A Simple Method for Evaluating the Sustainable Design of Energy Efficient Family Houses

Abstract

Buildings have negative effects on the environment throughout their life cycle, i.e. from the phase of obtaining raw materials and manufacturing materials and components up to the sale, building and use through the finai phase of removal when the building is decommissioned. In general, current legislation limits both the use of energy and the emissions allowed during operation, but does not limit the other parameters that define the design of contemporary sustainable buildings. Determining the sustainability of buildings should take place in the planning phase of the project, when it is still possible to influence the outcome. In this article, a simplified method using five chosen indicators Is employed to evaluate the level of sustainabiiity. The areas to be evaluated are energy efficiency, use of primary energy, CO2 emissions, costs, and the level of living comfort achieved. The evaluation using these indicators is carried out using three subjective and objective weighting methods, such that the final evaluation includes the viewpoints of an independent evaluator and the points of view of both the user and the state.In the case of an assessment of the five indicators for new constructions, it is ensured that the designs for the new building in energy c/ass A have the best total result of the assessment and therefore the best sustainable design, regardless of additional energy, environmental and economic Investment during the building phase. With a suitable choice of heat supply, even new buildings in energy c/ass C can come close to the effectiveness of a building design in energy class 6.

“…The advantages of wood as a construction material with lower embodied global warming potential, and embodied carbon positively associated with well-being, aesthetic and eco-friendliness, and realistic end-of-life disposal options (Praznik, Butala, & Zbašnik-Senegačnik, 2014).…”

The Issues of Residential House Systems and How to Make It More Sustainable Systems

“…electricity, fuel, gas, coal) is considered one of the key inputs in the house system, which is characterized by a broad interference with the system components. The use of energy for different house demands causes in produce a variety types of outputs including bills, CO2, hot air, and smog (4,5,6).…”

Eficiência Energética Com Base Nos Critérios Procel: Estudo De Caso Em Edifício Público

“…As construções têm uma grande parcela na agressão ao meio ambiente em termos globais. Representam, segundo autores como (Tianzhen Hong, Chou, & Bong, 2000); (Chen, Cook, & Crandall, 2013) (Praznik, Butala, & Senegačnik, 2014), uma das maiores consumidoras de recursos naturais, água e energia elétrica, além de ser uma das maiores geradoras de resíduos e de emissões de gases de efeito estufa. O Relatório do Programme des Nations Unies pour l'environnement (UNEP, 2011) aponta na mesma direção, colocando as edificações como consumidoras de alto impacto e potencialmente causadoras do aquecimento global.…”
