Overview
  • A Few Words about BPIE
  • EU Building Policies opportunities challenges
  • Why care about ventilation air-tightness?
  • Airtightness in New and Existing building
    policies
  • Concluding remarks

BPIE
  • Non-profit association in Brussels operational
    since Feb 10
  • Founding partners eceee, European Climate
    Foundation, Climate Works
  • Focus on energy efficiency in buildings
    throughout Europe
  • Centre of expertise in buildings (technical
    expertise)
  • European centre for a global best practice
    network
  • Targeted independent research, policy analysis
    evaluation to support policy implementation

EU framework
  • EPBD (2002/91/EC)
  • Definition of requirements for the energy
    performance of buildings
  • methodology for calculating the energy
    performance of buildings
  • scheme of assessing the energy performance of a
    building (EPC)
  • Mechanism of regular inspections of heating air
    conditioning systems
  • EPBD (2010/31/EC)
  • New nearly-zero-energy buildings constructed
    after 2020 (public sector buildings in 2018)
  • A harmonised calculation methodology to push MS 
    minimum energy performance requirements towards
    cost-optimal levels
  • Existing building stock shall be renovated to
    very low-energy standards (no specific target be
    set for the renovation of existing building).
  • For major retrofits the 1000 m² threshold is
    eliminated .
  • A more detailed and rigorous procedure for
    issuing EPC
  • EU 2020 20/20/20 Target

Energy Efficiency Plan 2011
  • Non-binding targets
  • MS to set their own indicative targets
  • EC to review progress in 2013 and propose binding
    targets for all MSs if it appears the 20 target
    will not be achieved.
  • Public Sector
  • Set an example
  • Renovation rate to be doubled to at least 3 per
    year
  • Renovation should bring buildings up to level of
    the best 10 of national building stock
  • Energy efficiency standards to be incorporated
    more fully into public procurement.
  • ESCOs
  • Both the private and public sectors
  • Legislative proposals to increase their role
  • Training
  • Improving training for architects, engineers,
    auditors etc. to meet implementation of
    technically demanding building solutions.

EPBD and Air tightness
  • Common general framework for the calculation of
    energy performance of buildings (Annex 1)
  • The methodology shall be laid down taking into
    consideration at least the following aspects
  • (d) natural and mechanical ventilation which may
    include air-tightness
  • ...

Indoor air quality
  • Build Tight Ventilate right
  • Leaky buildings
  • Discomfort
  • Space heating/cooling
  • Deterioration
  • Too air-tight buildings
  • Sick Building Syndrome
  • Symptoms e.g. headaches, fatigue

Nearly zero energy buildings
Multiple definitions Climate, building types,
building traditions , etc.
Need Common and cross-national understanding
Example of low energy standards Passive House
Air-tightness part of integrated NZEB solution
So does ventilation!

Renovations
  • Air-tightness Ventilation to be
  • considered in renovation solutions
  • Current renovation rates 1 per year
  • Targeted renovation rates 3 per year
  • Need for large scale solutions

Some concluding remarks
  • Legal framework exists but more support is
    required for implementation
  • Importance of Build Tight Ventilate Right
  • Environmental reasons
  • Comfort reasons
  • Greater need for air-tightness and ventilation
    measures
  • NZEB
  • RENOVATIONS

BPIEs mission
  • Support the development of ambitious but
    pragmatic buildings related policies and programs
    at EU and Member State Level.
  • Drive timely and efficient implementation by
    teaming up on European and member state level
    with local authorities, communities, industrial
    players, research organisations and consumers.
  • Provide the knowledge that is necessary to
    conduct both activities successfully
