Combining building thermal simulation methods and LCA methods
نویسنده
چکیده
This paper describes recent efforts made by the Danish Building Research Institute regarding the integration of a life cycle assessment (LCA) method into a whole building hygro-thermal simulation tool. The motivation for the work is that the increased requirements to the energy performance of buildings (as expressed in EU Directive 2002/91/EC), may in the future be supplemented by requirements to the environmental impact of buildings. This can be seen by the fact that EU recently has given CEN mandate to prepare standards for environmental assessment of buildings (CEN/TC 350).

OPTIMIZATION-BASED MONITORING-SUPPORTED CALIBRATION OF A THERMAL PERFORMANCE SIMULATION MODEL
Building performance simulation is being increasingly deployed beyond the building design phase to support efficient building operation. Specifically, the predictive feature of the simulation-assisted building systems control strategy provides distinct advantages in view of building systems with high latency and inertia. Such advantages can be exploited only if model predictions can be relied u...

The incitements from society for life-cycle assessment (LCA) and credible ecolables are ever-increasing and often important for successful marketing of products. Robust assessment methods are important for comparable, useful and trustworthy LCAs and ecolables. In order to improve the metrics of a product’s ecolable, is it important to fully understand its production system. Discrete Event Simul...
متن کاملAssessing Embodied Energy and Greenhouse Gas Emissions in Infrastructure Projects
Greenhouse gas (GHG) emissions from construction processes are a serious concern globally. Of the several approaches taken to assess emissions, Life Cycle Assessment (LCA) based methods do not just take into account the construction phase, but consider all phases of the life cycle of the construction. However, many current LCA approaches make general assumptions regarding location and effects, ...
