ADVANCED ENVIRONMENTAL EXPOSURE EDUCATION

The Next Evolution in Indoor Environmental Health Education

The built environment is more than a structure. It is a dynamic system where moisture, airflow, particles, microorganisms, HVAC operation, building materials, reservoirs and occupant activity can influence environmental exposure.

INTRODUCING

The Biological Exposure System™

A systematic framework for evaluating how environmental contaminants originate, persist, become entrained, move through occupied environments, deposit onto surfaces, become re-entrained and ultimately contribute to potential occupant exposure.

THE EXPOSURE-BASED APPROACH

Go Beyond Finding Contamination. Understand How Exposure Happens.

CEEP™ training expands the environmental professional's perspective from isolated findings to the relationships between reservoirs, building systems, airborne transport, deposition, re-entrainment, environmental intervention and verification.

Designed for the Next Generation of Environmental Professionals

PEPN-HEART™ is designed for inspectors, indoor environmental professionals, remediators, HVAC professionals, restoration contractors, industrial hygienists, healthcare professionals, building scientists, and anyone seeking a comprehensive understanding of how buildings influence human health. By combining building science, environmental microbiology, aerosol science, exposure assessment, and evidence-based intervention strategies, the PEPN-HEART™ Foundations Course provides a modern framework for advancing the environmental health profession.

SCIENCE • EXPOSURE • VERIFICATION

The PEPN-HEART™ Protocol

A specialized scientific framework for environmental health intervention.

The PEPN-HEART™ Protocol is a specialized scientific framework established to define environmental health intervention as an independent professional discipline.

A DIFFERENT APPROACH

Unlike traditional remediation that focuses primarily on structural repairs, this system prioritizes the evaluation and reduction of inhalation-based biological hazards within occupied buildings.

THE SCIENTIFIC FOUNDATION

Built Upon Interdisciplinary Science

Its foundation is built upon decades of interdisciplinary global research, integrating environmental science, building science, exposure science, medicine, and public health.

Environmental Microbiology
Aerosol Science
Exposure Assessment
Inhalation Dynamics
Building Science
Occupational Health
Environmental Medicine
Epidemiology & Public Health
DATA-DRIVEN ENVIRONMENTAL HEALTH

Measure the Exposure.
Measure the Intervention.

The PEPN-HEART™ framework utilizes objective environmental data to characterize biologically active exposure burdens and evaluate whether intervention efforts have meaningfully reduced exposure pathways within the built environment.

THE PEPN-HEART™ QUESTION
Did the intervention measurably reduce the biological exposure burden?
THE PEPN-HEART™ FRAMEWORK
CHARACTERIZE → IDENTIFY → INTERVENE → REDUCE → VERIFY → STABILIZE

From Damage-Focused Remediation to Exposure-Focused Environmental Health

PEPN-HEART™ evaluates the indoor environment through the lens of human exposure—using environmental science, objective measurement, and verification to determine whether meaningful reductions in biological exposure pathways have been achieved.

Why PEPN-HEART™ Is Different

PEPN-HEART™ was designed around a simple principle: environmental health claims should be supported by objective evidence. Instead of relying solely on visual observations or assumptions, professionals are taught to collect, interpret, and compare measurable environmental data before and after intervention. This evidence-based approach allows practitioners to document meaningful reductions in biological exposure burden and demonstrate the effectiveness of their work using scientific verification rather than opinion.

We believe environmental professionals should be able to answer one fundamental question with confidence: "Did the intervention measurably reduce the biological exposure burden?" PEPN-HEART™ provides the framework, methodology, and verification tools to answer that question using data.
