American Society of Heating and Ventilating Engineers

Program for Annual Meeting

OLLOWING are the principal fea-

tures of the program for the annual
meeting of the American Society

of Heating and Ventilating Engineers,

January 27-29. To comply with the so-
ciety's constitution, an opening session
will be held in New York, January 26,
but no business of importance is sche-
duled for that session. The members
will then adjourn to Buffalo, N. Y.,
where headquarters will be established
at the new Hotel Statler. There the
meeting proper will open Wednesday
morning, January 27.

Entire sessions are to be devoted, one

to the proposed amendments to the so-

ciety's constitution and by-laws and the

other to the attack on mechanical venti-

lation launched by the American Public

Health Association (the full text of the

resolution adopted by the American Pub-

lic Health Association was published

exclusively in THE HEATING AND VENTI-

LATING MAGAZINE for December, 1925).

sprayed into the rink and freezes as it

falls, and by the construction of the

tank floor to permit a rapid heat trans-

mission.

William H. Driscoll, chairman of the

society's Committee on Research and

nominee for president next year, gave

an interesting review of the situation

in the society, due to the desire of the

western members for fuller representa-

tion in its affairs. He thought this be-

tokened a healthy condition, as con-

trasted with that existing when the of-

fice has to seek the man. He predicted

a lively session on this subject. at the

forthcoming annual meeting in Buffalo,

January 27-29, and offered it as one of

the compelling reasons why all who

were able to do so should attend the

Buffalo meeting.

Another attraction at the annual meet-

ing, said Mr. Driscoll, will be the pres-

ence of Dr. C. E. A. Winslow, president

of the American Public Health Associa-

tion, whose resolution condemning mech-

anical ventilation has set the industry

by the ears.

A whole session of the annual meet-

ing will be given over to Dr. Winslow's
address and of those representing the
mechanical ventilation side of the con-
troversy.

It was announced that the January

meeting of the New York Chapter will

be a joint affair with local members of

the American Society of Mechanical En-

gineers. The usual dinner will be

served at the Building Trades Club,

after which the meeting will adjourn to
the Engineering Societies Building, 29
West 39th Street, where the subject for

Heating and Ventilation of Buildings. New York Chapter Discusses discussion will be "Domestic Heating."

Illinois Chapter Hears Talk

on Chicago's Union

Station

Mechanical features of the new Union
Station in Chicago were described by
E. Brock, mechanical engineer in charge,
at the December meeting of the Illinois
Chapter. An idea of the size of this
building was given in the statement that
the waiting room is 400 ft. by 700 ft.
The power load of the building is be-
tween 3000 and 4000 H.P.

Eight new members were elected, as

follows: Harold Cornell, Davies Supply

PROBABLE BUILDING TOTAL FOR 1926

The accompanying table indicates the
anticipated expenditures for new build-
ings during the year 1926, classified ac-
cording to nineteen types of structures
and divided into six geographical divi-
sions of the United States. This tabula-

tion shows the amazing total of $5,584,-
782,500, which will pass over the boards

of architects and into actual construc-
tion during the year 1926. In addition
to this vast sum to be spent for building
materials and labor, there must be con-
sidered the fact that in the small house
field and that of industrial construction
there is considerable building not de-
veloped from architects' plans, probably
totaling another half billion dollars.

New Officers of the

Pittsburgh Chapter

New officers of the Pittsburgh chapter,
elected at the November meeting are:
President, C. W. Wheeler; vice-presi-
dent, H. Lee Moore; secretary, Margaret
Ingels; treasurer, Frank J. Firsching.
Board of governors: J. E. McGinness, P.
A. Edwards and F. C. Houghten.

A letter from the Kansas City Chapter,

containing the resolutions adopted by

that chapter, was read. After some dis-

cussion it was voted to refer the matter

to the chapter's board of governors.

Thus it is predicted that 1926 will be another six billion dollar building year, with certain changes in the relative proportions of activity in building types and districts.

There will be approximately the same relative building activity in each of the six geographical divisions of the United States during 1926 as compared with 1925 with some decrease in the Northeastern and Middle States and a considerable increase in the Southeastern States (due to activity in Florida).

The probable "normal" building year of today is four billion dollars or more and on this basis it would take three or four six billion dollar years to meet the still-existing shortage!

