There are many great good practice examples of green buildings in Islington, far too many to include here. Below is a small non-exhaustive selection highlighting the range of projects completed across Islington. Links are provided to websites with further information.
See also this interactive map which shows the locations of many of the buildings listed below along with summary details.
Ashmount Primary School and Bowlers Nursery (Islington Council)
This scheme is a negative carbon development. Energy efficiency was maximised by optimising form, maximising the insulation and the amount of exposed thermal mass and designing for daylight and natural ventilation. To service the remaining energy demand in the lowest carbon manner, the best solution was found to be to host a community energy centre (CHP and biomass) on the school site, designed to provide all the heating and some of the electricity for the site and the existing adjacent residential block, Coleman Mansions. The proposed energy centre will reduce the carbon footprint of the school site by 50%. By supplying heat to Coleman Mansions, the development will actually be carbon negative - that is to say the scheme will save more carbon by providing a more efficient energy supply to Coleman Mansions than is used on the school site. Wider sustainable design features include use of low impact materials and ecological enhancement across the entire site. The project was awarded £500k through the Department for Children, Schools and Families Low and Zero Carbon Schools Exemplars initiative. It is accredited BREEAM ‘Outstanding’ (design stage) and was a BREEAM Awards 2012 Winner. For more information see the downloadable 'Ashmount school' file at the bottom of the page.
Mayville Community Centre (Bere:architects)
The Mayville Community Centre, completed in August 2011, is the first fully certified Passivhaus retrofit community centre in the UK. It is designed to use over 90% less energy than before renovation, dramatically reducing energy bills whilst creating excellent comfort conditions in both summer and winter. Renovation concentrated on a fabric first approach to energy reduction, retaining the existing brick walls and wrapping them, the floors and the roof, in external insulation, installing triple glazed windows to ensure net heat gains even throughout winter, a low-energy heat recovery ventilation unit and a ground source heat pump. A solar PV array and solar thermal panel supply electricity and hot water and rainwater harvesting tanks collect rainwater for WC flushing and garden irrigation. The Mayville project demonstrates how a medium sized Victorian solid masonry building, a common building typology, can be refurbished to achieve energy consumption reductions to exceed current UK building regulation standards, the lesser Passivhaus Enerfit standard (for refurbishment) and even the UK’s 2019 targets for non-domestic buildings. The total cost of the improvements was £1.6m; the project was 100% funded by grant aid and by two generous local benefactors who chose to remain anonymous.

Ironmonger Row Baths (Islington Council)
Extensive refurbishment work on Ironmonger Row Baths, originally constructed in 1931, is currently underway (Spring 2012) to provide an integrated space fit for a 21st century public leisure service. The refurbishment has been designed to maximise energy efficiency, including through the use of: thermal insulation to the internal face of external walls; replacement of single glazing with double/triple glazing; reduced air leakage; natural ventilation to augment mechanical means; maximisation of daylighting; high efficiency lighting throughout; and high efficiency gas condensing boilers. Ironmonger Row Baths will also benefit from heat provided from an off-site combined heat and power (CHP) plant via a district heating system. The scheme was awarded a BREEAM design stage rating of ‘Excellent’ in December 2010. For further details please see the 'Ironmonger Row Baths refurbishment' pdf at the bottom of this page.
24 Britton Street (Archer Architects and Levolux for Great Portland Estates)
This £3.7m refurbishment project involved the transformation of an existing 40,000 sq ft office building of significant architectural character to create more flexible and comfortable office accommodation whilst improving the environmental performance of the building. Works included the addition of a striking new external solar shading solution (which includes tubular louvres, plus automatic roller blinds at fifth floor level) to significantly reduce solar heat gain and glare whilst maximising daylight levels and providing occupants with good outward visibility. The louvres are finished in an eye-catching and highly durable bright red gloss powder coating, selected following consultation with the council to complement the black and red colour scheme running throughout the building. Also added was a new entrance pavilion, atrium and reception facility and an improved cooling system. The refurbished building has achieved a BREEAM ‘Very Good’ rating, indicating a big step forward from the original 1970’s design which suffered from extreme problems of overheating during the summer months. The shoe retailer Kurt Geiger has agreed a pre-let of the property as its new headquarters. For images of the building see London Festival of Architecture.
The Ecology Centre, Drayton Park (Islington Council)
This Islington Council building, set within the Gillespie Park Nature Reserve, benefits from onsite wind, biomass and solar thermal renewable energy generation systems allowing it to minimise carbon emissions from its use. Other key features include use of European softwood from sustainable sources, water saving features and recycling of waste water through a reed bed system. The Ecology Centre is used to deliver educational and community events and teach children and adults about local biodiversity and sustainable practices. For more information see the Council's Ecology Centre webpage.
The Muse, Newington Green (Bere:architects)
This is a super-insulated ecological house and architectural office designed and owned by architect Justin Bere. Triple glazing and low energy ventilation with heat recovery, together with very high fabric insulation standards, means very little additional heating is required in winter and, with external blinds, the house remains cool in summer. Other features include solar thermal for hot water, solar PV panels, rainwater recycling, biodiverse green roofs supporting a range of native species including native hawthorn trees, bat boxes, stag beetle sandpits, a thriving bee hive and even a bumble bee sleeping quarter! Designed to be warm in winter and cool in summer whilst using very little energy, the Passivhaus standard is gaining increasing attention in the UK but this scheme was an early pioneer. For more information see Justin Bere's website.
