10 London - Plants not Plant Cundall has completed a research project which draws on the testing of others as well as in house testing to quantify the benefits of plants. These results will be presented, and the benefits quantified in terms of energy and CO 2 reduction Plants in Buildings Better air quality Less ventilation Removes PM2.5 / PM10 Plants on Buildings SUDS Better air quality Lower temperature Less energy

11 Bucharest - What s next for green offices in Romania? The present? Legislation is in place Growing body of advocates Enforcement room for improvement Accreditation is trailing behind neighbours Projects are designed in silos. What s next? Holistic approach to building design. Productivity, health & well beings in buildings. Improved air quality & ventilation Improved daylight/ electric lighting Personal comfort vs thermal comfort Measures to improve background noise.

Case Study: Cundall Birmingham Brief Low energy office Collaborative workspace Exposed services Coordinated services Video conference enabling Shop front for our design services Conclusions Building design has changed Building, not systems, led Good examples to demonstrate how acoustics and thermal comfort can co-exist

14 Madrid LEED version 4. A big step forward for Spain LEED V4 Buildings under this tool will face the most dramatic change in the way they are designed in the 15 years in Spain The tool is adapted to new markets such as data centres, warehouses, distribution centres, mid-rise residential, etc. with dedicated compliance paths LEED V4 is available already and it will coexist with LEED 2009 until June KEY CHANGES New weightings and categories Increased emphasis in energy-20% Different compliance options for international projects ASHRAE 2010 (25% energy reduction in some cases, even more in others) More rigorous commissioning process including envelope commissioning Whole building life cycle assessment Water conservation includes process water (cooling towers) in addition to service water.

27 Operational Efficiency Focus on the total resource efficiency in operation to reduce carbon, water, ecological and cost footprint.

28 Operational Efficiency predicting impact BEHAVIOUR Operational hours, density, etc. Unregulated ICT, small power, lifts, pools etc. Building regulations SBEM regulated

29 Operational Efficiency All of the tools are being provided for regulated energy Fabric First Approach Improved lighting efficacies Improved plant efficiencies Allowable solutions Featured in Zero Carbon Hub

30 Operational Efficiency - all that glitters 12% renewable heat by % at 2012 Almost 100% biomass underused Commercial solar thermal underused Education sector installations - underused Air Source Heat Pumps Energy Saving Trust Heat pumps may not be the best option for homes using mains gas

35 Healthy Environments - A bigger picture The performance of office and school work is affected by indoor environmental conditions and by the features of buildings that influence indoor environmental conditions. Work performance may be improved from a few percent to possibly as much as 10% by providing superior indoor environmental quality (IEQ). Berkley

45 Personal Travel Planning (PTP) can have a fantastic impact on the way in which its participants travel, not only by encouraging more people to get out and about, but also by reducing the number of car trips. Active travel benefits include: Health and wellbeing; Cost savings; and Reduction in air pollution benefiting global warming.
