The Emerging Role of VRF Technology in Commercial Buildings

This session discuss variable refrigerant flow (VRF) technology, a heating and cooling solution that is quickly being adopted in Maine schools and commercial buildings. The technology is exciting because these systems can simultaneously and efficiently heat and cool different parts of the building by taking waste heat captured in one part of the building and delivering it to spaces that need heat. The program will cover the kinds of buildings and situations where variable refrigerant flow systems are appropriate, costs and benefits of VRF systems, and things to consider when choosing between VRF and other systems like a multi-zone high-performance heat pump.

Indoor Air Quality: How Ventilation is Critical to Improving the Human Condition in the Indoor Environment

As we continue to build tighter, more heavily insulated homes, we are learning that significant levels of air pollutants can be trapped inside. With Americans spending approximately 90 percent of their time indoors where the air quality can be up to five times worse than outdoor air, we must design effective ventilation systems with trusted, accurate product performance. Presenter will explain why you should be concerned and what you can do to ensure healthier homes, including selecting certified ventilation products.

Talking Mushrooms

Effective communication is tough, but it’s even more so in the unstandardized, moldy world. Fungi in the indoor environment is complex, and there is a great deal of both good and bad information published. This can make communicating and acting on what is “generally accepted” for mold projects difficult. In this presentation, we will identify what is known about the biology of fungi, how it applies to our buildings and health, and some basic, good scientific practices that can be used. We will then apply this knowledge through the use of various communication techniques to demonstrate how IAQ information can be conveyed in an understandable manner.
