18th International Passive House Conference 2013

Session VIII: EnerPHit refurbishment

Friday, 25 April 2014

16:00	Ludwig Rongen \| Heinsberg Protestant Christ Church – EnerPHit refurbishment, conversion and extension Interior insulation was added to the Christuskirche church in Heinsberg as part of an energy-focused retrofit in line with the EnerPHit Standard. The planning process included an analysis of the conditions for the retrofit, especially the suitability of the brickwork, based on laboratory studies carried out by IBAC and simulation calculations conducted by PHI.
16:25	Stefan Oehler \| Conversion of a trading post into a multy-family building with lofts A fashion company’s warehouse was turned into a modern multi-family building with loft apartments with Passive House components at low cost. The renovation had to be extended for cost reasons so the EnerPHit standard will be attained in two phases. The first phase paved the way for all measures that will be included in the second phase.
16:50	Georg Reinberg \| Passive House refurbishment with extension and redensification under challenging conditions In Kierling bei Wien, a residential complex originally built in 1979 underwent a retrofit while inhabited, and a timbered annex was added to the roof. A new building was also constructed, and both buildings now have central heating based on solar and biomass. Central Passive House ventilation heating lowered the cost of the retrofit.
17:15	Eva Anlauft \| Cultural heritage preservation award for an energy retrofit – prevention of structural damage, costeffectiveness and regulatory compliance In 2001, the City of Nuremberg began installing interior insulation in the Herrenschiesshaus, a protected heritage building constructed in 1582-83. Measurements from behind the insulation and at the wooden beam heads show that the structures are free of damage. The complete retrofit of the building was completed in 2011. Heating energy consumption is now about half what it was before the retrofit. In 2012, the retrofit project was awarded the Bavarian Cultural Heritage Preservation Prize.
17:40	Oliver Ottinger \| Comparison of four interiour insulation systems – measurements and hygrothermal simulations The measured temperature and relative humidity evolution in a wall construction with four different interior insulation systems is compared with hygrothermal simulation results. For better adoption a parameter variation is conducted and results are discussed. Poster Contributions: 1) Reinke \| From a traditional Hamburg detached house to a low-energy house with a Passive House extension 2) Graf \| EnerPHit – an early pilot project 3) Rongen \| Passive House refurbishment of Baesweiler‘s secondary school – monitoring and user survey
