THIS DOCUMENT PRESENTS A BLUEPRINT FROM THE CALECHE HUB PROJECT ON HOW TO INTEGRATE PHOTOVOLTAIC SYSTEMS INTO A UNESCO-LISTED HISTORIC CITY, USING LA CHAUX-DE-FONDS AS A CASE STUDY.
Brief Summary
The report addresses the challenge of combining heritage preservation with energy transition. It proposes a spatial strategy based on heritage sensitivity and visibility, allowing differentiated rules instead of uniform restrictions.
The study shows that most solar potential lies outside highly sensitive areas, making large-scale PV deployment possible without harming key heritage zones.
It concludes with practical recommendations for municipalities, heritage authorities, and investors to support a balanced and effective solar integration.INTRODUCTION

Explore real-life examples of historical buildings retrofits in HIBERATLAS.
This web database gathers best-practice examples of how historic buildings can be renovated to achieve high levels of energy
efficiency while protecting their heritage value.Each example documents the renovation process and aim of the retrofit, building description and heritage assessment, retrofit
solutions (both passive and active), and evaluation of the intervention. You can filter the database according to location, building
type, type of retrofit solutions, renewable energy system, and type of evaluation performed.The database development has been funded by the Interreg Alpine Space project “ATLAS” and Task 59 of IEA Solar Heating and
Cooling programme.
Energy efficiency measures may trigger impacts on different parts or functions of the historic building, beyond their initial purpose. Some examples: moisture transport or loss of indoor environment quality.
It is therefore critical to identify these potential consequences before deciding on a specific set of energy improvement measures.
In this blueprint, you will see:
+ Why and how to consider Indoor Environmental Quality (IEQ) in your decision process
+ Concrete examples of chains of consequence triggered by different energy efficiency measures, and related mitigation actions
Heritage renovation is not only a technical and energy-related challenge, but also a socio-cultural one, as historic buildings carry cultural, historical, social and symbolic values shaped by local identities, practices and regulations. Ignoring these dimensions can create resistance, stakeholder conflicts and renovation strategies that are technically effective but socially or culturally unacceptable.
Brief Summary
Together, these blueprints present a complementary approach to heritage renovation, from identifying socio-cultural and heritage values, to analysing conflicts between cultural, social, economic and environmental objectives, and finally translating these assessments into concrete decision-making. They provide a structured framework to support more transparent, balanced and context-sensitive renovation strategies by integrating stakeholder perspectives, value trade-offs and multi-criteria arbitration into the planning process.

Successful heritage renovation depends on meaningful stakeholder engagement. Identifying and involving the right stakeholders early in the process helps capture diverse perspectives, make use of local knowledge, and build support for renovation decisions.
This resource provides practical guidance for planning and delivering effective stakeholder engagement throughout the project lifecycle, to improve collaboration across heritage, engineering, and construction professionals.
Effective collaboration is essential for the sustainable renovation of historic buildings. Different disciplines and countries often use the same technical terms with different meanings, creating barriers to communication and decision-making.
The CALECHE lexicon is a multilingual glossary which establishes a common language to improve collaboration across heritage, engineering, and construction professionals.
To foster better collaboration and improve consensus-building throughout heritage renovation projects, stakeholder engagement
processes must be turned into participatory approaches where stakeholders are active.In CALECHE, various interactive approaches were designed to foster engagement at the four pilot sites. This resource
introduce the interactive tools and approaches used to foster two-way dialogue between project teams and stakeholders and to
support co-design.
A renovation process aims, among others, to reduce the energy demand of the building, and the associated carbon emissions.
However, the renovation process itself has an environmental impact related to the new material that is manufactured, transported and added to the buliding, the machinery used, etc.
Accounting for ciruclarity in building renovation therefore implies to consider the resources used to perform the renovation, and the impact and reversibility of the energy efficiency measures on the building itself.
In this blueprint, you will learn:
+ The circularity principles and the associated strategies for energy efficient renovation
+ How a Life Cycle Assessment method can help estimate the balance between added materials and reduced energy demand in building operation
+ The illustration of this LCA approach on a practical case of historic building renovationHeritage Building Information Modelling (HBIM), as a single interoperable digital system, enables to integrate and interpret a wide variety of data about the building, from surveying to historical knowledge, conservation status analysis and information management.
In CALECHE, an HBIM model was developed both as a three-dimensional representation of the building, and as structured information to be used directly by the Decision Support System aiming at historical renovation project design.
In this blueprint, you will learn:
+ how the University of Naples Federico II and STRESS developed an HBIM for the building of Villa Materazzo in Napoli
+ how they designed the HBIM-to-DSS workflows
+ Their main insights and recommendations drawned from this workINTRODUCTION

This web database gathers examples of retrofit solutions implemented in real-life, covering both building envelope and active systems:
+ Each solution is described and evaluated in terms of energy performance, heritage compatibility, comfort, circularity and cost.
+ You can apply various filters to identify examples relevant to your own context.
