CEPT University, Ahmedabad - Net Zero Energy BuildingDanfoss India
CEPT (University focuses on understanding, designing, planning, constructing and managing human habitats. Centre for Advanced Research in Building Science and Energy (CARBSE) at CEPT University was established with the aim of providing impetus for research in energy efficiency in built environment and energy resource management at large. CEPT University was one of the top 10 shortlisted finalists for ACREX Hall of Fame powered by Danfoss.
Sustainable Practices
• Insulated wall, roof and floor to reduce heat gain
• Radiant panels and DOAS used for conditioning basement spaces
• Demand controlled fresh air supply based on CO2 sensor
• Combination of radiant panels and VRF for space conditioning for first and second floor
• LED fixtures for ambient and dimmable task lights
• Renewable (PV) Contribution – 34,461 kWh (for 10.5 months)
amount of energy used is equal to amount of renewable energy created on the site
reduce carbon emissions & reduce dependence on fossil fuels
Buildings that produce a surplus of energy over the year are called “Energy Surplus Buildings”
During the last 20 years more than 200 reputable projects claiming net zero energy balance have been realized all over the world.
NZEB buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. Traditional buildings consume 40% of the total fossil fuel energy in all over the world and are significant contributors of greenhouse gases.

Energy Based Analysis of a Thermal Power Station for Energy Efficiency Improv...IJMER
Despite of growth of renewable energy stations installations like wind, solar, Tidal power, the energy for the world depends heavily on fossil fuels for electricity generation. It is also expected to continue the dependence on fossil fuels for next few decades. Therefore, given the continued reliance on the fossil fuels for some time, it is important to note these plants must reduce their environmental impact by operating fossil fuels more efficiently. Two types of analysis namely, energy and exergy analysis can be developed for the system. Energy analysis based on first law of thermodynamics cannot be applied as it cannot justify the real useful energy loss because it does not differentiate between the quality and quantity of energy within the system. Whereas, exergy analysis will characterize the work potential of a system based on the second law of thermodynamics and the maximum work that can be obtained from the system when its state is brought to the reference or dead state (standard atmospheric conditions).This technical paper presents the results of exergy and energy analysis carried out on 62 MW coal-based thermal power plant to evaluate the performance. The performance of the plant was estimated by a component-wise modeling followed by a system simulation. A parametric study is conducted for the thermal plant under various operating conditions, including different operating condenser pressures, temperatures and flow rates of cooling water across the condenser etc, in order to determine which parameter that maximizes plant performance. Energy loss distribution to find out the amount and source of irreversibilities generated in boiler and turbine in a plant so that any process in the system having largest energy destruction can be identified and that helps the designer to re design the system components.

Solar air heater from the major component of solar energy utilization system which absorbs the incoming solar radiations , converting it into thermal energy at the absorbing surface , in transferring the energy to a fluid flowing collector. The efficiency of flat plate solar air heater has been found to be low convective heat transfer coefficient between the absorber plate and the flowing air which increases the absorber plate temperature , leading to high heat losses to the environment resulting in low thermal efficiency of such collectors.
Artificial roughness in the form of repeated ribs the most effective and economic way of improving the thermal performance of solar air heater.
From the Literature review we conclude that the Multi V ribs with gap gave highest enhancement in nusselt number , however there was a very high enhancement in friction factor also.
All the research work is done on Single pass SAH so we worked upon the Double pass SAH.
From Literature review we also conclude that by providing turbulence ( Ribs ) the SAH is more efficient than Flat plate SAH.
The major objective of this work is to find out the ways to improve effectiveness of SAH by integration of Artificial Roughness Solar Air Heater By Using Perforated Multi V Ribs with Double Pass Parallel Flow.
The second objective is to come out with new shape and geometry to enhance effectiveness of SAH and compare it with other existing geometries and find out gaps and limitations of that shape.
Equations Used are DITTUS BOELTER and MODIFIED BLASSIUS EQUATION.
Parameters Used are Raynolds Number , Nusselt number , Friction factor and we have to find out variation in between these parameters with respect to other by plotting graphs.
