During this seminar we will discuss the design and operational characteristics of a geothermal HVAC system. We will explore the different configurations of a geothermal system including standing column, horizontal loop, vertical loop and pond loop systems. We will compare geothermal HVAC systems with conventional HVAC systems relative to first costs, operating costs, functionality and maintenance focusing on commercial buildings.
Learning Objectives:
-Develop an understanding of how a geothermal heat pump system operates.
-Have the ability to assess if a building is a candidate for a geothermal heat pump system.
-Understand the environmental, operational and cost benefits of a geothermal heat pump system.
Homeowners with natural gas water heaters have difficulty justifying the expense of a more efficient condensing heater. Combination space and domestic hot water systems bundle together the two loads, which saves energy and makes them more cost-effective. These systems also help eliminate combustion safety concerns.
Historically, mechanical contractors have custom engineered and pieced together combi systems in the field, paying little attention to efficiency and optimization. But condensing heating plants will only reach their energy saving potential when all components are designed and installed correctly.

An innovative technology to increase the heater capacity without increasing the coil side pressure drop in fired heaters.
Furnace Improvements has implemented this technology in many fired heaters around the world. This technology is useful specially for Reformer heaters as coil pressure drop is limited for those heaters, typically 2-5 psi.
Improve fired heaters performance and reliabiltyAshutosh Garg
Fired heaters are often suffering from high tube metal temperatures and short run lengths. Operators are always worried about hot spots in the furnace. While refineries want to push the heaters hard, the heater starts coking up and very soon, the heater tubes have to be cleaned.
FIS has done extensive research and CFD modelling of heaters in the recent time and has concluded that localized burner flame and hot flue gas currents are responsible for the hot spots on the tubes. FIS has now developed a new patented technology for solving hot spot problems. This technology called Inclined Firing Technology involves orienting the burners at an angle on the floor / wall/ roof to direct the flame away from the tubes. The results of this technology have been extremely good and with a very low investment, the reliability and run length of the heater is improved significantly.

This report is a joint effort of member organizations of the Child Proofing Our Communities campaign’s Healthy
Buildings Committee. Child Proofing Our Communities is a locally-based, nationally-connected campaign formed to protect children from exposures to environmental health hazards in or near public schools.
Buildings produce half of all greenhouse gases and account for one-sixth of the world's
freshwater withdrawals, one-quarter of its wood harvest and two fifths of its material and
energy flows. One in three buildings in this country, according to the USEPA, has less
than healthy indoor air quality. By several estimates, we will double the size of the built
environment over the next twenty to forty years. For these reasons there is a critical and
immediate need to shift thinking on how the built environment is designed. To reduce
environmental impact, protect public health and improve environmental equity and
justice, we must change principles for building practice. Designers in general and
architects in particular should play a high profile leadership role in this transformation.
This document is the final rebuttal, filed by the Center for Maximum Potential Building Systems and the Healthy Building Network, in response to the U.S. Green Building Council’s invitations for comments on proposed Materials Credit 9 for LEED™ Commercial Interiors. The document, consisting of five independent papers , identified as Section I-V and 4 supporting documents identifed as Attachment 1-4, specifically responds to initial position papers and rebuttals submitted by the Vinyl Institute and other parties on November 3, 2000 and November 20, 2000, respectively.

A Subversive Little Book “This is a book by people who like cities.” Thus began William H. Whyte Jr.’s introduction to a subversive little book with the polemical title The Exploding Metropolis: A Study of the Assault on Urbanism and How Our Cities Can Resist It (Editors of Fortune 1957, hereinafter cited as TEM). Drawing on a roundtable of urban experts convened by two prominent magazines, Fortune and Architectural Forum, the book in six short essays reexamined the nature of cities and city building in the postwar era. The book also defi ned future agendas for “Holly” Whyte (as he was fondly known by his friends) and fellow editor Jane Jacobs.
In his State of the Union, President Obama laid out his vision for winning the future by investing in innovative clean energy technologies and doubling the share of electricity from clean energy sources by 2035. Alongside that effort, the President is proposing new efforts to improve energy efficiency in commercial buildings across the country. –WhiteHouse.gov

Cradle to Cradle® Certification is a multi-attribute eco-label that assesses a product’s safety to humans and the environment and design for future life cycles. The program provides guidelines to help businesses implement the Cradle to Cradle framework, which focuses on using safe materials that can be disassembled and recycled as technical nutrients or composted as biological nutrients. Unlike single-attribute eco-labels, MBDC’s certification program takes a comprehensive approach to evaluating the sustainability of a product and the practices employed in manufacturing the product. The materials and manufacturing practices of each product are assessed in five categories: Material Health, Material Reutilization, Renewable Energy Use, Water Stewardship, and Social Responsibility. Click here for complete description of Certification Criteria .
Tish Tablan will deliver a presentation on the Cradle to Cradle® framework and how building professionals can use it to create more sustainable buildings. This webinar provides 1 GBCI CE for LEED Credential Maintenance.
As the flagship project for the next downtown Boston neighborhood slated for growth, Atlantic Wharf will be the city of Boston’s first LEED Gold mixed-use development. CBT Architects presents a case study on this new one million square foot project that includes approximately 65 residential units, ground-level retail and public spaces, six stories of below-grade parking, and 31 floors of office space that will bring urban activity directly to the Fort Point Channel water’s edge.
The new sustainable development is at the base of a series of restored and renovated historic structures that preserve the texture and streetscape of this site, integrated with a modern highrise glass tower. By preserving the south and east façades of the historic warehouses, using a very energy-efficient curtainwall, and employing green roof technologies, Atlantic Wharf will be the a centerpiece of Boston's green development.
