NILU.

One of NILU's main goals is to study the impact of pollution. It is thus very important for the institute to have control of the impact the institute¿s own activities may have on the environment and to reduce the impact as far as possible.

NILU has for many years been working to reduce the impact. In order to take this one step further, it was decided that the institute should restructure the work according to a relevant environmental standard and to seek certification according to the same standard.

The chosen standard is ISO 14001:2004 (Environmental management systems - Requirements with guidance for use) and NILU achieved certification according to this standard in October 2010. This report summarizes the results of the system.

Air quality in the National Museum of Art, Architecture and Design in Oslo. Measurement in the National Gallery and the Museum of Decorative Arts and Design in the period 2004-2013. NILU OR

Grøntoft, T.

The air quality in the National Museum of Art, Architecture and Design in Oslo, the National Gallery and the Museum of Decorative Arts and Design, was measured in several EU framwork program research projects in the period 2004-2013. The results from the measurements are reported and evaluations are made of the risk for damage to the museum objects due to the indoor environment, and of possible mitigating preventive conservation actions that could be implemented. The measurements did not show any critical environmental values, but some unwanted fluctuations, low values for relative humidity, and high values for climate, light and air pollution, which may be a risk for the conserveation of the objects. The relative humidity both in the National Gallery and the Museum of Decorative Arts and Design reached very low values in the winter (10-25%). This may constitute a risk for drying out and damage to organic materials such as textiles and paintings. The relative humidity in the National Gallery was strongly affected by the outdoor climate and in rain periods it could reach high values (values > 60 % were measured). This may constitute a risk for dimensional changes in and corrosion on objects, and possibly microbiological activity on surfaces. Quick fluctuations in relative humidity, that could cause dimensional stress and damage to objects, were measured in the Museum of Decorative Arts and Design. The light level in the Munch room in the National Galley was high and could damage tempera, oil paintings and more sensitive materials. The light levels in the Museum of Decorative Arts and Design were found to be acceptable. Concentrations of nitrogen dioxide infiltrating from outdoor, that could constitute a risk for damge to the obejects and materials, especially sensitive pigments and colourants, were measured in the exhibition rooms both in the National Gallery and in the Museum of Decorative Arts and Design. The air quality in the painting store room in the National Gallery was measured to be the same as in the exhibition rooms. The microclimate-frame that was used for a Munch painting in the National Gallery was found to protect this painting well against air pollution and UV-radiation, but gave little protection against the general light exposure, which was high in the Munch-room. The showcase, which was examined in the Museum of Decorative Arts and Design, reduced the fluctuations in the climate exposure of the exhibited objects and the concentration of air pollutants coming into the showcase from the room. The concentration of nitrogen dioxide in the showcase was still found to be higher than recommended and the modelling that was performed indicated that most of the nitrogen dioxide infiltrating into the showcase was deposited to the exhibited textiles. The exposure of the textiles to nitrogen dioxide constituted a risk for damage especially for sensitive colourants, but also for sensitive textils such as e.g. silk. Tightening of the showcase could have reduced the amount of nitrogen dioxide in it and the total negative effect of the air pollutants on the exhibited textiles. Possible installation of textile with activated carbon in the showcase could have reduced the amount of organic acids in a tighter showcase. A significant amount salt particles was measured to be present in the indoor air in the National Gallery. The sources were probably both windborne seasalt and deicing salts used around the building. Black particles that seemed to be deposited from the vetilation air was observed on the door and door case to the painting store room in the National Gallery.
