Solar construction is a practical way to design and build homes and other farm objects to live and work in both comfortably and economically, using techniques which reduce energy requirement for heating buildings, domestic water heating, lighting and operating appliances [Schwolsky and Williams, 1982, p. 266]. A variety of approaches enables builders to plan for different levels of energy efficiency in their buildings, and to apply a technique that is suitable for their own environment, climates, market and styles. Solar construction requires changes in a builder's approach to siting. Along with site there are concerns for access, views, drainage and compatibility to the landscape. Builders should consider slope and orientation, wind direction and velocities, vegetation, and the possibility of making use of solar radiation. Careful placement of all the constructions on their sites results also in reduced energy consumption and increased comfort. Farming is an economic activity involving the processing of natural foodstuffs and other products necessary for the requirements of our fast-growing human population. A failure to take the fragility of the environment into consideration in farming activities and methods can result in the deterioration of the physical, chemical and biological properties of the resources. One should deplore pollution of water and its excessive use, degradation of soil, pollution of air, reduced biodiversity, the homogenization of landscapes and the countryside [Ledwoń, 1998, p. 160]. Agriculture, in the past, played a vital role in the conservation of species-rich environments and habitats. Nowadays, certain types of farming do maintain this diversity. Intensive farming, on the other hand, has simplified ecosystems to such a degree that is now possible to describe the land it uses as a vast biological desert. Many habitats have been destroyed by the modernisation of farming techniques. Due to extreme energy consumption in agriculture and the use of heavy machinery, application of solar energy systems could eliminate or at least reduce great deal of the problems mentioned above [Ledwoń, 1999, p. 78].
