Development of Draft Protocol for Testing of Structural Components and Systems

(a joint initiative of MoHUPA under technology submission of Pradhan Mantri Awas Yojna & IIT, KANPUR)

Case Study on Performance Evaluation of HPL Buildings

  1. Background
  2. As we know, under the ‘Housing for All’ scheme of Govt. of India, approximately 2 crore houses are to be constructed and for houses to be constructed on such a large scale, it is crucial that margin of error (in maintaining quality of construction) is as minimum as possible. And many times such houses can also be non-conventional type, for which not much data/ standard literature is available. Hence it would be a good idea to study recent innovations in building construction and structural engg. in our country and see how these recent technologies perform in terms of durability, strength, economy, energy efficiency and thermal comfort when compared to a conventional RC frame building.

    Therefore, as a part of this project, a case study is being done to evaluate the performance of such buildings based on simulations and real time data. For the case study, newly constructed prefabricated buildings constructed at Technological park, Hindustan Prefab Limited (HPL), Delhi have been taken as ‘candidate buildings’ as these buildings having relatively smaller construction period, can be used as ideal candidates for ‘Housing for All’. Performance of these buildings will be evaluated based on following criterion:
    1. Structural Performance
    2. Energy Performance

  3. Case Study
  4. The case study will be carried out in two parts:
    1. Structural Performance:
    2. Under this category, detailed numerical model of candidate buildings will be prepared in SAP2000 and will then be analyzed for different load combinations to check the structural adequacy of those buildings against earthquake/other natural calamities. A preliminary model of one of the candidate building along with its original picture is given below:

      Pre-engineered Building with Sandwich Panels
                        Actual House                                                            Numerical Model


    3. Energy Performance
    4. Under this category detailed modelling of houses will be done in Transient System Simulation Software (TRNSYS 17) (Multi zone building tool) based on thermal air zones for different rooms and will then be analyzed for different climate condition, orientation, geometrical properties, shading etc. to check the adequacy of houses for reduced annual energy demand of the ventilation and air conditioning systems and improved thermal comfort of occupants. A preliminary model of one of the candidate building along with its original picture is given below:
