Konferensbidrag (populärvet., debatt m.m.)abstract
- The EU-project ENV4-CT98-0796 MMWood has the following objective: To develop and validate for the SMEs an integrated Maintenance and management system for historic (wooden) buildings, adapted to the needs and purposes of various user group levels. The system will specifically contain - A documentation system for outer and inner parts of historic (wooden) building parts and components. - Soft- and hardware tools for the building inspection in the course of maintenance tasks, - an environmental risk factor assessment module, - a standardized maintenance assessment module based on complementation of the Wood-Assess process of assessing the symptoms, causes, effects, consequences, risks and remedial actions for environmental damages to the historic buildings and - a cost and maintenance planning module. In the project Damage Atlases for the following materials are given: Wood (including Surface Treatment), Adjoining Materials in Wood Constructions, Rendering, Brick and Natural Stone. These Damage Atlases use the same general layout, following closely the guidelines and protocol developed in a previous EU-project with the acronym "Wood-Assess". The general layout given for these damages is built up with the following questions: - Type of material; - Description of the symptom; - Investigation methods; - Condition degrees referred to pictures; - Extent of the symptom; - Possible causes/degradation agents; - Total condition degree; - Consequences and risks; - Recommended actions. In this paper the general layout of these Damage Atlases is extensively described and included are also some examples of the treated damages. These Damage Atlases are also put into the PC-based maintenance and management system developed in the same project (a first version was developed in the Wood-Assess project ENV4-CT95-0110, which was reported in some detail in the previous CIB congress in Gavle).

A PC based system for maintenance management of buildings : General description
- 2001

Konferensbidrag (populärvet., debatt m.m.)abstract
- Europe's rich culture in wooden buildings are rapidly degrading due to environmental impact, wrong conservation techniques and lack of resources and technological tools for appropriate conservation. These issues were addressed in the former EU-project ENV4-CT95-0110 Wood-Assess , which has been finalised (Haagenrud et al, 1999). In a new EU-project MMWood (ENV4-CT-98-0796) a PC-based system for maintenance management of buildings has been developed. The project had the following objectives: To develop and validate for the SMEs an integrated Maintenance Management system for historic buildings, adapted to the needs and purposes of various user group levels. Based on the Wood-Assess concept and results the modular GIS (Geographical Information System) based system, MMWood, will specifically contain - A documentation system for outer and inner parts of buildings and components; - Soft- and hardware tools for the building inspection in the course of maintenance tasks; - An environmental risk factor assessment module; - A standardized maintenance assessment module; - A cost and maintenance planning module. Main developments from the Wood-Assess project are the inclusion of the maintenance management phase, extension of the damage atlas to include also adjoining materials in wood constructions, rendering, brick and natural stone, and a fully integrated field inspection system, allowing the user to import/export all background and recorded data between the field inspection and the total maintenance management system.

MMWood Environmental risk factor module

Konferensbidrag (populärvet., debatt m.m.)abstract
- An environmental risk factor assessment module was elaborated as a part of the EU-projectMMWood (ENV-CT98-0796). The Environmental Risk Factor may be an important aid in providingnecessary data for predicting service life for buildings or building elements.The objective of the work package was to provide and synthesise the necessary environmental data forexploiting the service life functions established elsewhere and the methods and models developed inWoodAssess.In WoodAssess (presented at the previous CIB congress in Gävle) the methodology for assessing andmapping environmental risk factors and areas for wood on regional, local, and micro scale in Europewas demonstrated. The methodology is developed further, and more materials used in connection withwooden houses, like stone, bricks, rendering, painted rendering, and painted wood, are now included.Environmental data, as climatic and pollution data are collected for different regions in Europe. Thedata are either from meteorological stations or as geographical data (GIS) from simulation modelsbased on emission data. Meteorological data from measurements are also transformed to geographicalinformation. By use of the environmental data and service life functions the expected service life iscalculated for each object/region and material.A reference situation, defined by cold climate and unpolluted air, is used to calculate the referenceservice lives. From this the percentage reduction in service life can be calculated for eachobject/region and material.By use of the meteorological data, combined with geographical information as topography, sunny andshaded areas, a Scheffer's Climatic Risk Index (SCRI) for potential wood decay was calculated forobjects and regions. Better digital maps combined with models for precipitation, temperature andrelative humidity will form a proper basis for a more detailed modelling of SCRI.In this paper the methods for assessment of environmental data and service life are presented, and theresults as calculated service life and reference levels are included. Service life is presented both assingle values and as geographical information (GIS) on different geographical scales (local andregional scale).
