A survey of twenty residential buildings was conducted to observe the impact of ventilation strategies on moisture· accumulation in attics. The objectives of the survey were to record attic lumber moisture content levels over a period of one year and to assess the ventilation characteristics of the attics in order to account for the recorded moisture levels. The sample homes represented a range of ages, construction types and attic venting formats. Five of the houses were located in a coastal climate. Two test protocols, developed specifically for this project. were applied to the sample.
A review of published material covering small scale devices for measuring emission of volatile organic compounds (VOC) especially from building materials has been performed. The review is based on the international literature as well as patents, standard methods and devices for industrial application. Several small scale devices for emission measurements exist. A few of these devices are constructed for being attached directly to the surface of building materials on site. Stainless steel is the most frequently used material since the surface is smooth and inert.
