Halton Design Studio
Halton Design Studio: Testing and designing of the indoor environment
Comfort and life cycle performance targets are set at the pre-design and design phases. Halton supports the performance target setting and evaluates alternative indoor climate solutions. The system evaluations and indoor climate verifications are done in our world-class laboratory environment through full-scale tests and computer simulations.
Halton Design Studio OverviewConcept creation and co-design
Halton is involved from the concept and design phase to specify and customize the optimal solution in co-operation with your design team.
During the pre-design phase, the first step is to define the general requirements, and the technical and economic performance targets for the solution. Those may include indoor climate quality, comfort, usage and flexibility requirements, energy performance and life cycle costs. The targets are matched with the optimal indoor climate application and suitable components, including room systems, controls and zone management.
Computer simulations for simulating indoor environmental conditions
Halton's laboratories offer computational fluid dynamics (CFD) simulation services for indoor air applications. Computer-based flow simulations are used to optimise room conditions, especially when experiments are difficult to set up. Additionally, CFD simulation is often used to compare alternative solutions during the design or the pre-design phase.
CFD has been used to simulate several different cases ranging from detailed ventilation product simulations to whole-room airflow simulations. It enables a complete analysis of the indoor climate conditions, including a picture of the overall air distribution or local values.
Why choose the Halton CFD simulation service?
Halton CFD simulations may be validated by comparing them with laboratory measurements. Validation capabilities have also been used to develop realistic computational models of all indoor climate products; a feature that only a few service providers can guarantee. For simulations, Halton uses Ansys CFX, a commercial state-of-the-art CFD -tool.
Real-scale indoor environment testing
Indoor climate testing services are used to ensure that the indoor climate conditions are in accordance with the product design and features. Tailored tests and mock-ups are strongly recommended especially for special rooms and other demanding situations where the loads and the ventilation system differ from standard applications.
Tests are typically carried out for the following cases:
- Spaces with special loads and windows
- Designs for demanding acoustic environments
- Close proximity studies of displacement ventilation applications
Halton's test facilities allow test situations ranging from simplified tests to more detailed mock-ups. Multiple indoor environment parameters can be studied, including air temperatures, air velocities and acoustics, as well as product performance characterization.
Versatile test facilities are used to perform full-scale simulations in a variety of demanding environments, such as world-class concert halls, supermarkets, public buildings, offices and industrial premises.
Success story: Office development, Paris
In a major Paris office development project the aim was to develop an optimal cooling / heating / ventilation solution suitable for a building with unique architectural characteristics. In addition, the many open-plan office floors had higher than usual heat loads generated by a high number of computers and screens.
High heat loads combined with a unique architectural design demanded verification of the indoor environment design before the planning could proceed. Halton utilized computer simulations and full-scale indoor environment testing to find an optimal solution for the client.
Halton design software
Halton provides the advanced design tools, Halton HIT Design and Halton HELP, for product selection and performance simulation. Halton also supports CAD design with 2D and 3D product models.
Halton Tune
Halton Tune: Commissioning and validation
Halton products are typically installed by HVAC contractors, but for some systems we also offer commissioning services. Laboratory ventilation systems are a good example of Halton's turn-key solutions. Our validation services offer a tool for guaranteeing that the designed indoor climate conditions and user satisfaction are achieved in new or refurbished buildings.
Halton Tune OverviewDelivery, system commissioning and validation
Halton manufactures system components in accordance to ISO 9001 and ISO 14001 quality standards. Compliance with these standards ensures the use of only high-quality components and a low environmental impact throughout production. Halton chilled beams are also Eurovent certified.
Halton offers solutions for demanding spaces like hospitals and laboratories. With our commissioning and validation services, we guarantee that the designed indoor climate conditions, system performance and user satisfaction are achieved.
System performance validation
System performance validation guarantees proper functionality of the ventilation system before the occupants move in. By ensuring that all installations of components have been made correctly, and all parameters have been set according to the design, optimal thermal conditions and energy savings are achieved. Halton helps you provide a fully functional, comfortable, and safe indoor climate for the building users.
Validation of the indoor climate conditions in a construction project
Validation of designed thermal conditions in new or refurbished spaces reduces the risk of immediate complaints from users, reveals possible problem areas and makes it possible to make corrective actions in time. The indoor environment is created when the final use of spaces is determined, and end users have occupied and furnished the spaces. Typical changes made during the move-in are relocation of partition walls, furniture lay-out changes, and changes in the positioning of meeting rooms and office areas. At that time, the final adjustment of technical room systems should be done.
Validation of the indoor climate conditions starts with an evaluation of the indoor climate carried out already at the planning stage. When the building is finished, the validation continues with an occupant satisfaction survey. Based on the gathered feedback, a perception map is collected to identify and locate the problem sources in various parts of the building, and in different areas of the indoor environment. A technical analysis on site helps find the sources of potential problems. This information may be used to fix problems related to building engineering systems before the warranty period ends. If a problem is caused by the use of the premises, the results help clarify the situation for the users. Validation of the indoor climate is intended for project developers and real estate owners, who want to ensure good results for their projects when it comes to perceived high-quality indoor environment.
