These partments of about 50 sq m have been used consequently throughout the entire building.　　Application of natural materials timed in as a result. By bining the landscape elements with the architecture, the premises bee particularly Dutch.　　39　　Hooker Office Building, Niagara Falls, . USA.　　Cannon Design Inc.. architect　　The key to the design is 4footwide void between an outer wall of greentinted insulating glass and an inner wall of clear single glazing. Meant that builds up in this gap under sunny conditions can be vented at the roof. Louvers within the void are adjustable to keep out direct rays。 they can be closed entirely at night to keep heat in. Daylight, dispersed by the louvers, provides ample illumination of the outer 15feet of the office floor44 percent of their usable area. Energy analysis of the building as designed showed Hooker39。s heating load to be only about 2 percent of that for a conventional building of the same volume, and its cooling loads only about 19percent.　　42　　Shinjuku NS Building, Tokyo, Japan Nikken Sekkei Ltd., architects　　Shinjuku NS Building is the office tower having about a half height paring the other buildings in the site, where can build the same high as the buildings around it. In the upper part of the first floor plaza, at the height of 130 meters, the big glass roof, 4065 meters, is built. In the future, the plaza built in this building will play an important part as the big fortable element in the street in proportion as the new heart of the city of Tokyo bees the final form and multistored buildings are more built around it.　　62　　A system of Selfhelp Construction　　Adopted in Rural Senegal　　by Dr. Brian Brace Taylor　　The Senegal experience is illuminating because the emphasis was upon an inexpensive building system using locally produced material and maximum local labor rather than a dependence upon imported　materials,　machinery　and expertise.　　Prior to constrution of the Agricultural Training Centre in Nianing, which proved to be a largescale application of the system, a prototype structure was erected on an experimental building site in Dakar under the supervision of experts from the local UNESCO (BREDA) office for educational buildings. Several images included here will suffice to illustrate the rudiments of the system, which involved bearing wall construction, with buttressing, sometimes with arched openings, built of sand and cement blocks manufactured onsite. The same blocks were employed as formwork for the arches and then taken away and reused when the wall was pleted. However, the key innovation introduced on the local scene through this prototype was the roofing which consisted of thin, barrel vaults of cement capable of spanning a maximum distance of m. Demonstrations and tests were conducted on site before the vaults were actually constructed in place, using plywood centers and millet stalks as formwork. The prototype was done under the guidance of a largely western, or westerntrained group of architects, directed by Mr ElJack, a Sudanese architect employed by UNESCO.　　The satisfying results of this experiment, from an economic point of view as well as a social one in having retrained masons, became known to the future client of the Agricultural School, CARITAS, which had a rural development station about 100 kilometers from Kakar. The programme defined by CARITAS was for a school to acmodate 54 resident students from rural villages during two years of agricultural training.　　The significance of the experience in Nianing may be summarized by the following. Techniques developed in utilizing the shortspan vault system on a large scale project aided those who initiated it in judging its overall validity. A structural system using materials in pression rather than tension reduced costs by eliminating the need for expensive steel reinforcing and for wood, which is scarce, for formwork. Locally produced rather than imported materials, which includes the cement, were used in the main.　　A very encouraging indication of the system39。s viability was the fact that there was a kind of proliferation of the system, in the form of new missions for buildings. A primary school classroom was built in Nianing village during construction of the Agricultural Training School. A cooperative grain silo was executed in the even more remote village of Ndlaro, at the request of the local residents. And, the Daara Koranic school designed and closely supervised by Raoul Snelder in Malika, a village very near Dakar was opened in April, 1980.　　70　　Institute of Architecture,　　Hongkong University　　by Liu Baozhong　　Hongkong University is the only institution in the port which offers higher education in architecture. The Institute of Architecture of Hongkong University has a circumstance of five years and an extra year for students are admitted each year. The staff are high leveled and capable. The institute is fully provided with building and facilities far,instruction, library and information, administration and experiment. The environment has the characteristics of architectural profession. The entrance examination for the year 198182 have been quoted in the article to show that the Institute takes the selection of students seriously. The Institute has its outstanding guiding principles and systematic teaching plans. In the training of students, both theory and practice under local conditions are emphasized. The Institute is active in attending international architectural petitions and has won prizes twice in the petitions sponsored by UIA.２８
