An introduction to daylight products
Daylights are products that allow sunlight into the building without any heat. The daylights are basically of two types, one is tubular type popularly known as lightpipe or solar pipe and the other is prismatic daylights usually known as Norikool daylights. Lightpipes Lightpipes The lightpipes transmit the sunlight collected outside the building into it through a tubular arrangement. The lightpipe consists of three major parts listed below.Light CollectorReflective SystemLight Diffuser LIGHT COLLECTORThe light collector collects sunlight from all directions and delivers light effectively through out the day even at low sun…

Case Study on heat reduction by Skyshade Norikool daylights in factories
Skyshade Norikool Daylight eliminates the transfer of heat into the buildings in great extent. To understand the impact of Norikool in the the transfer of the heat, the following two case studies are helpful. Methodology The site temperature is measured using a fluke thermal imaging camera. In case study one, the difference in temperature between conventional skylight and skyshade norikool double glaze daylight is measured. In case study two, heat transmit at skyshade norikool double glaze daylights and the non insulated roof is measured and the difference in noted. CASE…

Comparison between Roof skylights and Daylighting technologies
The use of daylights i.e., bringing sunlight in to buildings without any heat has become prevalent these days. These daylights are replacing the conventional skylights or strip lights. The daylights have many advantages over the conventional skylights. The factors that show that daylights are better than traditional skylights are listed below. Skylight to floor ratio Material Construction Spread of light Roof area usage Life & Maintenance required Heat transfer Automation Product Technologies Skylight to floor ratio (SFR) The ratio of skylight area to the floor area is called the Skylight…

How to choose the right ceiling fan for your workplace
Ceiling fans are widely used in workplaces. Even though many work places have centralized or other type of air conditioners, ceiling fans are still used for ventilation purposes. The selection of the ceiling fans is fundamentally based on the following factors Room size Energy consumption. Payback Period Room Size Based on the room size, the fans can be selected by the blade span. Blade span is calculated by multiplying the length from the center of the fan to blade by two. Blade Span = Distance from the center of the…

Solar Water Heaters – An introduction
Solar Water Heaters as the name suggests are used to heat water through solar energy. The solar water heater taps the sun’s heat and uses it to heat the water. Working Principle Solar water heaters works on the principle of thermosiphon. Cold water usually have higher density and stays at the bottom of any container. When the water is heated, the temperature rises and the density becomes lesser. As the density becomes lesser, the hot water moves to the top of the container. This is the principle of thermosiphon. The…

Components of a Solar Photo Voltaic Panel
Solar Photo Voltaic Panel is the key part of a solar photo voltaic power generation system. This articles briefs on the various components of a solar photo voltaic panel. The solar photo voltaic panels are kept outside facing the sunlight. The PV panel converts the sunlight in to DC electricity. The solar photo voltaic panel is generally of three types 1. Poly Crystalline solar panel 2. Mono Crystalline solar panel and 3. Thin Film panel. The crystalline panels are made of crystalline silicon while the thin film panels are made…
