Aspire To Own A Green Home?

Setting up Solar panels help to reduce electricity costs because it helps you to produce your own electricity and can be cost effective in the long run. Solar Panels should face the South to an inclination of 15 degree.

Going Green and building Zero energy buildings is the way forward. There is no single standard about what makes a home green. However, as a general principle, it is easier for a home to be truly “green” if it is designed keeping the following factors in mind when it is built:

Here are a few important points to be kept in mind while making a green home:

Building Envelope :

Use of locally available and manufactured Autoclaved Aerated Concrete (AAC) bricks, fly ash bricks to reduce dead load and embodied energy. The AAC bricks acts as insulators and do not require use of plastering which means comfort at minimal costs and saving of time.

Site Orientation of a Green-Sustainable Home

Managing the natural elements mainly the sun and wind features helps to evolve a building that has good orientation features. The north-south orientation minimizes direct sunlight during the summer which reduces cooling demands while maximizing sunlight during the winter. If not, then there can be east & west facing windows, which should be either double glazed or should have a projection or deep balcony covering the window sufficiently.

Placement of Fenestration

Maximum number of windows should be placed on the north side of the façade to bring in natural light & reduce glare. Double glazing with high performance glass for insulation on west façade helps in saving on air conditioning, keeping house cooler in summers, warmer in winters and providing good acoustics. Also designing pergolas, louvers, jaalis help to reduce heat gain and promote ventilation.

Rain Water Harvesting

Rain water harvesting can be done in apartments by setting up splash back or use rain saucer to collect rainwater in a separate rain water harvesting water tanks. This water is devoided of its impurities and then sedimented & pumped up and used for external purposes such as washing cars etc.

Waste Management-

Sewage treatment plant (STP) plays a vital role in the process of removing the contaminants from sewage to produce liquid and solid (sludge) suitable for discharge to the environment or for reuse. Waste water is produced from toilets, baths, showers, kitchens and then collected in catchment basins and treated in phytorid bed.

Use of Sustainable Building Materials

Use of durable, reusable or recyclable materials like Bamboo, jute ,wood can help in keeping the environment green. Flyash bricks and A.A.C blocks must be used for the walls as both of these are natural insulators of heat and are produced from the industrial waste.Bricks, wooden doors frames &shutters removed from building after demolition of old building , can also be recycled and reused.

Energy efficiency

It is one of the most important factors in all green building. All lights should be replaced with LEDs and all electrical appliances should be 5 star rated appliances. Setting up Solar panels help to reduce electricity costs because it helps you to produce your own electricity and can be cost effective in the long run. Solar Panels should face the South to an inclination of 15 degree.

Terrace - Proper insulation of roof slab also plays a very important role in improving the energy efficiency of a home. White heat reflective tiles are a good option, to reduce heat gain on the roof. Roof plantation with soil (terrace garden) absorbs heat, acting as an insulator, reducing upto 7 degrees temperature.

Water Bodies – Water which is circulating is good for absorbing suspended particulate matter and helps in reducing pollution. Use of fountains, waterfalls, circulating water can help in reducing indoor temperature, beside adding to ambience and air quality.
