“…The same authors also affirm that one of the properties of balconies is to improve the uniformity of air almost without exception higher than outdoor air temperature [3,6,7]. Hilliaho et al [8] obtained a mean temperature of 2.0 °C and 5.0 °C higher than outdoor temperature in the field measurements carried out on balconies in Finland without and with retractable glass panels of their openings, respectively. In general, the studies show that these highly glazed spaces perform well compared to the environmental comfort of buildings located in regions of high latitudes [9], probably because they function as a strategy for gaining heat.…”

The balcony is responsible to a series of effects on the environmental behavior of a building, mainly in relation of thermal comfort and air distribution to their indoor spaces. Currently a very common practice in several metropolitan areas is the closing with retractable glass panels in balcony openings. This work analyzed the effects of glazed balconies upon thermal comfort in a hot tropical region. Environmental parameters were carried out in a flat alternating the conditions of retractable glass panels to balconies. Thermal simulations were performed considering closing or not the glass door that divides the balcony room; the building material used on the balcony sill; and the use of curtains or shading devices. The results show the maximum mean hourly temperatures recorded on the balcony during the period when the retractable glass panels were closed, reaching peaks between 31.7 and 39.2 °C, above the comfort range recommended by ASHRAE 55. All situations simulated show the thermal discomfort prevails in the use of the closed glass panels reaching DhTD of 94.55 °C/day. Thus, this practice of using most of the closed retractable glass panels in the balconies presents disadvantages and inefficiencies especially in hot and humid tropical climate regions.

“…In a paper by K. Hilaho, 'Effects of Added Glazing on Balcony Indoor Temperatures -Field Measurements', Hilliaho et al observed a lack of awareness in the way residents in Finland operated the glazing in balcony enclosures, sometimes keeping glazing open in winter, and closed in summer. This not only reduces the potential for energy savings through solar gains in the heating season, but also requires additional energy to make up for the increased cooling demand during warm months (Hilliaho, Köliö, Pakkala, Lahdensivu, & Vinha, 2016).…”

“…Hilliaho et al found that the less airtight an enclosure was, the colder the temperature that was measured inside. In addition, it was found that the degree of airtightness was directly proportional to the amount of glazing that was used, and as a result, glazing on two sides of a balcony was preferred, as it encouraged more solar gains than one side of glazing, but displayed a higher level of airtightness than three sides of glazing, keeping temperatures in the enclosure higher (Hilliaho, Köliö, Pakkala, Lahdensivu, & Vinha, 2016). The study by Hilliaho et al did not touch on the relationship between airtightness and moisture accumulation within the enclosure.…”

The Effect of Balcony Enclosure Retrofits on the Performance of MURBs

The City of Toronto has been undertaking retrofit projects to refurbish an aging building stock and increase performance in multi-unit residential buildings (MURBs). These retrofit considerations include solutions proposed for balconies, a common weak point in the building structure. A balcony enclosure retrofit was one such solution, using overcladding to insulate the exposed balcony slab and parapet, enclosing the open portion of the balcony with glazing. The effect of the balcony enclosure differed depending on the balcony type, varying with characteristics such as balcony to façade ratio, orientation and the projection type of the balcony, whether inset or projecting. When models were retrofit with balcony enclosures, results showed an overall decrease in energy use as the enclosures raised internal air temperatures, lowering demand for heating. The balcony characteristics which showed the largest decrease in energy use when retrofit with balcony enclosures were inset balconies with high balcony to façade ratio.

Reducing Annual Heating Energy Consumption of A Building By The Sunspace Application

In recent years, renewable energy sources and correspondingly the use of passive solar energy systems in buildings have gained importance. This study focuses on the reduction of the annual heating energy consumption of a building located in Istanbul by the application of sunspace as a passive solar heating system. At the beginning of the study, the heating and cooling energy consumptions of the reference building was determined. In the next step, the effects of the sunspace that designed on the southern facade of the reference building, to the heating and cooling energy consumptions were analyzed on a monthly basis by the IES program. The glass surfaces of the designed sunspace consist of double glazing filled with argon, which can provide heat control. The area in which the sunspace and the heated environment are adjacent is also made of the same type of glass. After the application of the sunspace designed with these conditions, the annual heating energy consumption of the building has been reduced from 4,6708 MWh to 3,0876 MWh and a saving of 33,8% has been achieved. Although sunspace can save considerable amount of heating energy consumption on cold winter days, overheating problem occurs in summer period. In order to prevent this problem and also prevent solar radiation enter to the sunspace, the curtains were used as a shading element on the roof of sunspace. With this application, the extra cooling energy consumption was reduced, but still was very high compared to the first case. At the final step, the same shading element was applied to all glazed surfaces of the sunspace and the increase in cooling energy consumption was largely eliminated.
