Insufficient thermal regulations are risky
• Summer conditions too often neglected (TS825 in 2000)
• Details are very important: place of insulation, inertia, infiltrations, solar protections, window to wall ratio to West...
• Insulation + external wall: outside max. built area coefficient (Lebanon 2004)
• Regulation + Controls? + Communication for better design than standard

Insulation but inside, low inertia, Summer low comfort

Energy & Water tariffs: a neglected toolkit
• Gas & Electricity prices must be balanced
• Electricity tariffs should carry a kVA component
• Social step(s) tariff need good communication…
• Time of Use tariffs also for Households & Commercial if many A/C
• Role for distribution Co in liberal market: promoting energy & water savings?

Updating professionals on optimal design, by life long training
• Architects & Engineers together in courses!
• Good practices & Simulation models are complementary
• Fine adaptation to local climate profiles…
• Various profiles of occupancy: residential, schools, offices…
•Heating Degree*days base 18ºC
Cooling Degree*Days base 22ºC

Monitoring of existing buildings: real data are convincing!
• Monitoring of banal occupied buildings shows the critical periods for comfort, kWh & water uses, load
• Appliances are part of the analysis: fridges react to room temp.(DZ)
• EPBD: Energy audits & performance certificates need good reference data & training….

Adapting common financing tools
• Financing over-cost for lower operating cost is less risky for banker, then lower rate expected!
• Sparing scheme then loan + public bonus, for more sustainability ! (in FR= P.E.Logementk 15k€)
• Municipal support to soft financing (via energy environmental fees) might help to improve quality & to control added value

Toward Sustainable Cities:no more 1 person per car? no more toilet flush ?
• Mobility = more energy uses & pollutions than buildings
• Urban planning & modal shift are essential
• Remove barriers against District Heating & Cooling
• Promote local water processing & re-use, by price quota, per person or equivalent person?
• Flexible Working time, e-working, societal changes add complexity…
• Good local policies can make differences... but…
