What are skylights?

Skylights

Historical architectural structures comprise of many types of skylights that were utilized to serve different objectives. However, at present, commercially - available skylights are largely classed as residential and commercial skylights. Domestic skylights designed to respond to domestic daylighting and heating requirements are frequently small in size and easy to install and maintain. Industrial skylights are frequently larger in size and require specialist expertise in installing. They are very pricey since extremely durable and waterproof materials are employed to lower the amount of maintenance. Both industrial and domestic skylights are further categorized as below according to their nature and use case.

Common skylight types


1. Fixed Skylights


They are often fixed to the roof and only allow sunlight to pass through. Ventilation is normally provided by these skylights. However, there are designs where ventilation is provided through small vents around the skylight structure. Another advantage of fixed skylights is that they provide a beautiful view of the sky.

 

2. Tubular Skylights



Reflective tubes are used in tubular skylights to transfer sunlight from the roof to the interior in tight spaces. These are perfect for hallways, pantries, foyers, etc. Modern fiber-optic skylight systems also come under this. When there is not enough space in the roof to place a massive skylight fixture, tubular skylights may be utilized to redirect sunlight to the interiors efficiently. Since reflectors are employed, the light shaft may be directed whenever desired. One of the drawbacks is that they do only provide lighting for the indoors but not the magnificent sky view offered by the vented and fixed skylights.

 

3. Ventilated Skylights



These are ideal for spaces like bedrooms, kitchens, baths, and laundry rooms where both illumination and ventilation are needed. The glazing of the skylight can be opened by tilting manually or by motor operation. These skylights also allow excess moisture and hot air to escape the space easily as they are commonly mounted on sloped roofs and attics (homestratosphere.com). Ventilated skylights are usually installed on highly pitched roofs and slightly slanted walls to minimize undesirable water leakages and dust collection

CoolPack for Refrigeration System Simulations

-
Image
1    Introduction to CoolPack Coolpack is a piece of software developed as a result of a research project, and is used by refrigeration engineers, technicians, students, etc. for energy optimization of refrigeration systems and to determine and compare the characteristics of different refrigerants available on the market. Unlike most of the other complex software with advanced graphical interfaces, CoolPack has a very simple, but much faster interface, which helps the users to carry out simple refrigeration system calculations with a minimum hardware requirement. The basic functionality of Coolpack can be described as follows. Calculation and comparison of the characteristics of different refrigerants. Property plots Thermodynamic and thermo-physical data Refrigerant properties Cycle analysis of single and multi-stage refrigeration cycles. Calculation and estimation of component sizes and power requirements for proposed refrigeration systems. Simulations to determine the pro...

(1/5) Impact of Skylights on Indoor Thermal Comfort and Energy Performance in a Non-Residential Building

My approach to the project This is my final year research project, which I worked on for more than 6 months. When I first started the project, I had no prior knowledge of thermal comfort, energy efficiency, or daylighting. During the initial stages of the research, I referred to several books and documentation to get a background knowledge of the topic, which was totally new to me. Most of the books and keywords were suggested to me by my supervisor, Prof. Rahula Attalage. I spent around two weeks reading the following books and reports to get familiar with basic theories and statutory requirements before starting work on the project. The Lighting Handbook 10th by Illuminating Engineers Society ASHRAE Handbook 2021 by ASHRAE Energy Efficient Building Code of Sri Lanka 2020 by SLSEA Figure 1 References I could learn numerous things about light, colors, visual light transmittance (VLT), etc. from the IES Lighting Handbook. From where light is produced to how the brain decodes light signa...

(2/5) Impact of Skylights on Indoor Thermal Comfort and Energy Performance in a Non-Residential Building

Collecting data for the project Figure 1 Arpico Super Center, Wattala. As stated earlier, the influence of skylights is highly dependent on the geographical location. Since the majority of the found information and conclusions are based on European and American countries, it was required to first examine an actual case from a local building prior to commencing more research. I could arrange a site visit by contacting a representative of the specific supermarket chain. After revealing the purpose of the study, the manager agreed to share some non-confidential information that was readily available.  * All information published here in my personal blog are freely available to anyone visiting the supermarket premises, and do not include any confidential information.       According to the management, the building is a 50,000 square-feet steel structure that was originally constructed as a storage facility for another organization and then acquired by Arpico in 2010...
