Who is sustainable Homes Scotland?

We are a team of various professionals who would like to drive on sustainable housing in Scotland.

Thomas is a German engineer who made his master degree at the University of Building and Engineering of Munich. He was responsible in building the 1st prefabricated Passive House for “Wolf Haus” at the Show house park in Munich Poing.

Educated and experienced in German and British building industry, Thomas knows the ins and outs of how to build sustainable.

After moving to Britain he became main responsible for the Austrian Window Manufacturer “INTERNORM” in the UK and a lecturer in passive House windows for the BRE.

Stephen has made his degree in business administration in 1988 in Germany and has been working as a manager in sustainable transport for many years.

As a director of a Scottish building company, he got involved in sustainable housing. He is enthusisatic to pass on the experience and knowledge, which is available in many European countries in energy saving building technologies.

Ian Theoboldt, Energy Consultant (TheoTeC)

Ian Theoboldt has been involved with sustainable energies for over 20 years. The main focus always was and still is practicality and affordability, a main concern being independence from fossil fuels. This goes hand-in-hand with raising the general level of environmental awareness amongst the population.

Because it is still better to reduce energy use in the first place, Ian also is involved in developing low-energy and passive houses.

Academically educated in Germany where he worked many years in the research and development field and as a Quality Manager, Ian moved to Scotland to start his own company in the year 2000. Moving on again once more, he now continues his Energy Consultancy in Sweden, a “citadel” for sustainable energies, where the government aims 75% of all housing stock to be according to or at least similar to German passive house standard by the year 2020 – the year by which Sweden plans to be completely “oil-free”.
