The complex provides the community with a two-level underground parking garage as well as an area for performing arts and a research li brary. Ferry & Henderson, Architects. 52 Co-op City: Learning to Like !t Robert Venturi, one of this country's most original and controversial architects, and Denise Scott Brown discuss the aims, achievements, and significance of Co-op City, a low-cost project that will house over 60,000 people. The authors suggest that if carefully considered, Co-op City should shake up some newer planning and urban design theories. Herman J. Jes' sor, Architect. 64 Four Proposals: Rapid Economical Production of Mass Housing Two Connecticut architects have developed an un- usual series of solutions related to research in housing and urban development, that will also meet the chal lenge of HUD's "Operation Breakthrough." Solutions that will permit the use of different structural tech niques with such basic materials as concrete, steel, plastics, as well as a combination of these, are illus trated.

Rosen is Chief Specifications Writer of Skidmore, Owings & Merrill, New York. The hazards of air and water pollu tion are slowly being recognized as more statistical information on their effect on the human environment is coming to the attention of a con cerned citizenry. Since the pub lication of Silent Spring, by Rachel Carson, people have begun to ques tion the dangerous side effects that result from chemical pesticides, au tomobile fumes, and raw sewage dumped into our streams and rivers. Industrial and human wastes, care lessly or innocently disposed of into the atmosphere or into rivers, have an effect on nature's biological bal ance that governs the production of oxygen and the growth of marine and animal life. In addition, as archi tects, we should decry the despolia tion of our environment resulting from the accumulation of physical mounds of garbage, junked cars, and industrial waste products. We should also take a closer look at our construction practices to deter mine whether we are a party to this pollution as a by-product of our de signs, and whether we can reduce or eliminate some of our own contribu tions to this problem area. Certainly in demolition of existing structures in urban centers, we should restrict the amount of dust that develops. In some European cities, barriers consisting of plastic envelopes are utilized around demol ition sites to confine the dust result ing from these operations. Perhaps our Building Departments and our Air Pollution Control Departments should institute stricter controls over such procedures. A more striking example of how architects can reduce pollution that actually contributes to fatalities is in the selection of certain sprayed-on fire proofing and insulating products. In 1900, a London physician, in performing an autopsy upon the 102 Specifications Clinic i body of an asbestos-textile worker found asbestos particles in the lungs and attributed this death to the worker's occupation. Several iso lated instances occurred subsequently where an examination of the lung tissue of deceased asbestos workers indicated the presence of asbestos. In 1924 an English physician, Dr. Cooke, after an extensive autopsy and subsequent search of medical lit erature, concluded that the death of a patient resulted solely from the in halation of asbestos fibers and as signed the name asbestosis to this disease. An investigation of some 363 as bestos-textile workers in Great Brit ain in 1928 disclosed that 95, or about 25 per cent, showed evidence of asbestosis. As a result, legislation was enacted in Great Britain to re quire improvements in ventilation and exhaust systems in asbestos-tex tile plants and periodic examination of workers. Although this improve ment in working conditions length ened the life expectancy of these workers, it was learned in 1935 by Dr. Lynch in this country that as bestos workers were dying of cancer as a result of their association with asbestos. Independent investigators in many parts of the world were like wise coming to the same conclusion based on their studies of the associ ation of workers with asbestos. Dr. Selikoff, of New York's Mount Sinai Hospital, had an opoprtunity to examine the records of members of the Asbestos Workers Union. The study covered a total of 1522 in sulation workers between 1942 and 1962. It was found that the death rate from cancer among these as bestos workers was about seven times greater than that of the gen eral white male U. S. population. These observations are staggering. In addition, one must conclude that not only are people who actually work with asbestos exposing themselves to asbestosis and cancer, but also that allied tradesmen in the building con struction industry, closely associated with this work, are subjected to this exposure. Steam fitters, electricians, carpenters, acoustical workers, ma sons, structural steel erectors, and others employed on projects using spray-asbestos insulation in the area of this contamination, and who in hale these asbestos particles, are ex posing themselves and are likely can didates for this disease. Equally disturbing is the fact that asbestos is practically indestructible; while it may disintegrate, it is an ev erlasting contaminant in the atmo sphere. It has been estimated that during its application as fireproofing to structural steel members and metal decks, about 10 per cent overshoots and is projected into the atmosphere. On high-rise structures in urban areas, spray-asbestos fireproofing has been found three and four blocks from the construction site, so that the unsuspecting general public is likewise subjected to this hazard as well as the tradesman directly in volved in its application. While this relationship between a casual en counter with asbestos and possible development of disease in the public has not been established,'it behooves the architectural profession to con sider other materials to perform the work of sprayed-on fireproofing and insulation. Not only is there a clear and pres ent danger in the initial application of asbestos on the health of the in stallers, but 30 or 40 years hence, when these buildings are torn down, the demolition operations, if not properly controlled, will add more as bestos fibers to the atmosphere. The time to use substitutes for asbestossprayed insulation is now. FEBRUARY 1970 P/A If you look at PPG Performance Glass, you can see its beauty. Look into it, and you'll how to get a better building. m (For the sam e money you'd spend on conventional glass.) , PPG Performance Glass enabled the architect for the new Cities Service Building in Atlanta to achieve the exact esthetic effect he desired. He chose to use the reflectivity of the Solarban* Twindow* Unit as an active design medium. The facade is never static . . . its color and tone change as constantly as |he cloud patterns and sky tones iange. In choosing Solarban Twindow inits, the architect and mechanical tgineer also found that the arformance characteristics of the | ass would offset its higher cost ' contributing to savings in HVAC guipment and capacity costs. The result: "W e were able to iild a superior building at the |me cost as with conventional aterials." {.Significant mechanical system zings can be realized with Solarin Twindow Units because of the reflective coating which turns back much of the solar radiant energy, rather than permitting it to become a load on the cooling system. This same low-emissivity reflective film on the Solarban Twindow Units (normal insulating glass constructions with a V2 " air space) enables them to perform like triple glazing in reducing conducted heat loss during the winter. In addition, chilly downdrafts and condensation are significantly reduced. Put PPG Performance Glass to work in your next building. It can help realize significant savings in mechanical systems costs, reduce brightness, aid in temperature control or reflect to enhance the exterior design.

And the average number of days with sun in Denver is about 300. We still expect the glass to pay for itself in 3 to 5 years in the savings from mechan ical system operating costs." Mechanical system requirements and costs can be reduced when Solarban Twindow Units are used because of the reflective coating which turns back much of the solar radiant energy, rather than permitting it to become a load on the cooling system. This same low-emissivity reflective film on the Solarban Twindow Units (normal insulating glass constructions with a W air space) enables them to perform like triple glazing in reducing conducted heat loss during cold weather.
