National Code Provincial Regulation Municipal Enforcement Improved codes important but not sufficient do not address existing buildings code setting process “out of date” range of performance of buildings “built to code” far greater than expected
3
National Building Code – no reference to energy efficiency until 2008 Model National Energy Code - Buildings (MNECB) developed in 1997 now outdated Ontario Building Code referenced ASHRAE 90.1 in 1992/ MNECB in 1997 City of Vancouver – referenced MNECB
4
8 Ontario school boards design and performance of 68 newer schools benchmarking identified top schools building profiles/technical audits defined common characteristics and design standards workshops, design charrettes with caretakers, principals, board staff & design teams improved design for future schools and operational standards, practices for existing schools
5
Electricity Consumption - 3:1 range TRCA Sustainable Schools Program Best School
6
Natural Gas - 4:1 range TRCA Sustainable Schools program Best School
7
Water - 5:1 range TRCA Sustainable Schools program Best School
8
Sustainable Schools Program Sharing benchmark information inspired significant savings and ongoing improved practices Design charettes led to design improvements and performance targets for new schools
9
Current Codes are far behind best practice
10
Codes not enforced Designers are not owners Designer never pay an energy bill! Systems not commissioned; recommissioned “Lowest First Cost” not “Life Cycle Cost” e.g. electric baseboard heaters Conventional Design Process Disconnects between: Architecture – Engineering – Construction – Commissioning – Operations – Maintenance No recognition of impact of occupants, custodians, maintenance procedures
11
Accountability Framework benchmarking to establish energy performance standards for each building type ongoing target-setting for individual buildings, portfolios monitoring and reporting to all stakeholders on progress towards targets verified and $ savings delivered continuous improvement
12
Occupants Occupant engagement and recognition education and support measurement and reporting Technology/Retrofit Design Building operations Occupant behaviour Building Performance Audits should be used for all retrofit projects Operations benchmarking operational best practice targets and reporting training Action Plan
13
Allows building owners/managers to: continuously assess and improve building performance – accessible, on-line system, inexpensive improvements include operational and scheduling potential to pool $savings for managed capital improvements allows building owners to work towards LEED certification Uses integrated system of tools, performance standards, resources and information Delivers staff training and best practices Engineering only needed for major projects Improved specifications for conservation projects Links to “Green” Procurement Engages Occupants
14
Assessment of performance, including carbon footprint and conservation potential Data management and national (or international) benchmarking (building performance database) Audit templates and performance standards Multi-year template for planning actions and tracking improvements Ongoing measurement and verification
15
Commercial buildings: 3,000,000 m2 (60 buildings) School boards: over 250 K-12 schools Administration buildings: 1,000,000 m2 (75 buildings) National representation
18
Even professional facility managers of Class A buildings found significant savings.
20
Ontario cannot rely on traditional conservation programming e.g., incentive/bulb; estimated savings – fools paradise – $ spent; are savings real? gas DSM has always had strong role for performance improvement – boiler optimization; electric conservation – more about changing products Conservation not “one shot” intervention – continuous improvement long term, managed approach - better market for Ontario technologies, employment makes conservation ongoing basis for cost savings Green Building Performance System should be used for all ratepayer funded programs: Measures real savings Addresses all energy forms and water Flexible: consistency for LDCs - respects regional/fuel differences – weather normalized ◦ Linked to climate change
