We will all agree, that when it comes to home operating costs and maintenance, little else burns as large a hole in our pockets as heating and cooling. HVAC is one place where homes lose a lot of greenery – in terms of money, and in terms of the carbon footprint they add. Therefore, when we remodel homes, a lot of homeowners want to know how to restructure their HVAC systems, to make their homes (and their pockets) greener. Our answer to them – mini split systems.
Most homes run on centralized HVAC systems that use ducts and sometimes pipes to control temperatures indoors. While these systems are quite alright, they are not always feasible when you are attempting a remodel, especially if you are adding an extra floor or room space or making major design changes. Restructuring the entire duct and pipe system adds considerably to the cost. Mini split systems make it easy to manage indoor temperatures without any major construction or uprooting.
Mini split systems are also called ductless systems and are available for heating and air conditioning purposes. These systems come with three parts, which can be very simply explained as: one part which is mounted indoors to maintain air and temperature, one part outside which handles the condensing and compressing and a third part linking both parts with suction wires, electrical wires, drain and refrigerant tubing. This entire system can be fitted with minimal inconvenience and construction and works efficiently to heat/cool/condition as per your requirements.
The amazing thing about them is their efficiency. Bonneville Power administration just did a study that found that mini splits can be as high as 450 % efficient. For every $1.00 you spend you get $4.50 worth of heat. Nothing else on the market even comes close. Back that up with a supper insulated house and your heating bill will become a non issue.

There are also quite a few other things you should keep in mind when buying an installing LED lighting. Having the services of an experienced electrician at your disposal is very important, as is the knowledge of an interior designer who’s worked with LED lighting. Bear in mind the following points:
1. White LED lighting tends to emit a specific kind of white light, which is different from other kinds of white light. This causes certain colors to be seen differently. Thus, you might find that your interiors don’t look the way they were supposed upon installing LED lighting. It is thus important to get a ‘test’ done, or seek professional opinion to see if your interiors will go with white LED lighting. (However, newer LEDs seem to have conquered this drawback)
2. Many people will opt for LEDs specifically because of their aesthetic appeal. However knowing where to use which LED lighting is another important factor determining the aesthetics of the entire setup. An array of LED lightings could be used to illuminate an entire room, while miniature LEDs are great for lighting up stairways, corridors and external paths to the house. Many will also use miniature LEDs for lighting up kitchen closets from the inside. Using the wrong LEDs in the wrong place could lead to an interior disaster.
3. LEDs are the most expensive option – only in the beginning. Their initial high price is off-set by their efficiency (and thus the lower bills) and their lifetime. However, using them correctly is important to ensure this happens. Another aspect we suggest to all our customers who look at green building – When it comes to making eco-friendly decisions, we need to look at life time costs, rather than one-time costs. In this regard, LED seems to win the race.

There’s quite a fraction of people reading this series on LED lighting who will nod their heads in disagreement. You’ve probably heard from your friend’s that they are very-expensive, very-chic, or that LED installations go bonkers after a few months. The problem is not with LED. LED is one of the best lighting options for residences, when used correctly. An inexperienced electrician and incorrect buying decisions can do a lot of harm to the lighting of the house, to you and your pocket. Here’s what to bear in mind:
1. Buy the right type of LED for your requirements. There are low wattage LEDs, which will work on 1mA (very little) of electricity and there are also new High-Power, high wattage LED which will work on more than 1A (100+ mA) and produce over 1000 lumens. The low wattage ones are used singularly to create different effects, usually for decorative purposes. The high wattage ones are used in place of a light bulb, or used in an array to provide enough light for an entire room.
2. Both types of LED lighting have different requirements. Low wattage LEDs burn out very quickly if not used with the right kind of voltage. They require much less than what is available by default in homes. High wattage ones, on the other hand can work with what we have in homes but need adequate heat sinks that will absorb the extra heat they will produce. If heat sinks are damaged, the lighting will burn out in seconds.
3. LEDs are quite affected by ambient room temperature. Installing them into walls which are not properly ventilated or in rooms that tend to get warm affects their life expectancy, causing them to fade out faster.

The main reason we’ve included LED in our recommendations, is because they’re quite eco-friendly, compared to all other options. LED produce much more light per watt of electricity. To be precise they produce around 18-22 lumens per watt, much higher than the incandescent and fluorescent lamps. This means they use less power to produce more, which cumulatively adds up to a lot of energy savings. In fact, the US DOE estimates that if LED lighting were used on a large scale, it would convert to savings of $265 billion, reduce electricity demand for lighting purposes by 33% ; and avoid the set up of 40 power plants across the country.
Also, every time you turn on the lights, you’re contributing to CO2 emissions to the tune of 196 pounds per year, for every light bulb in your house. LED lamps bring this to just 63 pounds every year. LED lighting is also non-toxic, it does not contain mercury like fluorescent lamps and thus recycling them is less hazardous. A few other benefits:
• LEDs are extremely small and are available in different colours. This goes well when you try to get creative with lighting in your house.
• LEDs can be dimmed quite easily. Repeated on-off cycles don’t damage LEDs the way they damage other lights. Thus, using LEDs for Christmas lighting is the ideal option
• They’re shock resistant, not fragile like usual bulbs.

If you’ve been to a house that was recently done up (in a rather fashionable manner) – you might have found a lot of small whitish lights used in places where the conventional bulbs and CFLs used to be. These tiny things are LED (Light Emitting Diodes) a new entrant in the field of home lighting.
LED is a certain type of lighting device which is being increasing used in homes for many reasons. Largely, they are used more for decorative purposes, but their efficiency and long-life as compared to other fluorescent and incandescent lamps have led to LED using lamps to be used as the main source of light in a house.
The main factor working in LED’s favour is its efficiency. Unlike regular bulbs and fluorescent lights, which waste almost 90% of the energy they consume in the form of heat, LED release very little heat, using up most of the energy to produce light. Thus, its input/output ratio is quite high, and typically LED’s last about 20,000 to 35,000 light hours (compared to CFLs which last 15,000-20,000 hours and incandescent bulbs which last about 1000-2000 hours). This makes them an extremely cost-effective option, when compared to other forms of lighting.
To add to this, LED is available in a variety of colours and can be used very effectively for home decor. Also, LED is a point source of light. Which means if LED lighting is recessed into a wall, all the light it emits will go straight ahead into the room? When incandescent bulbs are recessed, only a fraction of the light will actually make it into the room.
