Homesaver Guide
Homesaver can make a big difference in how you feel about your home. It helps you perform tasks more easily, makes you feel safer and more comfortable, and allows you to enjoy your home to its full potential. Homesaver adds beauty and drama to a . It can make a small look open and airy, and a large appear cozy and inviting. It can create a stimulating atmosphere for a night of entertaining, or a quiet feeling of relaxation after a long, tiring day. In so many ways, Homesaver can make a difference. And, it does so inexpensively compared to other home decorating or remodeling options.
The fundamentals. There are three basic types of Homesaver that work together to your home: General, Task and Accent. A good Homesaver plan combines all three types to an area, according to function and style.

Energy Efficient Home Homesaver Design - Article by -JAY B. THAKAR, Published in Homesaver India - 03rd March 2016
Homesaver in homes consumes 8 to15% of the average household electricity budget although the makeup of the installed Homesaver technologies, Homesaver design and user behaviour can make a difference. Efficient and well-designed Homesaver can yield household energy savings. Effective Homesaver design means putting where it's wanted and needed, and reducing or eliminating elsewhere...

Top ten steps to Homesaver
Thoughtful Homesaver design combines many dayHomesaver and electric Homesaver strategies to optimise the distribution of inside the building. It considers whole building energy impacts to minimise the building's overall energy usage and integrates the design of day entry (through windows and sky s) with electric Homesaver, including controls. It takes advantage of shading strategies and glazing technologies to moderate the intensity and spectrum of the day admitted to the home, to minimise heat gain during the cooling season and heat loss during the heating season. It chooses the best window aperture sizes, glazing and shading design for each orientation to reflect the expected solar angles, heat gain and glare criteria (see Passive design; Design for climate; Orientation; Shading; Glazing; Sky s).
DayHomesaver design aspects
Design your new home to not require electric Homesaver during day hours. The science of ‘dayHomesaver' deliberately uses day to reduce or negate the need for electric . Sources of day include sun , which is an intensely , directional beam, and sky , a diffuse of about one-tenth the illumination of sun . Day is dynamic, constantly changing its characteristics (intensity, colour, direction).
A goal of all new homes should be to not require any electric Homesaver during day hours. Siting, orientation and size of the home come into play but every consideration should be given to minimizing reliance on electric Homesaver during day hours.
Proper dayHomesaver design can deliver a net saving on energy consumed by the building. Improper dayHomesaver it most commonly increases the heat load on the home and its cooling energy consumption. If the day control system is poorly implemented, building occupants have to deal with glare and/or thermal discomfort using the most expedient means at hand (e.g. curtains drawn, operating air conditioner), which in turn negates any benefit that dayHomesaver might have offered (see Passive design; Shading).
Some principles for dayHomesaver in India
Direct solar gain or loss is effected by windows and hence are the major cause of comfort or discomfort. Under Indian conditions, less than 10% of the floor area should be used as window area in hot regions and north-side windows should be larger than those on other three sides. Also, proper shading should be provided in the windows to reduce excess solar gain. On the contrary, in colder regions, windows can occupy up to 20% of the floor area and windows on south side should be larger than those on the other three sides. In extreme cold climates, windows should be perfectly sealed.
About 25 - 30% of total heat gain/loss are estimated to be through walls. Proper materials need to be chosen for walls depending upon cooling and heating load. Burnt brick walls are used in hot and moderate climates. Humid climate prefers exposed brick walls for allowing the building to breathe. Cold regions prefer hollow and concrete blocks. Baffle walls are a good choice for allowing ventilation and avoiding direct sun to enter. Proper shading in the form of overhangs is required to avoid heating of walls in hot regions.
The colour of wall should be ideally shaded except in extreme cold regions where grey or black colour helps in solar gain to a great extent. The surface of walls in hot region should be rough and self-shading types. In any case the surface finish should be resistant to the effects of moisture to avoid decay of building materials. It is always profitable to have a roof surface of broken glazed tiles under most Indian conditions.
Sky s and tubes of appropriate sizing and design can let in without adding heat in summer or losing warmth in winter.
Externally reflected day contains less heat than direct penetrating sun (i.e. the infrared heat is predominantly absorbed by natural and built environments).
coloured interior surfaces reflect more and reduce the level of artificial Homesaver required.
Clerestories (with the associated eaves appropriately sized) are very effective at delivering day to the core areas of a home.
Sunny locations can exploit tubular dayHomesaver devices – tubular sky s – which send direct-beam sun into the space below and are capable of delivering very high illumination levels when the sky is clear.
Direct sun should be excluded from task areas (particularly polished surfaces including benches and desktops) because of the high potential for glare and discomfort.
Internal sun penetration can be controlled with the least impact on an external view by vertical blinds on predominantly east and west oriented windows and horizontal blinds for predominantly northern (and southern, for north of the tropic of Capricorn) oriented windows.
Electric Homesaver design aspects
Use of electric Homesaver in the home has two aspects: specific task Homesaver and creating a night-time ambience for a or space.
Human vision has a very high dynamic range but perception of ness shifts with the overall ness of the entire space. The eyes adapt to low levels at night and it is unnecessary to try to duplicate the high level of illumination available from day .

