You have me this week.

Sitting at home on a beautiful day with the window open, I wonder.... 

Could remote working and hybrid working, represent the single largest chronic occupational environmental health risk of this century?

While we've been enjoying the flexibility and comfort of working from home, a new, insidious risk is potentially emerging – one that could have profound implications for our long-term health and well-being. This risk is the deteriorating quality of our indoor environment at home

Imagine this: you're working at your home desk, basking in the convenience of avoiding the daily commute, only to discover that your home environment may be quietly undermining your health and productivity. The potential health risks associated with prolonged remote working conditions might represent the single largest chronic environmental health risk of our century.

The surge in remote and hybrid work, catalyzed by the COVID-19 pandemic, has persisted well into 2024, with nearly 49% of desk workers now splitting their time between home and office, and 17% working fully remote. This could translate to around 900 million people globally who are exposed to home environments that were never designed for full-time work.

Achim Haug and Anika Krause

Achim is an ex senior Seimans exec of some two decades with a masters in science who now lives in Thialand and founded Air Gradient, an air quality monitor with a unique approach in the sector. 

That started as a volunteer project to help a school in Northern Thailand monitor the air quality in classrooms during the highly polluted “burning season”. 

From the beginning he put a strong focus on open designs, robust and long-lasting hardware and a strong desire to support people from all around the world with affordable and effective air quality solutions. 

Anika is Air Gradients scientific advisor and lives in Italy. With a  Masters in science and a PhD in philosophy and atmospheric sciences from Cambridge, an expert in air pollution exposure science and data analysis. She has spent several years in research and industry Before joining Air Grandient last year.

AirGradient is currently the only global air quality monitoring company that makes all its hardware design available for free under a Creative Commons CC-BY-SA license. This means that all electronic schematics, firmware code, CAD files are openly available and allow (and encourage) other organizations to use them. They openly publish all their research and algorithms so that others can benefit from the extensive work they are doing.

Its a fascinating approach that cuts against the mainstream and opens up all sorts of potential, risk, challenges and benefits.

At a time when the air quality community and particularly the low cost sensor sector is figuring out the what next, Air Grandient is forging a unique path. And one I was fascinated to discuss.

A conversation with Mazen Jamal

With two decades of experience in the built environment, Mazen's journey in sales has led him from the Middle East to Sweden, where he started working in early prop-tech companies specializing in space utilization, occupancy detection, Indoor Air Quality monitoring, and smart/healthy building analytics.


Since he has conducted business across North America, and Continental Europe, all the way to India, Singapore, Hong Kong, and Japan.

I always think it's interesting talking to people involved in business development, account management and sales it is at the bleeding commercial edge of the sector.

It's close to my heart, but professionals like Mazen are also having conversations daily with the people who count, the customers, in whatever form they take, from C-suite executives to space users.

So it was a real pleasure to talk to Mazen, someone driven to grow the digital smart built environment. And someone who has worked at the coal face in sensor tech, smart buildings and healthy buildings.

Mazen is a straight shooter, and full of insight. Well respected and worth a listen to, in my opinion.

Tom Robins - CEO - Switchee

Founded in 2015 by Adam Fudakowski (CEO) and Ian Napier (CCO), they believed that internet-connected technology could be applied to help social landlords better manage their stock and reduce residents' fuel bills. The solution: a smart thermostat designed specifically for landlords with a dashboard providing real-time data and insights, including some of the environmental conditions within the home.

Following Ian’s death in tragic circumstances in 2019, Adam and the team resolved to continue growing the business in his memory.

In 2020 Tom came into the business and a year later promoted to CEO. Under his stewardship, the business has continued to grow.

Tom has spent his career in scale-up leadership roles; Manufacturing Consulting with Newton, Financial Services Analytics with BIPB, A Board Decision Platform with Board Intelligence and Telecommunications with Community Fibre.

He has been working with the Housing Sector since 2015 and believes in
the power of technology to improve the quality of life for residents while transforming the operating model for providers.

Tom is a real people-focused leader with a track record in building and motivating teams. He also has a technical background, with a master's in chemical engineering from the University of Cambridge.

I have followed Switchee’s journey from its early days and have been fascinated by the passion of the people in it and its mission-led approach to data from the built environment. I was intrigued to chat with Tom about Switchee’s lived experience of translating data in a meaningful way, that they genuinely try to answer important questions in the sector and how that potential can be unlocked.

As more and more of the spaces we occupy provide meaningful data about the environment around us, the lessons companies like Switcee are learning could be valuable insight for others.

Moreover, Tom can paint a picture of what scale-up in this space looks like and the potential it holds.

Dr. Richard Corsi

Dean of the College of Engineering at the University of California, Davis. His team has researched indoor source dynamics, indoor chemistry, and innovative and accessible control technologies for reducing exposure to indoor air pollutants.

During his 24 years as a faculty member at the University of Texas at Austin. He was an endowed research chair and member of the Academy of Distinguished Teachers, and served as Director of a National Science Foundation program on Indoor Environmental Science and Engineering that spawned many successful scholars of indoor air science.

Richard's work has been cited in the New York Times, Washington Post, Los Angeles Times, The Economist, Forbes, National Geographic …….

He is a past President of the Academy of Fellows of the International Society of Indoor Air Quality and Climate (ISIAQ) and past President of the society’s signature conference Indoor Air 2011 in Austin, Texas.

He recently chaired a National Academies committee report on Health Risks of Indoor Exposure to Fine Particulate Matter and Practical Mitigation Solutions. A truly multidisciplinary endevour that has produced a state of the science report that is truly phenomenal. And I think is going to be the go to reference  for some time.

I was really keen to talk to Richard about this report, as his overview of the work is a must listen for anybody working in the built environment, and his ability to bring to life a 270 odd page report in plain english is truly a skill.

I was also keen to talk to one of the people behind the Corsi Rosenthal box, the DIY air cleaner that burst into prominence during the pandemic and turned the sector on its head in many ways.

Ive been looking forward to bringing this conversation to you, I hope you enjoy it as much as I did.

An article recently published in Science, advocating for air quality standards in public buildings, is a fantastic position from many leading voices in the scientific air quality community.

I spent a little bit of time this week talking about it and some of the issues and challenges with the proposition.

Dan Hyde

Dan is a UX strategist, researcher, co-host of the Zero Ambitions Podcast (a podcast about sustainability and the built environment), and co-founder of the magazine that ultimately evolved into Passive House Plus.

At Everything is User Experience, Dan and Alex his co-founder develop the strategy that underpins everything from apps and websites, to bid writing, service design, and corporate sustainability communications. 

Working in the built environment, finance, and healthcare sectors, they carry out practical research that can be turned into simple, strategic packages that enable their clients to create experiences that work for all users.

In a full circle, Dan is a partner in a spin-off of the Zero Ambitions podcast, the Zero Ambitions Partnership offering much of the same strategy advice around UX, but focused specifically on the built environment, with Alex and Jeff Colley, the editor and owner of Passive House Plus and co-host of the podcast of the same name.

I wanted Dan on because he is just a great value to talk to anyway. One of his many skills.

However, beyond the performance gap in IAQ and ventilation in general, we have a significant communications gap, both with users of spaces and the stakeholders who deliver and manage them.

Good UX and design in how we structure strategy, communicate it, and provide ongoing support are everything. This chat scratches at some of these ideas.

This week I ask the question.

If not you then who?

Who is going to measure ventilation in the context of retrofit assessment and other housing scenarios, beyond competent ventilation installers and assessors, and how might that look?

It was a question I raised in response to the publication of the RICS Residential Retrofit Standard.

Have a listen and let me know what you think
