Performance Gap | calculated vs operational data medians

US around half of buildings have more than a 25% performance gapA 2011 study analyzing the designbuild project delivery method in the United States shows designbuild was used on more than 43 percent of total construction value projects in 2004We need this feedback loop to inform design and innovation

Conclusions | Costs and risks associated with the Performance GapCapital cost of unused/underutilised equipment: Metering, BMS, sensors and controls, AHU inverters, actuators, LZCs, etc. can amount to 2-5% of capital cost

Misplaced value engineering: fabric performance and air-tightness, all openings, floor to floor heights, thermal mass, entrance lobbies, seasonal commissioning, daylighting, controls, training, manuals & log book compliance or architecture?

Increased management, maintenance and energy costs: between 15-44% of total annual energy costs could be saved amounting to potentially tens of thousands of pounds per year

Mitigation costs: ~ 50% of annual energy costs Soft Landings with energy disclosure approximately 0.1% of construction budget

Profit loss of consultants and contractors

Productivity loss for occupiers and FM

It adds up

The cost of building performance evaluations50% of our time went on gathering energy data

20% on chasing client, consultant and contractor teams for design vs as-built data

25% on analysis of the data gathered and additional energy modelling

5% on gathering occupant feedback

Targeting operational performance

New types of contracts are needed to enable data sharing from start to end

With Hattie Hartmann and Sofie PelsmakersTHANK YOU

RECOMMENDATIONSUpdate Schedule of Services & RIBA PoW overlay to better target BP

Create RIBA scopes for minimum and research BPE

Update RIBA PQQ & briefing guidance for clients, consultants, contractors

Update RIBA guidance on research in practice

Incorporate building performance methodologies in course validation

Use CarbonBuzz as a Conduit for research and expertise & to link up with other industry bodies
