Implementation and application of a new bi-directional solar modelling method for complex facades within the ESP-r building simulation program

Submitted by on Mon, 06/23/2014 - 11:22

This paper provides an overview of a new method for modelling the total solar energy transmittance. It is implemented in the ESP-r building simulation program to model complex façades such as double glazed façades with external, internal or integrated shading devices. This new model has been validated and tested for several cases.

Fixed shading systems are saving energy by reducing the cooling loads of the space they shade, but can be a source of energy losses due to the increased need of daylight that they create. Aim of this paper is the comparative assessment of different typologies of buildings' shading systems with integrated photovoltaics. The assessment is focused on their energy efficiency and degree of internal visual comfort conditions that they can ensure. The purpose of the comparison is to optimize the combination of shading systems and their integrated solar cells.
