PASSIVE DESIGN JUHI SRIVASTAVA | NIRBHAY SINGH

Passive Design regards the particular way to construct a building using the natural movement of heat and air, passive solar gain and cooling in order to maintain a good internal comfort.

SHADINGÂ

Thermal mass describes the ability of building materials to store heat. Thermal mass is used to store heat from the sun during the day and re-release it when required.

THERMAL MASS

Glazed windows and doors bring in light and fresh air and offer views that connect interior living spaces with the outdoors. However, they can be a major source of unwanted heat gain in summer and heat loss in winter.

WINDOWS & GLAZING

Optimal positioning of a home on its site can have a significant impact on its thermal performance It takes account of summer and winter variations in the sun’s path as well as the direction and type of winds.

ORIENTATION

Areas that are used for relatively short periods of time such as bathrooms, laundries and garages are best positioned on the west to provide a buffer against the extreme summer heat.

LAYOUT

High performance roof, walls, doors and windows provide superior insulation when combined with other insulation materials. This reduces the amount of artificial heating and cooling needed to maintain thermal comfort

INSULATION

Shading of a building reduces summer temperatures, improves comfort and saves energy.Effective shading which can include eaves, window awnings, shutters, pergolas and plantings can block up to 90% of this heat.

SHADING

NOAIN CITY HALL ARCHITECT - Zon-e Architects LOCATION - Navarra, Spain PROJECT YEAR - 2009

The project has been subject to an energy rating, resulting in a 60% saving.

The center of the building is an empty space, that introduces northern light to all the circulation spaces.

The facades are composed of a translucent double skin.

The creepers are deciduous, and they work as a seasonal filter

The distribution of cold and heat inside the building is done through a radiant floor. It consists of a network of micro tubes embedded in the floor, turning all the surface in a large heating and cooling system. A small gas boiler placed on the top of the building improves system performance in those periods when it is necessary to reach required temperatures instantaneously.

PASSIVE HOUSE BRUCK ARCHITECTS - Peter Ruge LOCATION - Â Zhejiang, China AREA - 2200.0 sqm PROJECT YEAR - 2014

It is the first housing of it’s kind to be realized in the countries damp, warm, southern climate with 95% energy saving.

Triple glazed window units have been specifically used in all private rooms and common areas.

Sun shading elements protect the glass facade in the warmer half of the year. Â Protection from intense sunlight through a screen of colored terracotta rods.

TERI RETREAT BUILDING ARCHITECTS - Sanjay Prakash LOCATION - Gurgaon, India AREA - 365000 sqm PROJECT YEAR - 1974

The entire complex is southfacing, with deciduous trees all around it.

The roof is insulated with vermiculite concrete topped with China mosaic.

Walls are insulated with 40-mm thick expanded polystyrene insulations.

Basement is made for ground storage and thereby stabilize internal temperature.

Less than 10 KWs of energy is used to light the entire complex.
