RUNNERS UP

5 Broadgate

Entered by: Make Architects

A remarkable environmental design ethos has produced one of the most sustainable large office buildings in the country. Swiss investment firm UBS鈥� London HQ houses 6,000 traders in 700,000ft2 of office space. A super-insulated primarily solid envelope reduces solar gain and helps the building be almost 50% more energy efficient than Part L of the 黑洞社区 Regulations.

Bartholomew Barn

Saint-Gobain

Measuring just 450m2 and costing 拢1.2m, this multipurpose hall may be one of the smallest finalists but what it lacks in size it makes up for in innovation. The Barn provides space for sports, assemblies and drama for King鈥檚 Hawford Junior School in Worcester. It uses Saint-Gobain鈥檚 Multi Comfort design concept, which includes Passivhaus standards of energy use. The concept seeks to optimise four comfort types: thermal, acoustic, air and visual, aiming to increase wellbeing while protecting the environment.

GSK Compliance 黑洞社区

Simons Group

Can a pharmaceutical facility with all its heavy plant and servicing requirements achieve carbon neutrality? On the basis of GlaxoSmithKline鈥檚 (GSK) new operational base in Ware, Hertfordshire, the answer is yes. Not only is the building carbon neutral but it releases 17 tonnes less CO2 per year than a conventionally designed pharmaceuticals building of a similar size.

Hub by Premier Inn Covent Garden

TowerEight

Hub Covent Garden is the only UK hotel to achieve BREEAM 鈥渙utstanding鈥� status. Hub is based on the 鈥渓ean, clean and green鈥� approach: it aims to use 30% less energy than required by 黑洞社区 Regulations and uses 100% renewable energy. This is achieved by initiatives such as heat recovery technology to heat and cool guest rooms, a biodiverse roof and cycle store for guests.

Keynsham Civic Centre

Max Fordham / AHR

This office building in Somerset is virtually zero carbon and on target to achieve a DEC A score at the end of its second full year of operation. It uses a hybrid cross-laminated timber frame and harnesses high quality, low maintenance natural materials such as solid oak flooring and the standing seam brass that makes such a visual impact externally.

Land Rover BAR America鈥檚 Cup HQ

HGP Architects

The America鈥檚 Cup may be the most glamorous yacht race in the world but the new Portsmouth HQ of its British race team is built from a mixture of the practical and pioneering. The 6,874m2 28m tall building provides office and training space for the crew as well as a vast triple-height workshop for boats. Environmental features include 432 solar PV panels and 100% renewable electricity.

Penarth Learning Community

HLM

The education sector may have access to smaller public funds than has been the case in the recent past but Penarth Learning Community proves that this need be no barrier to achieving sustainable design.

The project has been designed to deliver a flexible learning environment with minimal environmental impact. Features included reduced reliance on artificial lighting, natural ventilation and extensive shading devices to limit solar gain.

The Enterprise Centre, University of East Anglia

Morgan Sindall

This landmark project is the first building in the UK to be wrapped in thatched timber cassettes, combining traditional construction with modern technology. It is also the first building in the world to use Thetford Corsican Pine in its timber frame. As well as these achievements, the project was awarded BREEAM 鈥渙utstanding鈥� and Passivhaus dual certification.

University of Leicester Centre for Medicine

Willmott Dixon

The University of Leicester鈥檚 new 拢42m Centre for Medicine is the UK鈥檚 largest non-residential Passivhaus building.

It provides 12,836m2 of office, lab and teaching space over six floors within twin, podium-linked tower blocks. The building has achieved BREEAM 鈥渆xcellent鈥� and EPC A-rated dual certification. Its insulated envelope provides U-values of 0.13W/m2K and air permeability of less than 1m3/m2/hr@50Pa. Intelligent systems include automated blinds to keep rooms cool.
