Why ALDREN?
• only about 1-2% of the building stock is renovated each year;
• only around 15 % of building refurbishments
incorporate significant energy efficiency improvements.
energy savings are not the trigger for renovationSome reasons:
• no sufficient financial interest;
• absence of a holistic strategy;
• lack of communication between the different stakeholders
• (building professionals, building owners, finance).
Communicate all benefits of energy renovation
and not only the energy savings:
The ALDREN common language

CONSEQUENCES
modest gains in work performance
(staff costs) can deliver
significant financial benefits
There is a need for:
- European Health + well-being indicator
- link between this indicator
- and financial benefits
Example: Cost structure in an office building
economic interest is more in the increase of
productivity (90%) than in energy (1%)

Value Market value (Investment) worth
Example:
how qualitative assessment of “performance”
is translated into a financial value(Part of mandatory method for asset valuation for bank loan secure in Slovakia).
Mandatory method for asset valuation for bank loan secure in Slovakia.
Example Location: Assessor has to choose between classes:
The mortgage / market value is then calculated by multiplying:
Localisation Differentiation coefficient X technical value
The technical value are the construction costs for similar new building with
depreciation by age of the given building
The class Value per class

II. 1,600

+ guidelines
ALDREN provide guidelines
for energy performance
(e.g. energy -, maintenance costs, comfort)

Résume
• Energy savings alone do not trigger building renovation
➢ ALDREN offers an holistic approach on energy
(e.g. linking it with health and well being, finance)
A methodology to stimulate the increase of
renovation rate and quality has been created
But…
• Communication between the different stakeholders
involved in building renovation is needed
➢ ALDREN express building performance in reliable,
transparent indicators and
translate them into financial asset

…nothing will happen…
…without a strong
strategic partnership for
market uptake
![Page 14: Presentación de PowerPoint · (e.g. energy -, maintenance costs, comfort) 12 Résume • Energy savings alone do not trigger building renovation ALDREN offers an holistic approach](https://reader034.fdocuments.net/reader034/viewer/2022050504/5f967f68210313505f5293e2/html5/thumbnails/14.jpg)

Potential partnerships(even for modular market uptake)
• Skilled professionals
to train / certify experts to apply the ALDREN method
e.g. REHVA, CEN-CE project (www.cen-ce.eu)
Thank you for your attention
• Voluntary environmental certification schemes
to take over ALDREN indicators and methods (e.g. HQE, DGNB, BREEAM)
• Financial institutes
to include ALDREN in asset valuation, linking interest to building performance
• Asset managers, building owners
to include ALDREN methodologies in decision making/taking process
• European Commission
to reference ALDREN as quality benchmark for EU funding
(e.g. as voluntary common certification scheme)
