Energy efficiency has always been an integral part of lighting design, but it has rapidly become one of the top concerns that lighting designers and electrical engineers deal as lighting loads accounts about 40% of the total load in any commercial building. The load used by the lighting system can Read more…
Building Energy Simulation Energy simulation is a computer based analytical tool that helps to evaluate the energy performance of building. This helps to do modifications in the in the designs of the building before its construction. Use of energy simulation also becomes important to show compliance with the ASHRAE in Read more…
Recently Environmental protection organizations expressed highly concern about the abrupt increase in carbon emissions across the world from the buildings. Global concern about the environment has insisted people to adopt Building that are more eco-friendly even more than the Green Buildings. Now what a Net- zero Energy building really is? Read more…
It is important to take care of various design aspects to make your building green. There are various considerations to make your building sustainable/green. In this article we are highlighting 3 main considerations which has to be adopted by architects and engineers while designing a green building. Those considerations are Read more…
Central Electricity Authority (Technical Standards for Connectivity of the Distributed Generation Resources) Regulations 2013 IEEE 1547 – Standard for Interconnecting Distributed Resources with Electric Power System, 2003 Central Electricity Authority (Measures Relating to Safety and Electricity Supply) Regulations, 2010 Central Electricity Authority (Technical Standards for Connectivity to the grid) Regulations Read more…
After HVAC system, lighting system is the next largest energy consumption system in any commercial building. Usually lighting consumption is expressed in the form of lighting power density. The lighting power density (LPD) can be defined as the lighting load in watts/sq ft (or watts/square meter). Particularly, for a commercial Read more…
The recent report released by IRENA (International Renewable Energy Agency) highlights that global electricity generated from solar photovoltaics will grow as much as 13% by 2030. The solar industry’s growth will be primarily driven by significant cost reductions among various countries. The IRENA report named “Letting the light” examines PV Read more…
It is fact that the adding insulation reduces the heat gain. However, there is a increment in the cost to do so. But the cost of amount of energy that can be saved by adding insulation is comparatively higher than the cost of insulation. Therefore, addition of insulation is much Read more…
There are many PV module suppliers in the market, and if we assess the different characteristics of the PV module, it becomes challenging to compare the different suppliers and do the apple to apple comparison. Obviously, there are technical as well as commercial considerations while selecting the solar PV modules, however Read more…
PV modules in case of large-scale power plants are selected based on the integration of modules, voltage and current rating with the inverter voltage and current rating. Typically for a grid connected plant the inverters operate in the voltage range of 450-750 volts and accordingly the modules are selected to Read more…
