The Elite Software CHVAC program quickly and accurately calculates the
maximum heating and cooling loads for commercial buildings. CHVAC allows
an unlimited number of zones which can be grouped into as many as 100 air
handling systems. CHVAC automatically looks up all cooling load and
correction factors necessary for computing loads. In addition, the
programs can look up outdoor design weather data for over 1500 cities
located around the world. There is also provision for editing the weather
data as well as adding data for other cities. Comprehensive reports list
the general project data, detailed zone loads, air handler summary loads,
outside air loads, total building loads, building envelope analysis,
tonnage requirements, CFM air quantities, chilled water flow rates (if
applicable), and complete psychrometric data with entering and leaving
coil conditions. Other outstanding features include ASHRAE Standard 62
analysis, automatic building rotation, 360 degree wall orientations,
tilted glass, exterior shading, internal operating load profiles, variable
indoor design temperatures, people diversity, pretreated outside air,
seasonal infiltration and ventilation rates, reheat loads, duct gains and
losses, and return air plenums. CHVAC project data files can also be used
by Florida's EnergyGuage FlaCom 2001 and Elite Software's EZDOE energy
analysis program. |

There are five versions of the CHVAC program; 2 zone capacity ($295), 10
zone capacity ($395), 50 zone capacity ($595), 100 zone capacity ($995),
and unlimited capacity ($1495). Keep in mind that a zone is a single space
or room, and that zones can be grouped into air handling systems which in
turn make up the building. Zones can optionally be grouped under vav boxes
as well. This allows CHVAC to compute diversified peak loads at four
levels in one run of the program: zone, vav box, air system, and total
building. The maximum number of air handling systems allowed for any
version is the number of zones allowed or 100, whichever is the lesser.
Each CHVAC version is exactly the same with the exception of the zone
capacity and price. However, there is a generous upgrade policy. If at any
time you decide to obtain a version of CHVAC with greater capacity than
the original one you obtained, all that is required is to pay the
difference in price between the two versions. |
