WHAT IS BLOCK LOAD ?

Block Load is a powerful, fully featured HVAC load estimating program suitable for commercial building of any size.

WHAT DOES IT DO ?

Block Load takes the building data you supply, and returns information that you need to complete your HVAC work. From quick "block" loads to detailed zone load information. A detailed breakdown of the zone loads (wall, roof, glass loads, etc.) and system loads (ventilation, plenum loads, fan heat gain, etc.) are available for analyzing various system designs. You can also get coil selection information like total and sensible tonnages, supply air flow rates, and coil inlet and outlet temperatures. Or let it help you select a fan or diffusers, with zone and system air flow rates. And, of course, you get lots of handy "rule-of-thumb" check figures, like the system square foot per ton, cfm per square foot, and overall building U-value.

HOW DOES IT WORK ?

The Block Load program features a unique 4-step approach to load estimating. The program guides you through each step from start to finish. In STEP ONE, you select the city weather data to be used in the load calculations. With Block Load's weather library of over 500 cities, you'll probably find the city you want. But if you don't, it's a simple matter to enter a few weather parameters, and new weather data will be generated for you.

In STEP TWO, you enter the data for each zone in your system. The zone data file holds up to 150 zones, so you won't be cramped for space. And data entry is easy with such features as full-screen editing, streamlined input screens, and an on-line calculator.

In STEP THREE, you describe the HVAC system. Does it provide both heating and cooling ? Warm air, hydronic or electric baseboard heating ? How much ventilation air is being brought in ? Is it a single-zone rooftop unit, or a large, multiple-zone central air handling unit ? For your convenience, you can store forty separate systems in the HVAC system file.

In STEP FOUR, choose the calculation times and printouts you want to see. The program does the rest.

FOUR REASONS TO CHOOSE BLOCK LOAD

1) EASE-OF-USE: Even computer novices will find its unique 4-STEP approach simple. What's more, complete on-line help is available at the touch of a key. And data entry is easy with such features as full-screen editing, streamlined input screens, and our on-line calculator.

2) ACCURACY: Cooling load calculations feature the ASHRAE-endorsed Transfer Function Method instead of simply computerizing a table-based hand calculation method. This gives you mainframe accuracy without the mainframe difficulty.

3) VERSATILITY: Block Load is ideal for preliminary sizing calculations or for final design submittals. And where else can you run a simple rooftop job and a 150-zone central air handler job with equal ease ? In English units or S.I. Metric units. With presentation quality printouts.

4) SUPPORT: We offer free, unlimited telephone support from a staff of trained specialists. And with any of our E20-II software, you get a subscription to our NEWS-II newsletter, which will keep you informed of important trends in software development, and provide valuable tips and assistance.
