of environmental design, with particular emphasis on sustainability and the use of renewable energy,
Work with clients and architects from the earliest stages of a project, enable design choices to be made from first principles, outlining alternative energy strategies and quantify the benefits to be gained from different approaches to siting and structure.
The interest in renewable energy is focused on building integrated photovoltaics; this is considered to have an enormous impact on building design and the economics of energy use. Whitbybird also work on module integration and energy autonomy, management and distribution. The technology is developing fast and clearly demonstrates benefits available by replacing conventional cladding materials on roofs and facades,
In producing energy conscious, low pollutant design concepts and details for the theatre Whitbybird are fully aware of life cycle costing issues. The economics of a building project will always be as significant as its efficiency, safety and comfort. This work is helping to demonstrate that an environmentally conscious design can represent long term value in changing markets.
The main energy efficiency measures utilised include a high efficiency thermal wheel to recover heat from expelled air and the use of wind catchers for natural ventilation and free cooling in the foyer space.
Displacement ventilation is used in the auditorium and large meeting room to provide free cooling and heat recovery is used where possible.
The glazed foyer also exploits winter solar gains and daylighting. Auditorium and Large Meeting Room ventilation, heating and cooling Displacement ventilation used to provide free cooling and reduce air conditioning requirements Occupancy, air quality and temperature sensors fitted to reduce or stop ventilation as required High efficiency (<1 W/l/s), variable speed fans Use of thermal wheel, with efficiencies of up to 75%, to greatly reduce heating and cooling loads General ventilation, heating and cooling Natural ventilation used wherever possible. Where mechanical ventilation is used, low speed, high efficiency fans are specified (< 2W/l/s) Heat recovery using recuperators for mechanical ventilation, efficiencies up to 50%
Foyer ventilated and cooled using roof mounted wind catchers Underfloor heating specified to utilise thermal mass, increase efficiency and reduce peak loading Systems Modulating gas burners with low NOx emissions Increased chiller coefficient of performance (COP) by using higher water temperature and electric expansion valve High efficiency (95%+) condensing boilers (with improved efficiency due to use of underfloor heating) Direct feed gas water heaters for kitchen

Controls

Optimised heating control with system zoned to suit different uses Variable temperature system with weather compensation to increase controllability and improve boiler condensation efficiency Variable speed chilled water pumps Variable speed heating pumps
