Low Emission Design Near Field Awareness
LEDNA
LEDNA (Low Emission Design Near Field Awareness) is EFEIA’s design-based approach to electromagnetic field exposure reduction. Unlike traditional shielding methods that react to existing exposure, LEDNA prevents problematic exposure through strategic planning at three levels: infrastructure design, space planning, and daily choices.
The principle is simple: distance and design matter more than barriers.
Why LEDNA?
We've been doing this backwards
For decades, the approach has been reactive: wait for symptoms, measure exposure, install shielding, fix problems after they appear.
LEDNA flips this by building electromagnetic hygiene into spaces from the beginning, designing low-emission environments instead of defending against high-emission ones.
LEDNA isn't another protocol to follow. It's a design standard that makes electromagnetic hygiene the default, not the exception.
Old Way vs. New Way
The difference between reacting to problems and preventing them
The Old Way
React and Shield
Symptoms appear, so you measure, buy shielding products, and remediate after the fact. EMF becomes something you constantly fight against with barriers and fixes.
The LEDNA Way
Design and Prevent
Start with low emissions and design spaces where exposure stays minimal from day one, building environments that don’t need fixing because the problem never develops.
Six Core Principles
What drives LEDNA
01
Design First
Electromagnetic hygiene belongs in the first draft, whether you’re designing a building, a product, or a city block. Low emissions start at the blueprint stage.
02
Focus on Proximity
The biggest exposures happen where people spend their time in bedrooms, offices, and schools. Near-field environments matter most.
03
Prevent, Don’t Fix
The best shielding is no shielding because when you design spaces that don’t generate high emissions in the first place, prevention beats remediation.
04
Think Systems
Electromagnetic hygiene works as a whole system that includes wiring, materials, device placement, and infrastructure optimized together.
05
Follow the Science
Design choices come from biological research, exposure data, and measurable health outcomes where evidence drives decisions.
06
Build Sustainably
Low-emission design overlaps with energy efficiency, creating environments that are healthier for both people and the planet.
Where LEDNA Works
Real contexts, real impact
Why This Matters
The case for doing it right from the start
EMF exposure never stops in modern environments, and reactive fixes can’t keep up
More people recognize EMF sensitivity and biological effects every year
Prevention costs less than remediation because design beats damage control
Wireless technology keeps expanding, which means old approaches won’t work
How It Works
Five steps to low-emission design
1.
Understand Near-Field Environments
Learn what creates exposure by studying biological effects research and mapping where people actually spend their time.
2.
Build It In From Day One
Low emissions become a design requirement from the first sketch, built in rather than optional or added later.
3.
Prioritize High-Occupancy Spaces
Focus on bedrooms first, then offices, schools, and anywhere people spend hours daily where the impact matters most.
4.
Measure and Verify
Test that low-emission goals were actually met using objective tools to verify the design works as intended.
5.
Share What Works
Spread knowledge to architects, engineers, and designers to make LEDNA standard practice rather than niche expertise.

LEDNA works for architects, engineers, designers, developers, and anyone building spaces where people live and work by designing electromagnetic hygiene in instead of adding it on.
