Deliverables 8

Deliverables  Material for environmental section Site plan identifying the advantages and constraints of the site Analysis of the environment and reasons for choosing the site Ranking of issues according to the site context Description of how each sustainable building theme was dealt with Bioclimatic section illustrating heat strategy Bioclimatic section illustrating cold strategy Bioclimatic section illustrating natural light strategy Plan depicting the composition of the wall structures The completed Excel eco-design tool 9

Deliverables Site plan identifying the advantages and constraints of the site Potential advantages of a site  examples : Bus stop  Train station  Cycle network…  Potential constraints of a site  examples : High traffic avenue/road  Noise source…  1 0

Deliverables Analysis of the environment and reasons for choosing the site  Written analysis and conclusion about : Advantages and constraints of site  Why the site is important and chosen  Association between identified advantages/constraints and  sustainable building theme 11

Deliverables Description of how each sustainable building theme was dealt with  Written description about how the chosen strategy is dealing with each theme  Expected precision will vary based on your environmental issues hierarchy  For main issues : concrete elements, measurable calculation notes should be included 12

Deliverables Ranking of issues according to the site context Site A Ecology Energy and maintenance Water management Materials Comfort of occupants Transport and social issues 13

Deliverables Description of how each sustainable building theme was dealt with  Example : Project A Ecology is our project sustainable theme top priority because it is located in a polluted city center where heat Ecology islands are a problem. Energy and maintenance To increase neighborhood sustainable value, our project will include : - Vegetated roof (more than 70% of project roof surface) Water management - Species with low allergenic potential - Vegetated walls (about 30% of total project wall surface) Materials - High reflectance external soil … Comfort of occupants Transport and social issues 14

Deliverables Plan depicting the composition of the wall structures  This plan should illustrate :  Structural elements  Insulation thickness  Windows and doors 16

Deliverables 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 optimize it through bioclimatic quantitative criteria. 17

Deliverables 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  CO 2 index of materials 18

Deliverables The completed Excel eco-design tool  The 5 bioclimatic indexes : 1. Compactness = ∑(𝑥𝑏𝑚𝑚,𝑠𝑝𝑝𝑔,𝑚𝑝𝑥𝑓𝑠 𝑔𝑚𝑝𝑝𝑠 𝑏𝑠𝑓𝑏𝑡) 𝑈𝑝𝑢𝑏𝑚 𝑜𝑓𝑢 𝑔𝑚𝑝𝑝𝑠 𝑏𝑠𝑓𝑏 The lower compactness is the lower thermal loss will be important. Reference values Low good 3 ,3 2 ,6 2 19

Deliverables The completed Excel eco-design tool  The 5 bioclimatic indexes : 2. Opening surfaces = ∑(𝑕𝑚𝑏𝑨𝑓𝑒 𝑏𝑠𝑓𝑏) 𝑈𝑝𝑢𝑏𝑚 𝑥𝑏𝑚𝑚 𝑏𝑠𝑓𝑏 The higher the glazed surface will be the higher visual comfort and sun thermal gain will be. Reference values Low good 0 ,1 3 0 ,1 7 0 ,2 0 20

Deliverables The completed Excel eco-design tool  The 5 bioclimatic indexes : 3. Level of thermal loss en W/(m².K) = ∑(𝑡𝑣𝑠𝑔𝑏𝑑𝑓∗𝑁𝑏𝑢𝑓𝑠𝑏𝑗𝑚𝑡 𝑢ℎ𝑓𝑠𝑛𝑏𝑚 𝑢𝑠𝑏𝑜𝑡𝑛𝑗𝑡𝑗𝑡𝑝𝑜) 𝑈𝑝𝑢𝑏𝑚 𝑥𝑏𝑚𝑚 𝑏𝑠𝑓𝑏 Thermal resistance (R) = thickness (e)/Thermal conductivity (ʎ)  Thermal loss (U) = 1/Thermal resistance (R) Heat transfert Outside cladding Structural elements Outside Inside Insulation Reference values Structure Low 0 6 good ,4 5 0 ,4 0 0 ,3 21

Deliverables 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. Reference values Low good 0 ,7 0 ,6 0 ,3 22

Deliverables The completed Excel eco-design tool  The 5 bioclimatic indexes : 5 and 6. Solar gains in summer and winter Solar gains are approached by calculating an equivalent south window surface. Reference values ISE winter N Building project plan Equivalent ISE summer south window Solar gains 23

Deliverables The completed Excel eco-design tool  The 5 bioclimatic indexes : 7. CO 2 index of materials (kg CO 2 /m²) = ∑𝑡𝑣𝑠𝑔𝑏𝑑𝑓∗𝑛𝑏𝑢𝑓𝑠𝑗𝑏𝑚 𝑕𝑠𝑓𝑧 𝑓𝑜𝑓𝑠𝑕𝑧 𝑡𝑣𝑠𝑔𝑏𝑑𝑓 CO 2 CO 2 CO 2 index Energy  24
