Environmental Consideration

Garden - Vibrant and diverse garden creates a view and engages senses. - Mixture of perennials, winter flowering cherry and grasses maintains garden throughout winter. - Some deciduous trees to increase solar gain in winter.
Pond and Wildlife - Helps to naturally cool - Increases biodiversity - Water has a calming, tranquil sense which helps the wellbeing of occupants. - Nectar-rich plants and bird feeders encourage wild-life

Green Roof - Individual private gardens. - Creates ecology in otherwise derelict space. - Helps wider spread of biodiversity. - Retains large portion of rainfall, reducing flood risks. - Improves air quality for patients and staff. - Reduces carbon footprint as it improves insulation of the building.
Solar Shading - Velux awning blinds reduce solar heat gain by up to 75% while maintain views out. - Brise Soleil deflects direct summer sun, improving thermal comfort.
Skylight – Improve daylight in the corridor/nurse’s station/breakout space. – Opening windows means rising heat can exit building, reducing mechanical intervention.
Glazing - Double glazing in garden rooms allows for solar gain but doesn’t lose excessive heat in winter. - Patient room glazing has TVis of 40% with triple glazing to reduce glare and increase thermal comfort.
Garden room - Biophilic design increases connection to nature, improving wellbeing. - Increases the solar gain of the building. - Open to heat rest of the building. - Close it off and opening the windows to prevent overheating.
North Facing Windows - Create views out - High windows add privacy and natural daylight. - Vents and windows improve cross ventilation
