Talk Title
Efficient interactions between low embodied building materials, architectonic choices and CO2 emissions
Talk Abstract

The existence of buildings as such, involves a significant use of energy and natural resources, and as a consequence, a negative effect of the entire building sector on the natural environment (European Commission, b.r.; Bayer, Gamble, Gentry, et al., 2010; Antink, Garrigan, Bonetti, et al., 2014). The consumption of energy occurs primarily during the building’s use - energy is used for heating, preparing domestic hot water, as well as powering the appliances and lighting inside the building.

Commonly applied measures of improving the energy efficiency of buildings focus on, before everything else, the use of effective thermal insulation in exterior partitions (most often by increasing the thickness of the insulation), using windows with better parameters, or additional appliances (e.g. mechanical ventilation with heat recovery). These measures are usually linked with an increase in embodied energy and a higher use of resources, as well as, increased greenhouse gas and other harmful substances emissions (Bayer, Gamble, Gentry, et al., 2010).

Designing a low-energy and ecological building requires performing simulations and analyses, which include the building’s entire life cycle (that is from resources acquisition, transport, production and assembly of materials, use, renovation, and demolition). One of the methods of evaluating the effect of products and processes on the environment over the course of the entire existence cycle is Life Cycle Assessment (LCA). 

The topic of this paper will concentrate on  the procedures and analysis allowing development of a simple method for the ecological analysis of small buildings. The information collected was used to calculate CO2 emissions and embodied energy for a couple of alternative solutions. The results and energy performance simulations of the buildings use served as the basis for analysis and final guidelines concerning optimization of single family building volumes, including  summary conclusions describing how architectonic measures used within the  building design process can influence pro-environmental effects.