Ropemaker, Ropemaker St (Arup Associates, for British Land)
A development on the edge of the City, Ropemaker is a 20 storey office building providing 593,000 sq ft (55,000m2) of space. Sustainability is central to the building’s design, demonstrating that offices do not have to be energy guzzling glass boxes requiring high levels of air conditioning. A highly visible feature of Ropemaker is the double glazed cladding which is tilted away from the sun’s path to reduce the energy required for cooling by up to 30%. Other features include use of renewable energy technologies - solar thermal panels, solar photovoltaics (PV) and a biomass boiler; a large rainwater harvesting system; green roofs covering 60% of available space; use of recycled materials; and 270 bike racks with lockers and shower facilities. Ropemaker has a BREEAM ‘Excellent’ rating, won the Estates Gazette Green Award for Office Development of the Year. For more information see the Ropemaker Place website.
Highbury Grove school, Highbury New Park (BDP, for Transform Islington)
This school achieved ‘Highly Commended’ in the ‘Most Sustainable School Design’ category of the 2008 ‘Excellence in Building Schools for the Future Awards’. It has also achieved an ‘Excellent’ BREEAM (British Research Establishment Environmental Assessment Method) sustainable building rating. Low energy consumption and low carbon energy are at the core of the school’s design, which reduces CO2 emissions by twenty per cent (compared to 2006 Building Regulations) using a range of technologies including combined heat and power for highly efficient heat and electricity generation, biodiverse green roofs and solar shading to prevent the sun from excessively heating the building in summer. Water saving devices have been incorporated into the schools' design, including rainwater harvesting from the roof for use in toilet flushing and site irrigation. Pupils can watch digital displays that monitor the energy generated on site. For more information see the two downloadable 'Highbury Grove school' files at the bottom of this page.
Renovated Victorian Eco-home, Aubert Park (United House, for Islington Council)
This ground floor flat in a typical Victorian terrace has been renovated into an eco-home. After detailed survey and analysis, 24 measures for improving the sustainability of the property were selected and each was assessed for its installed cost and for its carbon saving effectiveness. The best measures were found to be installation of low energy lighting throughout, draught proofing of windows, cracks/gaps and chimney, insulation of external walls, and incorporation of a high efficiency boiler. A rainwater harvesting system to flush the WC was also installed, with excess water used to irrigate the garden. United House won the Green Buildings category of the Giant Green Business Awards 2010. For more information see the United House website.
Angel Building (Allford Hall Monaghan Morris, for Derwent London)
The Angel Building, an office and retail scheme, is the re-invention of an unloved early 1980s commercial building. The existing concrete frame of the old building was reused (saving the energy and waste associated with demolition and rebuilding) and re-wrapped with a highly energy efficient glazed skin. Key sustainability features include two biomass boilers which provide 50% of the heating demand, fritted glazing to reduce solar gains, good insulation, a displacement ventilation system, and low energy lifts manufactured from recyclable materials. Secure cycle storage, showers and locker rooms are provided to encourage staff to cycle. The Angel Building is on target to achieve an ‘Excellent’ BREEAM rating. It was also shortlisted for Islington’s Giant Green Business Awards 2010. For further information see the Angel Building website.
John Thompson & Partners Office, Great Sutton St (John Thompson & Partners)
This 1920s warehouse was renovated to maximise sustainability within the layout and encourage sustainable practices amongst its staff. The office is retrofitted with photovoltaic panels which double as brise soleil to minimise summer solar gain, solar-thermal panels to pre-heat hot water and innovative phase change materials to absorb daytime temperature gains. These measures are complemented by the use of natural ventilation through high level windows with specially fitted handles and winders and passive stack ventilation through the main staircase as well as the maximisation of the use of natural light. Green materials include natural insulation (e.g. sheep’s wool) and worktops manufactured from recycled plastic sheets derived from yoghurt pots. Secure cycle storage and the provision of showers, lockers and towels encourage staff to cycle to work. Other features include grey water collection in the showers to recycle water for WCs, and water efficient fixtures and fittings. For more information see John Thompson and Partners’ website.
Nash Terrace, Aubert Park (4orm)
This four storied row of terraced houses, designed to the German Passivhaus standard, includes triple glazing, high levels of insulation with 200mm recycled newsprint to walls, insulation to roofs, whole house ventilation with heat recovery and ground source heat pumps providing heating and hot water. Large windows allow good quality natural lighting during the day and LED low energy light fittings are used throughout the development. Venetian blinds reduce solar gain and along with the ventilation system, summertime overheating is expected to be minimised providing exceptional levels of comfort and climate change proofing. The cost of heating is estimated to be approximately £80 per year - less than the cost of a cappuccino per week. Each house also has rainwater harvesting that feeds WCs and laundry. For more information see this case study on CuttingtheCarbon.
The Gower School, Cynthia St (Architype, for The Gower School)
A suite of derelict buildings was transformed into this Montessori primary school. Its low energy design is built entirely from sustainable materials and enables users to monitor their energy use. Key features include high levels of insulation, light wells and windows carved into the existing structure and a green roof that improves thermal performance, enhances biodiversity and attenuates rainwater run-off. Sustainable materials have been used throughout including a sustainably sourced timber frame structure, recycled wood fibre boards infilled with sheep’s wool insulation, sustainably sourced bamboo floors and organic paints. Existing materials were re-used wherever possible. Other features include spray taps and low energy light fittings. These physical aspects of the building are complemented by activities encouraging environmentally sustainable behaviour amongst staff, students and parents. This building was shortlisted for Islington’s Giant Green Business Awards 2010. For more information see Architype’s website.
