Passivhaus Energy Modelling

Passivhaus is in practice the world's highest performing building standard. Production of a comprehensive thermal analysis using the Passivhaus Planning Package (PHPP) will ensure that the proposed design and fabric specification is properly considered and the resulting performance specification can be trusted. Ecospheric creates an energy model as a first step with every building project, at any scale, to establish a solid foundation for all future decisions. It accurately predicts the energy use and can help inform design.

A PHPP model offers whole building heating demand information and facilitates the process of Passivhaus or AECB certification. The energy model provides the fundamental basis for the following:

- all fabric and building services specifications

- energy generation sizing

- total system efficiencies for energy and carbon optimisation purposes

- user profiling for occupancy based optimisation and comfort
