HASShouse, incorporated into HASS as a utility, is a stand-alone fire protection software program for hydraulic analysis, design and review of residential sprinkler systems in accordance with NFPA 13, 13D, and 13R.
Featured in a 1987 Operation Life Safety Workshop at the International Association of Fire Chiefs in St. Louis, HASShouse was highlighted as a specialized tool to reduce the volume of paperwork and speed up the design and review process with its quick and accurate analysis procedures. As the residential sprinkler market grows, HASShouse is the specialized tool for every residential sprinkler design or review situation. HASShouse is updated annually to comply with standards’ revisions and new sprinkler and piping specifications.
Data Entry
Data Entry is quick and tailored to the residential sprinkler market. Data can be entered and revised without delay. The system layout is described by nodes (K-factors and elevations) and by pipes (lengths, diameters, and fittings). Special tables allow for quick selection of pipe (Pipe Tables) and types of residential sprinklers (Sprinkler Lists). Pipe tables and sprinkler lists can be edited as needed. Pumps, meters, and backflow preventers are entered by changes in pressure.

Calculation Processes
Calculations use the same engine as HASS. HASShouse gives results for an adequate flow in the design area with the hydraulically most remote one sprinkler operating as well as two-to-four sprinklers operating. HASShouse automatically provides these two required sets of calculations.
Results
Results appear in a clear and concise report with the option of using the older HASS format or the 2007 NFPA report format with an automatically generated cover sheet and water supply graph, ready for your review on the screen before printing. The two sets of calculations are shown in a single report.
Special Features
DRISCAL
DRISCAL is a special routine for developing a drain test assembly for metering the flow rate to simulate the required sprinkler and domestic demand and pressure.
NETWORK
The NETWORK calculation routine includes an automatic network generator for systems using ½ inch
cross-linked polyethylene piping as specified in paragraphs 3.3.9.4, 6.3 and 8.4.3.3 of NFPA 13-D. HASShouse NETWORK calculates all single sprinkler flow rates, and the two most remote sprinklers in the report.

Questions and Answers
● Q. How will I enter data for HASShouse to calculate?
A. You can enter data directly on the screen as well as call up stored data for approved sprinklers, piping, tubing and fittings (to make several entries with one keystroke). Also, equivalent K-Factors compensate for armovers and drops. These features both speed up data entry and assure greater accuracy.
● Q. Will I need to use NFPA 13D to look up fitting equivalent lengths?
A. No. The program looks up this data for you using built-in tables. You can enter the number of fittings for a run of pipe as well as the nominal diameter of the pipe, as well as add new tables when you need them.
● Q. How will I include a pump, meter, or backflow preventer?
A. By showing the pressure change for the device along with other data for the run of pipe.
● Q. What are the advantages of using HASShouse for residential calculations?
A. There are two major advantages: First, HASShouse is tailored to the residential market with quick and easy data entry from pipe tables and sprinkler lists that complete several fields at once. Second, review and approval are easier with HASShouse because the report is clear and concise, showing the results for one sprinkler operating along with the results for 2 to 4 sprinklers operating, with both results summarized on a coversheet and plotted on one N1.85 graph.
● Q. Where can I see the results of a typical HASShouse calculation?
A. The residential sprinkler system layout on the next page is followed by a complete report that includes a coversheet, the calculations, and an N1.85 flow curve ready for submittal and review.
HASShouse Coversheet
Coversheet information accompanies the report and includes specifications for piping and sprinklers, sprinkler spacing, water supply, sprinkler demand and the name of the reviewing authority. This information is provided directly during data entry, or is read from pipe tables and sprinkler lists as accessed by directory during data entry. Calculated K-factors are given for the selected sprinkler when fed by armovers or drops, and fed through the specified type of piping. The minimum end-head flow calculation while the FULL FLOW ONLY calculation gives the total volume for 7 and 10 minutes.
Results of Analysis
Results of Analysis are presented on one page with pipe and node data to the left, the analysis is for one sprinkler shown in the center, and the analysis for all specified sprinklers shown to the right. These groups of results are separated in the heading by asterisks (*). Pipe data is provided in two rows with related items in columns.
Water Supply Curve
Water Supply Curve results are presented for two sets of calculations, one set for one sprinkler flowing and the other set for all specified sprinklers flowing. The X axis (N1.85) represents water flow, while the Y axis represents water pressure. (The curve appears to be flat because a typical test flow is much greater than the residential sprinkler system demand).
The legend includes the water flow test data used by the calculation. Points A and C indicate the water supply available for the first and second sets of calculations, while points B and D indicate the corresponding water demand.
