The progressive development of the economy of the Republic of Kazakhstan is impossible without solving the issues of increasing energy efficiency and energy conservation. These issues are very relevant in the construction sector of Kazakhstan. Housing facilities, on average, consume 2-3 times more heat per square meter, than buildings in Europe. However, in Kazakhstan until now there is no methodology for determining the energy efficiency of buildings and structures that meets modern requirements. The methodology discussed in this article is harmonized with EU requirements and establishes a method for calculating the annual energy consumption of buildings for heating, hot water, ventilation and air conditioning, taking into account auxiliary energy for the operation of these systems, and is intended for use in the design of new construction, reconstruction (modernization) residential and public buildings, as well as operated buildings and structures.

Building construction systems that come in different forms and types need to be properly selected before being use, this may have different impact on overall embodied energy of the building construction. Hence, in order to achieve and maximize the construction contribution, the designer plays a big role in choosing the appropriate energy efficient construction. The designers need to be equipped with the right knowledge and tool which gathers a possible range of embodied energy indicators in order to select energy efficient construction. This paper aims at confirming the Malaysian common construction systems and compares it with the historical literature while it also explore energy efficiency in building construction. It is based on the common construction knowledge and also on the published literatures through a critical review of the possible range of embodied energy indicators and construction systems. The study demonstrated and confirmed that Malaysian common building construction systems can be categorized into six groups: Structural frame, Slab, Internal wall, External Wall, Roof and Staircase. This finding is highly significant for the future design in the area of energy efficiency.

Abstract Design of new modern systems for low energy efficient construction in a passive, zero standard or energy-autonomous buildings, as well as the increased popularity of solid wood construction means intervention into the very structure of its statics, building physics, but also fire properties. Some prototype design solutions are not verified whether the tests, by good computational analysis or verification of long-term use of the building. In the context of changing standards in building design, new approaches are needed. If in wooden buildings the potential risk of fire is higher than other buildings, we need special methods, materials and practical skills.

RESUMO: Nos últimos anos, em virtude das preocupações com a eficiência energética das edificações, a adequação da arquitetura ao clima ganhou maior importância. Sendo que, uma das formas de tornar uma construção eficiente energeticamente, é através da utilização de estratégias de condicionamento passivo, destacando-se a ventilação natural para o clima quente e úmido. Neste contexto, o presente trabalho apresenta a simulação computacional de uma edificação unifamiliar, naturalmente ventilada, realizada por meio do plug-in Archsim, para a cidade de Teófilo Otoni – MG, utilizando-se, para tanto, os dados climáticos do TRY (Test Reference Year). As alternativas adotadas nas simulações consistiram em variar a disposição e a área de ventilação das aberturas, verificando a influência destes parâmetros no desempenho térmico da edificação. De acordo com os resultados obtidos na simulação pode-se dizer que a melhor orientação para as aberturas é na direção leste-sul com área de abertura para ventilação natural de 20% da área do piso. Para esta composição a porcentagem de horas de conforto para a edificação é de 57,5% e o desconforto térmico anual é de 42,5% das horas. A principal contribuição deste artigo consiste na análise da utilização da ventilação natural em edificações de pequeno porte e seu impacto no conforto térmico do usuário, apresentando ainda a importância da utilização de simulações computacionais como ferramenta de auxilio no projeto arquitetônico.
 
 ABSTRACT: Concerns related to energy efficiency in buildings in recent years, induced the increase of architectural adaptation to climate. The use of passive conditioning strategies, emphasizing natural ventilation for hot and humid climate is one way to have an energy-efficient construction. In this context, this paper presents a computer simulation of a single family building, naturally ventilated, held by the plug-in Archsim to the city of Teófilo Otoni - MG, using the climate data TRY (Test Reference Year). The alternative adopted in the simulations consisted in varying the layout and area of ventilation openings, checking the influence of these parameters on the thermal performance of the building. According to the results obtained in the simulation, the best orientation for the openings is in the south-east direction with opening area for natural ventilation of 20% of the floor area. For this composition the building comfort hours’ percentage is 57.5% and the annual thermal discomfort is 42.5% of the hours. The main contribution of this paper is the analysis of the use of natural ventilation in small buildings and its impact on the thermal comfort of the user, showing the importance of using computer simulations as an aid tool in architectural design.

The article identifies the main conditions and problems of introducing energy-efficient technologies for business in Ukraine and considers the design experience of building green commercial buildings that have been erected in recent years (innovative parks UNIT.City in Kiev and LvivTech.City in Lviv, on the Sobachie mouth peninsula, Astarta Business Center in Kiev, etc.) It has been established that the main problem of introducing energy-efficient technologies in public commercial projects is the insufficient participation of the state in financing and stimulating business. To establish this process, it is necessary to amend the legislation on land, on technology parks, on the procedure for taxation and subsidies to enterprises that develop energy-efficient technologies in construction at different levels. The features of Ukrainian development and the dependence of the profitability of the building on the quality of the architectural solution are considered. It has been found that energy-efficient technologies are of interest only to a small fraction of commercial real estate developers who are focused on the development of the IT industry. To be able to deploy economically feasible energy-efficient commercial projects in other sectors, both state support and business entry into foreign investment markets will need additional guarantees and reduce the risk of waiting for a 10-15-year payback period for large-scale innovative projects. It was revealed that the IT industry has become a catalyst for the development of innovations in the field of energy-efficient construction. Thanks to it, architects were able to realize energy-efficient public buildings of the commercial sector, which are the prototypes for further similar design in Ukraine and the basis for developing the principles of "green" construction, the main provisions of which can be reflected in the changes to the state building standards of Ukraine.
