Summary

A large percentage of most countries’ energy demand goes to power its buildings. Urbanization will only increase building constructions and, in turn, cause an increase in energy demand. Designing buildings that are self-sustained is, therefore, logical and very important. A building that can satisfy its own energy needs, by generating the energy it requires, is called a Net Zero Energy Building and The Puma Sustainable Store at Bangalore is the first such designed showroom in developing India. This building incorporates a lot of sustainable features in architectural and engineering design: recycled steel in concrete and locally designed porotherm blocks made from waste silt are used in construction; high performance glazing, recycled bamboo, earth air tunnel for free cooling to reduced air conditioning load by 10.3%, 30%-40% reduction in lighting power density, natural daylight achieving illuminance levels of minimum 270 lux in 75% of the interior spaces, CFD techniques to determine optimised diffuser locations for the under floor air distribution system, etc. are some of the concepts incorporated in this project. Water is recycled in a sewerage treatment plant and reused for landscaping and flushing requirements. CO2 concentrationdependent demand control ventilation system is used to keep the air quality in check. Solar photo-voltaic panels are installed to generate the energy required to operate the building. The designed annual energy consumed by the ground, first and mezzanine floor was determined to be 41,895 kWh. The energy generated by the solar photo-voltaic was designed to be 42,000 kWh per year. The energy demand of the building was then calculated to be 37.62 kWh/m2-yr.
