HVAC System: The equipment, distribution systems, and terminals that provide, either collectively or individually, the processes of heating, ventilating, or air conditioning to a building or portion of a building. Energy efficiency in a green building starts with a focus Read more
LEED: IEQ Prerequisite The Indoor Environmental Quality (EQ) category rewards decisions made by project teams about indoor air quality<br />and thermal, visual, and acoustic comfort. Green buildings with good indoor environmental quality protect the<br />health and comfort of building occupants. Read more
Green Buildings are not a choice anymore, it is becoming an integral part of the AEC industry. While we are aiming to build more green buildings each year, Government is also taking initiatives in providing infrastructure and incentives to promote Read more
Human body has the ability to adapt to environmental conditions and become accustomed to them over time. People accustomed to the variability of environmental parameters in non-air-conditioned buildings can live and work through a larger temperature range without experiencing thermal Read more
The impact of COVID-19 Has been significant in terms of demand loss and consecutive loss of revenue. The typical electricity demand loss due to COVID-19 has been estimated about 20% and the revenue loss has been estimated as 7.2% bye Read more
Manufacturers quote the efficiency of a PV System at STC conditions, i.e. at 1000 W/m2, however, due to parasitic resistances the efficiency is not constant as the intensity of solar irradiance changes. This is referred to as Irradiance loss Irradiation Read more
There are a series of important questions that come to mind when talking about sizing a PV system. 1.What is your monthly electrical usage? Your utility bills will show you how many kilowatt-hours of electricity you use on a monthly Read more
HVAC System: The equipment, distribution systems, and terminals that provide, either collectively or individually, the processes of heating, ventilating, or air conditioning to a building or portion of a building. Following are Space conditioning types as per Energy Conservation Building Read more
There are are a few basic factors to consider when designing any kind of system. Energy requirements2. Peak Sun Hours3. Site Location Evaluation4. Battery bank5. No. of Solar Panels Off-grid systems are designed to work alone and are sized so Read more
The off-Grid system relies heavily on better-abled storage systems. Battery: Stores energy by chemical reactions. Most stand-alone PV systems use lead-acid batteries. Flooded lead-acid battery: A battery that has a liquid electrolyte (fluid) and uses chemical reactions between lead and Read more
