The fresh air, in turn, provides oxygen for inhalation, alleviate odors and regulate temperatures. Advantages of natural ventilation systems include increased effectiveness at eliminating humidity of the incoming air and reduced energy consumption.
A house needs to be well ventilated for the comfort of its residents and to help care for the building. A whole house ventilation system is more convenient than simply opening a window or relying on draughts, because it allows you to control the flow of fresh air and does not present a security risk.
After Surgery. A ventilator is necessary when the patient is unable to breathe well enough to provide oxygen to the brain and body. Patients who smoke experience higher rates of requiring a ventilator longer after surgery is completed.
Importance of lighting in interior design:
Good lighting assures a warm, inviting and functional atmosphere in your home. Hence selection of proper lighting is the key element in interior design as it enhances everything in a room – from the furniture, flooring, fittings to the finishes and textures.Common health effects associated with poor lighting include:
- Headache and eyestrain.
- Neck, back, and shoulder strain (when straining to see items because of poor lighting)
- Falling, tripping, slipping.
- Dropping materials or tools.
- Depression (in the case of insufficient or gloomy lighting)
Cross ventilation helps draw cool air in and push stale or stagnant, hot air out of any building. This form of ventilation drives air from openings at one side of a building through to the other. The success of cross ventilation depends on the tightness of the building envelope and the positioning of the openings.
Proper ventilation is vital to good indoor air quality. Ventilation brings in fresh air, helps circulate stagnant air, and removes particulates, allergens, and pollutants, increasing the daily productivity and health of your valuable workers.
It influences air quality and energy efficiency, and proper ventilation controls odors, dilutes gases (such as carbon dioxide), and inhibits the spread of respiratory diseases. Ventilation air is critical in educational facilities.
Ventilation systems can be categorized as one of four types: exhaust, supply, balanced, and heat-recovery. The right ventilation system for a particular house depends upon the climate and the needs of the structure.
Well, poor ventilation can have serious consequences. It can make our homes “sick”, with condensation and mould damaging the walls and fabric of our houses. But, more importantly, it can make the occupants sick. Mould, mildew and mites all thrive in environments that are high in humidity.
From the view point of comfortable living & working conditions, the good and efficient ventilation system should meet the following functional requirements:
- Rate of Supply of Fresh Air.
- Air movements or Air Changes.
- Temperature of Air.
- Humidity.
- Purity of Air.
For Natural Light
So, if a room is 10 feet wide x 12 feet long, then the room area would be 120 square feet and the minimum size of the window in that room would have to be12 square feet. A three foot by four foot window would provide 12 square feet of natural light to the room – again, the required minimum.Natural lighting, also known as daylighting, is a technique that efficiently brings natural light into your home using exterior glazing (windows, skylights, etc.), thereby reducing artificial lighting requirements and saving energy.
Definition of ventilation. 1 : the act or process of ventilating. 2a : circulation of air a room with good ventilation. b(1) : the circulation and exchange of gases in the lungs or gills that is basic to respiration.
For Natural Light
1) A given room must have a window or glass door that is sized to equal at least ten percent of the floor area of the room. So, if a room is 10 feet wide x 12 feet long, then the room area would be 120 square feet and the minimum size of the window in that room would have to be12 square feet.Natural lighting will reduce the production of harmful bacteria and organisms that can grow in any house. Sunlight improves circulation. Natural sun increases red blood cells. Sunlight boosts your immune system.
habitable room - 5,000 mm² equivalent area. kitchen, utility, bathroom (with or without WC) - 2,500 mm² equivalent area.
Ways to Increase Natural Light in Your Home
- Add More Mirrors and Shiny Objects.
- Choose the Right Colour Palette.
- Bring in New Furniture and Accessories.
- Install Larger Windows or Doors.
- Replace Wall Space with Glass Blocks.
- Wash the Windows.
- Lighter Window Treatments.
- Add Skylights.
The rule of thumb is that you need at least 1 CFM per square foot of room area. To determine the square footage of your bathroom, multiply the length times the width. For example, if your bathroom is 6 feet wide and 9 feet long, its square footage is 54. Therefore, it should have a fan rated for at least 54 ?CFM.
Proper ventilation prevents air pollutants from affecting the health of you and your family. Not only that, having airflow in your home can get rid of any unwanted smells, such as from cooking or pets. One of the reasons ventilation is so important is because it controls how much moisture is lingering in your home.
Good lighting is vital to good health. Both having exposure to natural light and having good quality artificial lights are necessary. The centre should use as much natural light as possible with skylights, large windows and outside play time, but always minimise the exposure to the sun's rays.
Quality air and adequate light contribute to the prevention of certain diseases, such as tuberculosis, and also get rid of carbon dioxide and bad odours.
