Sun is the renewable energy source whose usage exerts influence on architectural design. Facade concepts of energy efficient buildings are developed producing new facade structures and components. Photovoltaic systems, as elements of active solar systems are discussed in the paper and particular attention is paid to building integrated systems, as they influence building appearance. Classification and analyzes of PV systems - materials, supporting systems, coatings and design principles are presented in the paper. The purpose of this paper is discussion on design and construction possibilities for PV integration in envelopes of new and existing buildings. Possibilities for structural variability of envelopes with PV integrated systems are described in the paper. .
The article discusses the modern state of architecture and construction in the world, aimed on saving energy through specific architectural and structural design of buildings. It is noted that for the time being energy saving in the majority of countries is nearly the main problem, and that is a challenge for contemporary architecture and construction. There are some ways of efficient solution of the problem in question. Among these the design and construction of special types of buildings seems to be the most notable.
Energy-efficient buildings utilise the potential of renewable sources, among which heat pumps hold an important position. As this technology has a secondary effect on the environment through its noise immission, locations of outdoor units in the exterior should be subjected to the assessment. The present article deals with the options of placing heat pumps in the exterior and the placement assessment methods. The noise burden identification through the assessment of the time exposure is presented in the example of an in situ measurement.
