SUSTAINABLE HOUSING

1. INRODCUTION

Buildings, as they are designed and used today, contribute to serious environmental problems because of excessive consumption of energy and other natural resources. The close connection between energy use in buildings and environmental damage arises because energy-intensive solutions sought to construct a building and meet its demands for heating, cooling, ventilation, and lighting cause severe depletion of invaluable environmental resources.

However, buildings can be designed to meet the occupant’s need for thermal and visual comfort at reduced levels of energy and resources consumption. Energy resource efficiency in new constructions can be affected by adopting an integrated approach to building design.

Thus, in brief, an energy-efficient building balances all aspects of energy use in a building – lighting, space-conditioning, and ventilation – by providing an optimized mix of ive solar design strategies, energy efficient equipment, and renewable sources of energy. Use of materials with low embodied energy also forms a major component in energy efficient building designs.

2. ABSTRACT Demand for energy is increasing fast day by day and is likely to increase in tune with industrialization/ urbanization. The building sector being one of the largest consumers of energy, has gained prominence over the past few decades. Buildings for 33 percent of the total electricity consumption in India. An estimated 70 percent of the buildings stock required for 2030 is yet to be built. This formidable growth in the construction industry and the resultant energy demand will increase dependence on imported fuel, contribute to higher greenhouse gas (GHG) emissions, and strain the country's fossil fuel dependent infrastructure. It is essential to take energy efficiency measures. Implementing minimum energy performance standards for buildings will contribute towards checking the increasing energy demand, hence energy efficiency goals are needed for energy security.

3. WHAT IS THE NEED OF SUSTAINABLE HOUSING

By reducing buildings’ energy consumption, a nation can reduce dependency on imported energy and strengthen its strategic position. Moderation of energy-end use in buildings will reduce greenhouse gas emissions and pollution produced by the combustion of fossil fuels. This environmental benefit appears on two scales, local and global. Because much of buildings’ demand for energy requires local energy combustion in individual heating systems or district heating, reduced energy demand improves air quality at the local level.

When adequately ventilated, energy efficient buildings are generally healthier than traditional buildings. Relative to traditional buildings, energy efficient buildings offer a more stable indoor climate, with less draught from windows, walls, floors, and ceiling constructions. Because residents of energy efficient buildings must spend relatively less to heat and cool their homes to within the margins of acceptable comfort, energy efficient construction reduces fuel poverty across society. As households demanding less energy for building-related uses, they burn less fuel locally, thus doubling the potential to improve public health and otherwise benefit local communities.

5. OBJECTIVE

•

Incorporate solar ive techniques in a building design to minimize load on

conventional systems (heating, cooling, ventilation, and lighting).

•

Design energy-efficient lighting and HVAC (heating, ventilation, and air-

conditioning) systems.

•

Use renewable energy systems (solar photovoltaic systems / solar water

heating systems) to meet a part of building load.

•

Use low energy materials and methods of construction and reduce

transportation energy.

6. SCOPE OF THE PROJECT Energy efficiency is quickly becoming a sought after goal for many buildings around the globe - each relies on exceptional energy conservation and then on-site renewable to meet all of its heating, cooling and electricity needs. Yet the true performance of many developments is overstated – and actual Energy Efficient buildings are very few.

7. METHODOLOGY This research is small-scale with the objective to merely explore the subject and investigate the possibilities of undertaking a larger research study, which makes it an explorative research with the objective to make tentative conclusions at the end. The approach way will have a profound effect upon the way research is done, so this section discusses the types of research which can undertake for thesis. The use of literature and case studies is considered and the merits of primary research are debated and advice is given on the use of existing research data. One may not be fond of statistics, but the potential relevance of a quantitative approach should be considered and similarly, the idea of qualitative analysis and conducting the research may yield valuable data. The possibilities of using quantitative and qualitative data are also discussed. PRELIMINARY RESEARCH A bit of preliminary research will help to plan out thesis which determines what kind of sources is needed for the thesis. BUILDING CODES FOR ENERGY EFFICIENCY, US This highlights the benefits of building energy codes and describes several steps that parties working under the National Action Plan for Energy Efficiency can take to advance cost-effective energy efficiency through the adoption, implementation, and enforcement of codes. INTERNATIONAL ENERGY CONSERVATION CODE

The IECC addresses energy efficiency on several fronts including cost savings, reduced energy usage, conservation of natural resources and the impact of energy usage on the environment. THE ENERGY AND RESOURCES INSTITUTE (TERI) TERI is a research institute focusing its research activities in the fields of energy, environment and sustainable development. LEADERSHIP IN ENERGY AND ENVIRONMENTAL DESIGN (LEED) LEED is an internationally recognized green building rating system.55 LEED verifies that a building was designed and built using improved performance strategies, including energy savings, water efficiency, and carbon dioxide emissions reduction. GREEN RATING FOR INTEGRATED HABITAT ASSESSMENT (GRIHA) GRIHA is the national rating system for green building design, developed and implemented by The Energy and Resources Institute (TERI) and the Ministry of New and Renewable Energy (MNRE). ENERGY EFFICIENCY REQUIREMENTS IN BUILDING CODES, ENERGY EFFICIENCY POLICIES FOR NEW BUILDINGS, INDIA Energy efficiency requirements in building codes can ensure that concern is taken for energy efficiency at the design phase and can help to realize the large potentials for energy efficiency in new buildings. Energy efficiency requirements for new buildings are set in different ways. Based on national or local traditions they can either be integrated in the general building codes or standards for new buildings, or they can be set as separate standards for energy efficiency.

ENERGY CONSERVATION BUILDING CODE, INDIA The purpose of Energy Conservation Building Code (ECBC) is to provide minimum requirements for energy-efficient design and construction of buildings and their systems 8. DESK STUDY T-ZED Homes, Bangalore TZED (ZED stands for Zero Energy Development) is located at airport Whitefield Road, Bangalore. This five-acre site comprises of 95 homes built on the principles of sustainable resources. The great value of this experience lies in the demonstration, that modern comfort standards can still be met while associating with the principles of sustainable built environment, under the purview of the challenges posed by real estate market mechanisms and cost constraints. Every aspect of T Zed has been designed to conserve natural resources and to have minimal impact on the environment. In these homes, built-in, customized environment-friendly, zero electricity refrigerators, fully controlled air conditioning based 100 % on fresh air inputs, and built-in energy efficient lights are among the features that help to bring down energy consumption in the home while ensuring comfort levels and commanding a higher market value.

Cooperative housing societies in Delhi suffer from many problems. They have to be designed within the limits imposed by zoning regulations, which prescribe the total built area and the ground coverage. When these two are combined with fire regulations, they result in inflexible and uninteresting development. The alternative to group housing is plotted development, which starts and ends with a layout plan within which house owners build according to their needs and designs. The result is lack of architectural coherence and an excessive emphasis on individual buildings at the expense of overall environment. However, there are traditional examples of urban design that allow for individuality within an overall design framework like in the old city of Jaipur where buildings retain their identity without damaging the context.
