Approach to sustainability
We help clients use (Historic) BIM to make their restoration, transformation or new construction as sustainable as possible. Through our experience and intensive cooperation with specialists, we want to make a significant contribution to making the built environment circular, climate adaptive and energy neutral.
Our goal
Accelerate energy transition by designing energy-neutral buildings with circular materials in a climate-adaptive environment.
Reason
By 2050, existing built environment: energy neutral, circular and climate adaptive.
Step 1
SO analysis
As an example; Making existing real estate more sustainable; Rijksmonument Herenmarkt 10-12 Amsterdam commissioned by Municipality of Amsterdam, Municipal Real Estate.
The first step in the process;
Working with a structural engineer, cost expert and a consulting firm in sustainability, we create an SO analysis appropriate for a specific location. The goal is energy label A / A+, depending on the condition and use of the building. Any modifications and/or extensions will be sketched and calculated by the cost expert.
Step 2
Scan point cloud
The second action is to scan the existing property. We can do this very accurately with a “VLX Mobile wearable mapping system. This is a mobile scanning device that can scan the building in about half a day. Then the data are processed in a program and prepared in a “point-cloud. We can import the point cloud into our modeling programs, in this case Archicad 26.
Step 3
BIM model (building information modeling).
We create a BIM model of the entire building.
After the created scan is imported as a point-cloud into Archicad 26, we are going to model the existing situation exactly. Depending on the complexity of the structure, this will take about four weeks.
Step 4
ILS schedules (Information Delivery Specification).
In addition to modeling the plan, we add ILS qualifications of the materials and elements used. By doing this, we have a good overview of the qualities of spaces and specific elements among them at a later stage (‘phase control sustainability measures by energy evaluation / ECO designer Star’).
We can input important properties such as thermal resistance, air density, specific gravity, thermal conductivity, etc. for each specific element.
Step 5
ECO designer star + design LCA
By linking software applications such as “ECO star,” “energy evaluation,” and “Bridge simulation” to the model, the energy performance of the design can be determined and adjusted if necessary.
At a later stage, we may link VABI software, software for calculating building energy performance according to the NTA-8800, to the model. After realization, the level of the energy label can then be precisely checked.
Step 6
Tender / Implementation
The final design provided with specifications and descriptions are going to be used to select an appropriate contractor(s). The BIM model will be used by all parties (contractor and subcontractors) for engineering of facilities and structures.
The BIM model (IFC) becomes the property of the client. He can always access the model through a viewer, which can be e.g. Being a BIM keeper. At a later stage, MJOPs and maintenance software such as Planon and Madaster can also be linked to the model by the client.
