Maggie’s Yorkshire is a cancer care centre at St James’s University Hospital in Leeds, designed as a group of large planters rising out of the hospital’s last remaining green plot and using the restorative effect of contact with nature.

The Enterprise centre is a university building that aims to encourage new sustainable businesses coming out of its academic research programme; the building itself is a suitable reflection of the values and ambitions of the university and the activities of The Enterprise centre.

Airtightness goes hand-in hand with a well-insulated building envelope and is the basis for a ’fabric first’ approach to designing low-energy buildings. Airtight buildings are comfortable environments free from unwanted draughts from gaps and cracks in the building fabric that cause heat loss and discomfort. Airtightness is achieved by good detailing and construction quality through the creation of a continuous air barrier with monolithic construction of airtight materials or with airtightness membranes and by taping all joints and by overlapping and taping membranes at junctions. To ensure good indoor air quality (IAQ), continuous, controlled background ventilaton is needed (e.g. MVHR) and careful specification of materials that do not offgas and cause health issues.
