Building Information Modelling (BIM)

Based on advanced BIM tools and deep understanding of the building physics which is essential to use the digital calculation tools. Energy demand arises from the interior space comfort requirements, which can be summarized as: i) visual comfort: 200-500 lx ; ii) thermal comfort: 20-25ºC at 40-60% relative humidity; iii) air quality index (AQI): between 0 and 50; 1.5-2 air; changes per hour, 350-500 ppm CO2 concentration; fine  particle 50 μg/m3 PM10 and 25 μg/m3 PM2.5 iv) acoustic comfort: 35-40 dB noise level. A usual method to estimate the building performance is to introduce model input and using thermodynamic algorithms to simulate the heat transfer in terms of conduction, convection (fluid mass transfer), radiation (UV,visual and IR) and latent loads. Perhaps the most sophisticated and exact algorithms are called Energy Plus, developed by US Department of Energy introduced in different graphical interfaces. Usual input required is: i) building geometry; ii) climate data; iii) site orientation and local shading; iv) building enclosure and HVAC data; v) user behavior and schedule of use; vi) automation control.

Smart home

The Smart Home service aims at building an integrated solution to provide smart home and wellbeing services based on a cross-domain data space, which will be further opened for other users as well. The main challenges are: interoperability of the technology solutions, secure and trustful data sharing, appropriate user-experience design of the mobile apps, etc. FI-Home will make possible life in a smart home to be: comfortable; healthy; safe; resource efficient; environment friendly; informed; exciting. The main functionalities of the FI-Home service will be: control over the house microclimate; monitoring thermodynamic energy balance; keeping track of energy expenditure of the house; seamless data and control compatibility among different equipment providers; variety of alerting and predicative algorithms to minimize power losses and negative environmental impact of the house.
