Abstract The relevance of the construction of ecological houses (eco-houses), i.e. houses made from environmentally friendly building materials, is increasing due to the exacerbation of environmental problems on a global, regional and local scale. The purpose of this study is considered to be the actualization of the concept of ecological houses in relation to modern conditions, taking into account new and future requirements for buildings. Ecological houses are considered as a kind of modern green buildings. Particular attention is paid to energy efficiency as an essential requirement for new buildings. Eco-friendly building materials have two qualities at the same time: they are more favorable to humans; their use has a minimal impact on the environment, taking into account the entire life cycle of the building material. As a rule, natural materials (materials of natural origin) are considered environmentally friendly. It is rationally to apply the experience of energy efficient and green construction for environmentally friendly buildings: compact architectural forms, translucent structures with the effect of passive solar heating, supply and exhaust ventilation with heat recovery, automation of engineering systems, elimination of heat bridges (cold bridges).

AbstractThe paper presents results of a research for determination of a few general thermal-physical properties of environmentally friendly building materials made by clay, sand and straw. The aim of this study is to establish their heat insulating and energy-efficient capacity. All specific measurements were carried out by using the newest generation thermal conductivity analyser Mathis TCi.The results showed that the studied composite materials are good thermal insulators with thermal conductivity less than 0.5 W/m.K, which depends on the straw amount. Even less than 0.5 wt.% straw reflects on the insulating properties by decreasing the thermal conductivity coefficient with nearly 50 %.

The addition of a photocatalyst to ordinary building materials such as concrete creates environmentally friendly materials by which air pollution or pollution of the surface can be diminished. The use of LiNbO3photocatalyst in concrete material would be more beneficial since it can produce artificial photosynthesis in concrete. In these research photoassisted solid-gas phases reduction of carbon dioxide (artificial photosynthesis) was performed using a photocatalyst, LiNbO3, coated on concrete surface under illumination of UV-visible or sunlight and showed that LiNbO3achieved high conversion of CO2into products despite the low levels of band-gap light available. The high reaction efficiency of LiNbO3is explained by its strong remnant polarization (70 µC/cm2), allowing a longer lifetime of photoinduced carriers as well as an alternative reaction pathway. Due to the ease of usage and good photocatalytic efficiency, the research work done showed its potential application in pollution prevention.

Techniques for reducing power consumption in digital circuits that underly automatic control of modern engineering systems are of paramount importance due to the simultaneously growing demands for portable multimedia devices and energy conservation. Digital filters, being ubiquitous in such devices, are thus a prime candidate for low power design. We review an algorithmic approach to low power frequency-selective digital filtering, an essential ingredient for energy efficient technological innovation in many domains.
