GROUP SUSTAINABILITY REPORT 2010 PROPERTY: REFURBISHMENT
JOHN F. KENNEDY CENTER FOR THE PERFORMING ARTS, WASHINGTON DC, USA
WSP Flack + Kurtz is providing MEP engineering services and retro-commissioning under a fi ve-year indefi nite quantity contract with John F. Kennedy Center for the Performing Arts. The center comprises 1.8 million square feet, containing seven theatres, two restaurants, nine special function rooms, fi ve public assembly areas including galleries, halls, foyers and administrative and support spaces. The initial construction budget for this project is $12 million and the project is scheduled for completion in 2014.
The contract with WSP covers studies, investigations, assessments, estimates and reports that will result in a comprehensive assessment of the mechanical, electrical and control systems at the Kennedy Center. This work will culminate in system upgrades that will improve energy effi ciency, occupant comfort, indoor air quality and equipment maintainability.
The initial focus of our work was to survey and analyse the existing building mechanical, heating and hot water, and electrical systems to develop strategies to optimise existing equipment performance and reduce the energy consumption of the facility. Annual utility bills were analysed for opportunities to reduce building energy costs. This evaluation forms the basis of a prioritised list of improvements that move the Kennedy Center towards its sustainability goals. Selected strategies have been engineered and will be implemented at the facility.

WSP SWEDEN: CONTINUOUS IMPROVEMENTS IN DOMESTIC ENERGY EFFICIENCY
WSP Sweden has numerous examples of how our expert contribution has resulted in improvement in sustainable construction and energy optimisation. This work is informed by our efforts to return to fi nished construction projects and learn from the “in-use” phase. As an example, in 2008, at the design stage of an 11-apartment housing block in Malmö, called Bygg Vesta, WSP predicted the energy demand for domestic hot water, heating and property maintenance would be 65kWh/m2. Our follow-up analysis in 2010, when the building was in use, revealed that the building was very close to this target.
On a later project, an apartment block with 59 apartments in Kajutan, Hammarby, WSP advised on the installation of a very effi cient Voltaire ventilation system with exhaust, and supply and heat recovery (at a rate of 90%). This system, combined with better insulation and energy effi cient windows, resulted in an energy use projection of

55kWhm2. In-use measurements will be available in 2011, but energy savings of 30% are expected.
Elsewhere, WSP has participated in the high-profi le Brogården project in Alingsas where 300 apartments of a 1 million home programme are being converted to Passivhaus standards. The long-term goal of the refurbishment is to halve the energy required both for heat and lighting. WSP engineers recommended the installation of a heating system with a recovery rate of 85%; solar heating and wood burners will provide energy for domestic hot water and the peak heating that will be needed for warming. Small-scale wind turbines will also be installed in the area. So far, energy consumption has been reduced from 216kWh/m2 to 94kWh/m2, with a further target of 92kWh/m2.
