Introduction

Visible light is electromagnetic radiation that is perceived by the naked human eye, and is the core element of the sense of sight. However, lighting is one of the greatest consumers of electricity in a building, ranging from 20% to 50% of the aggregate energy consumption [1, 2]. There are various factors that affect the energy usage of lighting, but one of the main causes is the actual lamps. With this in consideration we can look at different aspects of lamps, namely: the comparisons…...

...principles of ZEBs (Zero Energy Buildings) to it. Another phase of the project deals with establishing an ideal ZEB design in Rajasthan, taking into account all environmental factors. At the heart of the project is the belief that Renewable Energy can be integrated with infrastructure. Various types of sustainable analysis have been considered for the project, to be done on the BITS Library as well as a prototype ZEB. A few of them are passive and active solar studies, wind simulation, material variation and so on. Software used to do this are: Autodesk Project Vasari and Ecotect Analysis. Also used will be RETScreen. The project involves the use Autodesk Ecotect Analysis 2013 and Autodesk Project Vasari as 3D modelling software that will help in designing of an ideal Zero Energy Building. The word “asymptotic” is used in the title of this project, because a ZEB is basically an ideal concept. It cannot be ideally achieved, the design can only tend towards achieving a net zero energy balance. Using the power of these 2 software, a case study of the “BITS Pilani Library, Pilani Campus” is to be implemented and remodelled according to the various codes defined by LEED (Leadership in Energy and Environmental Design) for ZEBs. Also, an ideal Zero Energy Building will be attempted using the same software tools. Buildings have a significant impact on energy use and the environment.

...Research Proposal in Technical Writing Tropical Design: An Eco-Friendly and Energy Saving Design for Residential Structure Submitted By: Gutierrez, Shiella Mae DL. Submitted To: Mr. Jesus Escuro 1st Semester 2011 Introduction Background of the Study “Do not fight forces, use them.” - (R. Buckmister Fuller) Tropical design is an environmentally conscious design technique in the field of architecture or simply described as designing with nature. This design minimizes the environmental impact of the building by enhancing efficiency and controls the use of materials, energy, and development space. There is an attempt to preserve air, water, and earth by choosing economically friendly building materials. Tropical design could contribute to the environment through its sustainable properties which minimizes too much use of electricity by using the natural energy as alternative. This research is conducted because it is a proof that both man and his natural environment can live in perfect harmony. The tropical conditions in the Philippines affect the high temperature, and low air flow which affect on the comfortable indoor environment. With this design approach, it can contribute to a sustainable lifestyle and culture. Tropical architecture can be a solution in preventing global warming because of its eco-friendly materials used in construction and the design itself. This design is important especially for those who are living in the tropics like the......

Greening the South Asian Economy

...South Asian Economic Students Meet 2012 | Agenda for Greening the South Asian Economy | Potential Energy Saving Capabilities of Emerging Cities: A Case of Hyderabad | L. Sai Anurag 11/10/2012 | Essay Proposal Since gaining Independence, the Indian Subcontinent has been one of the most promising areas for development and has increasingly made its presence felt in the global economic scenario with rapid progress in both the manufacturing and the services sector. India is the second fastest growing economy in the world, with a GDP growth rate of 9.4 percent in the financial year 2006-07. However, due to the impact of the global recession the policy paralysis in the country growth rate had fallen to 5.3% in Q4 FY’12. Contraction is the manufacturing sector and the falling rupee has deteriorated India’s position further. The resultant impact of the initial rapid GDP growth has been an increase in the per capita GDP and also an increase in the income levels of both rural and urban households. Achieving this growth also meant a tremendous rise in the use of energy across all the sectors of the economy as well albeit at a slower pace. The major point of concern here is not the magnitude of energy driving this growth but the quality and structure of this energy growth. India has immensely contributed to the growth of the South Asian Economy by taking up economic reforms and giving a tremendous boost to industry. India’s favorable demographic mix, its abundance...
