ISOVER Multi-Comfort House Designer


The Multi Comfort Designer is based on a preliminary projection of the passive house from the ‘Passivhaus Institut’, Darmstadt. This involves a simplified version of the full-blown Passive House Planning Package (PHPP) and serves as preliminary draft material for subsequent construction of a passive house.


The draft is optimized by altering factors of varying influence such as compactness and orientation of the building, the quality of thermal insulation, quality and size of the windows etc. In many cases local climatic data can be useful.


The following factors can be entered, selected, modified and calculated:


  • General Project data like the project location, addresses, climate zone etc.
  • Geometry of the building draft
  • Energy efficient wall constructions to define the thermal quality of the building envelope
  • Quality of the glazing concerning thermal losses and solar gains
  • Thermal quality of the window frames
  • Awareness of thermal bridge free construction needs
  • Availability of a forced ventilation system and the effectiveness of the subsoil heat exchanger


ISOVER Multi-Comfort House Designer

All calculations and variations show at any stage of the planning:


  • The actual used wall constructions
  • The actual effective energy efficiency


ISOVER Multi-Comfort House Designer

The energy efficiency calculation results are:


  • The transmission losses
  • The ventilation losses
  • The sum of the heat losses
  • The solar gains
  • The internal gains
  • The sum of the heat gains
  • The resulting annual heat demand


All calculations can be stored and saved locally. A synopsis can be printed out at any planning stage.

The ISOVER Multi-Comfort House is a construction concept for new buildings and renovation which fits for residential and non-residential buildings and can be applied in all climatic zones. It allows great flexibility in building design and it is compatible with all types of constructions: massive or light-weight, onside or pre-fabricated. Furthermore it is achievable with reasonable costs and economically viable due to its very high energy savings and reduced need for maintenance. Over all Multi-Comfort House provides excellent comfort of living.


ISOVER Multi-Comfort House…


  • is designed to reduce energy demand for heating and cooling to a minimum
  • is based on the passive house concept, combining bioclimatic design and a high-performing building envelope
  • offers optimal thermal comfort and related energy savings
  • offers excellent acoustic and visual comfort
  • ensures permanently high indoor air quality
  • ensures fire protection and durability of the construction
  • is sustainable by taking into account environmental, economic and social factors over its complete life cycle.
