The LT ready concept describes low-temperature capability readiness of buildings and municipalities - for German and European building policy

Fernwärmeleitung

This study explores the benefits of lower flow temperatures water for different heating technologies, focusing on heat pumps and district heating, the barriers to reducing flow temperatures in heating systems and examines the concept of LT readiness and its limitations by discussing how to make a building LT ready (low temperature ready).

This concept will be explored in two case studies. The first case study looks at LT readiness from the perspective of individual buildings. For four typical German buildings, we calculate the required steps will be calculated to make them LT ready and propose a ‘procedure’ to renovate them. The second case study looks at a German city that plans to develop a low temperature district heating system and make 400 buildings LT ready. Last the study explores how LT readiness can be implemented through a range of policy tools and provides a short inventory of policies that, including European policies, address low temperature heating and LT readiness.
