F-7.3.1 Appropriate solar passive methods, such as orientation, double-glazing, trombe walls and solar collectors, shall be adopted to achieve climatic comfort with little use of conventional energy.
F-7.3.2 Care shall be taken in siting and design of buildings to provide passive controls to modify the effect of cold/strong winds.
F-7.4 The houses constructed on sloping land shall be protected by building retaining walls/breast walls [see good practices 3(11)] to avoid landslides occurring at time of earthquakes or heavy rains.
F-7.5 Maximum height of plinth level shall be .
F-7.6 On the uphill side of the building on a sloping site, the natural flow of the water shall be diverted away from the foundations.
The slope of ground all around building should be not less than 1:50, built in such a way that rain water does not find way to percolate in ground excessively and moves away quickly to surface drains or away on adjoining hill surface towards natural streams.
A minimum of wide apron should be provided all around the building to prevent entry of water into foundation.
F-7.7 Stepped terrace development and stepped storeyed building construction may be adopted for offices, schools and other building complexes because of following advantages:
a) It results in least hill cutting, disturbance to hill stability and also in least deforestation.
b) Cost of site development works, slope protection and other protection works is reduced considerably.
c) Least load comes on valley side, so danger of foundation failures is avoided.
F-7.8 Disaster Resistance
All necessary steps shall be taken in designing and building in hilly regions to achieve disaster resistance as per the relevant codes and Part 6 ‘Structural Design’ of the Code. All natural disasters likely to affect the locality shall be taken into consideration namely earthquakes, cyclones, avalanches, flash floods, landslides, etc. For guidelines for selection of various landslide control methods for effective correction measures to avoid landslides in hill areas, reference shall be made to good practice [3(12)].
