Rapid energy analysis of buildings
Simplified but still accurate energy analysis of buildings
Drastically reduce time requirements
Deliver advanced energy analyses in only a few hours instead of multiple minutes
Ability to compare different
energy solutions
Identifying the best options to boost the energy efficiency of your building
Accurate estimation of the design power of the heating and cooling plants
Perfect for presizing HVAC systems based on the needs of your building
For Architects
Evaluate different design options during early stage design to identify the best ones in term of energy needs, thermal comfort and sustainability.
For Engineers
Perform fast and simple simulations to obtain details on energy and power needs of the building, evaluate design changes and pre-design of building systems, with minimum impact on the design process.
For Building Managers
FREDS has more than 10 pre-set building categories:
review your building, check its performance and understand the potential impact of changes and refurbishments, with a simple set of required details.

Detailed evaluation of energy needs and temperatures on a sub-hourly basis in operative conditions

Thanks to the use of advanced dynamic simulation models

In depth evaluation of power requirements for heating and cooling plants

For a correct sizing of plants and pre-sizing performances during operation

Developed through years of research from our team of academic experts

Through the use of advanced models and the development of robust information databases

Online software that provide rapid, accurate evaluation of the daily energy performance of a built environment

FREDS 4 Buildings calculates dynamic energy needs of a construction project based on geographic location, climate, use, geometry and the materials. This information is converted into a powerful computational model which  gives users unparalleled insight into how proposed buildings will perform year round when constructed.
