Passive Design Techniques Presentation Bin Saram Designs | Delta Design & Engineering Pvt. Ltd

Passive Design Techniques Presentation Description

This presentation will explore the key principles of passive design, a sustainable approach to architecture that reduces energy consumption and enhances occupant comfort by utilizing natural resources such as sunlight, wind, and thermal mass. We will cover essential techniques including:

Orientation and Layout: Designing buildings to optimize sunlight and airflow.
Natural Ventilation: Utilizing windows, vents, and open spaces to circulate air.
Thermal Mass: Using materials that absorb and store heat to regulate indoor temperatures.
Insulation and Shading: Minimizing heat gain and loss with proper insulation and strategically placed shading devices.
Daylighting: Maximizing natural light to reduce reliance on artificial lighting.

2. ENERGY EFFICICENT TECHNIQUES Use energy efficiently some time energy efficiency to reduce the amount of energy required to provide and product services . For example Insulation of home to increase resistant To maintain temperature inside To minimize mechanical energy Bin Saram Designs Delta Design & Engineering Pvt. Ltd. Lahore

3. Features Openness and air movement Lightweight fabric - low thermal mass Large surface areas that maximize contact with external air Separation between buildings Extended roof overhang/eaves Use of light color on facades, roofing Window shading Bin Saram Designs Delta Design & Engineering Pvt.

7. BUILDING MATERIAL FOR WALL Cavity Wall - With insulation -Without insulation Cavity walls give better thermal insulation than solid walls. The space provided between two leaves of cavity reduce heat transmission into the building from outside U Value - Solid brick wall: 2 W/m²K. -Cavity wall with no insulation: 1.5 W/m²K. -Insulated wall: 0.18 W/m²K.

11. Cotton Insulation: made from recycled cotton materials like denim doesn't contain formaldehyde like traditional fiberglass insulation Materials used for insulation Paper foam: Made from recycled newspapers and cardboard then filled with chemical foam. Straw Bales: naturally provide very high levels of insulation for a hot or cold climate Green Crete Recycled Plastic

14. LOW-E GLASS This glass varies from normal clear glass in that one side of the glass has a special metal Coating, technically known as a low emissitivity , or Low E. coating. of heat or cold Characteristics of low-e glass : Low-e Glass stop the ultraviolet rays. It enhance the visible Light to get in the space. Infrared light or heat energy, is transmitted as heat into a building, Low-e Glass stop the heat and keep the space comfortable.

16. FOR ROOF GREEN ROOF A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. Bin Saram Designs Delta Design & Engineering Pvt. Ltd. Lahore

20. REFLECTIVE ROOF A reflective roof coating is applied to roofs to help reflect more sunlight from the surface, thus reducing the amount of heat absorbed by the structure. Bin Saram Designs Delta Design & Engineering Pvt. Ltd. Lahore

22. INSULATED ROOF Roof insulation material is made from the two different layers of aluminum foils sandwiched with the inner layer of foam, plastic bubble sheet or fiber glass . It reflects around 97% of radiant heat from the roof surface and prevent energy and higher temperature penetrating inside.

23. SHADING DEVICES NORTH SIDE To control sun penetration to the interior of buildings it is important to provide exterior shading as a part of the architectural envelope design. The north elevation essentially does not require occurs. At this time of day the sun angle is so low that horizontal projections would be useless as shading devices. • It is best to provide fenestration on the north elevation as there will be very little solar heat gain Bin Saram Designs Delta Design & Engineering Pvt. Ltd. Lahore

24. SOUTH SIDE The south elevation allows for the easiest control of solar energy. Shading devices are normally designed as horizontal projections above the windows, Such shading devices can be designed to completely eliminate sun Rays in the summer Allow for complete sun penetration during the winter when such is desired for passive heat gain. EAST AND WEST SIDE The east and west elevations are both difficult to shade “architecturally”. The sun angles in the morning and afternoon are low enough to stop using overhangs. The morning sun is normally cooler and less offensive than the heat and glare of the late afternoon sun . Bin Saram Designs Delta Design & Engineering Pvt. Ltd. Lahore

LANDSCAPE Landscape is the architectural is the design of outdoor area, landmark, structure to achieve environmental social behavior or aesthetic SUKH-CHAIN NEEM TREE DECIDOUS TREE very shady tree Mosquito & Insect repel summer shade Bin Saram Designs Delta Design & Engineering Pvt.

27. ORIENTATION Take advantage of climate features such as sun and cooling breezes. Orientation means locating living areas like the lounge, room on the north side of the house, with windows having clear access to sunlight even in mid-winter. Effective Good orientation reduces the need for extra heating and cooling. The orientation of kitchen should be towards the east to allow the UV rays to destroy the germs that tend to multiply in the presence of moisture & food. Orientation provides a minimum of about five hours of useful solar heating a day. Bin Saram Designs Delta Design & Engineering Pvt. Ltd. Lahore

29. EARTH BERMING Earth berming reduces outside air infiltration, keeps temperatures cool in summer and warm in winter as the earth’s temperature at a depth of a Few meters remains almost stable yearly Berms may cover a part of the ground floor, sometimes entire buildings, provided daylight and ventilation requirements are taken care of. Needs adequate water-proofing measures. Basements are similarly cool and preferred spaces . Bin Saram Designs Delta Design & Engineering Pvt. Ltd. Lahore

32. Earth Air Tunnel Earth Air Tunnel System This system is viable if the ground below has good thermal capacity, for. e.g. soil with adequate water content Minimum Requirements Pipe depth 4m – Pipe diameter 0.3 to 0.7m – Distance between pipes 3m centre to centre Pipe length depends of air volume required.
