
Within the scope of the RE-GREEN - Regional policies towards green buildings - project, supported by the INTERREG IVC programme of the EC, and led by INTELI, a series of study visits passing through various European cities have been undertaken with the objective of exchanging experiences and becoming acquainted in loco with the good practices of green policies and buildings. Grenoble, in France, was the starting point of these visits, followed by Germany, with the cities of Berlin and Potsdam. The visits continued in Spain, passing through the cities of Mérida and Caceres, followed by Stockholm in Sweden. These are the cities of the cases presented herein. The visits, however, continued onto Tartu in Estonia and ended in Ireland, in the city of Dublin.

City Council of Grenoble Grenoble Alpes Métropole SEM SAGES Gaz Electricité de Grenoble OPAC 38 EDF Mixed-use eco-district (old military facilities) The first local constructions date from 1593-1595. The rehabilitation process was initiated in 2001. http://www.debonne-grenoble.fr/ The Zac de Bonne project is an urban laboratory of national reference, in that it aims to involve several agents of the construction sector in the building of a new eco-district concept that exceeds the current energy and environmental performance regulations. This project concerns some old deactivated military facilities, which were rehabilitated into a multifunctional space that is open to the city. With ambitious programme contents, the project involved the construction of 850 fractions (with about 35% to 40% of social housing), 15,000 m2 of commercial and services area, 6,000 m2 of corporate areas (new and rehabilitated) including a self-sufficient office building from the energy viewpoint, a hotel, schools, a senior day centre, installation of 8 solar photovoltaic energy microgeneration units, and the creation of extensive green areas with surrounding landscape. With the strategic objective of achieving a 30%-40% reduction in energy consumption in comparison with current construction standards, the project also set specific targets for certain criteria: • A maximum total primary energy consumption of 50 kWh/year/m2 in residential buildings; • A maximum consumption of 42.5 kWh/year/m2 for heating systems; • A maximum annual consumption of 10 kWh/year/m2 for common electrical consumption (ventilation, lighting, elevators, etc.); • 45% of domestic hot water needs met via thermal solar panels.

The main success factor for the implementation of the ZAC de Bonne project was the funding from the Concerto EU SESAC programme, complemented with the funding from the sale of lots to private developers and to the city hall of Grenoble. The planning of this district was not only a successful experience but also involved a deep learning curve for its developers and urban planning teams involved, due to the multidisciplinarity present as a result of the various specialities; The component involving raising the awareness of the estate residents was also a successful aspect in that it promoted and encouraged the adoption of energy efficient and responsible behaviour.

SIERG Office building The year of construction of the building is 1984. The rehabilitation process: May 2009 - March 2010. http://www.sierg.org/ The main objective of the rehabilitation project was a significant reduction in energy consumption and a resulting reduction in CO2 emissions. The three main areas of intervention include the reinforcement of the thermal performance of the external environment, the improvement of the levels of air quality and the inclusion of the system of renewable energy sources. The technical solutions implemented in the rehabilitation process consisted of reducing the glass areas, reinforcing the thermal isolation of the external envelope, substituting the glass frames, reinforcing the solar shading systems, insulating the roofing and installing a partial green roofing, and installing a dual flow ventilation system by resorting to groundwater pipes, as well as installing photovoltaic energy systems for microgeneration. Following the development of processes to monitor the new energy consumptions resulting from the energy rehabilitation of the building, the following results were observed: • A reduction of 35% and 89% in energy consumptions resulting from the use of heating equipment and cooling systems, respectively; • The substitution of luminaires resulted in a 43% reduction in energy consumption. • The micro-generation of photovoltaic solar energy registered annual production levels of 6,300 kWh/year, exceeding initial production targets.
Main success factors
Following the conclusion of the rehabilitation process, the company decided to launch an inquiry to assess the level of satisfaction of all employees, which demonstrated that 85% was satisfied with the rehabilitation of the building and with the new levels of comfort and labour productivity. Following this inquiry, a training programme in energy efficiency was also developed to raise employee awareness.

