  • TCE Hot Spots have California Residents Concerned

    For years, many people living near the Moffett Federal Airfield by Mountain View, California, have had concerns over toxic chemicals known to be in the soil and groundwater in the area. After a recent report by the U.S. Environmental Protection Agency (EPA), some residents now admit to being scared. The EPA has found higher than expected levels of trichloroethylene, also known as ...

  • How Close to Contamination does a Property need to be for Vapor Intrusion to be a Concern?

    Cinnaminson, NJ, February 19, 2013 There are numerous sites across North America that have contaminated soil or groundwater due to manmade pollution.  Some of these sites have been a problem for decades and as communities have grown, more and more residential and commercial properties have been built above or near these areas. A major issue for properties built near these contaminated ...

  • Battery Storage will have a Profound Impact on Smart Buildings

    Often the best ideas are the most simple and elegant. If electric vehicles and consumer devices can have battery storage why can’t buildings? And if buildings can pull electricity from the grid at off peak times and store it in batteries, wouldn’t that save money? Since 2009, Stem based in California, have been working on these questions and disrupting the energy storage industry. ...

  • Adding Big Data and Analytics to the Smart Building Equation

    Continuing our series of articles on Innovation we talked to Dave Bartlett, Vice President, IBM Smarter Physical Infrastructure, about IBM’s vision for the Smart Building market and the key emerging technologies. There seem to be many definitions of ‘Smart’ Buildings. How do you define ‘Smart’ and what is IBM’s vision for this market? Is it just about reducing ...

  • NJDEP Vapor Intrusion Regulatory Changes: A Breath of Fresh Air

    On January 16, 2013, NJDEP released an update to its Vapor Intrusion Technical Guidance and updated its Vapor Intrusion Screening Levels. Screening levels are notably less stringent for a number of compounds, which have many of our clients sighing in relief.  For example, for tetrachloroethene (“PCE” or “PERC”) the groundwater screening level has been raised from 1 ...

  • Exergy indicators in the building environment

    The objective of this work is the application of the exergy analysis to the building sector and the introduction of suitable exergy indicators. The indicators are tools which are representative of the system under study and provide reliability over time, information to policy makers and awareness of potential environmental problems arising from human activities. The application of the exergy ...

  • Vapor Intrusion Issues Risk Occupants’ Health

    Vapor intrusion occurs when a gaseous substance migrates into a building.  For example, volatile organic compounds and other gases can migrate from contaminated soils and groundwater through cracks in foundations or sewer lines and enter a building.  Vapor intrusion can create an indoor environment that damages structural materials and puts building occupants’ health at ...

  • Plume Control under a City Building

    Subsurface remediation in a big city setting is complicated. Limited work space, heavy traffic, noise restrictions, and a dense network of utilities are just some of the factors that conspire to make the installation of any in situ plume control or plume reduction system a seemingly unsolvable logistical puzzle. Horizontal wells placed directly beneath a building can provide protection from soil ...

  • Soil Sampling under Buildings and Solving Vapor Intrusion using Horizontal Drilling

    The Issue: The New Jersey Department of Environmental Protection (NJDEP) mandated soil and groundwater sampling under an active pharmaceutical company manufacturing building in order to address vapor intrusion inside the building. Installation of vertical borings and wells through the building slab was not practicable without profound disruption of manufacturing activities inside the building. ...

  • Vapor intrusion pathway investigation

    The BEACON samplers defined the vapor intrusion of tetrachloroethene and 1,1-dichloroethene, while the Summa canisters (EPA Method TO-15) reported all non-detects. The BEACON survey enabled detection of some chemicals at levels below the Summa canisters practical quantitation limits providing a more complete and realistic vapor intrusion exposure pathway evaluation. Based on the defined vapor ...

  • Proposed PERC Ban Tabled Until 2026

    Landlord’s who may have been hoping for a boost from the NJDEP in their efforts to convince their dry cleaning tenants to switch from perchloroethylene (PERC) to alternative less toxic cleaning technologies, recently received a set back. The NJDEP retracted proposed regulations that have been under review for the last several years that not only mandated a switch to dry cleaning equipment ...

  • Strict Quality Assurance Procedures Ensure Reliable Vapor Intrusion Protection

  • Using bioaugmentation to reduce risks and costs associated with vapor intrusion

    The risk driver for remedial action on many sites is potential vapor intrusion hazard. While mitigation of the vapors entering the structure can reduce the risk to an acceptable level, there are associated long-term monitoring, operation and maintenance costs. Bioremediation of the source of vapors can reduce the risk and eliminate long-term costs. The vapor intrusion risk is managed by ...

  • New approaches studied to investigate vapor intrusion

    In 2008, EPA Region 9 received an EPA RARE grant (Regional Applied Research Effort) to evaluate three promising techniques for VI assessment of indoor air: (1) using radon as a surrogate for assessing VOC VI; (2) using modified sorbent-based methods for longer, time-integrated measurements of indoor air VOCs; and (3) using building pressure differentials to assess the potential for VI. Available ...

  • Vapor intrusion and indoor air quality due diligence during property transactions

    Vapor intrusion (i.e. the migration of volatile chemicals from contaminated soil and/or ground water through the subsurface into overlying building structures) as a contributing indoor air has become a growing concern for property owners and prospective purchasers in recent years as it can cause significant indoor air quality problems. This is largely due to the increased focus on this issue by ...

  • Grouping decomposition under constraints for design/build life cycle in project delivery system

    The design/build project delivery system has been adopted in the construction industry for many years. The numerous iterations of activities (tasks) can result in a hierarchical structure that reflects the life cycle of this type of delivery system. The Design Structure Matrix (DSM) approach has been used for simplifying complex project activities by clarifying the relationships between ...

  • Spray-applied gas membrane system instrumental in methane mitigation at Playa Vista

    The Playa Vista development, located near Marina Del Rey, California, has drawn political opposition over land-use issues and building safety concerns dating back to the 1990’s, which continued through the project’s inception in 2001. At the heart of the public safety concern was naturally occurring methane gas, which is known to be explosive if allowed to accumulate in confined ...

  • Methodology for calculating the energy consumption of air-conditioner in residential Building of China

    Increasing energy demand for building has made it imperative that energy conservation is an emergency in China. In this paper, calculation methodology on energy performance of residential building envelopes is studied by the Evaluation of Envelope Thermal Performance (EETP) index, the parameters related to EETP indexes are calculated from the eQUEST software. The formulae about energy performance ...
