    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.

    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.

    (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.
