Cost Effective and Energy Efficient Buildings/Disaster Resilient Buildings
Concrete Hollow Blocks (CHB)
Concrete Hollow Block (CHB) is a walling material, applicable to both load bearing and framed structure buildings, designed with respective guidelines to fit the necessary requirements.

CHB has potential use in construction sector due to the following reasons:
  • It can be produced locally or in a large scale with technical supervision. It can also be produced in households with simple techniques and low investment.
  • It has speedy construction as compared to brick masonry, which reduces labor cost by 40%.
  • As compared to traditional brick masonry (9" Ordinary English Bond Masonry), CHB has higher potential in reducing Carbon Dioxide (by 30%) and saving material cost (by 25-30%). Even if only 10% of construction in the country would use this technology, around 22,150-ton CO2 reduction is possible.
  • With the consistent rise in price of clay burnt bricks, the demand for CHB is likely to continuously increase in future.

Services offered by us:

  • Supporting and training of existing as well as new enterprises that produce quality blocks (machine-made or hand-made)
  • Carrying out Research and Development, and producing high quality products
  • Design and quality supervision for the application of CHB
  • Time, cost and material estimation in CHB Masonry units
  • Fine-tuning of existing designs
Mix design - Natural Round Aggregates (NRA)
Natural Round Aggregates are found naturally in riverbeds. When used in concrete mixes, its round structure ensures the highest economic production. In terms of construction application, NRA can be used in all structural elements (column, beam, slab, foundation, concreting) of the buildings as well as in cement based precast building material production.

Advantages of NRA:
  • Use of NRA in preparation of concrete mix results in ~15-20% savings in the quantity of cement used and 7.7 % savings in CO2 as compared to using crushed aggregates
  • Since it is found ready-for-use in nature, it is economically profitable to use NRA as compared to crushed aggregate
  • Contractors, masons, and all workers involved seem to prefer NRA as it reduces work stress and raises productivity

Services offered by us:

  • Training for site supervisors and personnel on how to work with NRA
  • Assistance in the concrete mix design (grading the mix, raw materials)
  • Supervision of the entire NRA concreting work
  • Promotion of NRA concrete mixes among contractors
Rat Trap Bond (RTB)
Rat Trap Bond (RTB) is a walling technology in which bricks are laid on an edge, such as the shiner and the rowlock are visible on the face of the masonry (brick cross), thus creating an internal cavity bridged by rowlock. It can be applied in both load bearing and framed structure buildings. It has been included in Government Norms and Standards and official occupational profile of the Nepal Skill-Test Board (NSTB). Presently, more than a hundred buildings (residential, hospitals, schools, commercial) already exist using the RTB technology.

Advantages of this technology are:
  • 15 - 20% less cost of walling compared to Ordinary English Bond masonry.
  • Buildings and houses constructed with RTB are disaster resilient (from earthquakes), energy efficient (especially its large conservation of CO2), economically efficient
  • Masons can easily be trained in use of RTB in the construction of buildings by available skilled and experienced masons
  • This technology uses 200% less bricks, 40% less cement mortar and results in 30% less CO2 compared to 9" Ordinary English/Fleming Bond masonry
  • RTB walls are around 35% lighter in weight than English bond structures, which support cost effective designing of frame elements in high-rise buildings
  • RTB also gives better sound insulation, adding to thermal comfort of the inhabitants

Services offered by us:

  • On-the-job training to contractors, masons and supervisors
  • Design and quality supervision for RTB application
  • Support in fine-tuning architectural designs to incorporate RTB more effectively
  • Estimation and calculation of cost and materials needed for specific RTB masonry cases
Concrete door and window frames (CDWF)
Concrete door and window frame is a precast element produced by casting cement, sand, aggregate and steel in a wooden or steel mold as per the required size and design. It is a substitute product for replacing conventional timber and aluminum frames for wall openings.

Advantages of using CDWF against timber or aluminum frames:
  • It contributes to reduction in carbon sinking and deforestation (since timber is increasingly becoming scarce and expensive)
  • The use of CDWF as compared to timber or aluminum frames has 30% to 40% cost savings
  • The skill required for the production of the CDWF frames is not very difficult, and someone with construction experience can easily be trained on it

Services offered by us:

  • Training of existing as well as new enterprises in the production of quality door and window frames using concrete as per the demands of the clients
  • Support and training of masons and supervisors in the application of frames
  • Design and quality supervision for the application of the frames
  • Estimation of the cost and material to be used
  • Fine-tuning of existing frame designs
Green Building
The Green building concept is a relatively new idea in Nepal. A building can be termed as 'green' when it is effectively and responsibly integrated into the natural environment in such a way that the protection of available natural resources is achieved. Energy conservation and water conservation are critical considerations in the designing of such buildings to ensure maximization of energy & water efficiency capabilities (e.g. by use of water reuse/recycle) of the building.

  • The architectural and structural design of Green building
  • Carrying out energy audit of existing building designs and providing suggestion of energy efficient changes within the existing features of a building
