Bioclimatic Toolkit

Tyréns is a unique company that carries on a tradition of long-term thinking and self-financed research and development.

We consider that environmental issues, particularly carbon reduction, are one of the major challenges of our time. This ideal permeates our whole business. We have concentrated our research and development effort in these areas and fund over £1.5million worth of research projects every year.

Climate resilient urban design has become a new paradigm. Outdoor spaces are more complex in terms of temporal and spatial variation and the range of activities undertaken.

One of the main aims of building design is to provide a comfortable place for living. Assessing thermal comfort has become an increasingly important tool in building and landscape design within urban environments.

The BioClimatic Toolkit uses a Computational Fluid Dynamic (CFD) airflow model that improves our understanding and predictive capability in:
Environmental diversity/outdoor thermal comfort
Influence of psychological and social-cultural parameters
Effect of experience and expectation
Socio-economic value of enhancing context
Economic effects of morphological design measures

Analysis allows the orientation of buildings and urban landscape to be refined and the design of hard and soft landscape elements that reduce the climatic impact of development on passers by and building users.

The model uses locally sourced climatic data to provide information on solar geometry, wind patterns and overshadowing. The outputs show comfort levels for users, using standard international UCI indices.

The solar mapping component assesses the potential solar energy availability within cities or neighbourhoods. Solar energy can be employed in a variety of locations and contexts including domestic roofs, commercial and industrial properties, and in brownfield and greenfield locations.

We have delivered solar mapping analysis in over a dozen cities or regions. The analysis can identify the likely level of solar recovery for each roof, allowing informed investment decisions to be made on solar technology at a district, neighbourhood or individual building level.
