An automated tool for evaluating compliance and providing assistance with building energy standards during design
In an effort to encourage the maximum cost-effective level of energy efficiency in new building design, energy-efficiency standards have become more location-specific and performance-based. As a result, standards often provide more than one path for ensuring and demonstrating that a design complies, but at the cost of increased complexity. In addition, the burden of remedying a noncompliant design rests on the designers' knowledge and experience, with only general guidance provided by the standards. As part of efforts in the US Department of Energy's (DOE's) Advanced Energy Design and Operation Technologies (AEDOT) project, a team at DOE's Pacific Northwest Laboratory is developing a computer program known as the Energy Standards Intelligent Design Tool (ES-IDT). The ES-IDT is one component of a prototype computer-based building design environment. It performs automatic compliance checking for parts of ASHRAE/IES Standard 90.1-1989 and provides designers assistance in bringing noncomplying designs into compliance. This paper describes the ES-IDT, the functions it provides, and how it is integrated into the design process via the AEDOT prototype building design environment. 9 refs.

Photoinitiated electron transfer in multichromophoric species: Synthetic tetrads and pentads featuring diquinone moieties
This project involves the design, synthesis and photophysical study of complex molecular systems engineered to achieve long lived charge separated states by a biomimetic, photoinitiated multistep electron transfer process. The use of these artificial systems to investigate different electron and energy transfer strategies will allow the evolution of more efficient molecular devices for the gathering of light energy and its transformation into chemical potential energy. The three major aspects of the work emphasized in the initial proposal are: design and synthesis of molecular devices incorporating new quinone moieties, synthesis and spectroscopic studies of molecular tetrads and pentads featuring modified porphyrin-diquinone linkages, and new photochemical and photophysical investigations of tetrads and pentads, including the development of methods for harvesting the energy stored in long-lived charge separated states.

Hydrogen Separation by Ceramic Membranes in Coal Gasification
Project Objectives are to develop hydrogen-permselective ceramic membranes for water-gas shift membrane-reactor suitable for hydrogen production from coal gas and evaluate the technical and economic potential of the membrane-reactor. During the reporting period exploratory experiments begun on a membrane preparation technique aimed at providing higher membrane permeance. The new preparation technique involves two stages. The first stage is the formation of a layer of silica gel by a two-phase interfacial reaction within the pores of the substrate. The gel is then dried and calcined yielding a microporous (pore diameter below 10 [Angstrom]) silica layer within the pores of the substrate tube. The second stage involves one-sided chemical vapor deposition using the SiCl[sub 4]-H[sub 2]O reaction to close up the micropores of the gel layer and produce the final hydrogen permselective membrane. Chemical reactions involved are described.

Thermal spallation drilling. Final report
Work that was performed on a previous contract with the Los Alamos National Laboratory and subsequent work at NM Tech indicated that an intermittent heating and cooling cycle, produced by heating with the conventional blast from a small jet engine and then cooled with a stream of water, would prove to be successful in spalling additional rocks. New Mexico Tech has attempted to further the use of spallation drilling to suit applications for mining and oil and gas drilling by showing that the use of a heating and cooling system would successfully penetrate otherwise unspallable rocks. This process, while showing some success in previous experimentation, has proved to work only spasmodically. The rocks tested had zones that were not spallable or were so slowly spallable that non-uniform holes were produced. Because of these irregularities, further field experimentation is not now profitable.

Development of a reburning boiler process model. Second quarterly progress report, January 1, 1992--March 31, 1992
The overall objective of this program is to integrate Energy and Environmental Research expertise in boiler reburning performance evaluation into a package of analytical computer tools. Specific objectives of the program are to develop a computational capability with the following features: (a) can be used to predict the impact of gas reburning application on thermal conditions in the boiler radiant furnace, and on overall boiler performance. (b) can estimate gas reburning NO{sub x} reduction effectiveness based on specific reburning configurations and furnace/boiler configurations. (c) can be used as an analytical tool to evaluate the impact of boiler process parameters (e.g., fuel switching and changes in boiler operating conditions) on boiler thermal performance. (d) is adaptable to most boiler designs (tangential and wall fire boilers) and a variety of fuels (solid, liquid, gaseous and slurried fuels). (e) is sufficiently user friendly to be exercisable by engineers with a reasonable knowledge of boilers, and with reasonable computer skills. Here, ``user friendly`` means that the user will be guided by computer codes during the course of setting up individual input files for the boiler performance model.
