In the context of the trend to increase energy efficiency of
buildings by thermal insulation, the demand for protecting
outside façades with functional façade paints could increase.
Façade paints products containing ENPs could for example be
an alternative solution for façade paints containing hazardous
biocides. Nanotechnologies also are expected to hold potential
for example for antibacterial or air-purifying inside paints
containing ENPs.
The NanoHOUSE project focuses on the most commonly used
ENPs in construction materials nano-Ag , nano-TiO 2 and nano-
SiO 2 comprised in large amounts in paints and coatings for
indoor and outdoor applications.
The scope of the project is circumscribed to the release of ENPs
during the post-production stages in the life cycle of both
indoor and outdoor paints and coatings for housing
3 What is NanoHouse
The goal of this project is to gather and to generate, when
missing, reliable scientific information and analysis, using
appropriate methodologies to understand the potential EHS
impacts of nanoproducts used in building (coatings and paints).
A life cycle approach prospectively gathers information about
the EHS aspects throughout all the life cycle stages of these
products and identifies the data gaps and drives the precise
needs of experimental work. Firstly, experimental work focuses
on the quantification of the actual sources of ENPs during the
use and ageing of indoor and outdoor coatings, during
renovation and demolition operations and during their final
disposal.
The main innovative aspects of the NanoHOUSE project are: (i)
to consider the whole product life cycle in regard to EHS and (ii)
to study the environmental behaviour and the toxicological
effects of the actually released ENPs (“aged” ENPs), and to
compare them with the pristine ENPs
As an important component of the environmental and
ecological system, NanoHOUSE aims at quantifying the uptake
of released ENPs by plants and determining the impact of ENPs
on those organisms.
NanoHOUSE aims at identifying and quantifying the effects on
human health along the pathways of exposure to human in
urban or residential environment. The major goal is to gain
insight into the influence of ENPs transformations (“aged” vs
pristine), routes of intake, duration of exposure on the
biokinetics throughout the entire organism (in vivo tests) and
the mechanisms of toxicity at the cellular level (in vitro tests)
and to develop a Physiologically Based PharmacoKinetic model
(PBPK) with a pulmonary dispersion model to integrate
different parts of human health effect measurement.
Finally, NanoHOUSE will improve end of life treatments
regarding ENPs release in the environment, and will participate
to the development of sustainable and competitive
nanoproducts by decreasing their potential to release ENPs.
NanoHOUSE project will thus contribute to the development of

appropriate solutions for the use of safe, sustainable and
competitive nanoproducts in housing through their whole life
cycle.
3.1 Summary of NanoHouse’s key strengths
The main outcomes of the project are:
• evaluate the risks associated with the use of ENPs in
materials for housing,
• improve the sustainability of ENPs containing paints and
coatings for housing and other applications by decreasing
their release-ability,
• propose a generic risk assessment methodology tested for
a selected group of nanoproducts that takes into account
the specificity of actually released ENPs,
• support the regulation concerning risk assessment by
contributing recommendations specific to nanoproducts
considering the whole life cycle of these products and
elaborating a first attempt of LCA,
• participate to the normalisation of release tests for
certification of nanoproducts in construction and other
applications,
• improve the current technical solutions for end of life
treatments of nanoproducts,
• propose a decision-making tool for sustainable and
competitive innovation and for nanorisk management
addressed to manufacturers,
• promote nanoproducts social acceptability.
4 Organisation of NanoHouse
The NanoHOUSE project is structured around five scientific
work packages (WP1-WP5) whose the previous aims and the
interdependency are described hereafter and in the Table 1.
