Car showroom is a model of energy efficiency

Honda
The services design by Cunnington Clark for this new Honda showroom in Romford uses 31% less energy than the current baseline planning requirement.
A BREEAM standard of ‘very good’ has been achieved for the new 600 m22 Honda car showroom in Romford with a services design by local consultancy Cunnington Clark. The practice was contracted at an early stage to design and model a low-carbon building that would also meet the council’s target of 10% renewable energy, which has been achieved using a ground-source heat pump. Dean Barker of Cunnington Clark explains, ‘The overall scheme has been to design to lower energy use and carbon emissions below those of equivalent showroom buildings. The building design and materials used exceed Building Regulation requirements. Showroom glazing, for example, incorporates external solar shading to reduce the effect of high temperatures during summer months, while giving the building a distinctive appearance.’ The design shows an energy saving of 31% and carbon emissions 18% less than the current baseline planning requirement. Natural ventilation maintains a comfortable environment while using very little energy. This system uses wind pressure and temperature difference to draw air through the showroom and create a comfortable environment. The automated system opens the vents during the evenings of warm summer months to pre-cool the building. The vents open or close depending on the temperature and air quality inside and outside. Heating is provided by a ground-source heat pump with boreholes and an underfloor heating system. The same system can use cool water in the summer help reduce the internal temperature. There is also a solar thermal DHW system and rainwater harvesting system that collects water from the roof for washing cars.
