Abstract
This paper aims to assess the environmental impact of family houses designed as a building with green technologies and green materials. These family houses are located in villages of Velky Folkmar and Jedlinka, which are situated in eastern Slovakia. The analysis investigates the role of application of these technologies on impact categories such as: global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), photochemical ozone creation potential (POCP), abiotic depletion potential fossil fuels (ADPF) expressed as CO2eq, SO2eq, PO43−eq, kg ethylene and MJ, respectively within “Cradle to Grave” boundary by using the LCA assessment method. The main contribution of the study is to highlight the significance of green technologies in reduction of environmental impacts. The presented results show that house with built-in green materials and technologies causes significantly lower environmental impacts compared to house where both green technologies and conventional materials are built. The operation phase (B6) is characterized by greater environmental impacts compared to the product and construction phases, as well as deconstruction phase due to the use of green materials and technologies.

Summary
Assessment (LCEA) and Life Cycle Carbon Emissions Assessment (LCCO2A) were reviewed in study [1]. Results show that they all share some similarities in the overall objective in evaluating the impacts over the life cycle of building construction. The major focus of evaluation of LCEA is on energy input, LCCO2A is on carbon-equivalent inputs and LCA is on both environmental inputs and outputs. All of these methods pointed to the same conclusion that the usephase of a building contributes the largest life cycle environmental impacts with their structural materials dominating the share. Study [2] investigates the potential environmental impacts related to the end-of-life phase of a residential building, identified
