KEOTO was founded in 2009 as a spin-off from the Institute of Technology in Architecture of the Swiss Federal Institute of Technology Zurich, when the founders of the company decided to implement their research results in real projects. Since then, KEOTO collaborates closely with ETH Zurich developing cutting-edge software tools, which strengthen the competencies of our multidisciplinary team.
In 2012, KEOTO has signed a new research contract with ETH Zurich, focused on digital simulation and innovative visualization of façade systems.
KEOTO has developed and improved engineering software tools to address specific challenges in the field of Zero Emission Architecture + Engineering. With the use of his software tools, KEOTO has provided technically-feasible and cost-effective solutions for the specific challenges of its planning projects.
KEOTO’s planning and design process starts with the development of a digital building model, which allows for comprehensive analysis and evaluation at any phase of the project. Our planning process based on Building Information Modelling (BIM) enables us to optimize the total cost of each project, considering, on the one hand, future energy costs; and on the other, the upfront cost of the technical building system.
The software platform keoto.buildings – developed at KEOTO – was conceived to monitor the projects’ real-time performance in comparison to their planning objectives. In this sense, the planning objectives are based on the Building Information Model. The results provided by the BIM at an early planning phase are stored in keoto.buildings to be eventually compared with the building’s real-time performance. keoto.buildings can be of great value especially for large construction projects. In this case, real-time measurements can be compared not only with planning objectives, but also among different building sections within the same project. As a result, the data obtained can be used to control the steering parameters of the technical system, aiming at opimal energy use.
Keoto’s flagship product – the Design Performance Viewer (DPV) – is a modular software devoted to quickly estimate the energy needs and CO2 emissions of a building. The DPV is a reliable tool successfully used in construction projects; in addition, it is a subject of teaching assignments at the ETH Zurich and some other renowned universities.
The Design Performance Viewer can be used to promptly evaluate different building parameters along the design process. It has a set of predefined input parameters related to building use, which makes possible to directly calculate the building’s behavior with no need to introduce too-specific inputs. Relevant energy ratios are calculated in a few seconds and illustrative visualizations are shown. The impact of design and technical systems on energy demand and CO2 emissions are immediately displayed. By embedding the DPV into the planning environment, detailed information is preserved along the planning process and through the whole life cycle of the project. This leads to an efficient and lean planning process.