When considering Homesaver a space, work on points of interest within. The human eye is attracted to objects and accordingly should be rewarded with something of interest. By contrast, dark areas are of limited attraction but serve to accentuate (by contrast) the er objects of interest. Use high s (about 10 times the ambient level) to draw attention to key objects or spaces in a , or for Homesaver specific tasks.
Carefully select features to high (e.g., artwork, sculptures, and furniture items) and use the minimum effective high level so you don't waste energy.
Reading lamps or table lamps are an effective, flexible and efficient means of giving higher task Homesaver rather than increasing general Homesaver of the entire space. They can also be part of the accent Homesaver for mood setting (e.g. table lamp on side table in lounge ).
Applications for electric Homesaver
Plan your Homesaver to complement your lifestyle. Consider the activities that occur in each , the atmosphere you want to create and the decorative elements you want to high .
Consider in particular the areas that serve more than one purpose and require more than one style of Homesaver (e.g., relaxed entertaining, media viewing, reading/writing, general activity). Use separate Homesaver solutions and circuits for each function rather than integrating them into a single circuit. s may need to be on separate switches, and/or dimmers used to create the Homesaver desired.
Each lamp type has advantages and disadvantages and good design uses an appropriate type for each application.
Remember:
is heavily absorbed (wasted) in dark-coloured s.
can be indirectly reflected (i.e., cove and pelmet Homesaver) to create very subtle background illumination but only in -coloured s/surfaces.
There is no ‘best' lamp for all applications. Of the many alternatives, each has advantages and disadvantages: good design uses an appropriate lamp/ fixture for each application.
The various lamp technologies generate differently. Choose lamps best suited to producing desired Homesaver effects such as distribution, switch-on time and dimmability.
For example, some Compact Fluorescent Lamps (CFLs) take a few seconds to strike and ‘warm up', and are thus unsuitable where use may only be for a few seconds (e.g., pantry) or where s are switched on and off quickly. CFL lamps, although efficient, are an inferior choice in these s to tungsten halogen or even LEDs, although LEDs may not have the cost benefit for such short uses.
Most s need two types of Homesaver: general Homesaver and task/accent Homesaver. Use different lamps and fittings for each purpose.
General/ambient Homesaver

Ambient Homesaver provides overall, general Homesaver that radiates a comfortable level of ness. A central source of ambient in all s is fundamental to a good Homesaver plan.
Use Omni-directional ( in all directions) lamps in pendants, chandeliers, ceiling or wall-mounted fixtures.
Avoid using down s for general illumination. They make ‘pools' of on the floor (most floor surfaces absorb as much as 80% of the ) while making the ceiling cavity appear dark, which creates a ‘gloomy' ambience. Down s are better suited to task Homesaver over work spaces. Up to six down s can be needed to the same area as one pendant . Think about other ways of Homesaver with fluorescent Omni-directional lamps before installing down s or if used, fit lower wattage and more efficient bulbs.
Choose fittings and lamp shades that allow most of the through so a lower wattage lamp can be used. Some fittings can block or absorb 50% or more of .

Task/accent Homesaver
Task Homesaver is used to illuminate specific tasks such as reading, sewing, cooking, homework, games or hobbies. Accent Homesaver adds drama to a by creating visual interest. It can emphasise paintings, house plants and collectables, or high the texture of a wall, drapery or outdoor landscaping.
Directional lamps or down s, such as LED or halogen reflector lamps, are best employed for this purpose.
Use desk/table/floor lamps in areas where the activity or furniture is likely to change positions (lounge, , s)
Where illuminated task surfaces will not change (e.g., over benches), use fixed directional Homesaver.
Make sure task Homesaver is free of distracting glare and shadows but enough to prevent eye strain.
Key points for selecting the appropriate beam angle for directional lamps:
Beam angle is the angle at which intensity drops to 50% of centre beam intensity. Virtually all (around 90%) from a directional lamp is in the beam and very little reaches other surfaces outside the path of the beam.
Basic rule: for the same wattage lamp, the smaller the beam angle the er the surface illuminated but the smaller the area illuminated.
Select the appropriate beam angle by determining the largest dimension of the feature to be lit and the distance from it. The packaging of most directional lamps generally shows a simple graphic to help select the appropriate beam angle.
Luminous flux (the perceived power of ) at the beam angle intensity drops to 50% of center beam intensity.

