,Case Study Project Exeter Library4243323,Exeter LibraryLouis Kahn,“Inspiration is the feeling of beginning as the threshold where Silence and Light meet.Silence,the unmeasurable,desire to be,desire to express,the source of new need,meets Light,the measurable,giver of all presence,by will,by law,the measure of things already made,as a threshold which is inspiration,the sanctuary of art,the Treasury of Shadow.”“No space is really an architecture unless it has natural light.”“Evenaroom which must be darkneeds at least a crack of light to know howdarkit is.”“A great building,in my opinion,must begin with the unmeasurable,go through measurable means when it is being designed,and in the end must be unmeasurable.”“I see the library as a place where the librarian can lay out the books,open especially to selected pages to seduce the readers.There should be a place with great tables on which the librarian can put the books,and the readers should be able to take the book and go to the light.”If you were given the first commission before libraries were ever built to build a place where these books can be,what would you do?That is the thought you have about its nature when you are given the privilege of designing a building.There could be indecision as to what a library is.It depends on how much you love the book,how much you think it should not taken out and its being so precious that nobody disturbs its location.”,Exeter Library design philosophy,Jan-May and Sep-Dec need heatingJune-Aug can be free runningLocation:Exeter,New HampshireLatitude:43 Summer solstice:70

design development,Exeter Library sections,Exeter Library scale analysis,Exeter Library research questions and methodologies,TopicThe Environmental performance of light and heat in Exeter library by louis kahnObjectivesThe daylight performance in the building in different areas including the atrium,book collection area and the reading area.The potential thermal problem in the reading area because of the full glass when it is free running.The energy consumption to keep the temperature in the mechanic building.Research questions How would the side faade and atrium work together to achieve the designed luminosity?What is the impact of glass faade on the thermal environment in the reading area?AssumptionThe atrium can benefit from the roof light and the book collection area can not benefit because of the book need to be protected from the daylight.It may experience overheating in the hot summer because of the full glass and it may cause the heat loss in winter.MethodologyComputer
