Overview of Bsimac 9

Bsimac 9 is a comprehensive building energy analysis software aimed at assisting engineers and architects in the design of thermally efficient buildings. 

The main functions of Bsimac 9 are outlined below.

For air-conditioned buildings:

Design of HVAC systems – The determination of cooling and heating loads and the required capacities and performance of air-conditioning equipment.   
[Read more]

Annual energy simulation – to determine energy consumption and electrical demand.

Demonstration of compliance with SANS 10400-XA through rational design 

(a) Simulation for the building only – useful for Architects during the initial development stage  
     [Read more]

(b) Simulation for the building and HVAC equipment with simplified HVAC equipment simulation  
     [Read more] 

(c) Simulation for the building and HVAC equipment with full HVAC equipment simulation.

Fast simulation  –  You get your simulation results in minutes, no need to wait hours to evaluate each ‘what-if’ option  [Read more]

Bsimac 9 offers two-in-one functionality - you can carry out HVAC Design calculations and in addition carry out the Annual Energy Simulation in terms of SANS 10400-XA, using virtually the same data input . There is no need to have two separate software packages and duplicate your modelling effort for two separate models.

For naturally ventilated buildings:

Passive design – thermal analysis of the building, including the effects of the building envelope, shading, infiltration rates, and building orientation on indoor temperatures, inside surface temperatures of walls, windows, roofs and glazing, cooling and heating loads, and annual energy requirements. The effects of natural ventilation, e.g. with increased night ventilation, can also be determined.

Indoor temperatures – The determination of indoor temperatures with no mechanical cooling or heating for:

(a) a hot Summer day  

(b) a cold, cloudy Winter day 

(c) a cold, sunny Winter day  

This option helps to investigate the effects of various passive design options on hourly indoor temperatures of different areas in the building.

Climatic data included with Bsimac 9: 

  • Design climatic data for all major centres and many other South African locations for 12 months of the year
  • Climatic data for energy simulation for 25 localities in South Africa for 8760 hours of the year
  • Additional design climatic data for many South African and over 5000 world locations can be generated from within Bsimac 9
  • Additional weather data for energy simulation can be imported to Bsimac 9 from international weather data in formats, such as  TMY, TMY2, EPW

Materials data included with Bsimac 9:

  • Building and insulating materials – the user can edit this data or enter new data
  • User-defined wall / roof / floor constructions

Bsimac 9 will work with jobs (projects) of any size –  No  limit  to  the  number  of  rooms  (zones)  or  plants

Worldwide functionality -  Bsimac 9 will work anywhere in the world, but includes many weather and material files specifically for South Africa.
