Monitoring confirms efficiency of Passive House tennis hall in Sweden

On the tennis court, Stefan Edberg was the number one for a long time – today the Swede is reaching top scores with his own indoor sports centre. As the first of its kind, the "Södra Climate Arena" in the city of Växjö was built to Passive House Standard in 2012. New monitoring results not only confirm the low consumption values, but the heating demand during the first two years of operation was even lower than anticipated. A user survey also indicates a high level of satisfaction with the comfortable conditions inside the hall. more

Concept of step-by-step building refurbishment honoured with award

A concept developed by the Passive House Institute for the energy-focused modernisation of buildings has won first prize in a competition. The award jury especially lauded the approach of a "refurbishment road map" with appropriate individual steps. The concept was largely developed within the framework of the EU funded EuroPHit project. The intent is to provide both a certification of such "overall road maps" as well as an energy assessment of the individual refurbishment steps in the planning tool PHPP. more

New designPH takes Passive House planning to a whole new level

Passive House planning has never been more convenient. The new designPH, a 3D model interface developed by the Passive House Institute, allows for graphic input of energy related design data. Details relating to the thermal building envelope and shading are entered automatically and can be optimised if necessary. The treated floor area can be gradually refined in order to simplify the design process. The results can be exported into the Passive House Planning Package (PHPP) with just a few clicks. more / order now

Passive House Standard central to New York City Mayor's plan

New York is taking serious steps towards climate protection by low-energy construction: Mayor Bill de Blasio's new plan to dramatically reduce greenhouse gas emissions from city buildings by 2050 relies on Passive House as a guiding standard for new construction and existing building renovation. The One City: Built to Last plan, released in September, says that nearly two-thirds of greenhouse gas reductions in New York City must come from more efficient buildings. NYPH Press Release

New Passive House categories also rate building energy gains

The efficiency of the clearly defined Passive House Standard has been proven thousandfold – to also offer a reliable means of orientation regarding the additional use of renewables, the Passive House Institute now introduces new categories. These will not only take energy demand into account, but also energy supply through, for example, solar panels. In this way, Passive House offers an attractive solution for the energy revolution while serving as the basis for the "Nearly Zero Energy Building" of the European Building Directive. more

Passive House also provides answer to energy efficiency in the tropics

Whether in India, Singapore or Brazil – Passive House principles also work in tropical climates. The focus, however, changes: while heating is typically not needed in these climates, efficient cooling and dehumidification methods play an important role. A new study by the Passive House Institute gives concrete design recommendations, showing that, in the Passive House of the tropics, energy demand is also drastically reduced. The entire study is now available online on the knowledge platform Passipedia (member area). more
