Consultancy for Solar Passive Designs of Private Buildings

Here is an opportunity to design your house/hotel/building by incorporating internationally acclaimed Solar passive housing technology. A Cell in the Council provides consultancy to public in Himachal Pradesh at nominal charges. Consultancy for retrofitting of old houses with solar passive heating systems is also available.

Solar passive Judge's House at Shimla
  1. Environmental friendly
  2. Low energy bills
  3. Comfortable living conditions
  4. Low maintenance
  5. Clean and hygienic
  6. No operating noise
A maximum saving of 60-70% on conventional fuels required for space heating during winters and cooling during summers can be achieved. Large windows and views, sunny interiors, open floor spaces, warmer in winters, cooler in summers resulting in comfortable living conditions even during power failures, durable, reduced operational cost, independent from future rises of fuel costs, clean environment to combat growing concern over global warming and ozone depletion are the main features.


The incorporation of passive solar features in a new house will not normally require extra expenditure. The houses under consideration can be divided in three main categories:

  1. Houses where choice of proper orientation and site planning and efficient functional planning is possible, energy efficiency can be achieved at no major extra cost.
  2. Houses for which there is less availability of sunlight, less independence in selecting the site and orientation, there is an increase of only 5-10 % which may be required for greater levels of insulation, special heating and cooling requirements. However, due to lesser fuel /electricity consumption year round, this incremental cost can be recovered within 5-7 years.
  3. Houses which are to be retrofitted with Space heating solar passive systems like Trombe wall, sunspace, space heating green houses, adding insulations will require extra funds.
Guidelines for New Solar Passive Houses

Stage-I: Preliminary Data Collection & Site Visit

  3. Optional: Obstruction survey to find the availability of sunshine could also be carried out if required [extra charges].
Stage-II: Analysis & Designing
  1. Analysis of Site data, climatic data, heating & cooling requirements of house will be carried out by the Cell
  2. Based upon the analysed data, the architect will prepare conceptual designs
  3. Conceptual designs will be discussed with client
