European Project Coralis, for a more sustainable world

Coralis is a Project funded by the European Union and coordinated by the CIRCE Foundation, in the framework program H2020-EU.2.1.5.3. Sustainable, resource-efficient and low-carbon technologies in energy-intensive transformation industries. The European Commission (EASME), together with the participation of 29 partners, will collaborate closely for 4 years, with a budget of almost 18 million euros, to achieve its purpose. One of its main objectives is to create new relationships in the value chain, through innovative approaches that allow and extend the Industrial Symbiosis (IS). Raising technological factors, decarbonizing industrial areas, moving towards a circular economy and establishing optimal conditions for sustainable operation, thus saving on resources and energy. It is expected to develop a Virtual Evaluation Platform that manages the IS data, for application to a real industrial environment. ... +info

Heating an industrial warehouse

Providing a large space, such as an industrial warehouse, with the necessary conditions to obtain an optimal temperature for the health and comfort of employees, is not an easy task. To be able to create an adequate work environment for all workers, it is necessary that the temperature in winter is between 20ºC and 24ºC, with a relative humidity of between 30% and 70%. However thermal well-being also depends on subjective factors, such as the physical activity carried out and the clothes used. For this reason it is calculated that for a warehouse of about 200-250 m2, for a temperature differential of 20ºC and a normal isolation, a power of 10.000 Kcal/h is necessary, which can vary depending on the differential and isolation. There are different heating systems in the market, and the most efficient choice can lead to great savings. Electric heaters: they use electricity as an energy source and heat the environment quickly, cleanly and safely.Combustion heaters: their sou... +info

Ventilation in industrial warehouses

Industrial warehouses require complementary ventilation systems, as natural ventilation is not enough, due to their size and distribution. Usually these systems are obsolete, fail or directly there are none. Industrial warehouses require complementary ventilation systems, as natural ventilation is not enough, due to their size and distribution. Usually these systems are obsolete, fail or directly there are none. Air quality is essential for the health of the workers inside the buildings. Breathing poor quality air causes serious problems in the respiratory tract, headakes, anxiety, or irritation of the mucous membranes, eyes, nose or throat. It is advisable to reinforce the cleaning of the air filters, renewing the indoor air and increasing the ventilation of the ventilation systems, about 4-10 renewals/hour. Thus controlling humidity, improving the thermal conditioning, reducing the concentration of gases, favouring the extraction of smoke in case of fire and avoiding the ent... +info

Women build

L’Hospitalet del Llobregat Town Hall collaborates with the Construction Labor Foundation in Catalonia in the project “Women build” This project consists of a 126-hour training for 12 unemployed women in the locality. And its aim is to bring unemployed women closer to a sector that offers opportunities for quality employment, and where women are under-represented.   The good news is that more and more women are trained and working in the construction sector. ... +info

Brussels project to renovate 35 million buildings by 2030

The European Commission has presented a strategy to rehabilitate and renovate 35 million buildings and homes by 2030, with the aim of making them more energy efficient and contributing to meeting climate targets. It is a sector responsible for 40% of energy consumption and 36% of greenhouse gas emissions, but only 1% of buildings undergo energy-efficient renovations each year. For this reason, the proposal gives importance to reduce emissions by 55% in 2030 and achieving carbon neutrality by 2050. Strategy priorizes for :       The decarbonization of heating and cooling systems.       Adressing energy poverty and less efficient buildings.       Renovate public and administrative service buildings. This project also aims to trigger a transformation of our cities, improving people’s quality of life, encouraging digitalization and improving reuse and recycling of materials. ... +info

Reversibly clean damp walls

Humidity is a problem that affects many buildings. We can find it in walls or interior walls with mold or damaged by salt. The main problem is that it slowly penetrates the wall, so the treatment must be very careful, eliminating the causes that originate it to restore a healthy climate throughout the building. There is a system that has been designed to reversibly clean up these damp walls, its name is Biodry Technology. This eliminates the humidity of capillary rise from the walls, permanently. With the aim of providing a definitive, ecological and biocompatible solution to the world of construction. The dehumidification process is monitored with constant controls, and with a rigorous measurment protocol. It is not necessary to connect it to the electrical network, in this way its operation is ensured without producing any kind of electromagnetic field that could generate interference with other devices. This technique detects the moisture both in the plaster and insid... +info

Safer offices against COVID-19

To prevent the contagion of COVID-19 in offices, as elsewhere, the safety distance set by health authorities must be maintained. The mask must be used correctly. Especially when we move from home to work, so as not to infect others and protect ourselves. When entering and leaving the work center, it is advisable to take turns. In this way, we avoid a large interrelationship in small places. It is recommended not to touch your eyes, nose and mouth and wash your hands with soap and water frequently or with a hydroalcoholic solution. Especially after coughing or sneezing, and if we do, we should cover our noses and mouths with the inside of our elbows or a disposable handkerchief. Regular ventilation of the facilities is recommended to help renew the air. Coronavirus transmission occurs especially by having direct contact with an infected person or by touching contaminated surfaces. For this reason, it is appropriate to maintain good space hygiene. It is important to do a g... +info

Sectorization against fires in industrial buildings

A fire in an industrial company can cause great impact on its activity, facilities, machinery and raw materials, but above all because of the risk it poses to the lives of its workers. Nowadays, the law obligues companies to implement a sectorization in their warehouses, for more protection against possible fires, and in case they occur, to minimize their impact and severity.  One of the most efficient passive protection systems is the firewall strips. They can be located on roofs facades or as sectoring elements in partition walls. Thus preventing the spread of fire, and avoiding damage to other sections of the warehouse or adjoining industrial buildings. The firewalls must be build of fire-resistant materials with load-bearing capacity, integrity and isolation. Composites are usually used with a combination of different materials. By dividing the space into different volumes, the fire can be limited only to the place where the fire has been declared, thus allowing the eva... +info

Rehabilitations and reforms,
as a measure for economic recovery

Rehabilitation and reform are a fundamental sector with a lot of potential on the economy and that will contribute to its recovery, representing more than 40% of the value of the materials of the construction as a whole. It is of vital importance to encourage demand in the coming months, and agree on a strategy with the contributions of political forces, to cope with the coronavirus crisis. The reform implies a huge volume of labor and provides added value to the consumer market. As this is a lasting investment, it helps to increase the value of the building and quality of life of those who use it.  In addition, as part of the EU Green Agreement, the European Commission has announced the Renovation Wave initiative to boost energy efficiency and the renovation of the building stock in Europe, to achieve the climate goals set out in the EU Green Pact. At Duinsa we focus our activity on the study, development and realization of works, both new construction and remodeling, reha... +info
