Look at joint performance [PDF Full Text]

Search for:
Abstract: Analysis of several joints in service on actual buildings clearly demonstrates the value of the joint design principles which have been presented in many preceding Digests. Designers, through making their own examinations of joints in service, can increase their experience and gain greater confidence and capability for application of these principles to new work.

Coatings for exterior metal [PDF Full Text]

Search for:
Abstract: Coatings for use on common structural metals are described generically. The importance of surface preparation of steel and its influence on selection of primers are discussed. Exposure conditions, structural design and painting site are other factors considered. Coatings for zinc and aluminum are discussed in less detail.

Application of roof design principles [PDF Full Text]

Search for:; Search for:
Abstract: This paper gives an analysis of a conventional insulated roofing system over a concrete deck, and offers some suggested features for improved performance based on thermal and moisture considerations. A sloping, double-drained and vented system with the primary membrane below the insulation is described.

The metric system [PDF Full Text]

Search for:
Abstract: The Metric System is now in use in countries in which almost 90 per cent of the world's population live. Great Britain is in the process of changing over to the SI System, the modern version of the Metric System. This involves the use of six basic coherent units.

Reflective glazing units [PDF Full Text]

Search for:
Abstract: The shading coefficient, U-value, and light transmission factors for reflective glazing units are compared with those for ordinary windows and heat absorbing windows with and without inside shades. The luminous efficacy of the daylight transmitted through the reflective glazing units is shown to be considerably higher than for artificial light sources.

Admixtures in portland cement concrete [PDF Full Text]

Search for:
Abstract: Common types of concrete admixtures are discussed in relation to their prescribed uses and their secondary effects. Special attention is given to the problems which may arise in practice and the need for better knowledge, among users as well as producers, of the properties these products have on portland cement concrete.

Stack effect in buildings [PDF Full Text]

Search for:; Search for:
Abstract: Stack effect in a building depends on the difference in the temperatures of inside and outside air and the height of a building. The influence of stack effect is significant, particularly in tall buildings, during the winter seasons. This Digest describes the distribution of the total pressure difference caused by stack action across a building enclosure and interior separations and the many implications of the resulting air flow patterns.

Heating and cooling requirements [PDF Full Text]

Search for:
Abstract: This Digest discusses the nature of the heating and cooling requirements for buildings; how they depend upon climate, occupancy, and to a large extent the design of the building. The complexity of the air conditioning system, and both its initial and operating cost, depend on the nature of these loads. The building designer should take account of the interdependence of the building and the air conditioning system in order to arrive at an optimum over- all design.

The basic air-conditioning problem [PDF Full Text]

Search for:
Abstract: The control of conditions within a space by means of air conditioning is accomplished by the manipulation of heated and cooled air streams. The interaction of these air streams with the space and the occupancy, as discussed in this Digest, determine what is possible in the control of the thermal and air-quality aspects of the environment.

Stack effect and building design [PDF Full Text]

Search for:; Search for:
Abstract: This Digest discusses air tightness and the distribution of pressure differences resulting from stack effect in buildings as they are designed at present. It also discusses ways in which pressure differences and air flow may be modified to alleviate associated problems by varying air tightness characteristics or by the operation of mechanical air supply and exhaust systems.

Air conditioning processes [PDF Full Text]

Search for:
Abstract: The basic processes involved in treating air for comfort air conditioning are discussed. An understanding of these processes is expected to provide an appreciation of the general capabilities and limitations of different processes and to recognize the implications of the conditions specified in a particular building.
