“…We established a building lifetime of 100 years. This is consistent with the age of buildings as revealed in a Spanish housing census conducted by the National Statistics Institute (INE) ( Rudbeck, 2002;Johnstone, 2001aJohnstone, , 2001bDavies and Wyatt, 2004;and Article 19 ECO 805/2003). The maintenance costs to maintain the energy rate during the dwelling's lifespan were considered, as was both the economic cost and the specific time when maintenance had to be done.…”

Energy consumption in homes produces CO2. In many countries, building regulations are being set to enable energy efficiency performance levels to be issued. In Spain, there is a regulated procedure to certify the energy performance of buildings according to their CO2 emissions. Consequently, some software tools have been designed to simulate buildings, and to obtain their energy consumption and CO2 emissions. In this paper, investment, maintenance and energy consumption costs are calculated for different energy performance levels and for various climatic zones in a single-family home. According to the results, for buildings to be more energy-efficient, higher construction and maintenance costs are implied, which are not compensated by lower energy costs. Therefore under current conditions, economic criteria do not support the improvement of a dwelling's energy efficiency. Among the possible measures to promote energy efficiency, a price for CO2 emissions is suggested, including the social cost in the analysis. For this purpose, the cost-optimal methodology is used. In different scenarios for the discount rate and energy prices, various prices for CO2 are obtained, depending on climatic zone and energy performance level.

“…This cost allows estimating the cost per year. The service life for the whole building is considered to be 100 years, as confirmed in various sources (Rudbeck, 2002;Johnstone, 2001aJohnstone, , 2001bDavies and Wyatt, 2004;Article 19 ECO 805/2003). This fits the observed ages of buildings from the Spanish building stock, according to data from the Spanish National Statistics Institute.…”

Versión / Versió:Pre-print requirements, leaving a significant amount of room for the Member States to establish their specific mechanisms, numeric requirements and ways to implement them, taking into account local conditions. With respect to the Spanish case, the search for buildings that are more energy efficient results in a conflict between users' economic objectives and society's environmental objectives. In this paper, Compromise Programming is applied to help in the decision-makingprocess. An appropriate distribution of types of dwellings, according to their energy performance and to the climatic zone considered in Spain, will be suggested. Results provide a compromise solution between both objectives.

This work presents the analysis of installation options of exploitable car park roofs offered by the designers, material manufacturers and suppliers and introduces the Lithuanian legislation with the requirements for this type of roofing. Reasons of the most frequently occurring defects have been examined and several options for correcting defects have been provided. The most cost-effective option for correcting the defect in question has been chosen. Practical measures for increasing the reliability of exploitable car park roofs have been proposed. The analysis has shown that at a minimum slope reliability of the exploitable roof coated with roller heat-welded materials is not guaranteed. The authors propose to tighten the requirements on car park roofing.
