Energy Modelling of Buildings in India – Needs solid push.

Building energy modelling, is a field that can be described as computationally very intensive. Not long ago Energy Modelling studies were mainly preserved for the research institutions who generally had lot of computational resources at the disposal. Nowadays there are a large number of Open Source platforms which have arrived in the market and these tools can be employed on Building models with variety of options that an architect or energy modeler can have.

Deciding Facades of Commercial Spaces – Glass vs Brick

Facades have replaced the brick and mortar choices in commercial spaces in present times. There have been umpteen justifications in favour and against Brick or Glass facades.  India has typically overall hot climate with seasons classified as winter (December, January and February), summer (March, April and May), a monsoon rainy season (June to September), and a post-monsoon period (October to November). The Glass Facades in India are generally perceived as copy paste of Western Architectural style. In cold climates ideally Glass is a better proposition.  Indian tropical conditions  as Glass traps solar heat and warms up the building’s interiors. Continue reading “Deciding Facades of Commercial Spaces – Glass vs Brick”

Making Your Sweet Home Cozy

Whether you are living in independent house or in an multi storied apartment, you have always felt the need to optimize your energy bill and make your sweet home cozy.

Energy Modelling a Delhi Office Building

Energy Modelling Delhi Office BuildingOpen Office or halls without cubicles had arrived in office layouts over last few years. Quite a few companies have endorsed it for better productivity and also for building office relationships. There will always be strong views in favour and against any idea. Our intention here is not to  debate here further on to the adoption practices for new office layout guided by work culture rather we intend to look at energy modelling of a Delhi Building which is basically single floor setup and for all practical practices has been considered to be shadow free.

Energy Modeling requires Weather File and Design Days details in respect of the location where the building being considered for Energy Modelling is situated. Energy Modelling does carefully considers the weather data pertaining to that location. ASHRAE STD 169- 2013 Climatic Data for Building Design Standards provides weather and climate details about 3,012 locations outside the United States and Canada internationally.

Brickwork or Blockwork in Green Buildings

Green BuildingsBrickwork or Blockwork are the simplest units on the basis of which buildings are constructed. In Indian building construction, the predominant dimension of brickwork is 250 mm thk bricks with 12.7 mm of plaster on each sides. The thermal conductivity (U) of such construction is 1.98 W/m K. This is in fact the most commonly used construction practice in modern day construction in India. But gradually, the architects are realizing the necessity of having improved brickwork or blockwork construction with lesser thermal conductivity so as to have high thermal resistance and low thermal conductivity.

Energy Consumption in Delhi vs Mumbai Apartment – A Study

People today are gradually moving towards living in High Rise Multi-Storied apartments. Living in units in High Rises today is preferred due to better comfort, increased security, reduced cost of living and overall a better experience. Compared to independent villas, the carbon footprints of apartment dwellings are much lesser. The energy consumption also depends greatly on the location of your dwelling unit. We have tried to analyse and compared two locations in India, New Delhi and Mumbai. Continue reading “Energy Consumption in Delhi vs Mumbai Apartment – A Study”

Building Orientation Effect in Mumbai – A Short Study

Mumbai is warm and humid. There has been always a necessity to design a building which will be energy efficient due to its physical location, building orientation and layout. The example we describe here may not be practical but will definitely give an indication on how to orient a building to get maximum advantage. Maximum Dry Bulb Temperature of Mumbai is 35.8 Deg C. Continue reading “Building Orientation Effect in Mumbai – A Short Study”

Daylighting Consideration in Buildings

Present day buildings are generally having facade which is made up of Glass. Daylighting consideration becomes important here. The orientation of tall multi-storied buildings become very important as the spatial orientation is responsible for energy performance of the building throughout its life. The wider vertical faces are generally oriented towards either facing North or South direction so as to have lesser incident solar radiation on the buildings.