City Council of Échirolles AMO HQE®: Addenda Arquitectos: Arcane Arquitectos/Charon-Rampillon/R2K BET HQE®: Etamine BET Fluides: GECC AICC BET Structures: Batiserf BET Acoustique: Echologos Public services building 2006 http://www.debonne-grenoble.fr/ The ambition behind the construction of this public building was for it to become an environmental reference with the HQE seal for the category of service and commercial buildings, at a regional level. Although the HQE certification was not achieved, the building brings together a distinctive set of bioclimatic architectural solutions, particularly in terms of passive natural lighting and ventilation solutions, but also in terms of energy management systems in the building. The bioclimatic architectural solutions are evident and visible throughout the entire building, essentially applied to the ventilation and natural lighting, with the inclusion of a glazed atrium that will function as an internal temperature regulator and control the equilibrium between interior and exterior temperature losses and gains. Energy management and the general consumption of the building is controlled by a centrally-controlled BMS (building management system), whilst the lighting is managed in accordance with the solar radiation intensity and the presence of a multi-sensor installed in each office. The offices with a view of the atrium are equipped with shading systems to diffuse natural light, preserving indoor privacy and the working conditions.
Main success factors
The planning of this building was one of the main success and learning factors of this project, which enabled bringing together a group of specialists from the most varied construction specialities and amass a series of construction solutions with a high energy and environmental performance. The employee awareness raising component was also a success factor in reaching an energy efficiency level of reference, due to the placement of multi-sensors to regulate ventilation, heating and lighting in the areas occupied by the employees, so as to encourage a more efficient and responsible use of the same.

Gartenstadt Drewitz Developers Typology of building/district Year of construction/rehabilitation Link Brief description
City Council of Potsdam Propotsdam Housing Agency Social housing district The district was built in 1980. Rehabilitation process: 2010 - in progress. http://www.gartenstadt-drewitz.de/cms/?home The Drewitz district was designed under the concept of “city-garden”, developing a master plan for the creation of urban parks, the energy rehabilitation of all the buildings and encouraging the use of renewable energies. The urban infrastructures and traffic routes were also included in this ambitious plan. The strategic goals are the sustainable development of a modern district with low CO2 emissions, green infrastructures, good living conditions and good public transport connections. The specific goals are: • Reduction of the primary energy needs of buildings to values between 130 and 60-70 kWh/(m2) and definition of higher standards of energy storage for new constructions; • Development of a district adaptation model to fight against the inevitable impacts of climate change (for example, the fight against the urban heat-island effect); • Contribute to the decentralised production of energy and storage, concepts of innovative mobility and modernising energy efficiency in residential buildings of the district.
Main success factors
One of the main success factors of the project was the involvement of the residents in the various rehabilitation measures of the district. The various stakeholders and urban planners decided to promote the participation of the citizens and, subsequently, redraft the plan together with them. The main result was the establishment of a parking management plan that will be implemented by the city of Potsdam and by the housing agency (Propotsdam) in close coordination with the citizens. In addition to the social involvement, it is important to mention another successful factor of the project which was the financial support provided by the federal state of Brandemburg, which guaranteed the financial sustainability of the project.

Senate of Berlin for Urban Development - Department VI - Ministerial Affairs of Construction - Ecological Construction Section; Technical University of Berlin - Institute of Architecture - Department of Buildings, Technologies and Design; Humboldt University of Berlin – Institute of Physics; University of Applied Sciences of Neubrandenburg – Landscape Ecology Department – Botany; Office building The period of construction of the building is 1999 to 2003. http://www.gebaeudekuehlung.de/faltblatt_institut_physik_engl.pdf http://www.physik.hu-berlin.de/home/ The project is an architectural reference in terms of ecological management of green building resources and systems. The technical and scientific monitoring, the optimisation and the assessment of innovative measures for rain water management, as well as the interaction of the natural and landscape resources and the natural air conditioning systems of the building bring together the main distinctive factors of this project. The building has a decentralised management of rainwater which is stored in tanks and used to irrigate a green façade system and to generate evaporative cooling in the air conditioning systems. In addition, the composition of the plant-derived coating of the different façades of the building had an enormous impact on its energy efficiency, particularly in the equilibrium between the levels of shading and direct solar radiation on the façade, as well as the ideal evapotranspiration for the building’s interior and exterior microclimate.

