Savings of up to 10.7% and, on

average, up to 5.9% in the

residential building's heating en-

ergy consumption. - These

outstanding results were

obtained by Kimmo Hilliaho in

his research on the balcony glaz-

ing's energy-economic effects

completed in August at the Tam-

pere University of Technology,

in Finland.

A new research confirms:

Balcony glazing saves energy

New, efficient windbox

The results show

that taking compen-

sation air from a

glazed balcony

clearly increases en-

ergy savings arisen

from glazing. In the

best case, the bal-

cony functions as an

efficient windbox,

which makes it pos-

sible for the balcony

-owner to reduce the

temperature by one

degree in the room

behind the balcony.

Thus the residents

can save energy and

improve their hous-

ing comfort.

The research was conducted in

Finland and supplemented with

reference calculations obtained

from Germany. The heating en-

ergy consumption of glazed and

unglazed balconies was compared

with each other by using field

measurements and computer

simulations. In addition, it was

ascertained how the balcony type,

thermal insulation and the direc-

tion affect temperatures inside

glazed balconies.

If installed for recessed

balconies, the glazing is

often a more efficient

energy-saver that the

glazing installed for

protruding balconies.

The savings for south-

side balconies are

slightly higher than

those for balconies fac-

ing towards other direc-

tions. However, the sav-

ings gained by both

types are substantial.

The study of glazing

tightness revealed that

larger gaps between bal-

cony glass sheets didn't

much affect energy sav-

ing levels.

Crucial is how the resi-

dents use their balcony

glasses. In most cases,

the Finns know the en-

ergy-economically best

way of using balcony

glazing: glasses are kept

closed in winter and

open in summer. How-

ever, the provision of

more accurate directions

is necessary to maxi-

mize savings.

New, efficient windbox continue.

Even higher savings obtained in Germany

balcony glazing varied

in Berlin from 5.6% to

12.0%. The glazing was

most beneficial to build-

ings with balconies fac-

ing towards south and

compensation air taken

through the balcony.

Taking supply air from

the balcony instead of

taking it directly from

outside was the factor

that had the most dis-

tinct impact on energy

savings.

On average, heating en-

ergy savings in Ger-

many amounted to

8.2%, which is even

more than in Finland.

"The research results can be utilized directly in many different ways," sums

up Kimmo Hilliaho. -"Balcony glazing allows property owners to postpone

facade renovations for several years, save heating energy and reduce operat-

ing costs.

The results provide grounds for architects to plan semi-warm space to be

used as green zones between the yard and interiors. It is also well-grounded

to include energy-saving glazing solutions in such renovation plans that aim

at reducing energy consumption.

For those who invest in balcony glazing, the information about energy sav-

ings and better structural conservation makes their procurement economi-

cally viable.
