Luxembourg Strassen 2011 Ecological Horizon is a near-zero energy building in Luxembourg City. It combines strong concern for architectural efficiency with the desire for very high energy performance. It is equipped with 900 sqm of photovoltaic cells which produce the greater part of its energy needs, exceeding national regulatory standards. In addition to a high quality protection against the sun’s rays, thermally-activated concrete slabs regulate both heating and cooling. The ventilation system combined with a heat recovery unit increases comfort while reducing energy costs. The building design is simple and flexible, combining open plan with individual office units. A multitude of design options are available to satisfy a wide range of working styles.