Regional Government of Extremadura Regional Health Service Delegation of Extremadura Office building 2010 http://www.saludextremadura.com/es/web/portalsalud/directorio/areassalud/merida The new central office building of the Public Health Services of Extremadura intends to meet the highest demands of its customers and the criteria of economic efficiency that the current context requires from public bodies. In this regard, the construction of the centre sought to create an energy and environmental reference of regional scope, by being the first regional building to be attributed an energy class-A certification. In addition to the design of all of the building’s components and systems, the main criteria of construction focused on a highly efficient air conditioning system using renewable energies, the attainment of excellent levels of indoor air quality, minimum noise levels, efficient levels of thermal insulation and the attainment of adequate levels of natural lighting. The main energy efficiency targets achieved arise from the efficacy of the following components: • The air conditioning system is composed of an absorption machine that produces cold from the heat generated in the biomass boilers. In turn, the energy generated by the boilers is used by the air machine applying the co-generation principle; • The lighting system is composed of luminaires with sensors to maintain the levels of natural and artificial lighting suited to the various needs. • The micro-generation of photovoltaic solar energy is of 95,095 kWh/year which generates revenues of €30,430/year from the sale of electric energy produced. • The production of domestic hot water is provided through a system of thermal solar panels with a high yield and a level of energy accumulation of 34,080 MJ/year; • The management and control of the building’s lighting, air conditioning and equipment operation parameters is carried out via an automatic control system with constant and historical monitoring of all the components for greater energy efficiency. Only the cooling system has an individual control system which was designed to achieve the best seasonal performance;

New regulations on the energy performance of buildings The Council of Ministers approved a diploma that reviews national legislation on the energy efficiency of buildings, including in a single diploma legislation that was dispersed, and transposed a community directive relative to the energy performance of buildings (Directive no. 2010/31/EU, of the European Parliament and of the Council, of 19 May 2010). Decree-Law no. 118/2013 was published on 20 August and enters into force on 1 December 2013, covering the System of Energy Certification of Buildings, the Regulation on the Energy Performance of Residential Buildings and the Regulation on the Energy Performance of Commercial and Services Buildings.
European Union initiates new debate on sustainable buildings In July 2013, the European Union launched a public consultation on the impact of the life cycle of buildings, within the scope of a communication on sustainable constructions that it is preparing for the start of 2014, opening a new debate on sustainable buildings, which aims to change the certification systems in addition to the paradigm of energy efficiency. The European Commission announced at the end of June that the communication will focus on the use of resources in a wider scope, namely the energy incorporated in buildings, the use of water, construction materials and waste. The wide-ranging consultation will encompass the extraction of construction materials, through to the demolition and recycling of materials at the end of the life cycle of a property. Its results can contribute to the bases of the new energy performance certification systems of buildings in the future. The public consultation is available at: http://ec.europa.eu/environment/consultations/pdf/buildings/Sustainable2en.pdf

Modernising Building Energy Codes - to Secure our Global Energy Future
International Energy Agency (IEA) and Empowered lives Resilient nations, 2013 This report makes a compilation of good practices and lessons learnt to improve energy efficiency in the construction sector, taking into account member IEA countries and non-member IEA countries. In member IEA countries the main focus is on renovation and rehabilitation, through the implementation of energy codes and minimum performance standards for existing buildings. In non-member IEA countries an approach centred on new buildings is needed (it is necessary to build more than half of buildings until 2050), designed to be low energy consumers with codes that specify stringent performance standards.

The study highlights the growth of green buildings all over the world, based on the results obtained from a questionnaire applied in 2012 to architects, engineers, contractors, owners of buildings and consultants in the construction sector covering 62 countries. Twenty-eight per cent of respondents throughout the world say that they are focusing their work on sustainable development and construction, which makes up 60% of their green projects, in comparison with only 13% in 2009. A significant part of the results shows that this is a general trend at a worldwide level, i.e. it is not locally confined or restricted to developing countries. The reason for this growth is that green has become a business opportunity in an increasingly competitive global market.
