The Passive House Turns 25: Börner Congratulates and Joins the Party

The Passive House Turns 25:
Börner Congratulates and Joins the Party

The main focus of this year's 20th International Passive House Conference is the 25th anniversary of the passive house as well as future trends of passive house components. Also the Hans Börner GmbH, the specialist for passive house skylights, is exhibiting innovative passive house compo­nents at the trade exhibition in the architecturally impressive congress center "darmstadtium" on the 22nd and 23rd of April. Börner's exhibition stand informs about energy benefits, the latest technical requirements and sustainability.

At stand number 7.3, the experienced team of specialists for skylights and striplights is looking forward to answering questions by trade visitors. In addition, the versatility of the certified skylight, which is globally unprecedented in its category, will be demonstrated by means of a skylight at the exhibition stand. The skylight with arched acrylic glass received the award "phA Advanced Compo­nents" by the Darmstadt-based Passive House Institute in the first attempt. This means that it corresponds to the highest efficiency class that can be achieved by components suitable for passive houses.

Passive house skylights as part of sustainable, energy-efficient building concepts contribute to save energy by utilizing natural light. All skylights consist of a sextuple-skinned acrylic dome with defined rise. The spaces between the skins are filled with air. The glass thickness package is 93 mm. The outer skin is insulated with PUR foam. A skylight can reach a total thermal transmittance value of USL = 0.67 W/m²·K. Their specific design prevents critical surface temperatures on the inside.

When the first international passive house was built in Darmstadt, Germany, 25 years ago, the project had been an experiment. In the meanwhile, the resulting standards for energy efficiency have become an integral part of the construction industry and businesses and residents alike benefit from the reliable savings of up to 90 percent of heat energy. In a growing number of cities such as Frankfurt, Brussels and New York, this standard has become the benchmark for public buildings.
At the same time, the passive house already meets the future requirements of the EU for climate-friendly construction.

In addition to long-term experiences, the International Passive House Conference 2016 is also presenting many new industry achievements. Amongst other trends, also buildings will be presented meeting the criteria for a passive house plus or passive house premium by combining efficiency with renewable energy.

The program of the conference is enriched by a series of workshops and excursions to passive houses in Darmstadt and the surrounding area. Also the world's first passive house, built 25 years ago in the Kranichstein neighborhood, can be visited.

The International Passive House Conference takes place at different locations yearly since 1996 organized by the Passive House Institute. Since its premiere 20 years ago, it is now the first time that the conference is returning to Darmstadt. This year, the conference is co-organized by the city of Darmstadt, the Department of Civil Engineering of the University of Darmstadt and the University of Innsbruck. The Hessian Ministry of Economics, Energy, Transport and Regional Development has assumed patronage of the conference. Moreover, some of the lectures are embedded in the EU-funded project EuroPHit (energy retrofits step-by-step). Conceptual sponsors include the Hessian Architects and Town Planners Chamber and the German Federal Environmental Foundation (DBU).
