From city to country living and modest-sized homes to sprawling mansions, Elexana understands the similarities and differences between the various power demands, alternative energy applications, and their electromagnetic environments.
For those embarking upon a new home construction or renovation, ensuring your family’s wellness by planning for minimal exposure to human-engineered electromagnetic field radiation is essential.
The residual benefits of reduced EMI are lowered electric bills, improved electronic function, plus a longer lifespan for all appliances, equipment, and electronic devices.
Elexana consults on the entire electrical system and the system ground, the placement of the power vault, switchgear, wiring, electrical panels, indoor and outdoor lighting design, surveillance systems, furniture design consulting, interior decoration, and more.
We additionally advise on signal-to-line noise (sometimes termed “dirty electricity”) and appropriate RF remediation.
Our experience ranges from Manhattan penthouse apartments to mansion construction in New York, Connecticut, Hawaii, California, Georgia, Florida, Texas, and anywhere else in America, where we are called upon.
ALARA EMF-EMI New Construction Design is a leading-edge, health-conscious approach to building that integrates:
Science-backed risk reduction.
Electromagnetic engineering expertise.
Architectural foresight
to create electromagnetically safe and functional spaces.
Creating an ALARA EMF-EMI Electromagnetic Environment for a new building design project requires careful planning and attention to detail. This article is meant to help you get started. There are many more things you can do that are not listed here. Essential factors to consider are:
Site Selection: Choose locations away from primary EMF sources (e.g., power lines, cell towers, substations).
Electrical Design: Plan wiring layouts to minimize electromagnetic fields, using shielded cables and proper grounding. You can do many more things here, but this is a good start for an article.
HVAC and Lighting Systems: Select equipment with low EMF emissions; avoid unnecessary wireless controls.
Internal Networks: Prioritize wired (Ethernet or fiber optic) connections over Wi-Fi; use shielded network cables.
Room Zoning: Designate low-EMF zones, particularly for bedrooms, offices, or sensitive equipment areas.
Testing and Verification: Conduct baseline EMF measurements before occupancy and adjust shielding or grounding as needed.
Occupant Education: Provide building users with guidelines on minimizing EMF from personal devices and equipment.
Building Materials: In rare cases, you may need to block external EMFs by using shielding materials such as conductive paints, metal mesh, or RF-mitigating window films. This should generally be considered a last resort for extreme conditions. I am not a fan of using these techniques, especially if care was not taken in making a good site selection.
Here’s a complete checklist and design guide for architects and engineers working on low-EMF building projects:
Site Evaluation
Conduct a preliminary EMF survey of candidate sites
Assess proximity to external EMF sources (cell towers, high-voltage lines, substations)
Choose locations with naturally lower background EMF levels
Architectural Design
In rare cases, you can integrate shielding into walls, windows, and roofs using conductive materials.
Design floor plans to create protected low-EMF zones, especially in sleeping and working areas.
Use natural building materials where possible to reduce unnecessary radio frequency signal reflections.
Electrical and Cabling Layout
Implement radial wiring systems to reduce loop areas.
Use shielded and twisted-pair cables for all electrical and data circuits.
Install demand switches to cut circuit power when not in use (especially in bedrooms).
Ensure rigorous grounding and bonding across the entire system.

HVAC and Building Systems
Select low-EMF equipment (motors, compressors, thermostats).
Avoid Wi-Fi-enabled or Bluetooth-connected HVAC controls where wired alternatives exist.
Route building management system (BMS) controls using shielded cables.
Networking and Communications
1. Minimize or eliminate WiFi, DECT phones, and other wireless systems.
2. Provide shielded dedicated rooms for unavoidable wireless equipment.
3. Prioritize using hardwired data connections like Ethernet or fiber optics.
Testing, Commissioning, and Certification
Perform detailed EMF measurements after system installation.
Identify and mitigate unexpected sources (e.g., appliances, transformers, dimmers).
Obtain third-party verification or certification of compliance with low-EMF standards.
Documentation and Occupant Guidelines
Provide detailed as-built documentation noting low-EMF features.
Supply users with practical guidelines for minimizing in-use EMF (e.g., device placement, power management).
Offer periodic EMF reassessment to ensure long-term performance.
Additionally, here’s a focused checklist for creating a low-EMI lighting system for a new building:
Lighting System Design
Select lighting fixtures tested for low EMI emissions (check manufacturer's EMI ratings).
Avoid dimmer switches that generate high-frequency noise; opt for filtered or low-EMI dimmers.
Use LED drivers with proper shielding and filters, as poorly designed drivers can be primary EMI sources.
Place lighting circuits in shielded conduits where necessary, especially near sensitive equipment zones.
Separate lighting circuits from data and sensitive electronic circuits to reduce coupling and interference.
Ensure all lighting circuits are properly grounded and bonded to minimize stray currents.
Consider using DC-based or low-voltage lighting systems in critical low-EMI zones.
Test lighting systems post-installation with EMI detectors to confirm compliance with design targets.
