BSIMAC 9 – Building Energy Analysis Software
Cooling Loads, Heating Loads, Annual Energy
Certified Thermal Calculation Software
Overview of Bsimac 9
Bsimac 9 is an advanced HVAC Design tool and Building Energy Analysis software. It is aimed at assisting engineers and architects in the design of thermally efficient buildings.
* 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
The main functions of Bsimac 9 are outlined below.
Bsimac 9 offers two-in-one functionality – you can carry out HVAC Design, 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 modeling effort for two separate models.
The HVAC Design function is for determining the cooling and heating loads and the required capacities and performance of air-conditioning equipment. You have access to many design options, comprehensive weather and locality data, and building materials and construction data banks.
The Annual Energy Simulation function is for determining annual energy consumption and electrical demand and for demonstrating compliance with SANS 10400-XA through Rational Design for all classes of buildings and all types of construction (including light or heavy construction), as certified by Agrément South Africa.
Air-conditioned buildings:
The determination of cooling and heating loads and the required capacities and performance of air-conditioning equipment.
The effects considered include the effects of the building itself and of the HVAC design parameters.
Some of the effects that can be evaluated with Bsimac 9 are shown Here.
The determination of annual energy consumption and electrical demand for the whole building.
(a) Simulation for the building only – valid for Architects during the initial development stage. Read More
(b) Simulation for the building with HVAC equipment, hot water system, and vertical transport. Read More
Demonstration of compliance with SANS 10400-XA (or other regulatory authorities) through rational design
You get your simulation results in minutes, no need to wait hours to evaluate each ‘what-if’ option Read More
Naturally Ventilated Buildings
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.
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
These options help 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 EPW, TMY, TMY2, and others. Links are provided to EPW format data for over 500 South African locations and for thousands of world locations
