Assessing solar integration potential in heritage contexts
INTRODUCTION
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.
