“…Wall type with sandstone on the inside has obtained a reduction of 2 °C in the indoor peak temperature. This is because sandstone has the maximum density and hence the highest thermal mass, which implies that heavier the material, more heat would be required to change the temperature of that material [13], [14]. Although aerated brick has a greater thickness compared to concrete, yet its specific heat and density is low, hence, has a better cooling performance giving a decrease of 1 °C in the peak daytime temperature.…”

-A large proportion of the world's population resides in developing countries where there is a lack of rigorous studies in designing energy efficient buildings. This study is a step in designing a naturally ventilated high rise residential building in a tropical climatic context of the developing country, Pakistan. Karachi, the largest city of Pakistan, lies in the subtropical hot desert region with constant high temperature of average 32 °C throughout the summer and no particular winter season. The Design Builder software package is used to design a 25 storey high rise residential building relying primarily on natural ventilation. A final conceptual design is proposed after optimization of massing, geometry, orientation, and improved building envelope design including extensive shading devices in the form of trees. It has been observed that a reduction of 8 °C in indoor ambient temperature is possible to achieve with passive measures and use of night time ventilation. A fully naturally ventilated building can reduce the energy consumption for cooling and heating by 96 % compared to a building using air conditioning systems.

“…In their study Çe-lik et al (2011) used the EPB-TR method to determine the heating-cooling energy requirements of a chosen building based on exterior wall heat conductivity, window characteristics and draft rates and presented the effect of these factors on energy savings. Cheung et al (2004) demonstrated the effects of modifications on the building envelope in order to reduce cooling loads of a high-rise residential building. A 31% saving was achieved in annual cooling energy consumption by improvements on exterior walls, window characteristics and shading effects.…”

5 Türkiye'de kentleşme sürecinde plansız yapılaşma ve bina yapım maliyetlerinin düşük tutulması gibi unsurlar konut binalarında enerji tüketiminin Avrupa Birliği ülkeleri ortalamalarının iki katı gerçekleşmesine neden olmaktadır. Bu gidişat karşısında Türkiye'de 2007 yılından itibaren Enerji Verimliliği Kanunu ve Enerji Performans Yönetmeliği uygulamaya konularak, mevcut konut binalarının enerji tüketimi-kabuk ilişkisindeTurkey has undergone inadequate development during a process of rapid urbanization and growth since the 1950s, parallel to reduced construction costs for residential buildings. This has contributed to household energy consumption in Turkey growing to twice the global average, and twice the averages of European Union member states. In response, the Energy Efficiency Law and other energy performance regulations were enacted in 2007. As a part of "Assessing the Inventory for Renewable Energy Utilization in Existing Residential Buildings and Setting Up Local Design Parameters," supported by the Yıldız Technical University Scientific Research Projects Coordination Department, İstanbul's Beykoz District was chosen as the case area. Using solar energy for heating purposes is popular in Beykoz for a number of reasons, including the prevalence of mostly detached buildings and abundant green space, as well as less building density and fewer stories, compared to the city center. Four buildings were studied in order to identify improvements that would allow for a reduction in cooling and heating loads in existing residential buildings in the context of building envelopes. Research of the four existing residential buildings executes similar results. Results of the study of a multi-family residential building in the neighborhood of Kanlıca is presented. Determined by the calculation of cooling-heating loads and carbon emissions, improvements designed to efficiently utilize solar energy where the building envelope permits are identified. These improvements address window space, eaves, and characteristics, as well as exterior wall insulation thickness, draft prevention, shading, landscaping features, and control of solar energy. Average monthly and annual heating-cooling requirements were calculated using IESVE simulation software. The improvements yielded a 72% drop in annual heating energy consumption and a 24% drop in annual cooling energy consumption, resulting in an average drop of 62% in CO 2 emissions. ARTICLE

“…Earlier research conducted by [30] found out that thermal comfort is affected by the thermal interaction between the building and external environment. Researcher [31] had conducted research on the impacts of architectural components on energy consumption in mechanically ventilated building as well as its health related effects on the performance of building occupants. Although there were many research conducted on the effects of external building envelope and its influence to the indoor air quality, intelligent façade design solutions in hot and humid climate have been barely studied compared with those in cold climate [32].Nevertheless, a variety of green building certification systems had been introduced worldwide but one question remains to be clarified: are the scheme currently applied in green building certification fostering buildings of Indoor Environmental Quality satisfying their occupants?…”

Abstract. During the past decade, the construction industry has seen a new trend in the development of "green" or "sustainable" construction concept around the world with vast support from prominent organization, together with the introduction of sustainable building codes. The establishment of green building certification systems worldwide is seen as one of the most efforts in the emerging green building movement. In order to support the development of the "green" and "sustainable" concept in Malaysia, Green Building Index (GBI) was launched by the government on 21 May 2009 that created to promote sustainability in the built environment and raise awareness of environmental issues. However, the construction industry seems to have focused only on findings the "right mechanism" for an environmentally sustainable "final result" in order for the building to be certified as green with the lacking of continuous assessment on the building performance after the certifications. This study is purposely conducted to investigate the performance of various rated Green Building Index (GBI) Non-Residential New Construction office buildings and the influence on Indoor Thermal Comfort (ITC) of the selected buildings. The aim is to develop an assessment framework for optimum green building architectural façade to be used for office buildings in Malaysia as well as to analyse the occupants' perception, satisfaction and performance in the selected Green Building Index (GBI) rated office indoor environment. This research is still in its infancy; therefore the paper is focused on research aims, research scope and methodology, and expected deliverables for the proposed research.
