Ecology Energy and maintenance Water management Materials Comfort of occupants Transport and social issues

Ecology is our project sustainable theme top priority because it is located in a polluted city center where heat islands are a problem. To increase neighborhood sustainable value, our project will include :

• Vegetated roof (more than 70% of project roof surface)
• Species with low allergenic potential
• Vegetated walls (about 30% of total project wall surface)
• High reflectance external soil …

Plan depicting the composition of the wall structures

 This plan should illustrate :

 Structural elements  Insulation thickness  Windows and doors

17

The completed Excel eco-design tool  The eco-design tool allows you to assess your project through 7 bioclimatic quantitative criteria  You should sort these quantitative criteria like the environmental issues to optimise the most pertinent for your project based on your project site analysis  To guide you some values are proposed in the tool to help you estimate if your project is closer to a low or a good value  You should try to enter your project datas several times to

• ptimize it through bioclimatic quantitative criteria.

The completed Excel eco-design tool

 The eco-design tool allows you to assess your project through 7 bioclimatic indexes :

 Compactness  Opening surfaces  Level of insulation  Level of thermal loss  Solar gains in summer  Solar gains in winter  CO2 index of materials

The completed Excel eco-design tool

 The 5 bioclimatic indexes :

• 1. Compactness =

The completed Excel eco-design tool

 The 5 bioclimatic indexes :

• 4. Level of insulation en W/(net floor m².K)

Unlike the level of thermal loss (Ubdg), the level of insulation is brought down to the net floor area and therefore penalizes building that have heights.
