The façade or exterior envelope of a building is the element that makes the internal space habitable; it acts as a filter allowing in beneficial elements of the external climate whilst providing a barrier to the less desirable elements. Legislation and Regulations often set out minimum performance criteria that projects must achieve. This is now driven by the need to reduce carbon emissions and improve building energy efficiencies. GJA provides a very specific range of services from the early strategic design of a project right through to completion; the Façade Engineer being seen as “safe hands” regardless of a project’s size or complexity. Our engineers involvement on any project is both participative and proactive, in order to drive best value and excellence in design and delivery. These Façade Consultancy services recognise the need for a holistic approach from an engineering and performance perspective, the need for independent expertise to drive best value and the need to eradicate premature failure or deterioration of the most expensive element of the building construction. This demonstrates the clear need for specialised façade engineering expertise on major construction projects. Through the application of highly specialised skills, the Façade Engineering Consultants manage the various technological demands of the building envelope to meet the required design criteria. The services provided are a major contributor to the success of any project and are a significant quality differentiator.

The environmental performance of a building is a matter of balance between the energy use of building services and the losses and gains occurring through the building envelope. A holistic approach to the façade engineering and building services is essential for low energy sustainable buildings to create suitable habitable conditions.

GJA are able to carry out thermal analyses to EN and BS standards, U-Value calculations, condensation and risk assessments to assist the development process. Thermal analysis calculates the temperature and heat transfer within and between components in a design and its environment.

GJA are able to carry out thermal analyses to EN and BS standards, U-Value calculations, condensation and risk assessments to assist the development process. Thermal analysis calculates the temperature and heat transfer within and between components in a design and its environment. This involves the evaluation of the thermal performance of a framework and evaluation of partial or global U values of a building envelope.

Truly sustainable building facades can only be achieved by accurately establishing the levels of performance that these elements deliver in advance of the detail design and procurement phases. Environmental Compliance Analysis by Wintech allows for a deeper understanding of the likely levels of performance of a building envelope and can be used to accurately assess all of the thermal bridging and thermal bridging factors (Y value) of any potential design.

For the façade engineer, BIM modelling can allow for greater, more effective communication of details and quantities of a building between designers, architects and construction workers. The model is shared usually in a 3D digital form with significantly greater accuracy. The distribution of this information creates an ideal environment for those involved on a project to work together efficiently and effectively, with any changes being taken care of more immediately and cost effectively. A BIM model can also be used to perform analysis on important elements such as daylighting, thermal acoustical, structural and cost estimation at key points in the design and construction process.
