Wind Comfort

There is a distinct lack of building design literature specific to the Central Asian region. This perhaps, could be one of reasons for the only slight improvement of new building designs and construction. One does observe the highly glazed buildings are a particularly popular feature here in Astana, as like anywhere else in the world. However, excessively glazed surfaces combined with the weather extremes leads to adverse internal conditions and skyrocketing energy bills. The work presented in this paper is a part of continuing efforts to identify analyze and promote the design of ‘low energy, green and sustainable buildings with special reference to the Kazakhstan locality. In the present context, low energy buildings’ refers to buildings inherently low energy consuming by careful passive design, utilizing intelligent building technologies to automate building services and minimize wastage of energy and by incorporation of renewable technologies for its energy supply. Demonstration of improved environmental conditions and impact on energy savings will be outlined through a cause study incorporating application of passive design approach and detailed computational fluid dynamics (CFD) analysis for an existing building complex. The results indicated that there is a considerable influence of passive design and orientation on energy efficiency, wind comfort and safety.

Low Energy Buildings

Passivhaus or Passive House buildings are low-energy buildings in which the design is driven by quality and comfort, hence achieving acceptable levels of comfort through post-heating or post-cooling of fresh air. Additionally, Passivhaus building design follows the Passivhaus design criteria, as described in the Passive House Planning Package (PHPP). This article aims to introduce the Passivhaus background, development, and basic design principles. Finally, it also presents a brief description of the performance of Passivhaus buildings.
