Incorporating Third Party Green Building Rating Systems into Municipal Building and Zoning Codes

The role of green buildings in mitigating climate change has thus become a hot topic. This literature has begun to elicit change within corporations pursuing third party certification of their corporate buildings and campuses. Perhaps the success of discrete green building projects in mitigating climate change compared to the failure of international regulatory bodies to reach consensus for meaningful change is due to the publicity and, in turn, profits associated with certification by a third party green building rating system. In addition to reduced GHG emissions, reduced runoff, reduced maintenance costs, and positive publicity of green buildings for the project developer, green building rating systems also stimulate local commerce and tax revenue streams for municipalities. Additionally, green building rating systems combat greenwashing and ignorance in the marketplace amongst consumers who try to make informed and responsible decisions but do not have the resources to research the validity of claims that a product or building is sustainable. In brief, while municipalities can take actions to realize these benefits, there are right and wrong ways to go about the adoption of third party green building systems, and cities that do not navigate their course wisely will see their legislation stricken down and their intentions frustrated by the courts

Evaluating the Efficacy of an Attachment-Informed Psychotherapeutic Parenting Program for Incarcerated Parents

An attachment-based, psychotherapeutic parent education course was created for incarcerated mothers and fathers to improve their ability to provide positive parenting and a more stable home environment for their children. The current study assessed the effects of this parenting curriculum on parents’ tendencies to be abusive, their sense of efficacy and satisfaction as a parent, their psychological distress, and their knowledge of child development and positive child guidance strategies. Results of pre-post assessments showed a significant improvement in parents’ sense of efficacy and satisfaction in the parenting role; their knowledge, skills, and behavior as a parent; their understanding of child development; their knowledge of alternatives to using corporal punishment; establishing appropriate parent-child boundaries; and they were less likely to view their child’s independence as a threat. Females showed a significant decrease in distress symptoms. Results are discussed in terms of the critical need for effective, high-quality parent education to break the intergenerational cycle of poor parenting for this at-risk population

Performance investigation of a high-field active magnetic regenerator

Regenerative magnetic cycles are of interest for small-scale, high-efficiency cryogen liquefiers; however, commercially relevant performance has yet to be demonstrated. To develop improved engineering prototypes, an efficient modeling tool is required to screen the multi-parameter design space. In this work, we describe an active magnetic regenerative refrigerator prototype using a high-field superconducting magnet that produces a 100 K temperature span. Using the experimental data, a semi-analytic AMR element model is validated and enhanced system performance is simulated using liquid propane as a heat transfer fluid. In addition, the regenerator composition and fluid flow are simultaneously optimized using a differential evolution algorithm. Simulation results indicate that a natural gas liquefier with a 160 K temperature span and a second-law efficiency exceeding 20% is achievable

Passive force balancing of an active magnetic regenerative liquefier

Active magnetic regenerators (AMR) have the potential for high efficiency cryogen liquefaction. One active magnetic regenerative liquefier (AMRL) configuration consists of dual magnetocaloric regenerators that reciprocate in a persistent-mode superconducting solenoid. Issues with this configuration are the spatial and temporal magnetization gradients that induce large magnetic forces and winding currents. To solve the coupled problem, we present a force minimization approach using passive magnetic material to balance a dual-regenerator AMR. A magnetostatic model is developed and simulated force waveforms are compared with experimental measurements. A genetic algorithm identifies force-minimizing passive structures with virtually ideal balancing characteristics. Implementation details are investigated which affirm the potential of the proposed methodology

Review on the developments of active magnetic regenerator refrigerators – Evaluated by performance

© 2020 Magnetic/magnetocaloric refrigeration is an energy-efficient and environmentally safer cooling technology with the potential to be an alternative to conventional vapor compression systems in the future. Magnetocaloric effect (MCE) is a measure of relative temperature rise/drop of certain ferromagnetic materials upon the application/removal of a magnetic field. The technology uses MCE of some materials such as Gd to produce temperature difference/span relative to the ambient via a four-stage regenerative cycle known as active magnetic regenerative (AMR) cycle. Research in this area has been thriving especially during the last two decades focussing on different aspects of technology such as materials, magnetic field sources, and system design. On the system design, studies investigating the effect of different magnetic, thermal-hydraulic, and geometric parameters on the performance have been found in the literature. The present work offers a chronological review and comparison of recent advances in AMR refrigerators. Findings and results reported in the literature are compared in terms of magnetocaloric materials, geometric parameters (such as regenerator geometry); operating parameters e.g. cycle frequency, utilization, heat transfer fluid, heat rejection temperature, and cooling load, etc. Besides, performance indicators such as no-load temperature span, cooling capacity, and/or system coefficient of performance have been considered. Parametric sensitivity and performance trends have been identified and discussed. Major barriers to achieving system peak performance and hence the marketability of the technology are also highlighted
