Some important facets of hydronic-system design and function that design engineers and building owners should be aware of to create a total system approach are discussed. These facets include first cost, life-cycle cost, annual efficiency, and value engineering. Equipment configuration includes using a modulating condensing boiler to handle the low-temperature startup and circulation phase, then shifting heating and circulation to less expensive, non-condensing systems for routine heating. When life-cycle calculations are completed, a mixed installation of condensing and near-condensing boilers is the most cost- effective solution. Every packaged boiler design must be tested to government standards for its nominal efficiency to be determined. Another important factor is proportional-integral-derivative (PID) controls that sample changes over time. A standard boiler without outdoor reset control will modulate down while operating at high temperatures.

New initiatives to house chronically street homeless (CSH) adults have led to increasing proportions of this population living in congregate supportive housing, but little is known about the impact of this shift on supportive housing programs. The present multisite, mixed-methods study examined service utilization and lease compliance among 52 chronically street homeless and 46 long-term shelter stayer (LTSS) adults during their first 12months in congregate supportive housing. Quantitative analysis of administrative data revealed that CSH tenants used significantly more service resources than LTSS tenants, including more advocacy, escorting, and psychiatric treatment and more assistance with financial, housing, and mental and physical health issues. The 2 groups did not differ significantly on measures of lease compliance. Qualitative focus groups with CSH tenants, service provider staff, and property management staff all indicated that existing supportive housing services are suitable for this population, although some adjustments, additional resources, or both, may be indicated. © 2012 American Orthopsychiatric Association.

The features of a thermal-storage system coupled with radiant cooling for commercial facilities that were exhibited at ISH 2011 in Frankfurt, Germany, are discussed. Cold night-time air is blown through a cooling tower. The resulting cooled water is moved through a plate- and-frame heat exchanger and circulated through cross-linked-polyethylene (PEX) tubing attached to the underside of floor slabs. Chilled ceilings have a fairly low cooling capacity of 20 to 30 Btuh per square foot. Passive chilled-beam systems, on the other hand, have a cooling capacity approaching 150 Btuh per square foot, while active chilled-beam systems have a cooling capacity approaching 400 Btuh per square foot. An alternative to conventional variable-air-volume (VAV) systems, chilled beams circulate chilled water through tubing embedded in a metal ceiling fixture to wick away heat. The business end of a chilled beam is made of copper tubing bonded to aluminum fins. The beam is housed in a sheet- metal enclosure typically placed at ceiling level.

Heidelberg United Church of Christ in York needed a mechanical fix in their heating equipment. Dave Yates, president of F.W. Behler, Inc. was given the contract to handle the situation. Yates' plan included converting the sanctuary's steam radiators to hot water, requiring several new, compact modulating condensing hot-water boilers. Remaining portions of the church would be served by a new, properly sized steam system. Yates also planned to provide A/C to the entire, non-ducted building with ductless Fujitsu mini-split systems. A 12,000 Btuh evaporator unit was installed; one of three that are connected to a 2.5-ton, triple-zone condensing unit outside. The other two evaporators, at 9,000 Btuh each, were installed in the nearby restrooms. Large capacity, three-ton units were installed to throw air over large distances; a requirement for the 5,000 sq ft, 65-ft high sanctuary.

Advanced hydronic equipment provides efficiency and system flexibility in the construction of larger buildings. The newest generation of hydronic equipment, such as condensing technology that extracts heat from condensate, recovers heat for hydronic use, pushing combustion efficiency into the 95- to 99-percent range. Additionally, hydronic equipment can be fitted with new and sophisticated controls and integrated with a building-automation system (BAS). Additionally, more-sophisticated controls can sample modifications over time and learn a system's responses to changes in conditions. Advanced boiler electronics likely will become self-diagnostic and understand what steps should be taken to fix the problem. Variable-speed pumps, including close-coupled, vertical Inline variable-frequency drives (VFDs), and larger base-mounted, end-suction pump lines, offer a broader range of performance for jobs that demand varying fluid pressures and volumes.

The project team is developing a prototype of InfoWriter, a Web 2.0 concept mapping tool and writing environment to support students in writing informational and explanatory texts. The product will be used in middle and high school English Language Arts classrooms, and others as appropriate, to supplement traditional writing assignments. Pilot research in Phase I will seek to demonstrate that the software prototype functions as planned, teachers are able to provide feedback via the platform and integrate it within the classroom environment, and that students are engaged with the prototype.

School-level curriculum design and instructional delivery is often traditional, not incorporating highly interactive, multimodal social media technologies where users generate content to provide feedback for learners and to support formative assessment. This project team will develop key elements of today’s Web 2.0 social networking technologies to include the potential for collaborative content design amongst teams of teachers, easy dissemination of instructional content to students, and rapid, responsive formative and summative assessments of student work. The product, the Learning Element 3.0, will be the equivalent of Facebook for educators while focusing on professional rather than interpersonal interaction. The product will be framed to interconnect learning design, learning content delivery, learner activity, and learning assessment. The tool will consist of three closely interconnected online spaces, which users will choose to view separately or juxtapose in side-by-side panes presenting parallel views. These spaces will include: 1) a ‘teacher resource’ space in which lesson planning occurs; 2) a ‘learner resource’ space in which this plan is translated into student-accessible text for independent or semi-independent learning; and 3) a ‘learner workbook’ space in which students undertake activities in the ‘learner resource’ space that build on scaffolded reading activities completed in the ‘learner resource’ space.

In recent years there has been considerable public concern about the state of writing – a threshold skill for academic achievement, employment, and participation in today’s world. This project team will create a new technology tool designed to improve student writing performance and the usefulness of writing assessments. U-learn.net will be an online environment that will combine social networking and semantic tagging technologies to give learners constant feedback in the form of on-demand formative assessment. The ‘u’ of the u.learn tool stands for ‘ubiquitous’ or the idea that social networking technologies allow the social relationships of learning to continue beyond the classroom and traditional school day.
