Today, the building industry in Europe is characterised mainly by on-site production, which may be inefficient with regard to cost and production time. The sector is negatively associated with poor quality as well as an unsafe and unhealthy working environment. Facing the enormous need for reduced energy use and renovation of buildings from the post-war era, these problems are reasons why an industrial construction process for retrofitting is needed. Using well-designed, prefabricated elements, for example, can drastically reduce the production time, and thus possibly also cost of retrofit projects as well as minimise the social disturbance for tenants.
E2Rebuild is a collaboration project between 20 partners in eight European countries. Architect bureaus, construction- and housing companies as well as universities and research institutes participate in the project.
E2ReBuild aims to
- investigate, promote and demonstrate cost effective and advanced energy efficient retrofit strategies that create added value for existing apartment buildings and endorse end-users to stay and build a dynamic society
- to establish and demonstrate sustainable renovation solutions that will greatly reduce the energy use
- to create a holistic industrialised process that minimises technical and social disturbance for tenants and facilitates energy efficient operation and use of the buildings including encouraging energy efficient behaviour
This will be achieved by transferring technical innovations and advances from research to application and wide use. It will also change current inefficient way of doing business to a win-win situation for all involved actors.
PROJECT GOALS:E2ReBuild investigates, promotes, and demonstrates, cost-effective and advanced energy-efficient retrofit strategies that create added value for existing apartment buildings. The vision of E2ReBuild is to transform the retrofitting construction sector from the current craft and resource based construction towards an innovative, high-tech, energy efficient industrialised sector. We believe that industrial construction is part of the solution to both energy-efficient retrofitting and improved quality of life for people. An innovative, industrialised process can create living environments with good architectural values and buildings with very low energy use, at a low cost.
In E2Rebuild we adress these problems in order to speed up the development towards an energy efficient construction and building sector.
The aims of E2ReBuild are:
- To investigate, promote and demonstrate cost effective and advanced energy efficient retrofit strategies that create added value for existing apartment buildings and endorse end-users to stay and build a dynamic society
- To establish and demonstrate sustainable renovation solutions that will reduce the energy use to fulfil at least the national limit values for new buildings according to the applicable legislation based on the Energy Performance of Buildings Directives (for 2010) and to reduce the space heat use by about 75%.
- To create a holistic industrialised process that aims to minimise technical and social disturbance for tenants and facilitates energy efficient operation and use of the buildings including encouraging energy efficient behaviour.
Starting with the explanation of the condition of survey and planning as the intrinsic property of prefabricated solutions the text describes the requirements for knowledge based retrofit processes from survey, construction planning to production and assembly.
A fully featured 3D model for planning and production is needed otherwise industrialised retrofitting based on prefabrication is highly risky. The first crucial step in industrialised retrofit for energy efficiency is to translate built reality into the planning tools. The 3D model develops in different steps. It starts with the application of specific surveying methods to develop a 3D image from the existing object. Based on this data surveyors or trained architects or engineers have to develop the building information model. It is a transformation of real 3D data into usable planning data. The abstract gives an overview of current surveying methods and describes different approaches in building measurement based on Tacheometry, 3D Laser Scan and Photogrammetry.
Based on the demonstration project Grüntenstraße, Augsburg Germany the experience of the surveying and planning process is explained and gives an overview of features and guidelines of a comprehensive digital survey.
