Latvijas Nacionālās bibliotēkas saules paneļu parks
As part of the project at the National Library of Latvia, a complex solar power plant was constructed, adhering to rigorous architectural, operational and safety requirements.
The design bureau ‘BALTS UN MELNS’ developed the technical solutions and coordinated the project, adapting the layout of the solar panels to the building's existing structure and infrastructure.
Given the complex roof geometry of the ‘Castle of Light’ and the building's public significance, particular attention during the design process was paid to optimising the panel layout, load calculations, fixing solutions and integration into the existing engineering systems. Assessments were carried out on the roof's load-bearing capacity, power supply connections, lightning protection and compliance with fire safety regulations.
The solutions developed by ‘BALTS UN MELNS’ ensure the efficient operation of the solar panel system, whilst preserving the building's architectural character and ensuring its daily operations remain undisturbed.
This project demonstrates the experience of ‘BALTS UN MELNS’ in developing complex energy efficiency projects for prominent public buildings, where precise adaptation of technical solutions to existing infrastructure and adherence to high construction standards are paramount.
