Environmental Sustainability

The Dunedin Mews development has been independently assessed after completion by Stroma and certified as achieving Level 3 of the Code for Sustainable Homes. To view a copy of the certification click here.

In order to achieve Level 3 of the Code for Sustainable Homes every element of the development  has been considered from a Sustainable point of view. Below are a selection of the environmental features of the project.

Modern Method of Construction – Amvic ICF

Amvic ICF BlockThe building structure is built using a Modern Method of Construction known as Insulating Concrete Formwork (ICF). For this development we are working with industry leading ICF Manufacturer, Amvic Wall Systems. The Amvic ICF building system is based on large, hollow, lightweight polystyrene forms that interlock together without glue or mortar to provide a formwork system into which concrete is poured. Once set, the concrete becomes a high strength, air-tight structure. The polystyrene remains in place as insulation, and is clad outside and inside with the chosen finishes. Once finished, the AMVIC structure offers higher levels of occupant comfort and lower running costs for the lifetime of the building.

The Amvic ICF Structure helps to contribute towards the thermal efficiency and subsequently reduced CO2 Emissions for the building achieving one of the mandatory elements of Code Level 3.

The Amvic Insulating Concrete Formwork system has been awarded an A+ by the BRE under its Green Guide to Specification assessment scheme.

The Amvic ICF System provides

  • Energy RatingSuperior thermal performance – U-values from 0.24 to 0.22 W/m2K and intrinsic air-tightness of poured concrete helps reduce heating requirements
  • High thermal mass – the solid concrete core can store more excess heat energy for release back into the building later than lightweight construction
  • Waste and recycling – minimal waste during construction and the waste materials can either be recycled or re-used.
  • Less demand on the transport system – the polystyrene is lightweight reducing transport loads, and the ready mixed concrete is sourced locally reducing travel distances to site
  • No HCFCs or CFCs used in production

Ecological Value

The development will score maximum points for it’s Ecological impact and value. The original brownfield site which was dominated by hard standing with residential garages had a low ecological value.  The new scheme includes Landscaped Grounds and a Green Roof which will help contribute to a major enhancement in the Ecological value of the site.

The new landscaped grounds will include a minimum of 20% new planted species that are either native or with a known benefit to wildlife. The Green ‘living’ roof  will create a natural habitat for flora and insects– creating a local ecology in which the vegetation will establish and provide a home for aphids and invertebrates. It will also aid biodiversity by providing a healthy habitat in a place that could otherwise be empty providing support for the natural colonisation of locally arising plants, birds and small animals, encouraging a wider spread of species in the area.

Energy Efficient Lighting and Appliances

All of the appliances will meet the Energy Efficiency requirements for Level 3 of the Code for Sustainable Homes, for example Fridge Freezers will be A+ rated. Also 100% of the internal and external lighting will be energy efficient fittings again scoring maximum points for this section of the code.

All of the recessed down-lights in the development are the award winning Halers EvoLED. The innovative and energy efficient LED luminaire design offers a far more efficient alternative to halogen lamps. Based on calculations provided by the manufacturer, over a 5 year period, each apartment could save 5,464kg of Co2 and £1,240 in energy costs by having EvoLED downlighters installed rather than Halogen lamps.

Waste & Recycling

ProwasteThe development will provide sufficient re-cycling facilities for future residents, including a 30 litre internal bin for recycling materials in each kitchen and an external communal bin store to house a dedicated recycling bin provided by the local council.

We also ensure that all Construction Waste is managed appropriately and wherever possible waste material will be recycled. Working with ProWaste Management we have a Site Waste Management Plan which identifies the different waste streams and includes targets and monitoring of all waste, including what percentage is recycled. At all points diverting waste from landfill is the primary objective. Fortunately the construction method, Amvic ICF, means that virtually all waste from the main construction process can either be recycled or even re-used by the manufacturer.

Water Consumption

In order to comply with the Code for Sustainable Homes Level 3 the design of the internal water systems, bathrooms and kitchens ensures that typical average consumption is less than 105 litres per day. There is also an external water-butt to collect rainwater for use on the landscaped grounds.



Mechanical Ventilation and Heat Recovery

Each apartment has a dedicated Nilan VP 18 active heat recovery unit for extracting hot, humid air from kitchens, bathrooms and cloakrooms. Dust particles, moisture and smells are thus removed from the dwelling, ensuring a comfortable indoor climate.

The energy recovered from the extracted air is used to provide domestic hot water and to heat the incoming air. The VP 18 also has a cooling system, allowing the unit to cool the incoming air. The energy contained in the incoming air is utilised for water heating before the cooled air is used to ventilate the dwelling. “Free” air cooling is thus provided whenever the water requires heating.

This system works particularly well in a building constructed using Amvic ICF which by it’s nature is very thermally efficient and air tight enabling the ventilation and heat recovery system to work efficiently. The end benefit of such a system is a comfortable living environment with fresh air ventilation and stale air extraction with lower running costs than a traditional central heating system.

100% Electricity from Renewable Sources

The Electricity supplier for Dunedin Mews is Good Energy who is the UK’s only dedicated 100% renewable electricity supplier. While all other electricity suppliers rely on electricity generated using fossil fuels and nuclear power, Good Energy remains the only one whose electricity fuel mix is 100% renewable – from wind, small hydro, solar and sustainable biomass.

Use of Sustainable Timber and Wood

All of the site timber is supplied by Travis Perkins who are registered under both the FSC (Forestry Stewardship Council) and PEFC (Programme for the Endorsement of Forest Certification) Schemes which ensures that all wood is sourced from legal and sustainably managed forests.

The hard wooden flooring and kitchen worktops are all made from Bamboo rather than traditional hard woods. Bamboo is an environmentally friendly, renewable resource that has been used as a construction material for thousands of years. Ecologically, the harvesting of bamboo does not affect the world’s already dwindling timber resources. Technically considered a grass, bamboo has the ability to grow to maturity in 4-6 years. The intricate root system remains unharmed upon harvesting and allows for sustainable future growth. Using bamboo is a natural alternative to traditional hardwood flooring while at the same time doing something good for the environment.
