My interest in the use of building stones for teaching purposes began in the mid-1960s when I found samples of building stones in the rock collection of the Geology and Geography Department of Hunter College City University of New York.
Subsequently a sample of buildings was well selected after splitting the school building into homogeneous groups.
Based on a statistics study on considering structures, a reasonable sample of buildings has been selected as a representative of the great group of structures.
The Times did further analysis of a sample of buildings, and only a small fraction had been retrofitted.
Therefore, to balance the need for a representative study sample with the goal of building a supportive community partnership, we allowed 20 slots for Richmond volunteers and preserved 20 randomly selected Richmond slots.
Letters, samples of building materials, detailed plans, renderings and photographs of finished buildings are on view, along with a group of recent close-up shots of the 1913 Woolworth building, Gilbert's signature structure.
The objects on view range from personal papers to samples of building materials to detailed plans and presentation drawings of projects in process, along with renderings and photographs of finished buildings.
This paper presents the design of a more straightforward and compact version of the traditional Hot-Box apparatus (measures U-value) which instead determines the thermal resistance of samples of building envelope.
At first, a representative sample of 1,372 individuals (18+ years old, response rate 91.4%) were selected by random sampling of building blocks and households and by random selection of one adult individual per household.
Consequently, snowballing or chain-referral methods of building a sample are the preferred techniques adopted by researchers.
