V i s i t o r ’s C e n t r e S t a n d s fo r t h e s e va l u e s .Our efforts are to preserve the existing natural beauty of the site and continue to enhance and embellish the forest greenway utilizing the space with integration to the natural site.

AN OVERALL APPROACH TO DESIGN IN ORDER TO GENERATE AND UNDERSCORE THE SENTIMENTAL VALUES AND EXPLOIT THE POTENTIALS OF AQUALAND.

D E S I G N PA R A M E T E R S

The architecture to house it , itself needs to have a character to be gracious to the environment.It will thus bring under spotlight, the Need for a sustainable living environment which creates/contributes to conserve the available resources, and set an example for importance of saving , for better tomorrow.



V I S I O N F O R V I S I TO R C E N T R E

AQUALAND visitor Centre shall be a world class building that shall blend the strong vision of Aqualand with Aesthetics and qualified SCIENTIFIC PASSIVE strategies and techniques which shall be a constant source of inspiration and benchmark for the future PARTNERS of Aqualand.

SUNPATH OVER EXISTING SITE LOCATION PLAN

The proposed location of the visitor centre is located to the south of Mulshi Lake at an approximate altitude of 900 meters above sea level. The site is locate in a rural setting and has no substantial structures nearby which might potentially cause overshadowing or micro level wind directional changes.

A detailed site analysis was carried out using the Weather Tool software developed by Square One Research.The results of this study, guide the design process in a climate sensitive manner, making the best use of the available site conditions.

DESIGN STRATEGIES AND PASSIVE TECHNIQUES

The following input parameters were considered to the desired outcomes from the weather tool :

Location Coordinates-Latitude 18°3' NLongitude 73°3' EAltitude 900mOperational Hours -08:00 - 20:00

Weather Data File :Energy Plus weather data file for Pune, based on detailed hourly readings recorded in ISHRAE Handbook was used as the base file.This file was customized by updating the altitude to 900 m and the rainfall data to suit Paud region

SUNPATH DIAGRAM

The low angle summer sun during early morning and late afternoon would cause issues of glare and overheating on the northern walls.

DESIGN CONSIDERATIONS : Sun shading devices are proposed on the northern face as an integral part of the design process in response to the sun angles.

An option of occupant control over the shading devices is presently envisaged to provide flexibility over the internal environment.

WINTER SUNPATH




WIND ANALYSIS

The prevailing wind direction during the hot summer months is WEST, with more than 500 hours recording wind speed of 12km/hr.

We anticipate larger wind speeds for the visitor centre site, due to its exposed terrain and higher altitude, as compared to Pune.

DESIGN CONSIDERATIONS : Use of wind tunnels, wind barriers and landscape elements towards the west and southwest, is the primary design response to harness wind energy and adapt processes to dehumidify and channelize the air flow through the visitor centre assisting natural ventilation process.

ESTABLISHING AN AXIS -

Optimum Orientation of Visitor Centre:

The best orientation for a vertical surface is when there is the most solar radiation during the under heated period and least during the overheated period.

This NE-SW climatic axis coincides with the natural view corridor from the visitor centre, which is, Mulshi Lake to the north east and part of Temghar Lake and southern slopes of Aqualand Development to South West.

Optimum OrientationLocation Mulshi, IND

Orientation based on average daily incident radiation on a vertical surface

Avg. Daily Radiation at 9.0°Entire Year: 0.15 kWh/m²

Under heated: 0.12kWh/m²Overheated : 0.34 kWh/m²






MONTHLY DIURNAL AVERAGES DAILY CONDITIONS

The difference between the highest and lowest daily temperature is on average 10°C. Highest temperature is recorded in middle of May and the coolest temperature during end of December. Monsoon months receive the lowest amount of direct and diffuse solar radiation due to over cast sky conditions.

COMFORT PERCENTAGES:

Individual graphs provide the increase in comfort percentage each design strategy contributes in a year.

Passive design strategies greatly increase the comfort factor throughout the year. Comfort factor of over 90% is achieved for almost 6 months of the year by combining all six passive design strategies.

This provides tremendous potential to exploit mixed mode air conditioning strategies, resulting in SUBSTANTIAL COST SAVINGS DURING INITIAL SETUP AND OPERATION OF THE BUILDING.

D E S I G N G E N E S I SBASED ON SITE ANALYSIS



Considering the climatic conditions of the site, passive design strategies such as thermal mass, natural ventilation, evaporative cooling are at the core of conceptual design of the Visitor Centre. This building should act as an exemplar for the future development and should reflect Aqualand's commitment to providing ENVIRONMENTALLY FRIENDLY CONTEMPORARY DEVELOPMENT.


A base of case studies and resources needs to be established to illustrate the sustainable design strategies and features in realistic building projects all over the world.

Although new technologies are constantly being developed to complement current practices in creating greener structures, the common objective is that green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:•EFFICIENTLY USING ENERGY, WATER, AND OTHER RESOURCES•PROTECTING OCCUPANT HEALTH AND IMPROVING EMPLOYEE PRODUCTIVITY•REDUCING WASTE, POLLUTION AND ENVIRONMENTAL DEGRADATION

•The façade consists of bristling brise-soleil composed of anodized aluminum fins suspended from tensile rods. •The striking facade acts as a rain screen while filtering sunlight and contributing to the building’s energy efficient profile.•The fins are placed carefully considering that early morning and winter sunlight is able to enter the building while high summer sun is excluded and so does not adversely alter the environmental conditions within the building.

GLOBAL CASE STUDIES

Strong concept + Passive Strategies to save energy by Scientific simulations and Quantified techniques + Aesthetics = Iconic Design with Integration of Green



•To help alleviate the heat gain from the sun, the units are surrounded with a 1.5 meter terrace enclosed with bamboo louvers.•The screens while helping diminish the solar gain to the units are turning the facade into an always changing kaleidoscope of shadow and light.•The screens protect the glazed surfaces from the strong East-West solar exposure, and are able to open to the side gardens when desired.

GLOBAL CASE STUDIES




•The building is elevated off the ground, sucking air in around the edges of the building which is eventually released up through the open-air courtyards, cooling the building inside at 27° Celsius even when it is 47° Celsius outside•A large stepped well in the center of the building helps lowering the temperature of the air as it enters under the belly of the building.•Use of “Jali”, the screen is used as a thermal skin between the building and the surroundings.•A 4-foot gap between the screen and outdoor wall of the classrooms reduces direct heat gain. Drip channels on the inside of the screen provide more evaporative cooling.

Few questions to be discussed: 1) Are we looking at designing a World Class building (some cases studies to sight what this means), to showcase Aqualand's

commitment to future development? If yes, then are resources made available, in terms of time & funding.

2) Secondly, commitment to green building strategies, especially, LEEDS rating, this will require additional funding at the design stage, but will result in setup & operational cost savings.

3) Openness to new ideas in terms of design and construction strategies and to involve best people to achieve this.



V I S I T O R C E N T R E

The basis of our design thus revolves around these techniques. In order to incorporate them into design at preliminary stage we would require inputs from Green Building Consultants.
