Develop a software model and commercial service for optimising internal building conditions to improve productivity by at least 10%, reduce energy use by 30%, and improve occupant comfort and wellbeing.

Objectives are to:

• Empirically validate the link between IEQ and staff productivity

• Test the solution in a number of trial commercial buildings

• Develop a software-based supervisory control and reporting solution operating in a cloud environment

Project aim

• Innovate UK competition – Building whole-life performance

• Project value: £530,000 part funded by Innovate UK and EPSRC

• Project duration – 24 months from 1 Feb 2016

• Project lead – LCMB

• Academic lead: Oxford Brookes University

• Research conducted in commercial office buildings provided by Argent, Emcor and Kings College

• BCO and CE to lead on industry exploitation and dissemination

Findings: impact on productivity and cost

1 Allen et al(2015)

USA Intervention in climate chamber(24 subjects)

CO2 - 550ppm, 945ppm, 1400ppmVOC – low and high (increase by 0.5mg/m3)

21% decrease with 400ppm increase in CO2

13% decrease with 0.5mg/m3

increase in TVOCs

2 Park & Yoon(2011)

Korea Intervention in climate chamber(24 subjects)

Ventilation:5, 10, 20l/s/person

2.5 - 5% increase when ventilation is increased from 5 to 20l/s/person

3 Wittersehet al (2002)

Denmark Intervention in offices(30 subjects)

Temperature: 22°C, 26°C, 30°CNoise: 35dBA, 55dBA

3% decrease in 55dBA 55% more mistakes in 30°C

5 Fisk et al(2002), Federspielet al (2002)

USA Observational(3 months in a call centre)

Ventilation rate:CO2 as proxyTemperatureManagement

16% decrease at temp > 25.4°CLowest call handling time when indoor CO2 is up to 75ppm higher than outdoor CO2

USA Observational(40 buildings)

Ventilation:rated as moderate or high

Sick leave associated with moderate ventilation rate

Ventilation:8, 10, 15l/s/person

0.91% increase with 7l/s/person increase (8-15l/s/person)$38b annual saving 7l/s/person increase

Meta-analysis of existing datasets

(Innovate UK BPE programme:

non-domestic buildings)

Non-domestic BPE study

• Innovate UK BPE programme 2010-2015

• Case study buildings (domestic and non-

domestic) designed to low energy

performance. 101 project out of which 47

non-domestic projects.

• Non-domestic buildings include education,

offices, public service and culture

• Meta-analysis in WLP+ included projects

where data on building performance were

available

• Focus on fabric performance, energy

consumption, environmental performance

and occupant feedback and satisfaction

Non-domestic BPE study:Office spaces (n=21)

• 21 out of 47 projects were in

offices

• High level of insulation in the

buildings

• Floor area: 705 – 37,000m2

• BUS surveys conducted in all

buildings

• 45 – 5,250 occupants

• In 12 out of 21 projects,

perceived productivity

increased by an average of

4.9% and maximum of 10%

• Over 5000 occupants

• Personal controls for

lighting and HVAC

• 5% increase in perceived

productivity

• Excellent BREEAM rating

• Good daylighting and

natural ventilation using

BMS-controlled louvers

• 5% increase in perceived

productivity

• Ground source heat pump and

Solar PV systems Exemplary

for low carbon emissions

• 10% increase in perceived

productivity

Baseline Testing

EMCOR Facility

• Two identical spaces on two floors suitable for control and intervention studies

• Sensors installed to record temperature, CO2, RH, noise, light intensity and other indoor and external environmental factors

• Energy data also recorded

• Data collected through the BMS and using on-site data loggers

King’s College London

• Waterloo Campus next to a busy roundabout and a busy train station (~ 150m)

• Spaces identified for control and intervention studies

• Interesting environment for studying the impact of natural ventilation and air quality
