of the building, the faster the wind and the colder the atmospheric temperature becomes. Therefore, in
some buildings the width of the glass has been double, but in any case a double window arrangement
(i.e. placement of two conventional single‐glazing widows in the same opening) has been used. Due to
the climatic conditions of the city, buildings do not require the use of air conditioning or heating,
therefore, sometimes, especially at night in winter, the temperature of the rooms can become cold, being
below the line of comfort. Also, the residents of mid‐ and high‐rise buildings tend to experience the
loud noise associated with the airflow through the loose windows as well as the coldness due to the
undesirable ventilation heat loss.
The purpose of this research is to measure the impact on the thermal comfort of several glass
arrangements in window installations, both in traditional architecture and in contemporary buildings,
in order to propose adequate sustainable practices in construction.
2. Materials and Methods
In order to better understand the characteristics of glazing in different types of Arequipan
architecture, this study, two different types of buildings were compared: a traditional, colonial mansion
named “Casa del Moral” and a modern building named “Los Manzanos Housing Building”. Both
buildings are located in neighboring districts of the city and separated 1.6 Km. from each other. The
rooms where the measurements took place in both buildings had the same orientation. Measurements
of temperature, thermal stress and noise were taken using specialized equipment at three times of the
day, early morning around 6 A.M., early afternoon around 2 P.M. and late evening around 11 P.M. Also,
three different types of windows were used in the experiment: single glazed, tempered and double
glazed windows.
2.1 The Selected Buildings
2.1.1. Casa del Moral
Located at 16°23ʹ48.74ʺS 71°32ʹ16.23ʺW, at an altitude of 2346 meters. It got its name for the
blackberry tree (moral, in Spanish) that grows in its main courtyard. It is one of the most notable
mansions of the civil colonial architecture of Arequipa built in the 18th century, arranged around a
courtyard and its long facade is decorated with mestizo elements carved in ignimbrite stone. As many
other constructions of its time, it is a single story building made of volcanic stone, arranged around a
central courtyard. Its thick walls supported vaults and had to endure the effects of continuous seismic
activity (Fig.1).
