There are many small firms offering installation of heating, ventilation
or air conditioning systems. In order to calculate the correct system to install the
engineers have to perform a series of elaborate calculations which involve everything from
which way a room faces to the humidity of the air outside. It must be very tempting to do
a "guestimate" after a while, especially if the engineer has years of
experience.
A far better option is J-Works. The user interface is really excellent, the engineer does
not need any computer knowledge at all, the controls are so well designed. The first
screen has a location finder - once you select the town nearest to the one your building
is in, a mass of information about winter and summer temperatures and pressures is
provided, and the next screen slides in. This one is really neat - fill in the square
feet, what kind of walls and floors, even little details like blinds or curtains, and with
virtually no typing and very little effort, all the pertinent details of the building are
recorded.
It is possible to do a room-by room load to make absolutely sure the calculations are
accurate, with a set of blueprints and the built-in calculator the engineer will create a
load report of intense detail, which can be saved, printed out and modified as required.
The resulting installation will be more efficient, more comfortable and last a lot longer.
J Works is a well designed product obviously created by somebody who knows and understands
the trade, and appreciates what really matters in system design. No good Air Conditioning
engineer should be without it. It is only suitable for American systems at present as
there is no British information in the database.
