Don’t let the title mislead you. Rather than donning our swimsuits and catching some waves, we spent a few days at the Building Owners and Managers Association (BOMA) International Conference. This year’s event was once again well attended by real estate companies, building management organizations and suppliers who brought together cutting edge products for building operations and automation. The show floor was a maze of exhibits – from high tech energy savings applications to clean tech products and services. The constant whirlwind of visitors helped make it a successful show.

It was reported that AHSRAE’s 90.1, the energy standard for buildings, is being updated this year and will be released in the fall. The 2010 version will facilitate a 20+ percent increase in energy efficiency over the original 2004 version. While more research on construction materials and building envelope design makes it tougher to gain more energy efficiencies, this opens doors for new techniques and innovative products. Consequently, energy savings encompassed the theme of several technical presentations. Techniques, including advanced ventilation, are in demand as building owners seek new ways to reduce their building’s carbon footprint and improve bottom lines through energy cost savings. VOC reduction remains a priority for a healthier work environment, while VOC detection for demand controlled ventilation enables buildings to reduce energy consumption and control indoor air quality.
Not surprisingly, buildings are the primary consumer of energy worldwide, and it’s for this reason that the federal government developed a vision to reduce building energy consumption 30 percent by 2020. Industry advances like the ones seen at the BOMA conference are what will propel this vision forward. Cheers to energy efficiency and healthy air.

Have you ever asked your kids what they learned in school that day? Somehow, their initial answer tends to be, “Nothing.” Often, a little prying reveals that they did, in fact, learn something new. Perhaps they learned how to solve a difficult arithmetic problem, expanded their vocabulary or found out more about their country’s history. The truth is, children are curious and often eager to learn. Why let poor classroom air quality put a damper on their day?

Poor air quality in classrooms negatively affects academic performance and health – putting both student and teacher at risk. For many school districts, student absences lead to decreased government funding, while teacher absences lead to higher expenses. That’s pretty ironic if you ask us. We conducted a study of a typical classroom in Germany and found that the level of harmful volatile organic compounds (VOCs) in the classroom air exceeded healthy threshold limits within minutes after students arrived at 8:00 a.m. and exceeded those limits for the majority of the school day. Occupied classrooms are especially prone to high concentrations of bio-effluents (VOCs from human respiration, transpiration and metabolism). If left unchecked, VOCs can result in a variety of physical symptoms – eye irritation, headache, drowsiness or dizziness. Even though an increase in ventilation of just one-cubic-foot per minute can decrease absentee rates by up to two percent, very few classrooms have indoor air quality (IAQ) monitors. By signaling HVAC systems only when needed, the energy-efficient IAQ sensor helps maintain clean, healthy air so students can learn and teachers can teach.

AHR Expo, the show for HVAC&R industry professionals, saw a lot of traffic, especially for the first couple of days. Everywhere you turned, people were discussing air quality and VOCs. Since both are becoming such an issue, “source control” was a buzz word uttered by many attendants and exhibitors. Specifically, the term was referred to as a way to minimize the sources of VOCs, particularly in building materials, furnishings and coatings. Since these VOCs are toxic, ventilation rates need to account for their presence. Building automation was also a common theme at the show, as systems integrators brought forth new products to improve connectivity and efficiency in building operations. One such product was the IEQ monitor from BAPI, which is able to sense VOCs. Home automation was another popular theme, including zone control and smart appliances. Web-based devices are also arising within the industry for energy efficiency and at-home monitoring so that power usage may be tracked while residents are away from home.
