Simplifying engineering designs for modern building professionals
Accurate building calculations you can count on each time

Modern buildings are constantly evolving making it harder to design building services. With so many nuances and components, analysing the big picture is really complex. With HYENA+ you can you can calculate, design, size and refine fire protection systems easily with total peace of mind.

HYENA+ simplifies your hydraulic calculation needs and is the fire services industry’s trusted gold standard for calculating automatic fire sprinkler, fire hydrant, fire hose reel and water mist systems.

Accessible anywhere, ACADS-BSG’s latest software solution HYENA+ is now in the Cloud. HYENA+ can be used to analyse automatic fire sprinkler systems with a simple end, side or centre fed configuration or more complicated looped and gridded systems. It may also be used to analyse fire hydrant and hose reel installations, or combined sprinkler, hydrant and/or hose reel systems, or any other hydraulic systems where the discharges can be represented by a k factor and minimum flow.

With a given sized network the program performs a complete hydraulic analysis determining flow, pressure drop, and other technical data for each pipe in the entered network, taking account of all fittings entered by the user.

The Main Screen of HYENA+

Main features of HYENA+ are:

  • Accessible anywhere, ACADS-BSG’s latest software solution HYENA+ is now in the Cloud. If you have access to the internet, you have access to HYENA+ , wherever you are.
  • Capable of analysing looped, gridded and tree systems.
  • HYENA+ can be used to carry out a fire sprinkler system analysis in accordance with NFPA, NZ4541, AS2118 or SSPC52.
  • Capable of analysing fire hydrant systems, with or without hoses or hose reels.
  • The network piping system can have up to 10 input points, and these can be modelled as a fixed pressure, town mains water supply, or via a pump.
  • Works with a wide range of units including Metric, British lmperial, or US lmperial.
  • Use either the Hazen-Williams or Darcy-Weisbach calculation methods.
  • All input data is via a series of easy to navigate screens with numerous helpful features including drop down lists, selection lists, various sort options, etc. to facilitate easy data input.
  • All nodes that are not nominated as discharges, or input points are automatically assigned as reference nodes where you only have to assign elevations, saving significant data input time.
  • Piping materials complying with a wide range of codes are catered for including light, medium and heavy steel piping, cast ductile iron pipe, and copper tubing to Australian standards, New Zealand standards, API piping codes, all selected from a drop down list.
  • When pipe sizes are entered as nominal sizes, the program determines the actual internal diameter from data stored in the program for the different pipe materials. The user can add to this list by entering their own custom pipe materials and associated internal diameters.
  • Sort pipes by ascending or descending order, edit particular pipes and nodes, and globally change the pipe diameters or lengths with ease via the use of the global change function.

The Pipes Data Entry Screen

  • A wide range of fittings are provided for with equivalent lengths stored in the program. Users can add to this with their own fittings and associated equivalent lengths, or to modify specific fittings via uploading alternative equivalent lengths.
  • Booster pumps can be located anywhere in the network. Back flow preventers can also be included, and check valves can be made to restrict flow to one direction in any given pipe.

The Fitting Selection Screen

Setting the Elevation for a Gridded System with Rising Main Pipes.

  • Three Calculation Options: Calculate the required Input Point Flow and Pressure | Calculate the discharge flow for the given input | Calculate the Booster Flow and Pressure
  • The program can be used to determine the design point (required flow and pressure at the input point) given the k factor and minimum discharge of each fire sprinkler head, fire hydrant or fire hose reel. Alternatively, a pump or water supply characteristic, or a fixed pressure can be entered for one or a number of input points, and the program then determines the flow from discharging heads, nozzles or outlets, and the operating point on the entered water supply or pump flow characteristic curve(s).
  • Provision is made for gridded layouts to be entered easily. This grid can contain one, two or three main pipes with range pipes between and branches to the left or right as required. Any number and arrangement of sprinklers on the grid can be made operational and the program can find the least hydraulically favourable position of these operating heads across the grid if requested. Nodes and pipes are automatically numbered when the grid facility is deployed.
  • A graphical display of the grid is provided. The user can elect to display pipe numbers, node numbers, pipe diameters or lengths.
  • In a grid scenario, sprinkler elevations can be fixed at a given height, entered individually across a grid row, or entered as a single slope or pitched slope across the grid row. These parameters can be used in combination and row elevations are automatically duplicated in subsequent rows up the grid until the next row elevation specification.
  • The grid commands can be converted into the longhand detailed individual pipe and fire sprinkler listing/code, thereby enabling modifications to be made to the basic grid via the XPan function.
  • The calculations undertaken by HYENA+ utilize complex mathematical formulae and methods for each loop in the system, and these calculations are not only very fast, but also incredibly reliable, allowing very large systems to be analysed.
  • The results include a Summary of the flows and pressures for all discharges and all input points. This is followed by a detailed table of Pipe information including the total equivalent length, pressure drop, etc., for every pipe in the system, coupled with a detailed table of Node information. This includes the pressure at each node and the also flow if the node is a discharge or input point. The total volume of the piping system in litres is also calculated.
  • HYENA+ can also determine quantities from the entered system including pipe lengths and numbers of fittings categorised by pipe material type and diameter.

The user interface for HYENA+ is much cleaner and more user friendly than the UI used for the original HYENA program. This makes the experience more enjoyable, easy, and less taxing when using the program for long periods of time. HYENA is an excellent tool to have and its now web-based nature with HYENA+ has allowed it to become even more beneficial.

It has always been a pleasure dealing with ACADS-BSG team due to their helpful nature and quick response time to any inquiries and technical issues. Camel\Hyena works out of the box and install time is in seconds, I cannot recommend any other company that provides better customer service other than Catherine and her team.

– Marvin D

Catherine and the team at ACADS provide customer service of the highest standards always offering the best solutions for our business with fast response times. I would highly recommend ACADS-BSG.

The ACADS BSG suite of software has been used by VOS Group for 30 years. We as a company have grown as the software capabilities have changed with usability and technology. The support from head office has always been quick and accurate, with a resolve to overcome any obstacles. We have always found the outputs to be accurate and reliable and a good basis for good engineering design.

Moving to a cloud based platform has improved the overall performance of the software. [being able to log in from any device] has improved my overall productivity as I only need to carry my smart phone or a tablet, and I can do my job remotely. Tools and functions are clearly organised within the new interface reducing any confusion for a new user. Copy+ Paste option saves a lot of time for Engineers like me. It just works like an Excel Sheet, where you can copy items and paste them somewhere else. It saves a lot of time especially if you are working on a single project and you want to do multiple calculations.

[HYENA+] allows me to quickly switch from one calculation to another without losing any data. This has reduced the overall lead time in doing calculations. I am sure [HYENA+] will have a positive impact on the Fire Industry.
