The goal of this paper is to calculate of thermal physical and environmental parameters of lower structure to support decision at the design phase of the project. The solutions are towards reduced embodied environmental impacts and improved energy performance. This study uses life cycle analysis in system boundary from Cradle to Gate and focuses on environmental indicators such as embodied energy and emissions of CO2eq. and SO2eq. The selection and combination of materials influence amount of energy consumption and associated production of emissions during building operation phase.
Energy-efficient buildings utilise the potential of renewable sources, among which heat pumps hold an important position. As this technology has a secondary effect on the environment through its noise immission, locations of outdoor units in the exterior should be subjected to the assessment. The present article deals with the options of placing heat pumps in the exterior and the placement assessment methods. The noise burden identification through the assessment of the time exposure is presented in the example of an in situ measurement.
