Building Lifecycle Research Group

The Building Lifecycle Research Group approaches the building lifecycle as a whole, integrating the construction process and its outcomes with management strategies, technologies, building materials, economics and facilities management. Recent research has included:

  • Multi-attribute decision making methods for the assessment of different management strategies;
  • Developing and providing BIM-related know-how;
  • Different aspects of construction economics and management in the major fields of civil engineering;
  • Surveys on the building life cycle and technical conditions of housing;
  • Disaster resilience of built environment;
  • Educational aspects of civil engineering, etc.
  • Regulation of construction activities and creation of normative materials and standards for the Estonian construction industry;
  • Utilization of oil shale ash in the production of building materials;
  • Utilization of oil shale mining waste materials in concrete;
  • Energy saving and the renovation of buildings.

 The Research and Testing Laboratory of Building Materials has certified testing personnel, standards, methods and equipment for the evaluation of conformity for various building products: cement, mortar, grout and concrete products and products from natural and artefact stones and insulation materials. Research involves the following studies:

  • Main characteristics of binders or binder constituents based on oil shale ashes from electrostatic precipitator systems;
  • Basics of new utilization processes for oil shale combustion solid wastes;
  • Low strength backfilling concrete based on the residues of oil shale processing;
  • Frost resistance of various concretes and comparison of their test methods;
  • Building properties of chemically treated timber;
  • Durability characteristics (vapour and water migration) of facade systems, thermal insulation and external facade coverings.

Ongoing Projects

REGARD: REbuildinG AfteR Displacement

Disaster events such as earthquakes, windstorms, landslides, floods, tsunami and conflicts are among well-known causes that generate and aggravate displacements. Aim of the project is to develop competencies (or bridging knowledge gaps) in rebuilding communities following disaster and conflict induced mass displacements from the perspective of the built environment .

BECK: Integrating education with consumer behaviour relevant to energy efficiency and climate change at the Universities of Russia, Sri Lanka and Bangladesh

The objective of this project is to upgrade the curricula with new harmonized study modules on consumer behaviour related to energy efficiency and climate change at the universities of Russia, Sri Lanka and Bangladesh. This aims to increase their capacity to modernise continuously the quality and relevance of education according to the global labour market needs and to ensure international cooperation. The goals are: - to transfer European practices in education (learning and teaching tools, methodologies and pedagogical approaches including learning outcomes and ICT-based practices) from participating EU universities to universities of Russia, Sri Lanka and Bangladesh; - to assist competence development of teachers within the universities; - to develop the Simulated Big Data Interuniversity Networked Affective Educational Centre to encourage use of ICT-based methodologies in education and research.

Digital Model of Building Lifecycle

Aim of the project is to develop tge digital building lifecycle information model for construction activities in Tallinn. These simulation models will enable to make optimal decisions for different stages of building lifecycle as design, construction, maintenance etc.

Principal investigator: Prof. Irene Lill

Developing an unified construction classification system

The aim of the work is to create a unified classification system for construction, which takes into account modern trends in BIM technology and digital engineering, and creates a coherent and understandable language for managing building information. A common classification system must cover the entire life of the building, from the initial task and ending with environmentally conscious demolition. The common classification system must be applicable to buildings as well as to infrastructure facilities. The developed classification system must allow creation of a common and intelligible digital information space for all participants in the building's life. The system must ensure a clear, transparent and rational structure, which, as a result of it, enables the implementation of BIM technology and its work organization, facilitates information exchange, information processing and the organization of activities, that is building communications.

Influence of CFB ash to long-term properties of concrete

Aim of the research is to assess the possible influence of CFB ash (ash as cement constituent) to long-term properties of concrete made using CFB ash

Principal Investigator: Researcher Tiina Hain


The BRITAE project is aimed at development of joint curricula modules on building resilience in tropical agroecosystem in Sri Lankan universities in order to enhance the quality and relevance of education of students to the global market needs and to ensure international cooperation in line with the above needs. The objectives are to develop a joint MSc curriculum on tropical agroecosystem based resilience and climate change impacts, create a Smart Resilience Center for teaching, learning, research, and development, implement an online student service platform by blending European practices in education and increase international cooperation on research programs that tackle ways to increase societal resilience to disasters and reinforce international educational and scientific networking.

BIM-enabled Learning Environment for Digital Construction

Digitalization is driving changes in the real estate and construction sector. A central feature of this digital transformation is Building Information Modelling (BIM) which refers to the integrated digital representation of all building-related information. The BIM-enabled Learning Environment for Digital Construction (BENEDICT) project aims to leverage the possibilities of BIM to enhance the education of real estate and construction professionals. The project will develop an open, online BIM-enabled Learning Environment, initial learning resources and demonstration course materials to facilitate realistic, immersive and integrated learning experiences.

Cluster of digital construction

Project leader: prof Roode Liias

Development of information technology has greatly influenced also the development of construction sector and has created the possibilities for increasing efficiency there. The goal of the cluster is to rethink construction and the business model there. The goal of the cluster is to increase the added value of the sector through using It solutions. The outcome should be the environment which is based on the cooperation of the partners and construction itself is based on the lifecycle concept of the buildings.
