Part I: Radiofrequency Radiation
Design and build homes that minimise RF Radiation from wireless tech.
Cohort based | Mastermind alumni only (for now)
Be among a select group of forward-thinking designers and builders leading the next wave of healthy home innovation.
First live call: 30 October 9am AEDT, 2026
We'll pause in December and Jan with a flexible re-start in Feb, final schedule to be shaped with the group.
''As a residential home builder committed to health, the Radiofrequency Radiation course has been invaluable. It's equipped me with science-based, unbiased knowledge that I can confidently share in fact-based conversation, whether with clients or friends.
The course has deepened my understanding of RF radiation sources, how they interact with building materials and the environment, and how to design effective strategies to prevent RF from entering buildings while mitigating internal sources.''

Why this course is unlike anything else available
This is an industry first offering globally, bridging advanced EMF science with healthy home construction for designed specifically for forward-thinking builders and designers.
Zara brings to the program a rare combination of deep materials research, and advanced EMRS training through the Building Biology Institute in the USA, and extensive industry experience working with award-winning home builders and designers, translating insights into practical frameworks for construction projects.
This course distils step-by-step strategies you can implement on projects, empowering you to collapse time, lead conversations around smart home health, and make a tangible impact in your clients’ lives.
Who the Low EMF Home Design & Construction course is for - and why:
Healthy Building Materials Mastermind alumni: you've already taken steps to improve condensation management and understand the health impacts of building materials, this course is your next opportunity to elevate your building practices and expand your expertise.
By addressing the unseen and often overlooked impact of EMFs, starting with the most prolific of the six types of EMF, radiofrequency radiation, you'll position yourself to deliver even healthier home builds for your clients, filling a critical gap in the healthier building movement.

Building Biologist New Build Consultant
Electromagnetic Radiation Specialist (in-training)
After undergoing 30 doses of radiation during cancer treatment, Zara developed electromagnetic hypersensitivity (EHS), drastically changing how she experienced her home environment.
This personal turning point led to nearly a decade of research, and an unwavering commitment to helping others create homes that truly support health.
In 2023 and 2024, Zara completed two advanced EMF training intensives in the U.S. with world-leading experts, including electricians and electrical engineers, gaining cutting-edge, science-backed knowledge with real-world application.

WHAT TO EXPECT
Radiofrequency Radiation module (part 1)
This first instalment of the Low EMF Home Design & Construction course series focuses on Radiofrequency (RF) Radiation, the most widespread and rapidly evolving form of EMF in our increasingly wireless world. It includes four comprehensive modules covering pre-design, through to post-construction.
-
Understanding RF radiation: grasp the core science behind radiofrequency radiation: what it is, where it comes from, and what the research says about health effects.
-
Initial assessment tools: Explore the pros and cons of entry-level and professional-grade tools for measuring RF exposure in built environments.
-
Practical design & construction strategies: Follow a clear, step-by-step framework to reduce RF exposure through practical design decisions and construction methods you can integrate into your projects right away.
-
Real-world examples from pioneering healthy home builds in the USA.
-
Client education resource: You’ll receive a professionally designed 8-page brochure: Creating a Healthier Home in a Wireless World, to use with clients. It includes practical tips they can implement and positions you as a forward-thinking professional who prioritises their wellbeing.
-
Insights from a world-leading EMF expert in Canada + live Q & A.
-
Module summaries: Each section concludes with a short quiz and summary for easy revision and reference.
Full course series
The Radiofrequency Radiation module is the first in the Low EMF Home Design & Construction course series developed for home designers and builders ready to lead the next era of construction.
There are six EMFs and each behaves, is tested, and mitigated differently. That''s why we're starting with the one of the most prevalent, poorly understood and addressed exposure types in home building. construction.
Future instalments (to be delivered in 2026) will address AC magnetic fields, AC electric fields, which are vital to address pre, during and post construction in a Low EMF build, in addition to RF.
DC magnetic fields & geopathic stress, DC electric fields, will be explored briefly as needed, as well as strategies to reduce the likelihood of Microsurgery Electrical Pollution (a.k.a. dirty electricity) and do spot and address checks post construction, with content delivered in logical, application based stages.
Our approach is proactive and preventative, by implementing these strategies early, you can minimise or avoid the need to address complex issues later.
The RF radiation course is one of the most comprehensive in the series and it is your foundation. Not all modules will be this extensive, the level of depth and technical guidance for home designers and builders varies for each EMF, for instance, AC electric and AC magnetic will be addressed together, given they overlap during construction stages - but they require different mitigation strategies.
You'll get first access to the full course series at a reduced rate as a founding participant if you decide to continue on the full pathway (no. Your feedback will help shape how we deliver them.
Move beyond traditional standards -
design for long term health
Traditional electrical standards focus on preventing immediate dangers like shock, fire, and injury, but they overlook the long-term health effects of electromagnetic fields.
As home designers and builders, you have the opportunity to go beyond traditional standards and lead the way in creating healthier,safer homes
Imagine a future where every home is designed as a sanctuary for the body to rest and repair.
Reducing radiofrequency radiation exposure is an opportunity for industry leaders to create homes that truly prioritise health.
By the end of this course, you'll understand how to design and build low EMF homes, reduce health risks for occupants, and differentiate your projects in the market.
Please note:
This is the last time this course will be offered at this price. Given the scope, depth, and rapidly evolving nature of this field, and the ongoing investment we're making in real-world insights, testing, and expert integration. This is a living, breathing course that reflects not just best practice, but what's unfolding now on high end healthy home builds in the USA. It's built for early pioneers who want to stay ahead of the curve.
🎯 This is a focused cohort —
designed for a select group of designers and builders committed to pushing the industry forward.
You’ll gain access to live support, a real-world framework, and a chance to be at the forefront of the healthy home movement.
Spaces are limited

TIMING & CALL STRUCTURE
When and how it runs
This is the only live cohort of the Radiofrequency Radiation module we’ll be running in 2025.
Live implementation calls:
📅 Held monthly on a Thursday (9am AEDT/4pm) in the last week's of October, November, and Jan / Feb, or Feb / March depending on group consensus.
Replays will be available, but live attendance is encouraged for Q&A and tailored support, and required to meet the full Low EMF Home Design & Construction Course certificate of completion requirements.

Think of EMFs as invisible pollutants
Just like air and water pollution. With the right knowledge and tools, we can create safer environments.
Start with RF Radiation — one of the most pervasive EMFs affecting modern homes —and learn actionable steps to address it: from measurement, to pre-design, design and construction.

Learning outcomes
The course is designed to empower designers and builders with the knowledge and practical steps to implement low EMF design and construction practices.
It provides comprehensive insights and strategies but does not certify participants as EMF testing professionals. It is ideal for those who do not want to become EMF testing technicians but need actionable steps they can implement using blueprints created specifically for this purpose.
