Abstract In this article the research is concentrated on defining the possibility and potentials of design to enhance the energy efficiency and refine the climate conditions in the existing residential buildings in Armenia. The digital model of existing residential building is used to calculate the annual energy consumption, by simulation software—Autodesk Green Building Student. The horizontal solar panel systems offered by local market leaders were applied to calculate the annual savings, the required installation area, prices, etc. Consequently, the actual efficiency of energy saving technological process of residential buildings in Armenia is estimated. Based on the applied strategies and obtained fact, some recommendations are made for residential buildings. This article is intended to help and to be stimulus for architects and constructors to consider and include green technologies in their new projects.

The Relationship

The green building certification system of Taiwan, EEWH (Ecology, Energy Saving, Waste Reduction and Health), has been in operation for more than 20 years (since 1999). In order to understand the relationship between green building certification and the construction costs of residential buildings, this study obtained 37 green building-certified residential cases and 36 general residential cases available from public information and conducted a comparative analysis. The results of this study showed that the average construction cost of a green building certification residential building was only 1.58% higher than a general residential building, indicating that green building certification does not require a large increase in costs. However, for residential buildings, achieving a high-grade (gold-grade or diamond-grade) green building certification means an increase of 6.7% to 9.3% in construction costs. This shows that the pursuit of higher levels of green building certification does require higher construction costs. In addition, the results of this study can not only provide important references for the government in making green building policies, but also offer a practical strategy for developers for decision-making.

ABSTRACT This study examines the daylight and energy performance of 27 external shading scenarios in a high-rise residential building in the urban tropics. The cooling energy, daytime lighting energy and the spatial daylight autonomy (sDA) of the building model were simulated in Rhino3D and Grasshopper simulation software. The best performance scenario (vertical and horizontal shading on the twentieth floor, horizontal shading only for the eleventh floor and no shading for the second floor) satisfied 75 sDA(300lx|50) with corresponding annual enery performance of 16%–20% in the cardinal directions. The baseline scenario, which is the current practice of providing balconies on all floors, reduced daylight to less than 75 sDA on the eleventh and second floor, even though it had higher annual enery performance (19%–24%) than the best performance scenario. Application of the design principles to a case study indicated that 58% of the spaces had over 75 sDA for both Baseline and Best performance scenarios, while an increase in enery performance of 1%–3% was found in the Best performance scenario compared to the Baseline.

Urbanization and technology have proven to be detrimental to the environment. Buildings contribute a significant portion of this damage. This issue motivated governments, builders, engineers, and architects to seek ways to reduce buildings’ environmental footprints. Leadership in Energy and Environmental Design (LEED), developed by the U.S. Green Building Council (USGBC), is one of the most widely used strategies to ensure energy efficiency and a clean environment in buildings. In Afghanistan, where there are no active regulatory frameworks for energy saving and efficiency for the building sector, it is imperative to promote the transformation of the building industry and practices towards sustainability. In this regard, the role of the residential building sector is of utmost importance due to its major share in the country’s energy consumption and GHG emissions profile. Thus, this study assesses the energy efficiency and environmental impact of existing buildings in Kabul city concerning the LEED rating system. This research suggests practical steps to improve the sustainability of the residential building stock in Kabul city. Robust sets of data on existing residential buildings in Kabul are collected, classified, evaluated, and compared to LEED standards. This research reveals and concludes that most of the existing buildings in Kabul city are in poor conditions and do not meet the minimum requirements to be a candidate for LEED certification. A detailed analysis of the results has led to recommendations on how these buildings could improve to meet the LEED criteria. This is the first study of its kind conducted for Kabul city residential building. Considering the cross-sectoral nature of the building industry, the findings of this study will contribute to many other areas such as water, transportation, ICT, health, energy and the environment.

Adjust measures to local conditions, use local materials, so there is no definite construction patterns and rules. In this paper a green residential buildings from Shenyang, focus on the analysis of the well insulated building envelope, radiant floor heating system with control system, solar hot water system in the building. At the same time, analysis of the energy saving technology can reduce energy consumption and CO2 emissions compare with "Residential building energy saving design standards "at Liaoning area. The project gives some experience to other designers in the process of green buildings design and promotes it constructed in the northeastern regions.
