Overview
ISO/PAS 50010:2023 - Energy management and energy savings: Guidance for net zero energy in operations using an ISO 50001 energy management system - is a Publicly Available Specification from ISO that explains how an existing energy management system (EnMS) in accordance with ISO 50001:2018 can be used and enhanced to achieve net zero energy (NZE) in operations. The document focuses on operational and maintenance measures, the integration of renewable energy, and planning for NZE/NZC (net zero carbon) outcomes. It is a guidance document (first edition, 2023) and does not prescribe technology, design or construction details nor specific technical specifications for renewable systems due to regional variation.
Key Topics
- EnMS implementation for NZE
- Setting scope and boundaries for NZE targets
- Developing NZE plans and NZE policy within an EnMS
- Defining energy and carbon-emission goals tied to continual improvement
- Performance measurement
- Selection of appropriate energy performance indicators (EnPIs)
- Data collection planning and methods
- Accounting for year-to-year variability (e.g., weather, renewable output)
- Operations and maintenance (O&M)
- Recommendations for improving O&M practices to reduce operational energy use
- Use of control technology and demand response to align loads with renewables
- Renewable energy integration
- On-site and off-site renewable considerations, grid interaction and procurement
- Use of renewable energy credits and grid-based renewable resources
- Supporting materials
- Informative annexes on the relationship between NZE design/construction and operation, and an NZE implementation overview
Applications
ISO/PAS 50010:2023 is practical for organizations seeking to align energy management with ambitious decarbonization targets. Typical users include:
- Energy managers and EnMS implementers
- Facility and building operations managers
- Sustainability and corporate carbon teams
- Energy service companies (ESCOs) and consultants
- Policy makers and public sector bodies setting NZE pathways
Use cases:
- Establishing NZE targets within an ISO 50001 EnMS
- Integrating renewable energy procurement and demand response into operational strategies
- Developing EnPIs and data plans to demonstrate progress toward NZE/NZC
Related Standards
This guidance enables organizations to harmonize NZE claims, set quantifiable targets, and use a structured EnMS approach to progress toward net zero energy and net zero carbon objectives.
