BUILDINGS PERFORMANCE HOW WE DETERMINE THE SUSTAINABLE PERFORMANCE

COMFORT ZONE To Determine the Performance of the House at a particular location first the Climate Zone and environment at the particular location is studied. The Comfort level that is available at the location is examined to option the maximum level comfort for the occupants. Then best Design strategies which will improve the occupants comfort with very less or no mechanical energy is applied.

Chart showing the Temperature Range prevailing in the location

The above analysis of the Climate in our proposed location shows that the Comfort Zone for the Loca-tion is between 30-23 Degree Celsius.It means the occupants are more comfortable at this location when the temperature range is in between this frame.Now our Objective is to Design a Buildings per-formance model which will be having a temperature range in between this prescribed Value.

The result shows We need to Apply Cooling strategies in the months of March,April,May,June,July and August. The Months of January,February,September,October,November and December are more cooler and Closer to Comfort level.

RADIATION RANGE The Buildings ability to make a comfortable dwelling for its occupants is related to the climate around it, especially how well we avoid the sun when over heating happens and how well we utilize the sun when we cooling is required. That is maximum Shading during Summer and Maximum exposure dur-ing winter and Cooler seasons.

A building is heated by the sun in three ways through Radiation,Convection and Conduction.

Chart Showing the Radiation Range in Location The best Design Strategy which will reduce the effect of suns radiation,Convection and Conduction during summer is applied to the EEBPM Model.This will Increase the ability of the House to give more comfortable atmosphere to its occupants in summer by avoiding heat generated by direct sun’s heat-ing.

Heat Transferred through Air Convection is reduced by applying proper insulation which will avoid air being heated by having contact with Hot Building envelope which is being directly heated by the suns radiation.

7

WIND AND VENTILATION Air quality inside a House is directly related to the ability of the building to intake natural air at vari-ous zones. A house with Poor air quality would be suffocating and less comfortable.A proper Design Strategy is required for better utilization wind and ventilation.

Chart Showing the available Wind Wheel,its Temperature and Speed for the Location

The Design strategy for Maximum Occupant comfort with no or less additional energy by using wind would be to avoid Hot and Humid Air but to allow Cool and Wet air Inside the building.A House De-sign with Maximum intake of cool air and avoiding Hot air is Developed.The EEBPM model uses cool air from the North East side during the months of November,December,January but will avoid The Hot and Humid Air from South East during March,April May and June.

By proper Wind and Ventilation Design strategy can improve occupants comfort and Internal Air qual-ity of the building.

The Mean Air Temperature Graph shows the temperature Difference in Bed room 1 of the Two Models. NDPM have Temperature range from 28-47 Degree Celsius where as EEBPM have a temperature range from 28-34 degree

celsius.During Summer it will be very uncomfort-able in the Bed room 1 of NDPM where as there is very low and study change in EEBPM. It will be more comfortable and we can avoid having

Air Conditioning in the EEBPM.

Mean air Humidity ratio of NDPM and EEBPM shows how much humidity will be there in the Bed room.Higher the humidity more Uncomfortable.so we can deter-mine that the EEBPM will be more comfort-able and energy efficient because there is no need for Dehumidifying and Condi-tioning where as NDPM requires dehu-midifying or conditioning to make it Com-fortable to occupy during peak hours..More humid area create more un-comfortable sweating and heat.

The above graph shows the comparison of Tem-perature in Living room in NDPM and EEBPM.There is a big difference in temperature range.NDPM has a temperature wave from 28-50 degree celsius. In March and April it even reaches to 50 Degree which will be very un comfortable for occupants. in NDPM model air conditioning is necessary.

Where as EEBPM has Temperature wave from 33-39 Degree celsius which can be made com-fortable with a ceiling fan.there by making this more energy efficient model.

Mean Air temperature Comparison between NDPM VS EEBPM for Living

PERFORMANCE RESULTS FOR LIVING AREA

Mean air Humidity ratio of NDPM and EEBPM shows how much humidity will be there in the Living area .Higher the humidity more Uncomfortable.so we can determine that the EEBPM will be more comfortable and energy efficient because there is no need for Dehumidi-fying and Conditioning where as NDPM re-quires dehumidifying or conditioning to make it Comfortable to occupy during peak hours.More humid area create more uncomfortable sweat-ing and heat.

To further improve the performance of the House Design and to Get the maximum comfort with very less Energy some of following strategies also can be applied. This design strategies will im-prove the sustainable performance of the house and the living comfort. These design strategies will reduce the energy consumption and are friendly with nature.

ABOUT THIS RESEARCH

Building Sustainable Performance and Energy analysis research is the initiative of the iBIMS to help every one to understand how we can improve the sustainable performance of the building by better understanding the Nature and climate around it. The result shows a huge improvement in the quality of living by increasing the comfort and a big saving for the occupants in energy and Money.

WHAT CAN WE ACHIEVE BY OPTING TO DESIGN PERFORMANCE MODEL FIRST AND THEN THE

ARCHITECTURAL MODEL I. saves money

II. saves energy

III. A better performing building which will give you comfort on all the seasons and climate.

IV. Reduced Carbon dioxide emission

V. Saves nature from Climate change

VI. Increases the life of the building

DIFFERENCE BETWEEN ARCHITECTURAL MODEL AND A SUSTAINABLE PERFORMANCE MODEL

An Architectural Model is the Technical Details prepared for the smooth execution of construction where as A Sustainable Performance Model is a guideline for making the proposed buildings per-formance in harmony with nature around it.

Building performance model is the core on which the architectural model has to be developed. it does not have technical details of the materials or Components but it predicts the behavior of the components in the building.

A building sustainable performance model will make the occupant to understand the building better and to live according to the changes in the Environment.

ABOUT IBIMS We are iBIMS (innovative Building Information Modeling Services). We’re an innovative startup work-ing on a fun-to-work and highly creative online service that will make a meaningful difference in how we live and how we interact with this beautiful nature.

if you are planning to build or design your Dream Home or a building you would have noticed some of these problems:-

1. Felt very Uncomfortable and Hot at certain buildings during summer

2. Felt certain parts of the Buildings are too dark and gloomy

3. Felt certain parts of the buildings have very bad air quality and tend to suffocate while there.

4. Felt certain areas of the buildings are too chilling than others.

5. Felt some are paying too much Utility and Energy Bills for making it comfortable inside?

6. Felt certain buildings are unfriendly with Nature and causing too much problems when there is a change in climate

You know, the real purpose of the buildings was to give you Comfort and to be a Peaceful dwelling. Why does this happen even when they have spend too much for constructing it.

That’s Exactly why iBIMS have come with our innovative service to find the PERFORMANCE OF YOUR BUILDINGS DESIGN on various climatic conditions.

We offer real-time BUILDING PERFORMANCE SIMULATION. A buildings design is performed against the weather conditions to find the change in buildings properties and effect on its inhabi-tants. We can simulate with different Building properties to reach a model that will be the most effi-cient and the best performing model.

All this can be done before your building is being constructed. This will save you a lot of money and Energy and will give you a Building, which is Friendly with nature and you.

Ok, Now you might be thinking what type of buildings and who can apply for it. Any type of build-ings around the world, Small or huge, A big hospital or a small home can check its performance. And the technical data required are simple details like location, Geometry, Occupancy, Loads, Equipment’s etc. that anybody can furnish.

Building Performance simulation is more effective when done at the Design stages of the project rather than doing it at the time of rebuild or retrofit.
