Minimize Thermal Edge Losses with Stainless Steel Envelopes for Vacuum Insulation Panels (VIPs)

Feinerman A.D., Gupta P., Foster C., Yarbrough D.W., Kosny J., Thermal Conservation Technologies, US

Traditional Vacuum Insulation Panels (VIPs) have either a polymer/aluminum film or metallized polymer film exterior. In either case the VIPs are too fragile to be directly attached to a building’s envelope without a superstructure. The [...]

Evaluation of PCM-cardboard composite materials in dynamic thermal conditions

Musitelli M., Garbagnoli P., Diamanti M.V., Del Curto B., Pedeferri M., Politecnico di Milano, IT

In recent years, the use of smart materials to resolve environmental problems in building applications has been increasingly widespread. In particular, Phase Change Materials (PCMs) are used to improve thermal performance of air conditioning system [...]

Self-cleaning ability and cooling effect of TiO2-containing mortars

Diamanti M.V., Paolini R., Zinzi M., Ormellese M., Fiori M., Pedeferri MP., Politecnico di Milano, IT

This work focuses on the characterization of a self-cleaning and photocatalytic system for building façades, aimed at improving urban surfaces and the surrounding air quality, and decreasing energy consumption. Mortars containing anatase TiO2 nanopowders were [...]

Development of Innovative Packaging Characterized by Active Thermal Insulation Properties

Garbagnoli P., Altomare L., Del Curto B., De Nardo L., Del Curto B., Cigada A., Politecnico di Milano, IT

An innovative composite material based on cellulose matrix has been developed. Active thermal insulation properties have been conferred to the material through the integration of Phase Change Materials (PCM) into the matrix. Processing techniques of [...]

Sodium Clusters for a Superior Light Source

Gokturk H., Ecoken, US

Sodium lamp is one of the most efficient light sources providing an output of 150-200 lumens/watt; for comparison, light output of a fluorescent lamp is about 60-100 lumens/watt. Despite its efficient operation, sodium lamp is [...]

Performance and Potential Applications of Direct Expansion Ground Source Heat Pump systems for Building Energy

Omer A.M., University of Nottingham, UK

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasise has been put on utilisation of the ambient energy from ground source and other renewable energy sources. Exploitation of [...]

Technologies for Deep Reductions in Military Operational Energy Use

Brown R., Sharp T., Lindsey M., Kiser S., Andrews K., Lawrence Berkeley National Laboratory, US

The U.S. Pacific Command (PACOM) has begun a research program for Transformative Reductions in Operational Energy Consumption (TROPEC), which will identify, refine and validate technologies for reducing energy use in expeditionary military outposts. The primary [...]

Acoustic Power Recovery System for Thermoacoustic Cooling

Schwartz D.E., Garner S.R., Johnson J.R., Tuganov A.V., Palo Alto Research Center, US

In this work, we present a novel zero global-warming-potential, high efficiency thermoacoustic heat pump that can replace vapor compression systems for conventional air conditioning and refrigeration.

Passive and active Solar Systems for High Schools in Babylon- Iraq: Design and Economic Study

Al-Qaragouli A., Alguriny H., Ching O., Gibbs R., Coplen L., McKissack, US

In May 2011, the authors participated in the 2011 Renewable Energy Conference: “Supporting Sustainable Development for Iraq” sponsored by the Iraqi government with assistance from the U.S. Civilian Research and Development Foundation. The conference was [...]
