Item Towards place-sensitive urban interventions:an examination of the significant characteristics of place in selected urban nodes in Colombo(Sri Lanka Institute of Architects. Colombo, 1998) Rajapakse, A.; Dayaratne, R."place"is a concept that has received recent attention among architects,planers and urban designers.It is seen as a useful concept to exmine and to be employed for planned interventions in the built-environment.place is a spatial entity as well as a social-psychological entity.Its characteristics therefore are intertwines with these aspects.What are the significant refinements of these characteristics that will elevate the quality of places and transform them to memorable cherished places?This was a research question that prompted an inquiry into the urban spaces wherby an attempt was made to recognize and emphasize the significant characteristics of place that will enable place-sensitive planned interventions in jthe city.The study based in examined in detail the characteristics of two selected places that mark them special and significant.The study proposes a theoretical consturct of those characteristics that must be enhanced in planned interventions.Item The urban environmental transition:some reflections on the use of vegetation to monitor urban environmental quality(Sri Lanka Institute of Architects. Colombo, 1998) Emmanuel, R.Urban planning and design action in the fae of rapid global urbanization and attendant changes in the urban environment urgently needs holistic indices of environmetal quality.The use of vegetation changes to monitor urban environmental quality appears plromising ,thanks to recent advances in the remote sensing of greenery.The utility of remotely sensed vegetation data to monitor the urban physical environment is well known.recently,Emmanuel(1997)demonstrated that such data could also mirror the social and demographic trends in cities. this paper explores the urban design/planning implications of using vegetation chantge as indicator of urban environmental trends .The case study is based on research wodrk carried out in detroit .USA,where urban decay in recent years has lead to significant greening in the heart of the city .A hypothesis of urban environmental transition is proposed.Item Analysis of urbanization trends in the greater Colombo area from 1956 to 1994 using air photos(Sri Lanka Institute of Architects. Colombo, 1998) Majeed, M.Item Harnessing natural light for energy efficiency in buildings(Sri Lanka Institute of Architects. Colombo, 1998) Ranasinghe, S.; Perera, R.This paper is written within the premise that lighting accounts for a sizeable portion of the total energy requirements of Sri Lanka.It is also noted that efficiency planned usage of daylight for building interours could result in considerable savings in energy and thereby lead to energy efficiency.TRhe intention of this article is to highlight few key design criteria which must be considered by architects in harnessing natural light to make the buildings they create energy efficient.Although these criteria are commonly known,lack of understanding and application are amply demonstrated in contemporary Sri Lankan buildings.Item Towards a conceptual framework for the conservation of urban heritage(Sri Lanka Institute of Architects. Colombo, 1998) Munasinghe, H.Item Editorial(2000) Dayaratne, R.Item Revitalizing small historic townscapes in Southern province, Sri Lanka:identifying core-elements of town's identities based on residents'and visitors'cognition towns(Sri Lanka Institute of Architects.

Colombo, 2000) Kulatilake, P.Item Rational use of glass in tropical urban climatic conditions(Sri Lanka Institute of Architects. Colombo, 2001) Perera, L.S.R.; Wickramasinghe, N.Glass is a common material us4ed in buildings,mainly for plenestration purposes.Although the physical properties and performance data ofthe wide variety of glass can be easily obtained from technical literature,their performances under specific environmental conditions are not commonly known.While the technical literature presents performance data under laboratory conditions,the same under ambient conditions are not available .However,the post application performence of glass largely depends on the external environmental conditions.This paper attemplts to understand the plerformance of popularly used variety of glasses under tropical urban climatic conditions of Sri lanka.It presents the findings of an exlperimnet conducted under ambient conditions,using a scaled model of a typical office building.Item Strategies for equity and sustainability in urban transportation in third world mega-cities(Sri Lanka Institute of Architects. Colombo, 2001) Emmanuel, R.The conventional approach to transportational problems has been buolding more and better highways.However,contrary to popular and academic expectations,more and better transportation technologies have led to and increase in time spent in transportation strategies,particularly for third world urban agglomerates.The solution proposed here is not an equitabel distribution of more transport power,but a reduction in the need for it.it is argued that a ceiling on per capita energy use by means of design strategies for speed reduction is necessary to promote healthier urban transportation.Strategies for urban design alternatives that achieve this end are proposed.Item Aesthetics of urban space through collaborative urban planning:integrating environmental aesthetics with communicative theory of planning(Sri Lanka Institute of Architects. Colombo, 2001) Munasinghe, H.The collaborative urban planning has the potentials to make cities more aesthetically pleasing to the dweller.in this paper,we focus on the strengths of the said theory to bring in the viwws of the user to the designing process of the urban space.our current research interest int he collaborative planning is also based on its abillity to formulate a wider basis for evaluation,development and conservation of the city and its life.we intend to argue that aesthetics,within the current consciousness,is not what is meant by bearty but what makes the mand familiar within his dwelling splace. Aesthetic therories hellp understanding the perception,appreciation or experiencing of the slpace in everyda;y life.By developing useful tools to discuss the values of urban space,the contemporary developments in the environmental aesthetics,especially within phenomenological and pragmatist philosolphy,could make the communicative planning therory more context-oriented.The current conception of planning as a decision making process that has little to do with humanistic perspective ofthe city is to be challenged and provided with alternatives here.This decision-making deals with many pracitical demands,but its conventional attitude has cost the city life.The communicative theory and collaborative planning as a practice,strengthen inhabitant's relations to the urban space and as such,could create a new as well as manage the existing without losings its links with the users,once reinforced with phenomenological and pragmatist ideaas developed in the environmental aesthetic theories,this new practice could strengthen the urban space to lpromote dwellingItem Creating a quality culture - a need in the new millennium(Sri Lanka Institute of Architects. Colombo, 2001) De Silva, V.Item Teaching architecture as an intervention in thinking:the Moratuwa experiment revisited(Sri Lanka Institute of Architects. Colombo, 2001) Dayaratne, R.Apart from architecture itself,architecture students learn many other things during their course of studies,both factual and otherwise.this is indeed unique since most other disciplines may not be able to claim the same about their courses of study.obviously,as a student ,one may acqire knowledge unrelated to the subject sthey study in the process of maturity and growing up in every discipline ,but most academics would not necessarily consider it a great achievement that their students have learned nothing in their discipline but other things during the course of study .In one year of studies in architecture at the University of Moratuwa in Sri Lanka in fact,quite the contrary was happening and the students took great pride that they are not leaning architecture lper se,at least in one year of their 6 year course.A recent research uncovered that the students believe they learned a great deal of "thinking"but very little in architecture.This paper examines a student evaluation of the t4eaching/learing practice that prevailed in the 5 th year studio in 1998 at the Department of Architecture at the University of Moratuwa ,which is a part of a lprogramme known as the Moratuwa Experiment and discusses its impact upon the student'thinking.Item INDO-LANKA development corridor:conceptual issues(Sri Lanka Institute of Architects.
