Sustainable building certification – Renovation or demolition? – Charlotte Schou

Project name: Sustainable building certification:  Inspiration, definition and documentation for a decision process between renovation versus demolition.

Project student: Charlotte Schou

Project status: March – August 2013

Publication: Specialerapport_FINAL

Course type: Master project

Supervisor: (Al)Fred Heller, DTU Civil Engineering & Peter Weitzmann, Cowi

Summary: The aim of the project is to define a method for deciding between renovation or demolishing of existing buildings. To have a well-defined set of criteria to build the decision on, sustainability certification schema are applied and supplied with characteristics of renovation that is not included in the certification schema. The method will be applied on real world case. The goal is to develop an method that visualized the many different aspects of the decision topology for a building owner to decide on. Hence communication of a wide range of different data will be one objective.

Vision talk: Decision support based on visualization of complex data, the application of advanced modelling and simulation tools to generate necessary information for the decision process and application of open standards are aspects from the overall vision that are addressed in this work.

Next step: The tool must be generalized and probably transformed into a web-application or even a mobile app. (Have you got the skills, than let’s hear from you).

3D BIM for a comprehensive design proces – Theis Andersson

Project name: 3D BIM models – a more comprehensive design proces

Project student: Theis Andersen

Course type: Special project, Autumn 2012

Supervisor: (Al)Fred Heller

Summary: The vision is to develop a web configuration tool through which customers are able to configure the building they want to buy. To be able to do so, the information describing the buildings, the products, characteristics and configuration options must be represented. This is done partly in a Building Information Model (BIM) in 3D CAD model within the tool Revit. The project defines a prototype building in Revit, informs the details in the BIM part and utilizes a set of components and computer programs to compute relevant information on e.g. price, scheduling, energy demand, indoor climate modelling and much more. For this purpose, the following components are applied:

  • Rockwool Energy Design (for the Danish building code computations) – alternatively Be10 can be used.
  • Sigma (for price calculations)
  • Navisworks (for planing)
  • Ecotect (for energy and indoor environment, daylight computations)

Most integration between the components has been possible, but the integration with Be10 did not work within newest versions, hence Rockwool Energy Design was applied instead.

Vision talk: Decision making towards a sustainable future demands interoperability between tools that generate and collect information on the decisions to be made. For building design, design tools must be supported dynamically by technical software from many different technical domains. It is not probable that there will be a single tool, handling all the computations. Hence a platform model is preferable.

Next step: The current project is a small step in a long process. There is a need for interoperability, getting the tools to work together in a automated way. The BIM data models are to be expanded, pricing more realistic and much more.  The whole integration with the web interface for configuration is not yet taken up. A simple way of doing so could be to dump the intermediate results and information in a file-tree to be utilized from a web solution.

User friendly visualization of urban and building specific data – Lærke Philipsen & Mads Harding Møller

Project name: User friendly visualization of urban and building specific data

Project student: Lærke Philipsen & Mads Harding Møller

Publication: Brugervenlig visualisering af byplans- og bygningsspecifik data (Danish, educational)

Course type: Special project, Autumn 2012

Supervisor: (Al)Fred Heller

Summary: The idea of the project is basically to visualize complex data for decision making. Similar to the Google Map idea, you visualize e.g. energy data at any level of zoom. You can show data on maps (GIS) in 2D, zooming in still visualizing in 2D. When zooming even further, you will see the streets visualized in 3D with data represented on the relevant surfaces (e.g. solar energy potentials, potential for green roofs and much more). When zooming even further, you enter the building and get very detailed data visualization on surfaces but also on the plan sketch of the buildings.

The report gives a lot of pointers to ideas for visualizations. The result is a proof of concept in paper form (see report above).

Vision talk: Visualization is very important for supporting decision making. If we are to decide the changes that are demanded to reach a sustainable future, the decision making process involves very complex data that is easier to be understood, when communicated visually. Hence this project gives a first idea of what can be done.

Next step: To implement the solution in a digital prototype.

Copenhagen did it! See the report on the implementation by 3D bymodeller til screening for potentialet for solceller og grønne tage and look at it yourself at http://kbhkort.kk.dk .

Google did it! See the Google Indoor “Maps” solution that has different names “Plan” “Indoor maps” … https://www.google.com/maps/about/partners/indoormaps/.

The interest for further implementations of the ideas is broad. We are looking for students to follow up including BIM, GIS and other technologies, visualizations and app implementations.
