Velux showed its new solutions for energy savings in buildings in Construtec 2008

The master of ceremonies of the presentation held in the Velux stand at the fair was Peter Poole, CEO of Velux Spain. The head of the firm explained that Velux defines three fundamental ingredients to enjoy sustainable comfort, that is, the ability to obtain high standards of indoor comfort, and to reduce or eliminate the energy consumption. Poole listed three ingredients that pursues his company: energy efficiency, interior comfort and the use of renewable energy sources.

In that regard, the European and Spanish authorities are already beginning to take action on the matter. Without going any further, and as discussed from Velux, article 18 of the energy performance of buildings directive recommends strategies to enhance the thermal performance of buildings during the summer, such as passive cooling techniques that improve indoor climatic conditions.

"In Velux we joined in the interest of institutions and companies committed to sustainability and social responsibility, values which are the basis of our work." "We are pleased to be able to contribute with the research and development of new solutions to achieve optimal levels of interior comfort with minimum energy consumption," he claimed to Poole.

Another new proposal of Velux is 'Power saving' function, incorporated in command of the electrical and solar window. Peter Poole, CEO of Velux Spain explained, while conducting a demonstration of the operation of the command, which is a series of variables that take into account the temperature and local media, the orientation of the Windows and its location, among other factors. "When the program has been activated, the sequence starts automatically at predetermined times." Times have been established to ensure that products of sunscreen (blinds and awnings) will rise or fall depending on the year season and the time of the day. For example, during the summer in the South of Spain sun protection products it will come down to an hour for the morning and go up at night, and otherwise in the winter. "In addition, the colour distinguishes automatically between weekdays and the weekend", concluded Peter Poole.

The blind electric or solar is the perfect complement to optimize the functioning of the new system, which allows reduction of 97 per cent of the solar radiation in summer.

Within the multiple elements of the building, the value of the Windows as energy contributors it is increasingly evident, according to Velux Spain. A studied placement of them allow thermal solar gain and to ensure adequate ventilation, which leads to an energy saving of housing energy consumption of approximately of 30 per cent according to studies, corroborated by the French Institute CSTB.
