• Welcome to Johns Slater and Haward

    Chartered Designers of Mechanical and Electrical Systems in Buildings 


    Our Associate Director Paul Bird is the winner of the 2018 CIBSE East Anglia Engineering Excellence Award for the new purpose-built office facility for Suffolk County Council and Waveney District Council at Riverside Road, Lowestoft. 

    The Project aim was to provide an environment for both Councils to conduct their business in a building that set a standard for occupant satisfaction and environmental performance; reducing both running costs and their carbon footprint. 

    The energy efficient building was designed based on the principles of ‘passivhaus’. Key features included Actimass (Termodeck) Thermal Mass heating and cooling, ground and air source heat pumps, photovoltaics and rainwater harvesting.
