BUILDINGS ATTACHED TO THE TERMINAL OF THE PORT OF LISBON
Next to the new passenger terminal in the port of Lisbon, designed by architect Carrilho de Graça, there are two buildings with innovative facades and roofs. They were designed by the same author of the terminal and were built of lightweight materials with high insulation capacity, which act as a passive solution to reduce the energy consumption of buildings.
Flat roofs were made of Isodeck PVSteel sandwich panels from Isopan.
In addition to the new passenger terminal in Lisbon, designed by Portuguese architect Carrilho de Graça, there are two buildings for Heden's coworking facilities. Common work environments that are defined to prioritize healthy programs, create open spaces, and encourage collaboration between resident companies and professionals. At the same time, however, it supports development based on sustainable and ecological criteria, where it is possible to embed architectural solutions capable of reducing energy consumption and the impact of buildings on the environment.
Its features include photovoltaic panels capable of meeting most of the building's energy needs, bioclimatic green facades equipped with passive cooling, solar systems with adjustable facade ribs in combination with wooden and bamboo curtains, and the use of energy-efficient LED lighting. According to the owner's calculations, all these interventions could lead to savings of up to 30% of energy consumption in both buildings. In addition, the roofs have been designed as a passive cold roof, which reduces the use of air conditioning and air conditioning systems and, as a result, offers greater energy savings.
ROOF AS A PASSIVE COOLING ELEMENT OF THE BUILDING
The roofs are the skin of the building most exposed to sunlight. Choosing transparent building materials for the roof is a passive way to help reduce the energy needs of the building in which it is installed. For this reason, it was decided to create highly reflective light gray roofs with Isopan Isodeck PVSTeel sandwich panels for these additional terminal buildings, which also offer better thermal and sound insulation thanks to the stone wool core. Renolit brand high reflectivity, high SRI, low contamination and high thermal emissivity boards were added to these panels. These boards ensure that the roof does not absorb all the UV radiation that falls on it, thus preventing surface heating and heat transfer to the interior of the building. With this passive cooling or cold roof solution, not only is the buildings overheating smaller, but also the dreaded heat island effect, which is a phenomenon of urban centers overheating compared to the surrounding areas, as well as reducing minimum CO2 emissions from heating and cooling systems.
