#BUILDING ENVELOPE ANALYSIS SKIN#

High performance facades dont act as barrier between interior and exterior environment rather they participate as active systems in minimizing building energy consumption by responding to external environmental conditions.Īs climate plays a vital role in building energy performance all guidelines related to climate must be taken into considerations while designing High Performance Building Facadesĭesign Strategies for high performance facades in Hot & Humid regions are quite different from those in Hot & Arid regions. High performance building facades are building envelops that use minimum amount of energy to maintain comfortable indoor environment for occupants as well as improves occupants health and productivity. Opaque components roofs, walls, slabs on grade (in touch with ground), opaque doors & basement walls.įenestration Systems windows, sky-lights, ventilators and doors that are more than half glazed.

The performance indices and parameters have been taken from NBC 2016 and ECBC 2017.Manual calculations are being done for the findings and recommendations are given.ĭESIGN METHODS ACCORDING TO CLIMATIC CONDITIONS FOR HIGH PERFORMANCE BUILDING ENVELOPEīuilding envelop integrates exterior building skin and roofs which comprises opaque components and fenestration systems. To know about the indices of assessing Thermal Performance of Building EnvelopeĪctual Meaning of the indices and to figure out whether all the indices are affected by design/orientation, material and the amount of solar exposure.Įxtensive studies have been made on several research papers. To find out the Impact of Solar time and local clock time on received solar radiation in different directions by giving an example Numerous researches have been done on quantification of various parameters of heat transfer but each parameter will not be giving the same results in each & every climate and for designing, the designers should know the fundamentals of these parameters and which parameter they should focus more on in terms of achieving the required outcome for a specific climate. The paper will also give the measures for the overall performance of Building Envelope and Building envelope techniques to reduce the energy consumption. The purpose of this paper is to find out the appropriateness of various principles according to the climate and methods to do the climate analysis. Heat transfer from outside to inside takes place through the Building Envelope and the quantities are derived through certain basic principles. INTRODUCTION AND STATEMENT OF THE PROBLEM Key words – Solar heat gain ,U-value,R-value,Thermal Time Constant, Thermal Damping, Thermal Performance Index, Building Index Numerous technologies are being developed to generate energy also. These facades also have benefits other than energy saving.

To achieve this goal an integrated approach is required which comprise techniques, technologies, architectural innovation all together. This paper also focus on new facades technologies which lower down the buildings energy demand with better insulation. This paper deals with the improvement of thermal performance of Building Envelope according to climate, indices and local solar time of region. Building envelope is the first to encounter with weather thus it plays a major role in deciding buildings energy demand. To handle the issue it is important to deal with buildings energy demand which is mainly due to extreme weather conditions. Abstract – In the era of raising environmental problems, built structures are considered as one of the main energy consuming entities which are ultimately responsible for environmental degradation.