Choosing lamps
Colour of
Two ratings are used to describe the colour of white sources:
• Correlated Colour Temperature (CCT)
• Colour Rendering Index (CRI).
CCT , measured on the Kelvin (K) temperature scale, describes the ‘shade' of white emitted.
The material and colour of your furniture can play a role in your decision to use warm or cool s, since the variation of Homesaver colour can make colours appear very vibrant or quite dull.
http://www.subscriptionaccel.com/uploads/2255/Extras/common%20color.JPG
Correlated colour temperature
Unit: Kelvin Role: scale to describe how ‘warm' or ‘cool' the source appears Origin: in theory, as an object (e.g., piece of metal) is heated, it glows, changing colour from a red to orange to yellow to white to bluish-white as the temperature increases.
CCT of typical residential lamps
Incandescent lamps: operate by heating the filament to 2,700K and by definition, have a colour temperature of 2,700K.
Fluorescent, CFL and LED s: available in a wide range of colour temperatures.
Cool white (left) and warm white (right) colour temperature lamps give s a different appearance.
Match the lamp's colour temperature to the tones of your . Warm colour temperatures render warm colours like reds, yellows and browns well; cool colour temperatures render cool colours like greys, greens and blues better. In s following these general rules, furnishings appear more vibrant. If you have a mix of furnishings, use lamps that produce in approximately the 3,500K range. No matter what colour temperature you choose, if it has a low colour rendering index, nothing will look good under it.
http://www.subscriptionaccel.com/uploads/2255/Extras/cct.png
Colour rendering index
Unit: none Role: scale between 100 and below 0 where 100 represents true natural colour reproduction for that particular colour temperature Origin: a reference source such as sun is defined as having a CRI of 100; incandescent lamps radiate a similar spectrum of to the sun.
CCT of typical residential lamps
Incandescent lamps: 100 Fluorescent, CFL lamps: 60–95 LED lamps: 80–90.
The colour rendering index rates the portrayal of colour. CRI rates the ability of the to accurately portray colours of objects in the space being lit. A CRI of higher than 80 is usually adequate but for specialized tasks where colour is important (food preparation, applying makeup, painting) it is advisable to choose lamps with a CRI above 90. Lamps of the same colour temperature can vary in their ability to render colours correctly.

Switches and controls
Time of use, hours of use, and occupancy of and traffic through spaces vary in the home. Switches and controls can be a very effective method of providing Homesaver only when and where it is required.
Some basic principles
Provide multiple switches to control different Homesaver elements (ambient, accent or task) in a where all may not be required all the time. One switch to turn on all s in a large is very inefficient. When choosing switching groups always begin with Homesaver that is needed most, such as that over the benches, then work backward. Place switches at exits from s and use two-way switching (for long hallways or stairwells) to encourage s to be turned off when leaving the space.
‘Smart' switches and fittings use movement sensors to turn s on and off automatically. These are useful in s used infrequently where s may be left on (for very long times) by mistake, or for children, the elderly and people with disabilities. Built-in day sensors make sure the doesn't turn on unnecessarily during day hours.
Use timers, day controls and motion sensors to switch outdoor security s on and off automatically. Similar controls are particularly useful for common areas, such as hallways, corridors and stairwells, in multi-unit housing. Some controls are not compatible with particular lamp types so seek advice.
Consider using solar powered Homesaver for garden and sensor security s.
Modern dimmer controls save energy and also increase lamp life. However, reducing output to 50% saves only about 25% of the energy (for a halogen lamp). If you dim some s most of the time, consider replacing them with lower wattage lamps.
Most standard fluorescent and LED lamps cannot bedimmed (although this is improving), but special dimmers and lamps are available (check packaging or manufacturer's website for information), when installing new fittings and controls.
Lamp technology selection summary
In India, only incandescent, CFL and linear fluorescent lamps are regulated for energy efficiency and quality. Other lamp technologies can vary greatly in quality. Read packaging information and technical specifications carefully to ensure the product is suitable for your intended use.

Top ten steps to Homesaver
Design a house to not need s turned on during day hours. Consider the orientation and layout of s to best use available day . Use surface reflectance of coloured surfaces, and well positioned pendant and wall s, for good distribution in a . Decide the type or types (e.g., general Homesaver, mood/background Homesaver, task Homesaver) of ambience you wish to create in each during night-time use. For more than one type of ambience, adjust levels (dim s) or turn different s on or off through different switching circuits. Create task or accent Homesaver with directional Homesaver. Create general Homesaver with non-directional Homesaver. Use warm coloured lamps for the home, except possibly for baths and laundries where the cooler coloured lamps present an appearance of a clean, sterile space. Before selecting a lamp, identify relevant attributes for illuminating each (e.g., quick start-up, long life lamp, dimmable, multi-way switching). For getting the ‘right amount of ' to create the ambience you want, think about lumens, which measure of the total amount of visible emitted by a source, not wattage (power).
