Irenka van den Hout the woman behind Glasshouse Communications, advises companies and organisations on best ways to communicate and to create support, both internally and externally, for their sustainability policy. She is also available as interim support, project leader, lecturer and honorary chairperson. In addition, she offers the ‘How to communicate about CSR?’ workshop


“Irenka is a savvy communications consultant with an eye for detail. As a communications advisor for the REKS (Regional Energy and Climate Strategy) of Region Heart of Brabant, she ensured that the various parties involved were able to connect through a clear communication strategy. Working with Irenka was also very pleasant. She maintained an overview and was aware of her environment. That means she was very able to translate what was needed on a communicative level and when. I can look back on a very positive collaboration.”

Sylvia Torreman, process manager Regional EnergY and Climate Strategy

“Thank you for your unbridled enthusiasm, craftswomanship and tight planning in setting up the frame of our new website, which Natuurbegraven Nederland will proudly open as a finished house in May 2021 for all who want to know more about the choice for eternal peace of grave in nature.”

Jeroen Bruning, Natuurbegraven Nederland.

“With her characteristic 100% commitment, Irenka has taken up and realised the communication activities of and for the Water in Balans program of Waterschap Limburg [Regional Water Authority in the province Limburg]Thoughtful, creative, strategic and hands-on. Always in coordination with colleagues and with external parties. The corona period has shown her creativity and vigor to be indispensable. Irenka has developed alternatives to traditional information meetings quickly, that are of lasting value.”

Marlie Berghs, Program Manager Water in Balans, Waterschap Limburg

“While Irenka was working on her assignment for SmartwayZ.NL, I found her to be a passionate, critical and professional communications consultant who combines a keen mind with a ‘can-do’ approach. Irenka successfully innovates and improves. She asks in-depth questions and is tenacious and able to motivate others. Irenka is a cordial and reliable sparring partner. I enjoyed working with her!”

Loes Peeten-Nagtzaam, Strategic Communications Consultant, province of North Brabant

“Irenka is characterised by her ‘no nonsense can do’ approach. As the acting communication manager of the Droomfondsproject Haringvliet (Haringvliet Dream Fund Project), she was responsible for the overall communication and regional marketing for this ambitious collaborative project involving six large nature organisations in the Netherlands. A role that not only demands quick forward-thinking and seizing opportunities, but also encouraging others to do the same. Irenka has demonstrated her mastery of every aspect of taking decisive action and making a vital difference by working with others. She would be an asset to any project which requires determined teamwork to achieve its goals.”

Marius Brants, Chairman of the Droomfondsproject Haringvliet

“In our close collaboration with Irenka van den Hout within the context of organising the international conference ‘SDG 17: what makes a partnership successful’, we found Irenka to be a very motivated professional, with an eye for both the broader, final result and for the detail. Through her passion for sustainability, Irenka’s knowledge of the subject matter was a valuable contribution. Irenka is, without doubt, a project manager you can rely on.”

Claar van den Bergh, Senior Advisor Corporate Engagement WWF Netherlands

“Dunea, Dune and Water, was looking for someone to act as an interim manager of the Communication Department for half a year. Irenka filled the vacancy and proved to be a professional who very quickly got to grips with the multitude of files and was then able to swiftly consult the appropriate people. Knowledgeable, with a broad background in terms of both knowledge and experience, sociable, not afraid to make choices and an affinity for drinking water and nature: Irenka demonstrated all of these qualities during her time here.”

Georgette Leltz, Manager Client and Nature Dunea

“Irenka is a very professional and reliable communication manager. She is result-oriented and her word is her bond. She takes over tasks as required and thinks in terms of possibilities and solutions. Decisive and competent. When she joined WWF Netherlands, she quickly familiarised herself with the organisation and how it works. A sparring partner for both me and colleagues from the unit. Enjoys new challenges, but without losing sight of the need to manage and safeguard existing affairs.”

Frederique Koning, Head of Communications WWF Netherlands

“Irenka is a very energetic all-round communication professional who feels at home in all ‘communication markets’. As the Head of Communication at MVO Nederland she managed her communications team brilliantly. Moreover, she has updated and professionalised almost all modes of communication, from website to house style, from internal communication to media relations and from social media to newsletters. Irenka works systematically and gives her colleagues lots of space and responsibility. She is determined and has a high output. In short, working with Irenka is a delight.”
