Introduction

Permasteelisa is a worldwide operating façade contractor.

Physibel (Belgium) develops thermal software for building applications.

The Physibel software is used worldwide by Permasteelisa.

1) for standard U-value calculations of façades

2D steady simulation

2) for advanced thermal simulations

3D / steady state and transient / advanced infrared and solar radiation /

fire simulations /ventilated façades

Physibel program BISCO

5

2D steady state heat transfer simulation

Program principles: example wooden_frame_sample_Bisco.bsc

comparison Bisco vs. Therm: Bisco_vs_Therm_isotherms.png

BISCO uses a 256 colour BMP drawing.

The module BiscoDxf converts DXF to BMP: example Frame1.dxf

The BMP file is imported into BISCO: Frame1a.bsc

and automatically processed according to standard rules: Frame1b.bsc

BISCO allows replacing the insulation panel by a glazing: Frame1c.bsc

The equivalent thermal conductivity of cavities is basically calculated

according to EN ISO 10077-2, but a converter is available to apply the ISO

15099 rules.

An advanced radiation model (view factor based radiosity method) is

available: Frame1d.bsc.

Physibel program CAPSOL

12

Building 1D transient heat transfer simulation

(equivalent to Trnsys, EnergyPlus, …)

The target of transient building simulation is

- to predict the thermal comfort (for example transgression houres)

- to predict energy demand for heating and cooling

over a whole year period

taking into account real climate data
