Seal Greenbuilding

Vircop engineering Building Systems participated in the award of the first seal for an industrial building Greenbuilding -logistics in Europe, giving us a point of excellence to our extensive experience in the design of energy efficient buildings.

GreenBuilding Programme is a European Programme which aims to help implement energy efficiency measures and renewable energy in commercial buildings. These measures not only help reduce emissions of greenhouse gases, but also allow to significantly reduce energy costs of operating the buildings.

This program awards a seal to a building Greenbuilding justified by audit, which has reduced by 25% sustainable measures such as minimum energy consumption. This national audit is exercised by the University Rovira i Virgili of Tarragona.

While several office buildings already have this label in Spain, what is really new in this case was its application to an industrial building and logistical.

The strategy consisted analyze the actual consumption of a building similar logistics characteristics, located in Madrid, and put forward proposals to reduce consumption to a new building project.

logistics projects in the major inputs are related primarily to artificial lighting (which can assume 80% of total electricity consumption) and battery charging systems.

As corrective actions gave the building a better natural lighting consisting of:

- increased lighting on the deck surface (translucent), together with a study thermal comfort.

- very detailed study of the placement of the translucent, studying the optimal allocation of shelf, so that 100% of them are located in areas of corridors.

- translucent material having higher quality, greater transparency and better performance with aging.

This measure was accompanied by the placement of a light control system with photosensors, the use of lamps and low-power self-regulating, whose purpose was to adapt the use of artificial lighting to the actual lighting conditions.

Also increased the surface photovoltaic production on deck, so that the final consumption of the building largely reduced the consumption of a reference building.

Considering Office areas, severely underrepresented in this type of project, several improvements were also analyzed. The primary energy consumption in offices are derived from the air conditioning, hot water and lighting and equipment.

The measures used were based on the use of high performance air conditioning, better insulation in the walls in general and in particular glass enclosures, addition to the application at the project level Bioclimatic architecture concepts.

To reduce consumption in ACS, it was suggested the use of thermal solar energy and push buttons or sensors that minimize the consumption, use of feedback circuits, which maintain the temperature for a period of time, etc. .

All these measures are useful when analyzing raise the useful life of a building, not just the acquisition value of it and prove that the investments pay for themselves in relatively short periods.
