Embodied energy

Climate responsive design ensures thermal comfort in buildings without using excessive energy for heating and cooling. This study explores how the relationship between the quantity of north (equator) facing window area, the quantity of thermal capacity and the distribution of thermal capacity in a space can improve comfort and energy efficiency in residential buildings in Australia, and optimise lifetime CO2-e emissions. The study concludes that thermal capacity can improve the thermal efficiency of the simulated structure, primarily through its influence on annual cooling loads.

El sector de la edificación en la UE representa entorno a un 40 % del consumo de energía final, y en España, cuando se internalice la demanda energética de refrigeración, alcanzará porcentajes del mismo orden. Por ello se están articulando una serie de me

The paper deals with a complete procedure for the calculation of material embodied energy inthe building sector using a Life Cycle Assessment (LCA) approach; the calculation of embodied energy for building material and components during the design phase takes into account both material durability and frequency of maintenance interventions. As a case study an evaluation of embodied energy for three different types of external walls is reported: external insulation coated, single stratum and multi strata.
