OUR LATEST PROJECTS

Energy Efficiency Design

Energy Efficiency is a mandatory part of the project documentation of any new object or reconstruction, renovation, major repair, remodeling, upgrade and extension of existing residential and non-residential buildings.

Our design team also offers this service to our investors and clients. With the Energy Efficiency calculations, we determine the necessary thermal insulation of the external enclosing structures of the building, the need to lay insulation on internal walls, floors and ceilings between heated and unheated rooms. We make details for every wall, floor and roof.
