ArchitekturWerksatt Vallentine GmBH

In 1996, Gernot and Rena Vallentin founded ArchitekturWerkstatt Vallentin GmbH . Since then, they have realized many exemplary Passive House flagship projects within Germany and internationally. Their notable projects includes the worlds first Passive House school (Germany), the Youth Guest House and the LOHAS Seminar Building (Largest Passive House in Korea and Winner of the International Passive House Award 2014) and the recently completed Passive House Experience Center in Qingdao/ China. Both Passive House planners focuses their work on beautiful contemporary design, optimal technical solution and cost effective implementation. They have worked alongside the Passive House Institute and the Bavarian Ministry of Economics to develop the Passive House PLUS Standard for artic and tropical climates, the Building 4.0 Standard. For his work and contributions, Gernot Vallentin has been awarded the Bavarian Environment

Stefanos Pallantzas

Civil Engineer (NTU Athens, specialized in major project management), Certified Passive House Designer and Accredited Building Certifier, Co-founder and president of the board of the Hellenic Passive House Institute, member of the Affiliates Council of the International Passive House Association (iPHA) and the Scientific Committee of the International Passive House Conference. Accredited Passive House Course Trainer by Passive House Institute In 2009 he successfully completed the first Passive House Standard in Greece. Since then he actively supports new PH projects in several cities in Greece, Cyprus and Turkey and the Mediterranean area. He has made several presentations about the Passive House Standard in Prof. Dr. Helmuth Gesch

Former Vice-President and scientific director of the Micro Systems Technology Cluster at UAS (University of Applied Sciences) Landshut in Bavaria, Prof. Dr. Helmuth Gesch is an expert in Passive House concepts. He has been involved in Energy Plus Buildings, where Home Automation and Energy Storage systems were integrated to obtain a high level of self-sustaining energy sufficiency. At present, he is actively transferring this modern building concept to the ASEAN region.

CURRENT PHPP CALCULATIONBeijing Double Villa Upgrade to Passive House Refurbishment Standard (EnerPHit) - - We have reached a very good building envelop, super insulated, with GOOD QUALITY OF WINDOWS and on the right position and with REDUCED THERMAL BRIDGES. We also expect to improve the AIRTIGHTNESS of the building in order to meet the criteria (1,0 ACH AT N50)PHPP

CURRENT PHPP CALCULATIONBeijing Double Villa Upgrade to Passive House Refurbishment Standard (EnerPHit) - -

The designed ventilation system ensures best quality of indoor air, no risk for mold and cold surfaces.We will use three separate units, one bigger for the basement and one for each villa. The recovery efficiency of every unit is more than 80%. All units are combined with a ground heat exchanger system (water brine) and water coils , to preheat (and defrost) and precool the air. Outdoor air will always come into the building in temperatures over 17C IN WINTER and 27C IN SUMMER. Average air change of the building will be 0,37 ACH. Expected average CO2 concentrations is around 400-500 PPM. PHPP

PHPP_ ENERGY BALANCE HEATINGBeijing Double Villa Upgrade to Passive House Refurbishment Standard (EnerPHit) - - The heating demand is 18 KWh/ma (with criteria on 25 KWh/ma) and the heating load is 13W/m TFA. This doesnt allow us to cover the heating of the entire building by preheating the air via the ventilation system. So the additional heating source will be heat pumps.

PHPP_ ENERGY BALANCE COOLINGBeijing Double Villa Upgrade to Passive House Refurbishment Standard (EnerPHit) - -

Also cooling demand and load are very low, so the same heat pumps will cover easily the needs for cooling.

PROPOSED HEAT PUMP Beijing Double Villa Upgrade to Passive House Refurbishment Standard (EnerPHit) - -

APPLICATION Two 16KW heat pumps will cover the needs of the building (100% for heating and 100% for DHW.) Two 500l storage tanks will cover the hot water need. During summer the system will support the cooling and if needed DHW.

DEHUMIDI-FICATION Beijing Double Villa Upgrade to Passive House Refurbishment Standard (EnerPHit) - - Climate conditions show that there will be long periods of high humidity. DehumidificationWill be covered by the heating and cooling system and the ventilation, but still areas, especially in the basement and 2nd floors will need additional dehumidification. Efficient dehumidifiers can be installed locally.
