DESIGN MODELLING

Balance heating, cooling, lighting and thermal comfort, thereby saving electricity over the lifetime of the building and reducing mechanical equipment & maintenance cost.

A climate responsive approach is used during design, and the cost-benefit is evaluated with energy modelling. With rising electricity costs, making use of design modelling will also ensure the future-proofing of your building.

Climate Study

Obtaining the most representative climate data is a vital first step for building design and energy modelling alike. Using Meteonorm Software hourly weather data can be generated for a full year for any location in the world. Where required Meteonorm data can be calibrated for the best accuracy using measured data near the site. Graphing tools assist us to display the data intuitively, for easy interpretation and identification of suitable passive design measures.

Glazing and Shading Envelope Design

Find the balance between cooling, heating and lighting to produce an energy sustainable building by using three-dimensional energy modelling as part of the design. This results in a building façade that responds to the ever-changing outdoor conditions in the best possible way, while fitting into the project’s aesthetic constraints.

Natural Ventilation Design

Natural ventilation may provide sufficient cooling for energy-sustainable buildings in suitable climates. Energy modelling is used to determine the cooling potential and indoor-air temperatures for naturally ventilated buildings in accordance with ASHRAE standard 55. Three-dimensional air flow patterns can be evaluated by using advanced computational fluid dynamic (CFD) modelling.

Optimisation of HVAC Systems

We recommend combining advanced hourly energy modelling of HVAC components with trusted simplified sizing simulations. By coupling HVAC models directly to building geometry models both system control and load estimations are more accurate resulting in better design and operational savings. We work closely with HVAC teams to achieve the best results.

Thermal Comfort

A person’s sensation of warmth is influenced not only by indoor air temperature but also other physical parameters such as mean radiant temperature, relative air speed, and humidity. Thermal comfort parameters can be accurately assessed taking into consideration the indoor three-dimensional environment created in the energy model.

Material Envelope Design

Evaluate the effectiveness of thermal mass, light-weight construction and insulation. The scientific results from energy modelling will inform the building design, show the effectiveness of passive heating and cooling, the thermal responsiveness of light-weight buildings, and energy savings from a well-insulated façade.
