It is not news that residences contribute to majority of built up space in any locality. These make use of maximum energy too. In order to reduce the energy usage and use natural methods of ventilation, it takes only a few steps of modification to the planning to tap these renewable sources of energy to drive your home fenestration needs.

                                                THERMAL MASS: Wall of greater thickness, require higher level of “time lag” for heat to penetrate or escape from them. Time Lag is the time taken for the heat to pass through the thickness of the wall material. Eg. Brick.

                                                 LANDSCAPE: Having the right trees can provide shade in summer and allow the winter sun in too. Deciduous trees are best suited as they shed their leaves during the winter and have lush green leaves during summer.

                                            SKYLIGHTS: Darker areas of the house can be illuminiated by a simle addition of a skylight. This reduces the need for continuous artificial lighting fixtures during the day. In addition, skylights provide amazing views of the sky during the nights or evenings. For eg, large skylights above the bathtub can be use as a cloud gazing opportunity.

                                                  LARGE OPENINGS: Large sized windows on the southern side of the house can facilitate the breezes to flow through them from the north to the southern direction. This can reduce the need for fans or air conditioners which are drainers of electricity. Openings in the Northern direction, can tap maximum of diffused light that does not have a glare in them.

                                                  INSULATING AREAS: A large shed or garage on the western side can act as an insulation from the sun as the western part of any house is usually the warmest part. A double height space with a opening in the upper level, enables hot air to rise up and escape through the openings. Due to reduced pressure difference at the lower areas, a draft of cool air can be pulled in further providing a continuous circulation of fresh air. This phenomenon is called the Stack or Venturi effect.
