F.A.Q.
Please see the below frequently asked questions about our design services.
What are the benefits of using BSRIA Stage Design?
Benefits include improved project coordination, higher-quality designs, better risk management, smoother implementation, and meeting energy performance and sustainability goals.
Why is BSRIA Stage Design important?
It ensures a systematic, comprehensive approach to design, covering key stages such as concept, detailed design, construction, and handover, minimizing risks and improving project efficiency.
What are the stages of the BSRIA design process?
The BSRIA Stage Design process includes the following key stages:
Concept Design
Developed Design
Technical Design
Construction Support
Handover and Post-Occupancy Evaluation
How does BSRIA Stage Design impact energy efficiency?
The design process focuses on integrating energy-efficient solutions at each stage, optimizing building performance and reducing long-term energy consumption.
How long does it take to produce a BSRIA stage 3/4 design report?
A report timeframe will vary depending on the size and age of the building. A typical design project report will take 6 weeks to complete.
Can we take your design reports and commission another business to manufacture?
Yes you can take our reports and find another supplier.
The designs are bespoke and for your project only and can be used by other businesses to specify equipment.
However, CO2PEC offer a full turnkey solution with tried and tested, trusted brands and suppliers to save you time and effort researching the market, and can help you reach your decarbonisation goals faster.
What is IES Modeling?
IES Modeling is a software tool used for building performance simulation, which helps assess energy efficiency, thermal comfort, daylighting, and other environmental factors in building designs.
What does IES Modeling simulate?
IES Modeling can simulate various aspects of a building, including energy use, HVAC systems, lighting, natural ventilation, thermal comfort, and environmental impacts, to provide insights into overall performance.
How accurate is IES Modeling?
IES Modeling is highly accurate when used with correct input data. The accuracy depends on the quality of the building data, systems configurations, and environmental parameters provided in the model.
What types of projects benefit from IES Modeling?
IES Modeling is beneficial for both new build and retrofit projects, including commercial, residential, educational, and industrial buildings that aim to optimize energy use, comfort, and sustainability.
Can IES Modeling be used for both small and large projects?
Yes, IES Modeling can be used for projects of any size, from small-scale residential buildings to large commercial or industrial developments.
How long does it take to run an IES Model?
The time required depends on the complexity of the project and the level of detail in the model. Simpler models may take a few hours, while more complex simulations can take several days to complete.
