Districlima was formed in 2002 to perform, for the first time in Spain, an urban network of distribution of heat and cold for use in heating, cooling and sanitary hot water. At the beggining the project was located in an area of Barcelona urbanistically remodeled to host the Forum of Cultures 2004 (Front Litoral Besòs). The project includes the design, construction and subsequent operation, through a 25-year concession, of the main production central in Forum and the energy distribution network. In 2005 and following the award of a public competition, a second stage starts with the extension of the network to the 22@ technology district. With a concession of 27 years, the network is extending its layout based on the urban development of the area and the needs of connecting new users. Districlima is the greatest exponent of energy efficiency in the 22@ area Besos, providing through its urban network of heat and cold thermal energy useful to more than 90 buildings, saving more than 17,500 annual tons of CO2 and this about 60% by reducing the consumption of fossil energies. It is an intelligent solution in a country highly dependent on foreing energy. Urban networks of heat and cold (district heating & cooling) is a centralized production and distribution of thermal energy that achieves greater energy efficiency system with less environmental impact, in addition to offer its users and other multiple economic security and quality of supply benefits. The buildings connected to the network do not have their own machinery, they reduce their electrical contracting, maintenance costs, reinvestment ... plus have more space and greater energy rating. They are innovative and sustainable buildings of XXI century. In short, the system is based on centralized production of energy (heat and / or cold), preferably taking advantage of residual energy, energy products or cooling systems (with seawater or river) and distribution to buildings through a network of pipes formed by four pipes that run underground in the streets or arranged in service galleries. Nowadays over 870,000 m2 of roof,  are heated with contracted power over 55 MW to 80 MW heat and cold, from a Central highly efficient located in the Forum area, as well as from the second Central, near the Plaza de les Glories, which has a central function of peaks and backup energy. The high efficiency of Districlima derived from the use of the steam generated by the neighboring treatment plant municipal solid waste (MSW) to produce almost all the hot water and much of the cold water. In addition, production equipment cooled by sea water, allowing to obtain yields in these machines to 4 times higher than conventional substituted equipment.

CO2 Impact

17 678 tCO2

Method used to calculate CO2 impact

El ahorro de emisiones de CO2 se calcula mediante la diferencia entre las emisiones estimadas según producción convencional y las emisiones reales del sistema.

Las emisiones convencionales proceden de la aplicación de un rendimiento de caldera doméstica y un coeficiente COP para la producción de frío doméstico. Aplicando seguidamente los coeficientes de emisión de CO2 sobre energía primaria del Manuel Técnico CALENER 2009.

http://www.idae.es/index.php/mod.documentos/mem.descarga?file=/documentos_CALENER_03_GT_Manual_Tecnico_A2009_A_f23fc148.pdf

Las emisiones reales, proceden de aplicar dichos coeficientes sobre el consumo real de energía primaria, que en el caso de Districlima SA, vapor, electricidad y GN.

El hecho que se produzca calor y parte de frío, a partir del vapor residual de baja presión procedente de una planta de Revalorización de Residuos Urbanos, hace que el ahorro de emisiones sea notablemente mayor que el de otro proceso sin esta singularidad.

Project management

    With a concession of 27 years, the network is extending its layout based on the urban development of the area and the needs of connecting new users. Districlima is the greatest exponent of energy efficiency in the 22@ area Besos, providing through its urban network of heat and cold thermal energy useful to more than 90 buildings, saving more than 17,500 annual tons of CO2 and this about 60% by reducing the consumption of fossil energies.

SOLUTIONS

    Central Forum:

    Heat and cold is produced taking advantage of the steam generated in the combustion of municipal solid waste (MSW) from neighboring treatment plant TERSA

    Production equipment are cooled by sea water, resulting in high yields, without the use of cooling towers.

    The energy management is optimized using an ice water accumulator 5,000 m3 tank.

     

    The Central has the following equipment:

    Production of cold:

    o 2 teams Broad absorption of 4.5 MW c / u.

    o 1 storage tank of cold water of 5,000 m3 (5,000,000 liters)

    o 2 electric chillers Mc Quay 4 MW c / u.

    o 2 electric chillers Johnson Controls 7 MW c / u

    Refrigeration system:

    o 3 exchangers seawater / water cooling machines 12.5 MW

    o 1 station pickup seawater 5,000 m3 / h

    Heat Production:

    o 4 steam / water exchangers 5MW c / u

    o 1 gas boiler 20 MW (backup service only if there is no steam availability)



    Central Tànger:

    Conceived as "peaks central" or pick up, ensures supply in peak periods or for any eventuality.

