Zehnder America a Fresh Look at Indoor Air QualityZehnder America
Home should be a place where you can breathe easy, but today that might not be the case. Indoor air pollution can be worse than outdoor pollution, and people spend about 87% of their time indoors, an average of 69% at home.
Environmental Protection Agency studies found pollution indoors could be two to five times higher than outdoor levels, and in rare cases up to 100 times worse. In this special report sponsored by Zehnder America Inc., we’ll outline causes of indoor air pollution and discuss solutions available to create a safe and comfortable
indoor environment.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

3. Research shows that Europeans spend on
average 90% of their time indoors. We eat, live,
work and sleep indoor, and most of us do this
without thinking about how our indoor
environment might be affecting our wellbeing. An
unhealthy indoor climate can be the cause of
fatigue, headaches and allergies, and in the worst
cases it can lead to severe long-term illnesses
such as cancer and respiratory diseases.
Understanding and controlling our indoor air
quality can help reduce the risk of these health
conditions.

12. THE FOUNDATION IN ACTIVE HOUSE PRINCIPLES
The Active House Radar is a useful tool to
represent a holistic picture of a building based
on parameters that are a fusion of comfort,
energy impact and environmental load.
VELUX Group, Leapcraft and GXN Architects
worked on building a live version of the Active
House Radar for the Green Solutions House in
Bornholm in summer 2017.
You can read more about the project at
>> http://velux.com/gsh
We borrow the basic principles from the active
house approach to find ways to create key
indicators for a comfort economy.
13. Data from sensor based monitoring can be
used to analyse the long term and live effects
on indoor climate. Temperature, Humidity and
CO2 are relatively inexpensive to measure in
high frequency and in multiple locations.
In 2017 a project was carried out by Leapcraft
in collaboration with the Green Solution
House in Bornholm, Velux and GXN where the
indoor air quality has been continuously
measured and displayed live on
http://gsh.leapcraft.dk/.
Detailed findings of the project can be found
in Leapcraft’s report “Quantifying an Active
House”.
QUANTIFYING THE COMFORT LEVELS IN A BUILDING : SENSOR BASED MONITORING
14. QUANTIFYING THE COMFORT LEVELS IN A BUILDING : RESULTS
Overall, results tell us that the Green Solution
House building is performing reasonably well
with regards to the parameters measured
during the pilot period. Performance of the
building fit high standard compared to
building regulations.
In the examples on the right, we can see the
overall thermal comfort levels are quite well
managed across a few months indicating a
good basis for a comfort economy score.
Humidity levels are indicating a dry system
with high fluctuations. Generally, it can be
agreed that the building requires
humidification to bring it up to the category 1
building values. In most cases, the CO2 levels
are applicable to category 1 buildings. In some
cases the CO2 levels increase rapidly to above
800 PPM level relative to outdoor CO2
concentration, which in most cases can be
linked to high occupancy levels..
15. DAYLIGHT AS DRIVER FOR HEALTHY ENVIRONMENTS
The “Daylight and Well-being” booklet was
published as part of the Active House
Symposium held on September 2017 in
Green Solution House.
It explores how comfort in buildings can be
defined, integrated, monitored and improved
to the benefit of human well-being and
environmental sustainability.
16. DAYLIGHT AS DRIVER FOR HEALTHY ENVIRONMENTS
The two Active House radars visualise the
performance of the Green solution House,
before and after the renovation. The radar
clearly shows large improvements when
looking at sustainable performance.
Both Environmental and Energy criteria have
been significantly improved, but especially
Comfort shows an impressive Daylight level,
as well as ideal levels for Thermal
environment and Indoor air quality.
18. Adequate lighting and especially well-designed
daylight penetration provide an array of health
benefits to people in buildings. High levels of
daylight positively influence people’s mood and
well-being and helps to balance our 24-hour
circadian rhythm. If you get enough daylight, it
strengthens your ability to concentrate, you
sleep better, and you’re less likely to become
depressed.
Electric lighting during daytime should rarely be
necessary, which should make it possible to
reduce the overall energy consumption for
lighting.
KEY PARAMETERS QUANTIFIED IN THE COMFORT ECONOMY
Daylight
Exposure to high humidity levels is clinically
associated with respiratory disorders, allergies,
asthma and immunological reactions. Proper
ventilation controls humidity and prevents
condensation.
Well-designed, well-constructed, well-
maintained building envelopes are critical to the
prevention and control of excess moisture.
Suitable control of temperature and ventilation
should furthermore have a positive effect on a
buildings energy consumption.
Humidity
40%
Europeans are 40% more likely to have
asthma when they live in a damp or
mouldy home

1.5 times as many Europeans report poor
health when living in a dark home
19. The temperature in a room has a big effect on
how we perceive the indoor air quality.
However, temperature control can be a
challenge in old and poorly constructed
buildings, which often is related to a high
degree of wasted energy.
Apart from having an impact on our health and
comfort, a poorly heated room can also affect
our productivity. Spending longer periods of
time in a over or under heated ambience can
compromise our cognitive performance.
KEY PARAMETERS QUANTIFIED IN THE COMFORT ECONOMY
Temperature
Elevated levels of carbon dioxide are often
found in rooms with high occupancy and
metabolic activity such as meeting rooms,
bedrooms, open office areas and children’s
rooms. At high levels, carbon dioxide can result
in drowsiness, headaches and fatigue.
Elevated levels of carbon dioxide indicate that
an insufficient amount of fresh air is being
introduced in the room. If a room is not properly
ventilated the carbon dioxide level will rise
together with the concentration of other
unhealthy contaminants.
CO2
50%
Europeans who live in cold homes are
50% more likely to suffer from nose and
throat infections
48%
48% of Europeans who never air out their
homes also do not feel energized
20. Cooking, burning of candles and fireplaces all
contribute to a rise in the amount of particles
suspended in the air. Small particles (less than
10 micrometers in diameter) can penetrate
into the respiratory system and the
bloodstream, posing a great risk to our health.
Scientific studies have linked particle pollution
exposure to e.g. nonfatal heart attacks,
aggravated asthma and increased respiratory
symptoms. People with heart or lung diseases
and children are the most likely to be affected
by particle pollution exposure.
KEY PARAMETERS QUANTIFIED IN THE COMFORT ECONOMY
Particles
Volatile organic compounds are found in many
of our household products e.g. paints, furniture,
aerosol sprays and clothing. The extent and
nature of the health effects caused by VOCs
depend a wide variety of factors including
toxicity, level of exposure and length of time
exposed.
Health effects include: eye, nose and throat
irritation, headaches, fatigue and damage to
liver, kidney and central nervous system.
VOCs
21. Noise, can lead to a lot of long term issues
varying from cardio-vascular diseases to other
psychological effects according to the WHO. In
addition, poor acoustics can actually impede
communication and clarity of speech. A good
indoor climate has good enough acoustics to
not only enhance communication but also
reduce noise where it shouldn’t be. Creating an
ideal working environment requires good
implementation of sound barriers and
absorbers, separating noisy activities and
growing plants to reduce the distractions
caused by noise
KEY PARAMETERS QUANTIFIED IN THE COMFORT ECONOMY
Noise
A flow of fresh air is important in order to
achieve a healthy and comfortable indoor
environment. However, it is crucial that air
velocities are closely monitored as draught can
have a negative effect on the perceived indoor
climate.
When people experience draught, it is caused
by unpleasant air movements with too low
temperature where local body cooling occurs. It
occurs as a result of ventilation, open or leaky
windows, and when, for example, cold windows
produce temperature differences in the room.
The experience of draught can over time result
in different muscular disorders.
