Tidskriftsartikel (populärvet., debatt m.m.)abstract
- The structure of Swedish research finance was radically changed in 2001, and the present goals of research policy are that Sweden is to be a leading research nation, where research with a high scientific quality is conducted. However, the process of internationalizing Swedish building research leads to an issue of how international standards for scientific quality are applied and how Swedish researcher participation in industry initiatives and European framework programmes is supported. This issue is discussed against a background of a national system where research funding is indirectly and strongly linked to university teaching, which also means that research institutes are comparatively unimportant. International expansion of large firms in the construction industry has led to an increasing engagement with university research. However, the current process intended to guarantee high scientific quality in projects with national funding is inflexible and not fully compatible with what is required for industry and European research cooperation.

- The EU project Smart-ECO brings together experienced organizations spanning the full range of stakeholders covering the area of sustainable building. These include universities, R&D organizations, companies developing, supplying and using innovative technologies, consultants, users, government and policy makers. Smart-ECO uses this core partnership together with a wider stakeholder group community to focus on global issues of sustainable building to identify and evaluate priorities for current and future RTD activities. Activities and policies are due to be mapped to identify gaps and to focus future efforts. Innovative technologies, as well as improvements of the construction process, and their introduction into the building sector will be considered in relation to sustainable development, life performance, ambient intelligence, and other relevant stakeholder concerns.The project focuses on routes and means to enable the uptake of efficient technological and non-technological innovation that in turn enable the building and construction sector to meet the requirement for sustainable building. The current situation and the vision of a more sustainable built environment sets the frame for the appreciation of the long term effectiveness of Eco-buildings and innovative technologies, especially renewable energy systems. Together, the vision and relevant EC policies will serve as a reference framework for the analysis of life performance aspects of innovative technologies applied to realise more energy efficient and more sustainable buildings.This paper presents and discusses the process of establishing a reliable vision for sustainable buildings and related performance requirements.

Durable and robust vacuum insulation technology for buildings
- 2011

Konferensbidrag (refereegranskat)abstract
- Vacuum insulation panels (VIPs) provide unprecedented opportunities for obtaining excellent thermal insulation with light and slender constructions. This article discusses the performance over time of VIPs, and the possibilities to overcome the current problems related to fragility and limited durability. Aerogels are together with fumed silica among the most competitive core materials for VIP's. The use of classical aerogels, as produced in autoclaves is, however, limited due to the high production costs. The fumed silica on the other hand requires vacuum levels that are difficult to maintain with the currently available vacuum envelopes. A material with comparatively smaller pores will on the other hand allow obtaining low thermal conductivity at higher pressure (less vacuum) and will therefore reduce the pressure difference over the envelope. There is therefore much to be gained by reducing the pore size. New cost and performance efficient silica aerogels offers opportunities to enhance the properties of the panels by customizing the pore structure and pore size distribution. Building technologies and how the panels are applied in a manner that improves the structural, thermal and hygroscopic performances of vacuum insulated constructions have been studied and are discussed.

CIB W106 Geographical Information Systems : Work Period Report
- 2005
-
Ingår i: 10th International conference on durability of building materials and components.
-
Konferensbidrag (refereegranskat)abstract
- In the building and construction sector all features are location based. The world of geographic information and application orientation is moving extremely fast, thus challenging the building sector to facilitate and implement this new technology and applications. In order to deal with these issues CIB in 1996 established the task group CIB/TG20-GIS. Based on the report CIB 256 from this group and its recommendations, CIB in 2000 established the working commission CIB W106 - Geographical Information Systems., with the overall objectives to provide an international platform for R&D of GIS applications for the built environment, and to promote and encourage the use of GIS in the building sector. The W106 has members from 14 countries/organisations and will present its final report for work period 2001-04 due for the 10DBMC conference in 2005. The work is divided into the following four Tasks: TG1- GIS-requirements and availability of geographic standards-, -data and infra -structures, TG2- GIS-based analysis and modelling of flow and distribution of materials in the built environment, TG3- Spatial dynamic modelling for Simulation of the interaction between the natural and the built environment, TG4- GIS in Education and Info sources. Objectives and work programme for each of these tasks are given and illustrated with examples, taken from state .of-the-art reports on the use of GIS elaborated by the participating countries/organisations. With the rapid development of IFC based standards for digital object oriented models of building products there is a huge need for property sets, such as environmental exposure data, reference service life, service life models, factor distributions, LCA and LCC data, which can be linked directly to the building elements. The significant drive within the AEC/IFC to provide for relevant location based data (GIS) via IFC format will be a major facilitator for access to relevant durability data on the specific building site. It is concluded that time is ripe for a broad implementation of GIS based applications in the building sector. Hence, it is recommended that the work programme of W106 for the coming working period includes a focus on support for an IFC based fully integrated design and planning process for the built environment, as well as a close link to the European based R&D frameworks for integrated life cycle management of the built environment.

