Net Metering and Distributed Generation Systems

India has an ambitious Solar Energy capacity addition program of adding 100 GW by the year 2022. Out of above 40 GW is expected to be added through Roof Top Solar. Addition of 40 GW as part of Roof Top Solar in next 5-6 years is quite ambitious. Various states have announced their state specific policies for implementation of Roof Top solar programs. Net Metering policies are entwined with Roof Top solar programs. Though quite a few states have announced their programs but real work on the ground has yet to pickup. In US and some other EU countries where sunshine is abundantly available, there has been a never ending debate on practical Net Metering policies and applicable  energy tariff regime. There is a group which advocates retail tariffs while another group supports the DG to be billed as per the Utility Generation charges.

Energy Efficiency and Smart Cities

Smart Cities have been defined in many ways. The urban urban migration leading to vertical growth in city landscape is a necessity in any smart city. Smart cities lays a lot of emphasis on Green Building and Energy Efficiency. The concept paper on Smart Cities neatly sums up the energy concerns “Good areas to focus energy efficiency measures would be the building material used, the transport system, sewerage and water supply systems, street lighting, air-conditioning systems and energy consumption in buildings.”

Building Management System Green Buildings

Building Management System (BMS) is an intelligent management system involving integration of software and hardware with the objective to manage varied electrical and mechanical systems of the Green buildings. BMS manages heating, ventilation, air-conditioning (HVAC), access control, security, lifts, transformers, DG sets, LT switchgears, water pumps, blowers and lighting requirement of any building. the systems are so designed and networked that one can get detailed drill down information about various equipment working in the building along withe their energy usages.

Green Apartment

People are gradually moving towards living in apartments. There are definite advantages of  a life lived in apartments. When we think of building smart cities, the very first thought that we have is to build clusters of apartments where people can be gradually shifted. Apartment living definitely creates lesser carbon footprint than living in independent houses. Green apartment is nothing but an apartment either in a Green Building or an apartment where one has adopted a number of steps which are helping in resource conservation and energy savings. Our fathers have lived all their lives in independent houses and even, we have spent our childhood in those lovely houses with courtyards and lots of spaces in front and back.

Glass Facades in Modern Homes

Glass facades were earlier synonymous with the commercial structures and high rise office buildings but today their acceptance is steadily gaining in modern homes as well. Glass facades allow natural light and heat to enter into the structure and thus are an important facets of Green Buildings. However improper fitments and sealing gaps may also let in cold air. Today Glass Facades have become essential part of the Architectural design and based on the orientation of building and zoning pattern, there can be more than one type of glass glazing types being employed in buildings.

Orienting A Building

Designing a building, ideally is left to professionally qualified architects who are better placed to deal it with. But a learned house or a flat owner would always be benefitted if he or she is exposed to intricacies of building orientation. It is a known fact that buildings should generally be south facing. This not only helps in maximizing Day Lighting but also helps in reducing the glare and mitigating the overheating. A properly oriented building  throughout its life, will keep saving energy and contributing towards reducing the Carbon Foot Print.
