Energy Simulations of a Building Insulated with a Hemp-Lime Composite with Different Wall and Node Variants

open access: yesEnergies, 2022
Thermal bridges constitute a significant share in the overall heat losses through building partitions. This is an important issue not only in traditional but also ecological buildings, where the load-bearing structure is often a wooden frame.

Modelling Of The Thermal Behavior Of Walls And Floors In Contact With The Ground [PDF]

open access: yes, 2012
One of the most complex configuration to model in detail, both in the dynamic simulation of buildings and in the analytical quasi steady-state calculations, is the thermal dispersion through the walls and the floor in contact with the ground. The problem

Patents Analysis of Thermal Bridges in Slab Fronts and Their Effect on Energy Demand

open access: yesEnergies, 2018
Nowadays, the building sector is one of the main sources emitting pollutant gases to the atmosphere due to its deficient energy behaviour. Among the elements of the envelope, the thermal bridges are where the heat losses and gains mainly occur, depending
