Text description provided by the architects. i+R Group Corporate Headquarters was designed to unify the company under one roof, placing focus on work environment, construction methodology, and integration into the urban context.
Serving as an example of both the company philosophy (“We build the future”) and construction know-how of the 110-year-old family-owned construction firm, the headquarters strove to achieve innovative energy solutions, high building standards, and an attention to architectural detail and personal comfort. It was the first office complex in Vorarlberg to receive the internationally accredited LEED (Leadership in Energy and Environmental Design) certification, thus meeting the highest standards for green and sustainable building. Its modular design allows for the four stories of the building to be arranged in a variety of layouts to maximize its 3300 square meters of space for the approximately 130 staff members. The building is connected vertically by two atriums which serve as the cores of the building, and allow for daylight as well as egress.
The building′s climate is regulated using geothermal energy, with the heat pump′s power provided by a photovoltaic array which also meets seventy percent of the building′s energy needs. The southern side of the building is covered in a unique solar shade to avoid harsh summer sunlight, while still contributing to natural daylight throughout the building, reducing energy needs related to lighting by seventy percent. The construction methodology exemplifies the i+R Group′s building skill, using mostly renewable, regionally sourced material, recyclable resources (e.g. old fishing nets used as flooring), and products manufactured by the company – concrete (structural parts), wood (infill) and wooden windows.
