HQE IN-USE
An operational framework for sustainable building performance
HQE In-Use is an international certification framework dedicated to the environmental and energy performance of buildings in operation. It focuses on how buildings are actually used, managed, and maintained over time, rather than on design intent alone.
HQE In-Use provides a structured methodology to assess, monitor, and improve operational performance, making it a powerful tool for asset managers, building owners, and operators.
A certification focused on real-use conditions
Unlike design-based certifications, HQE In-Use is grounded in real operational data and everyday practices. It evaluates buildings as they function in reality, taking into account occupancy, systems operation, maintenance strategies, and management processes.
This approach makes HQE In-Use particularly relevant for existing buildings, portfolios in operation, and assets seeking continuous performance improvement.
From operational assessment to continuous improvement
HQE In-Use is not a one-time assessment. It is designed to support long-term performance management by identifying gaps, prioritizing actions, and structuring improvement plans.
The framework covers key operational themes such as:
- energy and resource consumption in operation
- greenhouse gas emissions and carbon reduction
- indoor environmental quality and occupant comfort
- building management and maintenance practices
- monitoring, data use and performance tracking
By addressing these dimensions together, HQE In-Use helps transform operational challenges into measurable performance gains.
Our role as technical and strategic advisor
We support building owners, asset managers, and operators throughout HQE In-Use certification processes, acting as an independent technical and strategic advisor.
Our services include:
- operational performance assessments
- HQE In-Use strategy definition
- technical advisory and coordination
- support with data collection and documentation
- performance monitoring and follow-up over time
Our approach ensures that HQE In-Use is integrated into day-to-day building management and aligned with long-term asset strategies.
A framework adapted to international contexts
HQE In-Use is designed to be adaptable to a wide range of building types, climates, and operational contexts. This flexibility allows it to be implemented on international portfolios and in diverse regulatory environments.
By aligning HQE In-Use requirements with local operational realities and international best practices, we help project teams deploy robust and credible certification strategies across different markets.
Why adopt HQE In-Use?
- To assess and improve real operational performance
- To reduce energy use and carbon emissions in operation
- To enhance occupant comfort and building management quality
- To structure continuous improvement strategies
- To strengthen asset value and long-term resilience
