INTRODUCTION

The Level 1 Award: Near Zero Energy Building (NZEB Plumbing) for Plumbers is designed to introduce qualified or early-career plumbers to the core principles and practical skills needed to work on NZEB-compliant buildings. The course builds a foundational understanding of energy efficiency, renewable technologies, and sustainable plumbing systems, starting trom the environmental purpose of NZEB and progressing through compliance tools like DEAP, building physics, and energy services integration.

Delivered over seven modules (one day each), the programme combines classroom learning with hands-on activities to connect theory to real-world practice. Learners gain practical insights into how plumbing affects building performance, how to work alongside other trades, and how to uphold the standards required for NZEB projects. No prior NZEB experience is required, making it ideal for plumbers seeking to transition into greener, future-focused roles within the built environment.

MODULE OVERVIEW

IDENTIFY THE PURPOSE OF NZEB
Introduces the environmental need for NZEB in plumbing and construction, Explains climate challenges, energy usage, and emissions in buildings. Learners understand how NZEB supports energy efficiency and modern plumbing roles.

THE NZEB CONCEPTS & PRINCIPLES
Covers the fundamentals of NZEB – reducing energy demand and increasing renewable input. Explains passive and active energy design, and system efficiency in plumbing. Introduces key NZEB metrics relevant to plumbing services.

DEMONSTRATING NZEB COMPLIANCE USING DEAP
Introduces the DEAP tool tor assessing energy pertormance in homes, Shows how plumbing systems impact DEAP scoring and compliance, Practical guidance on interpreting plumbing-related DEAP outputs.

BUILDING PHYSICS & ENERGY PERFORMANCE
Explains how heat transfer, moisture, and ventilation affect energy loss. Connects plumbing decisions to 25 thermal efficiency and occupant comfort. Hands-on examples of condensation control, insulation, and pipe placement.

BUILDING FABRIC
Focuses on walls, roots, and floors as part of the energy envelope. Highlights the plumber’s responsibility in avoiding thermal bridging and air leaks. Learners understand how improper installation affects energy efficiency.

BUILDING ENERGY SERVICES
Introduces heating systems, hot water storage, heat pumps, and controls. Explores how plumbing integrates with sustainable building systems. Covers low-Temperature heating and zoning strategies.

COMMUNICATION & INTERFACING
Teaches communication with other trades to uphold NZEB principles. Covers ho plumbing interfaces wit electrical, mechanical, and digitai systems. Stresses teamwork, documentation, and accurate reporting.

PROGRESSION OPPORTUNITIES

Upon successful completion, learners may:

01: Learners will understand the meaning, importance, and core principles of NZEB, and how modern plumbing contributes to energy efficiency, sustainability, and regulatory compliance.

02: Learners can apply NZEB principles in practical plumbing tasks, interpret compliance data, and communicate effectively with other construction professionals.

03: Learners will take responsibility for safe, sustainable plumbing practices, knowing when to seek guidance and how the their work supports whole-building energy efficiency.
