'Are smart homes, healthier homes?'
Webinar recording
What home designers and builders
need to know about wireless tech
Â
With Zara D'Cotta
Electromagnetic Radiation Specialist
Building Biology New Build Consultant
Founder, The Healthy Home
A bold and necessary conversation with Zara D’Cotta,
Building Biology New Build Consultant, Electromagnetic Radiation Specialist,
Keynote Speaker & Founder of The Healthy Home,
for builders and designers who are ready to
question the status quo and lead the next evolution
of truly healthy home design and construction.
Duration: 1 hr 11 minute recording of a live webinar hosted in June 2025, updated with latest 2026 research references.Â
Who it’s for: Builders, designers, & construction professionals actively delivering residential building projects, who want to lead the industry in creating homes that truly support health and wellbeing.
Â
Why this matters...
Smart homes are on the rise, but are they truly healthy? As more homes adopt wireless devices, automation systems, and remote monitoring, it's time to ask:
• Are there health implications of smart home technology?
• Could convenience be coming at the cost of long-term wellbeing?
In this session you'll also hear insights from an innovation engineer who shares why their office has no WiFi, and the difference the team notices. When a company known for their expertise in building science and airtightness, makes that call, it's worth paying attention to.Â
About Zara D'Cotta
Zara D’Cotta is a Building Biology New Build Consultant, Electromagnetic Radiation Specialist (EMRS), Keynote Speaker, and Founder of The Healthy Home.
After undergoing 30 doses of radiation during cancer treatment, Zara developed electromagnetic hypersensitivity (EHS), which drastically changed how she experienced her home environment.
When Zara raised her experience with her neurologist she was dismissed and offered antidepressants. She wasn't alone, this is the experience of people all over the world who are being dismissed by the professionals meant to help them.
It's why she spent years in independent research, trained under leading EMRS experts in the US, and why she created this session, so that the professionals building our homes understand what medical systems and the construction industry is not yet equipped to acknowledge.
Between 2023 and 2025, Zara completed advanced hands-on training in the U.S. under leading EMRS experts, including electricians and electrical engineers. She was certified in 2025 and continues ongoing professional development and knowledge sharing with her U.S. EMRS peer network.
She works with builders, designers, and architects to help them reduce health risks in homes, with a focus on electromagnetic fields, materials, and mould prevention.
Zara is trusted by forward-thinking, health-focused home designers and builders.
She has delivered presentations for the Australian Institute of Architects, Master Builders Australia, Building Designers Association of Australia, Association of Professional Builders, and the Sustainable Builders Alliance.
