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.

Getting eco-friendly furniture is now easier than ever. Many more people are joining the green bandwagon and manufacturers are more than happy to tap into this market, while doing their bit for the environment. More and more people are opting for furniture made from reclaimed or recycled materials over wood and companies are happily going first to landfills and then to the banks.

After bamboo, recycled rubber, tin cans and cane, it is now time for Urban Wood. This is a relatively new entrant is the eco-friendly market but is catching quite fast. Urban wood furniture is made from wood that is salvaged around cities from tree falls, demolitions, and generally from the road side. Most of this furniture maintains its rough and ‘woody’ look and people seem to fall for it.

Another very unique and beautiful furniture or rather material option is found with Kirei USA. Kirei manufactures tiles and furniture material made from coconut, wheat, bamboo and kirei. Their tiles made for coconut bark and fiber area thing of beauty and their Wheatboards bamboo are excellent fire-resistant substitutes for wood. Their flagship Kirei board is lighter than wood but as durable and strong. Each of these materials also possess a texture and colour unique to the raw material that adds to its aesthetic appeal.

Quite frankly, it is not to much effort. Building technology has developed to a great extent since the passivhaus standard came into existence, and it is quite a bit easier to build a passive house now than it was 10 years ago. Most of the building material that you require are easily available. Passive houses are as comfortable to live in as any other homes and in fact are healthier and safer because of the building design.

Passive houses are more expensive to build than conventional homes because of the materials required between five and ten percent depending on size. However, over the long run, they have proven to be much cheaper. When you look at how much a conventional home costs in terms of heating, cooling, ventilating, electricity, and air conditioning – a passive house turns out to be a cheaper bargain.

Passive homes are not that uncommon either. Although it is difficult to find a completely passive house in the US – they’re common in the UK and across Europe. Closer to home, we have green homes that make use of some of the principles of passivhaus and add their own two bits to create an energy efficient green home. In Washington DC, we have architect and green builder Travis Price’s four story green home, just about 10 minutes from the White House. His house was featured on the Discovery channel’s World’s Greenest Homes – which, by the way, is a great show to see how much and how easily people can build green homes for themselves.

In order to be called as a ‘passive house’ a house must be built with certain standards in mind. These standards were created in Europe and hence apply to homes built in the European countries, but are used more or less in the same manner throughout the world:

1. The house should not consume more than 15kWh/m2 in a year for heating and cooling requirements.
2. Its total energy consumption in a year must not be more than 42kWh/m2

In the US, these standards change a little in the following manner:

A house to be called a passive house must be designed in such a way that it consumes 1 btu per square foot per heating degree day for space heating purposes, compared to traditional homes which use anywhere between 5 to 15 btu. Your contractor should be able to explain better what standards he expects to achieve.

Along with these there are also standards for insulation and air-tightness. The structure should not leak air any more than 0.6 times the volume of the house.

Standards of this type make most people think that achieving them will be rather expensive. However, in the long run, the energy consumption of a passive house is less than 25% than that of a normal house. Plus, the overall cost of building, installing and operating a regular house and a passive house are almost the same.

One can’t have a green home without actual greenery, can one? Open spaces, gardens and green areas are quite important in a house, not just for aesthetic appeal, but also because they help largely in maintaining fresh air indoors and keeping a steady temperature. If you’re few of the lucky homeowners whose homes have backyards then there’s nothing like it. We strongly suggest that you make use of the backyard to have your own compost pit or recycling plant. This is not difficult or messy. You’ll get helpful tips on how easily you can make compost at http://www.helpfulgardener.com/.

If you don’t have the advantage of a backyard, you can still do a lot. For starters, depending on the kind of walls you have, you could speak to your contractor about having a controlled ivy growing on the outside wall – but do this with a professional gardener’s advice only. If you have a terrace you could go about converting it into a terrace garden. It’s not too technical and it can keep your roof quite cool during summers.

Indoor plants are an excellent idea. A better idea is to create space outside windows by installing racks for keeping potted plants – They’re an excellent way of providing privacy. Many homeowners will also create indoor gardens – complete with waterfalls. Although these are expensive, you could speak to your contractor about the possibilities.
