Overheating and modernized buffer spaces: stationary modelling of typical block of flats

[摘要] In the light of inevitable future renewal solutions towards outdated Soviet urban housing, the study suggests a strategy of buffer spaces rebuilding, minimizing the impact of the retrofit on the inhabitants and allowing one to reduce indoor thermal discomfort at the expense of normalizing overheating frequency. Three, gradually becoming more complicated, possible retrofit approaches to the buffer spaces (balconies, the attics and basement) of an equivalent building are assessed graphically and via simulations in Passive House Planning Package. The modelling focuses upon two outermost south-eastern-faced apartments, that in their initial state experience temperatures, excessing 25°C - 26% of the annual occupied hours (while the temperatures excessing 25°C - should be less than 10% of the time - a Passive House criterion). The last and most developed approach is happened to be the most effective as it reduces the frequency to 4% in the modelled apartments.
