Energy Efficiency and Green Building - some observations Гай Имз, Генеральный директор, Совет по экологическому строительству Имз Гаи Ген Директор RuGBC
Energy Efficiency versus Green Building (1) Green Building ( Energy Transport Water Health & Well-being Waste Renewables Materials Management Pollution Energy Efficiency Energy Certificate / Passport (EPC) Energy Labelling of Appliances kWh/M2/PA Имз Гаи Ген Директор RuGBC
Energy Efficiency versus Green Building (2) Green Building = resource efficiency & energy efficiency Energy Energy- Generation / sources of WaterEnergy / Resources - Power to pump, extract, treat Waste / Materials Energy / Resources - Embedded energy (extraction, production, transport, recycling / disposal ManagementResources (human) Pollution Type of Resource Transport Energy Health & Well-being Energy Renewables Energy Имз Гаи Ген Директор RuGBC
Energy Efficiency versus Green Building (3) Green Building = resource efficiency & energy efficiency Summary – Green Building Concept offers much deeper examination of “efficiency” ideas – which in turn can save money & raises levels of human comfort Particularly ignored – transport, waste, water, building management Имз Гаи Ген Директор RuGBC
Another Green Building role– Reduce the demand: Passive versus Active • Many examples of lighting systems installed “to save money” when actually much better solution is to use natural lighting • => Solution –for optimisation use lighting control systems with sensors for zoning & switching on where needed at the right levels Имз Гаи Ген Директор RuGBC
The rebound Effect • Energy Use & Satisfaction • Improvements in technology / innovation => cheaper services provided, leading to higher demand • Lighting levels - Today in UK avg person uses 25,000 x more light than in 1800 • Appliances in homes (electrical) • Automobiles • By 2025 52% of energy savings will be used by increasing use (Cambridge Uni 2009) • Universal chargers with zero standby charge • Building design (passive – lighting / heat) • Good design with no need for cars Имз Гаи Ген Директор RuGBC
IT – ignore it at your peril! • - Information age – instant access • - Instant access = not switching off devices • - Huge energy costs (servers/storage, networks) 5% • - Potential to use up all the energy we “saved” in other areas • Gradual realisation of the effects, ideas to base servers (data centres) on sea, cosmos! • Higher efficient chipsets (eg netbooks) Имз Гаи Ген Директор RuGBC
Europe vs Russia – opposite drives for Energy Efficiency in heating • Europe – drive for “District Heating” • Russia – drive for “Individual boilers” Имз Гаи Ген Директор RuGBC
Europe versus Russia – opposite drives for Energy Efficiency in density • Different ideas of “sustainable” density of properties • Low-rise vs High Rise Имз Гаи Ген Директор RuGBC
Ignoring the sun as energy source • “Renewable energy is too expensive” • All energy is from the sun (oil, gas, coal, bio-fuels, • Plants, food etc)* • => Passive heating / orientation • => Chinese solar hot water systems • => People adapting to their environments, not • vice versa • * Except geothermal Имз Гаи Ген Директор RuGBC

Solar Cooling • Hot climate = abundant energy source (direct or indirect heat from the sun) • => Opportunities for “autonomous” buildings, • concept of Summer versus Winter regimes Имз Гаи Ген Директор RuGBC
Europe versus Russia – Connection Costs vs cost per kWh • Europe energy companies fighting to connect clients, • talk about “payback” for users for EE technology • Russia – high connection costs, relatively cheap operational costs • => “Instant” payback for green building in Russia • => Gradual move towards “energy servicing” in R concept in Russia Имз Гаи Ген Директор RuGBC
