S-MATRIX Efficient Energy Use Systems

At S-MATRIX, our more recent work has primarily been in hardware, software, computers, electronics and instrumentation.

However, it is in the field of efficient energy use that we are better known internationally. In the early 1980’s we published (see Publications below) some of our unique design procedures in international journals such as "Energy" and "Solar Energy". Using mathematical modeling techniques, handheld calculators and PCs, we replicated and superceded the mainframe computer simulation work of groups such as the US Energy Research Institute, the Los Alamos Laboratories, University of Wisconsin, University of Waterloo and Colorado State University. Our publications were in the area of solar heating and cooling systems, passive solar energy and seasonal storage. Our methodology for modeling these systems including annual hourly temperature and solar radiation data, and building configuration and device parameters, however, is generic. The techniques which reduce computing times conservatively by factors of 10 to 100 can equally well be applied to other types of active and passive energy conserving devices, including, but by no means limited to photovoltaics, building energy management and water source heat pumps. The results of our system performance analysis are in a form that is particularly useful for life cycle cost analysis (which is one of the final tests of efficient energy design). We have had many projects in efficient energy use systems since then. However, because energy in North America has been relatively cheap and abundant, local contracting and consulting opportunities and projects have dwindled in the intervening years. We look forward with enthusiasm to more work in this field as the world continues to develop a better appreciation of how important it is to use all of our non-renewable and renewable resources with greater care and understanding.