    It has an advanced ice accumulation system, enabling the production of energy during periods of low demand and storing it until, in periods of peak demand, its distribution is necessary.

    The flue gas from boilers are expelled through the historical chimney of the old factory of Ca l'Aranyó.

     

    It opened in April 2012 and, in a first phase, it has the following equipment:

    Production of cold:

    or 1 compression equipment of 6.7 MW for the production of glycol water

    o 1 compression equipment of 6.7 MW for the production of glycol water (commissioning phase)

    Heat Production:

    or 2 boilers of 13.4 MW natural gas for hot water production

     

    In second phase is planned to install the following additional equipment:

    Production of cold:

    o 1 compression equipment of 6.7 MW for the production of cold water

    Heat Production:

    o 1 natural gas boiler of 13.4 MW for the production of hot water

     

Quality of life / density

The Districlima solution helps to improve the quality of life of neighborhoods by extending its network for several reasons:

o The lack of machinery for air conditioning in buildings connected to Districlima translates, among others, in the absence of noise and vibration in buildings and thus improving the acoustic quality of the city.

o Similarly, there is also an environmental temperature improvement in the neighborhood, being drastically reduced the number of equipment that cool the interior of the buildings, at the cost of emitting heat to the outside.

o Reduction of overall consumption of water and chemicals: removal of cooling towers and other water consuming equipment and chemical additives (biocides, water treatment, etc.)

o And of course reducing CO2 emissions and reducing fossil energies (explained in another section).

 

In addition to these overall benefits to the city, users of the buildings connected to the network, enjoy the following advantages:

o Guarantee of energy supply: the network of heat and cold have redundancies in both production plants and thermal production equipment

o Outsourcing service of thermal production and associated risks (regulatory, commitment to quality service ...).

o Elimination of replacement cost of machinery.

o Reduced maintenance costs.

o Trouble Shooting.

o Reducing costs of supply of conventional energy (gas and electricity). Minor powers to hire

o Flexibility and adaptability. Facility to have more power, simply expanding energy exchangers, with little need for more space.

 

Culture and heritage

The buildings connected to the network Districlima contribute to the enhancement of the architectural environment: their facades and roofs are completely clear and free of machinery, fireplaces (tufted) and facilities. This translates into a differentiated real estate with innovative, unique and iconic buildings, unrestricted architectural creativity.

Moreover, Districlima also integrates the historical heritage of the neighborhood and in their own facilities: the Central Tánger leads the combustion gases from boilers through an underground conduit that expels the 36 meters brick chimney of  the former textile factory "Ca l'Aranyó", built in 1872 by Claudi Arañó i Arañó similar to the textile industries of Manchester.

Both stations, Forum and Tànger have been designed to integrate harmoniously into the environment: the first under a covered dune vegetation and the second, built in the heart of the 22@ technology district, following the adjacent building and also vegetated on its facade.

Ambient air quality and health

Districlima is a very efficient solution from an environmental point of view: all heat and part of the cold are produced from the steam generated in the neighboring plant of waste recovery (RSU) of Tersa, which means that only in the year 2015 Districlima has avoided the emission into the atmosphere of 17,678 tonnes of CO2, with a reduction in the use of consumption of fossil energy of 59%.

Being a centralized system, any improvement in the Central energy production or the production system itself resulting immediately in buildings connected to the network, also obviously the sustainability of Districlima solution: the buildings connected to the Districlima network are sustainable and with high energy rating buildings, in line with growing market awareness and administrations, stepping forward to meeting next mandatory European standards. These buildings can improve energy certification up to 2 letters (and up to 6 letters in paragraph HVAC and ACS).

In addition, the buildings connected to the network Districlima enjoy the elimination of health risks, the   removal of cooling towers and other potential sources of legionellosis elements. Districlima network of Barcelona has avoided the installation of up to 120 cooling towers in the city.

Smart City strategy


Districlima is the best performing Smart City in the city of Barcelona and Sant Adria de Besos for 10 years through a system of data collection that uses its own private fiber optic network, which allows continuous monitoring of production, adapting at every moment to the availability of the territory and decision making in real time by transforming big data through the sensing information in active configuration tools and decision-making.

