Reporting
An appropriate schedule for reporting shall be established by the contracting organization and strictly adhered to. The schedule shall include no less than monthly summary reports and complete phase reports as each full segment of the program is completed. The monthly summary reports shall be documented with examples of the photographic records for each phase of the work completed during that month.
Advisory Council
The organization performing the testing work in this program shall set up a procedure to work with an Advisory Committee representing the parent group.

1.0 MASONRY: Thermal design techniques for masonry structures.
2.0 STATEMENT OF NEED
The energy crisis, and the current trend in building energy regulations resulting therefrom, make it necessary for those involved with building design and construction to evaluate more precisely the thermal performance of building envelopes. Commonly used analytical methods for thermal design, which assume steady-state temperature conditions, result in the implication that adding more and more insulation to the building envelope is the most effective and efficient way to conserve energy. These methods are reported to be quite inaccurate for thermal design and therefore are not adequate for today's needs.
Sophisticated thermal design methods, which accurately account for the effects of such variables as dynamic conditions and thermal mass, have been developed, but these methods require the use of computers, are costly to use, and are not easily available to many practitioners.
Research programs are needed which will:
1) Assess the potential of selective absorptive and emissive coatings for application to masonry walls used for thermal storage. Safety and durability of the coatings should be assessed.
2) Evaluate the use of high heat capacity and high heat-transfer materials using masonry products or the masonry encapsulation technique.
3) Develop a simplified procedure for thermal design of buildings so that the designer may accurately predict energy requirements of certain buildings.

2.0 STATEMENT OF NEED
There has been significant masonry research conducted in the United States and other parts of the world. Results of much of this research, however, have not been widely disseminated. The Advisory Council, in order to eliminate duplication and to extend the areas of research, recognizes the need to accumulate a complete summary of all com-
