Dieter Herz started with Low Energy Buildings in 1995 and designed the first Passivhaus constructed in Bavaria 1998. Herz&Lang was founded in 2002. The foundation of the company was the early entry into the Passivhaus market. The company has long term experience in relation to overall design of buildings and quality assurance. This led to a steady developed knowledge about Passivhaus certification standards in residential nonresidential buildings and refurbishments (EnerPHit).v With this special knowledge the company started with their Passivhaus consulting services in 2005 and accompanied certified Passivhaus buildings with a summary of buildings costs reaching in 2013 over 400 million euro in several countries, with a diverse range of focused teams and clients. The company is also accredited with Passivhaus Certification.


King Shaw Associates Ltd


King Shaw Associates is a UK based practice specialising in low carbon, sustainable design for buildings, providing a high level of expertise across a wide spectrum of engineering disciplines. Our engineering design solutions are developed uniquely for each project of any size rather than an off the peg engineering solution. What distinguishes KSA in delivering Passivhaus projects, as an energy and occupant comfort standard, is the use of thermal modelling for predicting any issues during the design stage (ie. overheating, condensation, thermal comfort). Various design and construction alternatives (U-values calculation, solar control methods, passive design strategies and others) are then provided.
