Three Frames of Reference

♦ 1. Shodhgram at

Gadchiroli a tribal village project by Dr. Abhay and Rani Bang

Sevagram at Wardha

♦ 2. A vision for the twenty first century village by

Mahatma Gandhi which wonderfully balances ECOLOGY, ECONOMY & SOCIAL JUSTICE !

Hundertwasser Haus - Vienna

♦ 3. Tree tenants, window

rights and salvaged relics used to enrich urban living in urban public housing.

QUICK ASSESSMENT USING THE WEB FOR 3 INSTITUTIONS ♦ The web was used to get a quick feedback on the building practices

employed by the firm in the recent past. Three medium sized buildings with similar uses and sizes were compared to demonstrate the efficacy of the TOOL. ♦ The judgement of the partners was used to give rankings of bad, average, good, and excellent to the various sustainability indicators. ♦ Climate responsiveness of a building, which was not considered at all during the workshop, was introduced, as it was considered a prime factor in assessing sustainability. ♦ Non availability of data for ecological indicators was seen as a problem. The judgement of the partners here was used to give values to the indicators.

INFLUENCE OF LOCATION Factors affected by location of site in Urban Area: •Land Cost, availability and buildability (FSI) •Returns on Investment •Material and labour Transport Cost

NICMAR CAMPUS AT BALEWADI

NICMAR is characterised by a low-rise campus developed over a period of three years. It encouraged experiments with cost-effective and ecologically sustainable building techniques. The campus is an outdoor museum of NINE different building techniques.

PRACTICAL EVALUATION TOOL SOME INDICATORS TOWARDS A COMMUNITY OF PRACTICE ♦ Sustainability of a building is a subjective virtue that cannot be

assessed precisely due to lack of sufficient data and agreement on sustainability standards and benchmarks. ♦ Assigning index values to each of the indicator can be used to evolve a measuring system for the sustainability of a building. This will minimize the subjectivity inherent in the human angle if not completely eliminate it. ♦ A guiding body should be formed that would authorise the valuers for Sustainable Building Practice and constantly refine the tools. ♦ Differences of building type, project size, region and frame of reference will demand varied weightages on different indicators.

PRACTICAL EVALUATION TOOL SOME INDICATORS TOWARDS A COMMUNITY OF PRACTICE ♦ A database of such evaluations over a period of time will

help the guiding institution to authoritatively promote, guide and compare SUSTAINABLE BUILDING PRACTICES. ♦ Construction Financing Institutions, Planning Authorities and Institutes of Professionals could be asked to insist on evaluations and lend finance, give permissions or credibility/subsidies based on evaluations.

STAKEHOLDERS OF THE PROPOSED COMMUNITY OF PRACTICE ♦ CONSTRUCTION INDUSTRY ♦ BLDG. MATERIAL MFG. INDUSTRY ♦ GOVT. AND ITS REGULATORY BUREAUCRACY ♦ INSTITUTIONS WORKING IN THESE AREAS ♦ CONSULTANTS & LABORATORIES ♦ ASSESSORS: Professionals with min 10 years of

experience in relevant areas of environment, construction, social work.

Our structures are far away from those of the birds and the bees. Let us try and understand how they build with nature …………
