ABSTRACT This paper introduces methodologies and optimal strategies to reduce the energy consumption of the building sector with the aim to reduce global energy usage of a given .region or country. Many efforts are underway to develop investment strategies for large-scale energy retrofits and stricter energy design standards for existing and future buildings. This paper presents a study that informs these strategies in a novel way. It introduces support for the cost-optimized retrofits of existing, and design improvements of new buildings in Turkey with the aim to offer recommendations to individual building owners as well as guidance to the market. Three building types, apartment, single-family house and office are analyzed with a novel optimization approach. The energy performance of each type is simulated in five different climate regions of Turkey and four different vintages. For each vintage, the building is modelled corresponding to local Turkish regulations that applied at the time of construction. Optimum results are produced for different goals in terms of energy saving targets. The optimization results reveal that a 50% energy saving target is attainable for the retrofit and a 40% energy saving target is attainable for new design improvements for each building type in all climate regions.

Background: The methods of heating houses with system components determine the energy-saving systems. Energy-saving solutions allow to maintain comfortable conditions in the house, while minimizing the cost associated with its operation and at the same time helping to protect natural environment. The examples of such solutions include condensing boilers, heat pumps and solar collectors.Material and methods: The object of the analysis in this paper is typical single-family house occupying the area of 150 m². The comparison of analyzed heating system for a single-family house, including modern energy sources, allows the assessment of the most cost-effective method of heating. Results: Choosing rational method of heating for a single-family house is dictated mainly by economic reasons. The efficiency of the heating sources is also very important. In addition, an important factor is a heating period, which depends on the weather conditions in a given year.Conclusions: The costs of fuel/energy are still growing. Fuel selection is determined mainly by fuel calorific value and the price. To select the type of the heating source one must take into account the cost of kWh of heat.

Abstract Summary: Combinatorial assembly of DNA elements is an efficient method for building large-scale synthetic pathways from standardized, reusable components. These methods are particularly useful because they enable assembly of multiple DNA fragments in one reaction, at the cost of requiring that each fragment satisfies design constraints. We developed BioPartsBuilder as a biologist-friendly web tool to design biological parts that are compatible with DNA combinatorial assembly methods, such as Golden Gate and related methods. It retrieves biological sequences, enforces compliance with assembly design standards and provides a fabrication plan for each fragment. Availability and implementation: BioPartsBuilder is accessible at http://public.biopartsbuilder.org and an Amazon Web Services image is available from the AWS Market Place (AMI ID: ami-508acf38).

Steady State Method

Energy certification of buildings in Serbia was introduced in 2011 and energy label depends on energy need for heating per unit floor area of heated space, calculated by the fully prescribed monthly quasi-steady-state method defined by ISO 13790. In the Republic of Serbia, most of families live in single-family houses built before the energy certification of buildings was introduced. Therefore, the estimation of energy performance of the existing buildings is important for labeling, and evaluation of energy saving measures and energy strategies to be implemented. This paper examines the applicability of monthly method defined by National legislation on the existing buildings stock in Serbia, by comparing it to the more accurate dynamic simulation method. Typical single-family houses are taken as a test case, since they are responsible for about 76% of energy consumption for heating. The results show that the dynamic simulation method estimates 21% to 54% higher energy need for heating, compared to the monthly method. Also, the monthly method estimates up to 13% higher savings by typical building envelope energy saving measures, compared to the dynamic simulation. This paper recommends improvement in procedures for calculation of building energy performance index to better assess energy consumption, effects of energy saving measures, and create solid background for developing and implementing of energy saving strategies.

Structural Insulated Panels (SIPs) have the potential to provide well insulated and air tight homes and thus better energy performance than the conventional wood-frame construction. Currently a SIP home is slightly more expensive to build than a conventional wood-frame home. This paper summarizes the results of a detailed study to compare the energy consumption of both SIP and wood-frame houses in representative climate zones across the United States. A simplified method to estimate the potential energy savings associated with SIP homes relative to an equivalent wood-frame home is developed and presented. As an application of the simplified method, a life cycle cost analysis was conducted to assess the cost effectiveness of building SIP homes throughout the US.

Insulation Performance

Building designs should be reviewed from the aspects of both design aesthetics and energy performance. The installation of insulation materials in external walls, roofs, and floors is a basic method that could reduce energy losses from buildings. The purpose of this study is to investigate the types of insulation materials selected as building materials and the insulation performance of each building elements when designing new buildings in South Korea. The insulation performance of the external walls, roofs, and floors of buildings were compared with the insulation criteria of the Energy Saving Design Standards of Buildings in building energy code. The design documents, as well as drawings and building energy saving plan sheets, which are required to be submitted for buildings larger than a certain size in South Korea, were collected. The most widely used insulation material in multi-family housings and non-residential buildings was extruded polystyrene (XPS). The insulation performance of external walls, roofs, and floors were higher than that established by design criteria of building energy code. In particular, the external walls had roughly a 25.5% better insulation performance than the insulation criteria.

The purpose of this article is to analyze the efficiency of management of an apartment building in the context of energy efficiency. The article describes the conduct of an energy audit for apartment buildings, which allows a thorough assessment of this problem and identify optimal ways to save energy resources by apartment buildings. Energy audit is a special examination of residential buildings or enterprises, conducted by specialized specialists in energy certification of buildings to determine their technical condition and energy efficiency. Methodology. Within the framework of this article, the results of a sociological survey conducted among the heads of condominiums to analyze the level of their interest in the implementation of energy efficiency measures were analyzed. The value of the cost of 1 apartment for the implementation of the energy modernization project is calculated. Currently, "energy efficiency" and "energy saving" are extremely popular in Ukraine, due to the following: increasing the cost of energy resources;limited financial capacity of vulnerable groups to pay for services. Results of the survey showed an insufficient level of implementation of energy-saving technologies, although the level of interest of apartment building heads is very high. The development of energy efficiency programs for an apartment building is carried out not only taking into account the necessary priority measures, but also based on the financial capacity of the co-owners of the apartment building. The reason for the insufficient implementation of energy saving measures is the insufficient financial capacity of co-owners and, as a consequence, the apartment buildings themselves. State support for the implementation of energy efficiency in the management of apartment buildings has been studied in detail. It is concluded that large-scale involvement of apartment buildings in the implementation of energy efficiency programs is constrained by the following problems: insufficient funding; insufficient state support for project financing; distrust of co-owners to the effectiveness of the project; unsatisfactory condition of the apartment building, which requires significant financial costs. The growth rate of the number of condominium applications shows an increase in public confidence in the Program. However, they are not enough to talk about launching large-scale energy modernization of multi-apartment housing. Financial support of local authorities to their residents in the implementation of energy saving measures will contribute to even better results.
