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 world’s 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

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 CALCULATION

Beijing Double Villa – Upgrade to Passive House Refurbishment Standard (EnerPHit) 北京城堡别墅 - 被动式节能建筑优化标准 - 建筑设计与方案更新和咨询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)

CURRENT PHPP CALCULATION

Beijing Double Villa – Upgrade to Passive House Refurbishment Standard (EnerPHit) 北京城堡别墅 - 被动式节能建筑优化标准 - 建筑设计与方案更新和咨询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 17°C IN WINTER and 27°C IN SUMMER. Average air change of the building will be 0,37 ACH. Expected average CO2 concentrations is around 400-500 PPM.

PHPP 计算工具

PHPP_ ENERGY

BALANCE HEATING


The heating demand is 18 KWh/m²a (with criteria on 25 KWh/m²a) and the heating load is 13W/m² TFA. This doesn‘t 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.

BALANCE COOLING

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

DEHUMIDI-FICATION


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. 除湿设备

WHAT DOES BUILDING 4.0

MEAN?

The term 4.0 implies the 4th technological revolution in building construction

o Basing on ‚Internet of Things‘o Application of internet based

production and communicationo Building construction as well as

building operation compose a decentralised system which is self-learning, self-organised

Energy efficient building structure on highest technology level

o as it is in Passive House Concepto Applicable for all climate zoneso Applicable for all buildings

Building Automations System is the heart of a BUILDING 4.0

o Make the building ‚Smart‘o Applicable for all climate zoneso Applicable for all buildings
