Sustainable facade for commercial buildings Madhur Agrawal, Ar. Preeti Kale Dr. D.Y. Patil College of Architecture, Akurdi, Pune. Email: madhuragrawal1208@gmail.com Abstract :Nowadays it becomes very essential to practice sustainability. As you know most of the buildings have full glass façade which trap heat; make human discomfort and increase the consumption of air conditioning. The aim of this research paper is to make people aware of the right façade design for their climatic region. So The objective of this paper to study the different types of material and technologies and how to reduce the mechanical sources of ventilation also, it should be costeffective, durable, climate-responsive, and aesthetically pleasant which helps us in designing the most sustainable façade for commercial buildings.

Key words: Sustainability; carbon footprint; human comfort; climate-responsive; façade; thermal comfort; I.

INTRODUCTION

These days most of the commercial building just adopting the western façade technologies; Providing glass façade is become very common but it adversely affecting environment. Energy consumption in commercial building increase sufficiently. More no. Of Air conditioner are widely used to make human comfort but it affecting the people health it makes peoples sick and people becoming dependent on mechanical mean of ventilation. The connection between indoor to outdoor atmosphere is become less. For good health human need good natural light and ventilation by designing sustainable façade we can achieve good human comfort and it also decrease the energy consumption and carbon footprint. For different climate zone different strategy is used. As this research paper is limited to Pune, Maharashtra region only. Façade is one of the building elements which can contribute to consume energy and human comfort within building. Energy and natural resource are depleting rapidly, so it is becoming important to study and designing façade which reduce the energy consumption and makes human comfort. By studying the climate of Pune, we come to know that Pune has hot semiarid climate, using the strategy for this region will give us most suitable sustainable faced for commercial building. Façade must follow these functions: • Provision of view to the outside. • Resistance of force from the wind load. • Bearing its own weight. • Implementation of daylight strategies to Minimize use of artificial source of lighting. • Protection from solar heat gain (harmful radiation). • Protection from noise. • Resistance to rainwater and moisture penetration.

MATERIAL AND METHODOLOGY

Selection of right material for the sustainable façade designing plays major role. In sustainable façade design there are two important factors to consider are as follow: • Improve thermal performance of building envelops. • Minimize thermal bridging. Thermal bridging inside a wall happens wherein a fantastically conductive cloth, including a steel help, penetrates the façade’s insulation layer. This may notably affect the thermal overall performance of the wall, and lower its powerful thermal resistance (Lawton et al., 2010). Thermal bridging can occur in all sorts of facades. Thermally unbroken aluminum mullions in curtain walls are rather conductive and transfer warmth from the outdoors to the indoors, lowering the general thermal performance of the facade. Fabric choice also has an environmental effect. It is becoming increasingly essential to pick materials that have the least poor effect on the surroundings. The existence-cycle assessment method may be used to determine environmental impacts of fabric selection, in which material contents, production techniques, energy necessities, and waste are analyzed to identify the real value of a cloth, reflecting the total amount of its environmental effect (ISO, 2006). Selecting materials based totally on the embodied strength information is also the correct approach for thinking about environmental effects. The embodied electricity is the quantity of power required to extract, method, transport, set up, and recycle or remove a fabric, and is commonly measured in keeping with mass or volume of the fabric. While evaluating the embodied energy of facade systems, the measurements have to be based totally on location in preference to mass or quantity, considering the embodied energy of character additives and materials of the façade. Different types of sustainable façade technologies, both currently used as well as futuristic approaches will be studied in detail. Analysis of the thermal behavior of different façade systems and materials along with case studies of façades from varying climatic zones will be carried out. III.

CASE STUDY

The selected buildings have been already evaluated using one of the score structures or standards for high-overall performance homes, and their power overall performance statistics (metered or simulated) become available. The