Climate adaptation, resources conservation, GHG emissions


The environmental benefits of Districlima for the city are obvious: reducing CO2 emissions (17,678 tons in 2015), refrigerant leakage reduction (-> ↓ CO2), waste revaluation, higher energy efficiency (-> CO2 ↓) reducing the number of cooling towers, lower overall consumption of water and water treatment products …

Energy sobriety


In the present times with rates of energy importation hovering 70%  in Spain, it is very important to make an intelligent search of ways of generating energy taking into account the territory. This is not something new, and in historic Pompeii geothermal sources was resorted to the hot springs, and Paris has for 100 years a network of heat and a network of cold for 30 years. We must start from two premises. On the one hand there is no universal false solutions and the other is essential to have a sense of scale. Search in each territory of possible energy sources to assemble a network of heat and cold in each case will be different: incinerators, sewage treatment plants, rivers, sea, etc. In the case of Districlima the power source is in the heat produced by the incineration of municipal solid waste (at the nearby plant waste recovery - Tersa) integrated in the landscape under a green mountain plant that uses water the sea for cooling their equipment.

Buildings

 

The Districlima network is over 15 km in length and more than 90 buildings of all types are connected to it: offices, hotels, schools, housing, technology and production centers, municipal facilities, museums ... and within very little (in 2017) it will also be connected to the Hospital del Mar, a reference Hospital rushing a large comprehensive reform that also includes the migration of the conventional air conditioning with own machines and fossil energies to air conditioning Districlima efficient.

Some of the buildings connected to the network Districlima also participate in the Green Building Soluctions & City Awards, such as: Twentytú Hi-Tech Hostel, housing street Roc Boronat CEIP Sant Martí or the Leitat Technology Centre

Reasons for participating in the competition(s)

​Districlima fue constituida en el año 2002 para llevar a cabo, por primera vez en España, una red urbana de distribución de calor y frío para su utilización en calefacción, climatización y agua caliente sanitaria. Inicialmente el proyecto se ubica en una zona de Barcelona remodelada urbanísticamente para acoger el Fórum de las Culturas de 2004 (Front Litoral del Besòs). El proyecto engloba el diseño, construcción y posterior explotación, a través de una concesión a 25 años, de la central de producción del Forum y la red de distribución de energías.En 2005 y tras la adjudicación de un concurso público, se inicia una segunda etapa con la extensión de la red al distrito tecnológico del 22@. Con una concesión a 27 años, la red va extendiendo su trazado en función del desarrollo urbanístico de la zona y las necesidades de conexión de nuevos usuarios. Districlima constituye el máximo exponente de eficiencia energética en el 22@ y zona del Besòs, suministrando a través de su red urbana de calor y frío energía térmica útil a más de 90 edificios, aportando un ahorro de más de 17.500 Tn anuales de CO2 y ello reduciendo cerca del 60% el consumo de energías de origen fósil. Se trata de una solución inteligente en un país altamente dependiente del exterior en materia energética.Las redes urbanas de calor y frío (district heating & cooling) constituyen un sistema centralizado de producción y distribución de la energía térmica que permite alcanzar una mayor eficiencia energética con un menor impacto medioambiental, además de ofrecer a sus usuarios otros múltiples beneficios económicos y en materia de seguridad y calidad del suministro. Los edificios conectados a la red no disponen de maquinaria propia, reducen su contratación eléctrica, sus costes de mantenimiento, las reinversiones…además de disponer de mayor espacio disponible y de una mayor calificación energética. Son edificios sostenibles e innovadores del s XXI. En síntesis, el sistema se basa en la producción centralizada de energía (calor y/o frío), preferentemente aprovechando energías residuales, subproductos energéticos o sistemas de refrigeración (con agua de mar o de río) y su distribución a los edificios mediante una red de canalizaciones formadas por 4 tuberías que discurren enterradas en las calles o dispuestas en galerías de servicio.Actualmente se climatizan más de 870.000 m2 de techo, con unas potencias contratadas de más de 55 MW en calor y 80 MW en frío, desde una Central de Energías altamente eficiente ubicada en la zona Fórum, así como desde la segunda Central, cerca de la Pza de les Glories, que tiene unas funciones de central de puntas y backup. La elevada eficiencia de Districlima deriva de la utilización del vapor generado por la vecina planta de tratamiento de residuos sólidos urbanos (RSU) para producir la práctica totalidad del agua caliente y buena parte del agua fría. Además, los equipos de producción refrigeran mediante agua marina, lo que permite obtener rendimientos en estas máquinas hasta 4 veces superiores a los equipos convencionales sustituidos.
