“…Table 3 shows the thermal transmittance according to the January climate zone for each element of the thermal envelope of the building and the corresponding exchange surfaces. The compositions of the different elements that make up the building enclosures and their main characteristics, as well as the compositions of the building openings, were reported in [30], where Cádiz and Valencia correspond to January climate zone W, Cáceres corresponds to January climate zone X, Madrid corresponds to January climate zone Y and León corresponds to January climate zone Z.…”

“…The residential building studied is the multi-family housing block that was used in [7,28,29] to assess the energy and environmental impacts of the EPBD in Spain. The existing thermal envelope of the building has the main features of the thermal envelopes of the existing residential stock in the studied areas [30]. The methodology developed includes the evaluation of the main energy and environmental parameters of the renovated buildings to be able to compare the obtained solutions with other different energy renovation solutions.…”

Energy Renovation of Residential Buildings in Cold Mediterranean Zones Using Optimized Thermal Envelope Insulation Thicknesses: The Case of Spain

The residential sector of the European Union consumes 27% of the final energy of the European Union, and approximately two-thirds of the existing dwellings in the European Union were built before 1980. For this reason, the European Union aims to transform the existing residential building stock into nearly zero-energy buildings by 2050 through energy renovation. The most effective method to achieve this goal is to increase the thermal insulation of opaque elements of the thermal envelope. This study aims to assess the energy, environmental and economic impacts of the energy renovation of the thermal envelopes that are typical of the existing multi-family buildings of the 26 provincial capitals in the cold climate zones of Spain. To achieve this goal, the insulation thickness to be added to the walls, roof and first floor framework is optimized by a life cycle cost analysis, and the existing building openings are replaced, thus minimizing both the total heating costs and the total heating and cooling costs. The study uses four thermal insulation materials for four different heating and cooling systems in 10 different models. The results obtained will be used to propose energy renovation solutions to achieve nearly zero-energy buildings both in Spain and in similar Mediterranean climate zones.

“…The author has stated that the use of biomass for heating should be considered in the early stages of the building's design. A study of biomass boilers heat generation in residential buildings in Spain has been reported by Las-Heras-Casas et al [3]. The authors have stated that biomass use in residential sector could assist in the achievement of EU's 2020 goals for climate and energy.…”

The necessity to cope with the global threats of climate change has increased our concern on the energy sources used increasing the share of renewable energies and shifting from fossil fuels to benign energy sources. European Union through various directives aims at increasing sustainability in buildings reducing their energy consumption, fossil fuels use and carbon emissions. In this context, the use of renewable energies covering all the energy needs and zeroing the carbon footprint in a residential building located in northern Greece has been investigated. Use of locally available sustainable energies including solar energy, solid biomass and waste heat rejected from power plants has been proposed for covering all the energy needs in a house. Their technologies for heat and power generation are mature, reliable and cost effective. Results have indicated that the combined use of the abovementioned sustainable energies can cover all the energy needs in the building, zeroing its carbon emissions due to operating energy use. The investment cost for a house at 150 m 2 varies between 6200 € to 10,700 € or 41.33 to 71.33 € per m 2 of the building covered surface, which is relatively low compared with its construction cost. Therefore, the creation of zero CO 2 emissions residential buildings due to energy use in northern Greece is technically and economically feasible.

“…Indeed, a level 1 energy efficiency retrofit program, targeting only the existing residential building stock, reduces electricity consumption by 10,054 GWh/year, peak demand by 2290 MW and carbon emission by 7.611 million tons/year. Las-Heras-Casas et al [30] explores the substitution of central fossil fuel boilers (heating oil, liquefied petroleum gas, and natural gas) with central biomass boilers to cover all heating and domestic hot water needs in multi-family buildings in Spain. Typical buildings from five cities, located in each different climate zone of the peninsular winter, were chosen for this study.…”

Interlinked Sustainability Aspects of Low-Rise Residential Family House Development in Slovakia

This paper compares the sustainability aspects of three family houses according to the Slovak building environmental assessment system (BEAS). Various categories of family houses were evaluated, including site selection, project planning, building construction, indoor environment, energy performance, and water and waste management. Based on the results, Family Houses 3 and 2 are certified as BEAS SILVER, with scores of 2.46 and 2.01, respectively. Family House 1 is certified as BEAS BRONZE, with an overall score of 1.44. The results show, not only the importance of the site in terms of availability, connectivity to the network and the potential to use renewable energy sources, but also the importance of the design and construction of the building, including the application of environmentally friendly building materials, ensuring the quality of the indoor environment and the energy efficiency of the building. The aims of this study were to highlight the current trend in the design and construction of low-rise residential family houses in Slovakia and to identify gaps in the design and construction of key sustainability aspects through the existing building environmental assessment system. In the future, many low-rise residential family houses will be assessed to modify and validate BEAS.
