Abstract

Solar thermal installations are one of the popular types of renewable energy sources. This paper presents the comparison of the considered design variants of the typical solar hot water installation on the basis of Life Cycle Assessment. The simulations and the design criteria included:- optimal angle of inclination and orientation of collectors for the selected location (simulations in GetSolar),- optimal type of collectors (simulations in SimaPro).Life cycle analysis of solar hot water systems shows that this technology has the potential to reduce the environmental impact of hot water preparation while compared to the conventional energy sources. However, the optimisation criteria used for green designing in the life cycle perspective can significantly improve the environmental balance of the analysed technologies.

Highlights

In the recent years, the concept of sustainability has become the common interest of various disciplines
Green designing is focused on actions aimed at environmental improvement of products during the initial phase of its life, based on selection of materials or products with lower environmental impact, application of alternative processes, improvement in logistics and building processes, etc. [3]
One of the major rules in green designing of buildings is the use of alternate power sources such as solar or wind power [1]

Summary

Introduction

The concept of sustainability has become the common interest of various disciplines. The explanation for this popularity is the need to perform the sustainable development in our economy, society and environment. Sustainable development in the area of buildings means constructing structures and using systems that are environmentally responsible and resource-efficient through the various stages of a building life-cycle [2,3]. One of the major rules in green designing of buildings is the use of alternate power sources such as solar or wind power [1]. Solar thermal installations designed as a source of hot water can be performed with the use of several types of collectors, installation materials and locations
