HQE Performance 20th June 2013
Results of the HQE Performance project
HQE Performance, testing
Experiment Life Cycle Analysis (LCA) methods as tools for designing and evaluating energy efficient buildings.
Objectives:
Test an evaluation framework.
Provide usable reference scales for stakeholders.
Develop new skills for the French building sector.

An improved analysis framework: Implementing rules HQE Performance
New contributors
Better tools
LCA building tools
Effinergie - Ecomobilité
Implementation guide
A better support for stakeholders
New environmental data • FDES : 1125 FDES in INIES database
• Use of PEP for equipment
• More buildings (less modelled typologies)
More precised and reinforced results
To understand better the influence of some parameters

A potential of improvement
up to 30%?
What is the impact
of integrating car
parks into the
infrastructure? Of
the seismic zone?
Of the foundation
type?
For 6 buildings more than
10% of the impacts come
from the photovoltaïc
panels
Among these, 2 > 20%
What is the impact of
construction system ? Of
the flooring? Of the
climate zone?

Contributor « Products and materials for construction »
Does the building size (total net
floor area and number or storey)
influence on the unit impacts?
YES
The total net floor area affects
the indicator « Non renewable
energy consumption »
Does the foundation type
influence the unit impacts?
YES
The number of storey affects
the indicator « Climate
change »
NO
Do the kind and size of the car
parks influence the structural work
?
YES
Upon the indicator « Non-renewable
energy consumption »
YES
Upon the indicator « Climate
change »

CONCLUSION
26
Results set priorities.
Results lead us when looking for solutions.
A common and methodical evaluation framework.
An effective learning.
Data and tools more experienced.
Prospects:
Focus on the key points.
Make a successful transition to the EN 15804 standard.
Thanks for your attention
