Short description of the pilot project
The municipality of Polcenigo wanted to build a new wing of the school, which had the characteristics of earthquake resistance, energy conservation, rainwater harvesting…
The building was to approach the type “to nearly zero energy building.
Process and planning quality
The school was built with an integrated contract: the town council has approved the preliminary project and made the race for the execution of the work, including the definitive and executive project. This allowed them to reduce significantly the time required for execution, and to choose the best project.
Implementation of service package
Module 5A: Monitoring on energy consumption, support for maintenance, plan and user manual of the building
Energy and Utilities
A main attention has been paid to the design for the purpose of reducing energy consumption. In this regard, the project provides a prefabricated wooden structure consisting of vertical and horizontal perimeter with natural materials, such as rigid panels (OSB, DWD), which consist mainly derived from the processing of wood and insulating bio-soluble mineral wool, with high density -Energy Class A.
In perimeter walls it is also provided an insulation “overcoat” that allows the reduction of thermal bridges and the exploitation of the thermal inertia of the wall.
In order to avoid waste in terms of energy the design has also tried to limit the heat losses in winter through the exterior: the use of two glass plates separated by a cavity filled with Argon gas and with low emissivity coating allows rag-reach very high values of thermal insulation.
d) Renewable energy
There is a solar thermal plant for the production of hot water with a net absorber surface of eight square meters positioned on the pitch of the roof facing south.
