Building Energy Labeling provides transparency in the energy performance of buildings, giving better information to decision makersInformed consumers should make better, rational decisions

“…However it was not only older buildings that were found to be energy inefficient. Despite opening only six years ago, London's City Hall received an E grade. City Hall was described by Foster & Partners, which designed it, as a "virtually non-polluting public building".”

Energy Labels/Ratings:
ENERGY STAR, Energy Guide, NABERS Energy
Just Energy, not other attributes like Water, IAQ, etc.
Broader Environmental Labels/Ratings:
LEED, BREEAM, CASBEE, growing number of others
May include energy ratings as one component

A Label conveys information to a consumer◦ Not technical, needs deep consumer research to
understand consumer decision making processCertification is a process ◦ Generally includes a range of technical standards
and definitions intended to set rules to keep information consistent
Disclosure requirements define what must be made public vs. confidential (perhaps between multiple parties)

“Asset” Ratings, based on calculation of how the building could optimally operate“Operational” Rating - also called a “Measured” Energy Rating - based on actual measured annual use
◦ Buildings rating well on one may not be as good on other type of rating

What does the EPBD require?
Energy Performance Certificates (EPCs) forall buildings over a size threshold; domestic and non-domestic; new and existing, when built, sold or rented outDisplay Energy Certificates (DECs) for public buildingsInspections of boilers & air conditioning systems

Ambitions of Europrosperresearch project 2002-04:
Display energy certificates based on actual energy use, not just theoretical. Transparency between expectations and outcomes. (green and yellow columns)Multiple performance indicatorsLook mirrors the EU domestic appliance label. Market research indicated this format was preferred.

Benchmarks/Ratings for both landlord performance, and tenant energy useInforming tenants of landlord performanceInforming investors of building performanceReliant on an effective tenant landlord split– Otherwise, what is tenant, what is landlord?– Model works strongly in Australia– Combined with gross leasing avoids classic
tenant/landlord split

The Danish Energy Saving Trust has implemented a web-based tool—Se-elforbrug ("watch electricity consumption")—to present data on electricity consumption in public and private buildings The website provides hour-by-hour consumption data for each facility as well as analysis reports breaking down average day, evening, and night usage and data on the past three months consumptionIndividual building data can be compared to that of other buildings within the same market sector or to all other participating buildings.

• Harmonization (harmonisation?!) is a lot harder than it sounds!! General agreement that cooperation would be useful, “as long as you do it that way I’m currently doing it”
• Need agreement that international cooperation is valuable, conceptually simple, but details challenging
• You can’t do compliance well without other enabling regulations (upstream policy)