All is well with the building industry. It is going about its business seriously, contributing to the wealth and comfort of the nation. Some idea of the magni tude and importance of the construction industry may be gained from a statement recently made by Secretary of Labor Davis in which he said: "More than 11,000,000 of our people are dependent for their living upon the construction industry, and 22% of all the skilled and unskilled labor of the country is engaged in the building branch alone. Some 250,000 freight cars are required to handle the materials. Our building bill is $200 per year for each family in the United States. It is truly the chief barometer of the business of the country.

New York's Fourth Power Show

VER 400 exhibitors, of whom 73 were manufacturers of apparatus and appliances used in heating and ventilating work, was the record made at the Fourth National Exposition of Power and Mechanical Engineers, now known as the Power Show, held at the Grand Central Palace, New York, November 30 to December 5. This number represents an increase of 130 over last year's total of exhibitors. The attendance increased at an even higher rate, jumping from 47,000 in 1924, to 100,000 last year.

Among the lectures given, during the Power Show, in the Conference Room of the exposition hall, was one on "Recent Developments in Heating and Ventilating," by President Samuel E. Dibble, of the American Society of Heating and Ventilating Engineers.

Recent Developments in Heating and

Ventilation

Professor Dibble divided his address into two sections, the first dealing with heating and ventilation as a mechanical device for efficiency and economy of operation, and the second, with heating and ventilation as a mechanical device for the promotion of health.

STATUS OF BOILER RATING

On the subject of heating boilers and the progress made in their commercial rating by the American Society of Heating and Ventilating Engineers and the Heating and Piping Contractors' National Association, Professor Dibble said:

"Heating boilers of the cast-iron lowpressure type have been greatly improved, and I believe will be still further improved within the next five years. With the development of the A.S.H. & V.E. Heating and Ventilating Code, and the adoption by the boiler manufacturers of their Low-Pressure Boiler Testing Code, all cast-iron boilers are now tested for over-all efficiency. There has been some valuable work done by the Heating and Piping Contractors' National Association in its attempt to give a commercial rating to all low-pressure cast-iron boilers after they have been tested in accordance with the A.S.H. & V.E. Boiler Testing Code.

EDUCATION OF PUBLIC NEGLECTED ON

ENGINEERING SUBJECTS

"In the heating and ventilating industry, however, we have sadly neglected one very important point, and this is typical of the entire engineering group of industries. We have highly developed our industry, and among ourselves we are thoroughly convinced and we know whereof we speak when we state that a building can be heated and ventilated according to a predetermined condition. Where we have fallen down is in the education of those who are to occupy the buildings and others. We put in a heating and ventilating system, and then we issue orders that no windows in the building shall be opened. To my mind, this is a challenge for everyone to ignore the order and open the windows at the first opportunity. We issue orders upon the completion of our heating and ventilating job that no valves and no part of the mechanism must in any way be touched. This again is a challenge for the people who receive the orders to operate the valves and the levers upon the first opportunity presented. In my mind, it would be much better if we, as an industry, instead of giving orders what not to do, would give out information stating exactly what to do and how the heating and ventilating system functions, and what it will do when it functions properly.

[blocks in formation]

"The time is not far distant when city homes at least will be fitted with equipment furnishing properly-filtered, properly-humidified, and properly-heated air. During the past year it has been brought to my attention very forcibly by a system which I designed for a private home, in which all the air that entered the home was cleaned by means of dry air cleaners, was humidified properly by means of a humidifying device, was heated by means of indirect radiation, and air was distributed into the rooms by means of a fan and exhausted from the rooms by means of a series of ducts.

"The operation of such an equipment is not very expensive and it is not beyond our vision to expect that this industry will provide means for cleaning all the air which is discharged into buildings for ventilating purposes.

"In fact, if we let our imagination play for a minute, we might even suggest that all the air that we breathe will in a short time be cleaned and

"These two organizations are bending every effort to assist one another in this enterprise, and it is hoped that before long every boiler manufactured in the United States will be tested in accordance with the recognized code, and will be rated in accordance with the recognized method of rating, thus giving uni- freed from all outside contamination. form results and information to the contractor and owner which will enable them to successfully select a low-pressure boiler for a given job."

What seemed impossible years ago in the cleaning, the filtering, and the purification of all the water consumed in large cities, is to-day accepted as a com

mon and simple undertaking, so much so that we will even water our streets and water our lawns and gardens with water which has been treated and made pure. Why is it not just as possible to conceive of having all the air we breathe cleaned in a similar way, and thus eliminate sickness and death caused by improper and unhealthy air?"