Environmental Characterisation and Mapping with respect to Durability
- 2005
-
Ingår i: 10th International conference on durability of building materials and components.
-
Konferensbidrag (refereegranskat)abstract
- Service life planning calls for characterisation and classification of the exposure environment for the constructed asset(s) in question. Lack of knowledge of environmental exposure data and models among the building sector players is an important barrier for further progress towards service life prediction. The ever more evident climate change highlights even more the need for data and models on the exposure, when it comes to address its impact on the built environment. In general, requirements for establishing and implementing systems for quantitative characterisation and classification of durability of materials and components are: 1) well defined, and relatively simple damage functions for the materials in question, 2) availability of environmental exposure data/loads, including methods and models for assessing their geographical distribution, and 3) user friendly IT systems for storage, processing and modelling the environmental loads onto structures. Service life functions related to environmental degradation are today available for a range of building materials and components. As for availability of environmental data and models, as well as proper IT systems, it is shown that for most European countries, such data and models are available from meteorological offices and the environmental research area, and that these data and the work performed are directly applicable for service life planning and life cycle management of constructed assets. A short review of some of the most applicable models for environmental exposure and for degradation and damage of building materials and structures is included. The global climate system is likely to undergo changes, regardless of the implementation of abatement policies under the Kyoto Protocol or other regimes. Both the functionality of the existing built environment and the design of future buildings are likely to be altered by climate change impacts, and the expected implications of these new conditions are now investigated. The data and models are often directly exhibited in computer-based systems, often on GIS based platforms. With the rapid development of IFC based standards for digital object oriented models of building products there is a huge need for property sets, such as durability and service life data, linked directly to the building elements. The significant drive within the AEC/IFC community to provide for relevant location based data (GIS) via IFC format will be a major facilitator for access to site specific durability data, described by degradation models containing environmental (and other) degradation factors.

Konferensbidrag (refereegranskat)abstract
- In the building and construction sector all features are location based. The world of geographic information and application orientation is moving extremely fast, and there is a real danger that the slow uptake of new technology and applications in the building sector will again leave the sector trailing behind, also implying a loss in sustainable development and competitive edge. In order to deal with this issue CIB in 1996 established the task group CIB/TG20-GIS. Based on the report CIB 256 from this group and its recommendations, CIB in 2000 established the working commission CIB W106 "Geographical Information Systems", with the overall objectives to provide an international platform for R and D of GIS in the building sector. The W106 has members from 14 countries/organisations and will present its progress report at this Congress, while its final report with conclusions and recommendations is due for the 10DBMC conference in 2005. The work is divided into the following four Tasks: TG1 - GIS-requirements and availability of geographic standards-, data and infra-structures, TG2 - GIS-based analysis and modelling of flow and distribution of materials in the built environment, TG3 - Spatial dynamic modelling for simulation of the interaction between the natural and the built environment, TG4 - GIS in Education and Info sources.

Development and adaptation of a life cycle management system for constructed work
- 2005
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Lifetime Engineering (or Life Cycle Engineering) is a technical approach for meeting the current objective of sustainable development. The approach is aimed to turn today’s reactive and short-term design, management and maintenance planning towards an optimised and long-term technical approach. The life cycle based management and maintenance planning approach includes condition assessment, predictive modelling of performance changes, maintenance, repair and refurbishment planning and decisions. The Life Cycle Management System (LMS) is a predictive and generic life cycle based management system aimed to support all types of decision making and planning of optimal maintenance, repair and refurbishment activities of any constructed works. The system takes into account a number of aspects in sustainable and conscious development such as human requirements, life cycle economy, life cycle ecology and cultural requirements. The LMS is a system by which the complete system or parts thereof, works in co-operation or as a complement to existing business support systems. The system is module based where each module represents a subprocess within the maintenance management process. The scope of this thesis is focused on development and adaptation of the predictive characteristic of LMS towards a presumptive user. The objective is to develop and adapt a Service Life Performance Analysis module applicable for condition based Facility Management System in general and for condition based Bridge Management System in particular. Emphasis is placed on development and adaptation of a conditional probability based Service Life Performance Analysis model in which degradation models and Markov chains play a decisive role. The thesis deals also with development and adaptation of environmental exposure data recording and processing, with special emphasis on quantitative environmental classification in order to provide a simplified method of Service Life Performance Analysis.
