Xplorion – a pioneering multi family building with climate friendly solutions

,
Xplorion in Lund is a world-class innovation project for those who want to live sustainable. The building focuses on climate-smart solutions that are highly present in the tenant’s everyday life. Two solutions within COOL DH are demonstrated in Xplorion: Local energy solution with heat pump hot water topping and an innovative three-pipe solution.
The image shows how the installation of the LTDH-service pipes in Osterby are close to the users' buildings in order to reduce the length of the network and consequently the heat losses.

From traditional DH to LTDH in Østerby

, , , ,
A new low-temperature network has been designed to upgrade the old and obsolete traditional district heating-network in Høje-Taastrup. This report provides information about the final design and the implementation of the low-temperature district heating network and can be used as a guideline of the installation process for future similar projects.
