REVIVE Environmental Study

REVIVE

This study aims to provide an overview of the environmental strategy for the Revive housing project by working through the scales from masterplan to individual dwellings. The orientation of the blocks was an early massing decision to ensure each dwelling had enough access to natural sunlight throughout the year. Other design elements have been introduced to individual dwellings addressing shade, heating and ventilation to provide a comfortable and appealing place to live. Revive’s intention is to provide zero carbon homes through the encouragement of each dwelling to meet PassivHaus requirements, this will include the need for a mechanical ventilation and heat recovery system fitted in each house. Rainwater harvesting will also be used throughout the scheme where grey water will be used

The public park gets sun all year round due to the spacing and orientation of the blocks. The ‘Typical’ and ‘Back-toBack’ terraces get an even amount of sun, compared to the stacked which gets the most sun as it is south facing.

Dwelling Strategy

Rainwater Harvest Calculation

Total Roof Area = 2314.8m²

Permeable Paths Area = 4248.42m²

Total = 6563.22m² x 835 (Annual Rainfall Liverpool) x 0.8 (Drainage Coefficient) x 0.95 (Filter Coefficient)

Total = 4,165,019.41 (Litres per Annum) x 5% = 208,250.971 L (Tank Size)

Demand: 150 L x 121 (Residents) = 18,150 (Litres per day)

18,150 x 365.25 = 6,629,287.5 L

Does not meet demand The tank will be used to support the main water system, reducing water bills.

Maple Hazel Silver Birch Bees Birds

Residents can shop locally at the food market where the community sell their homemade goods.

Trees for Noise Barriers and Shade

Dotted around the scheme and in the central public park.

Outdoor Dwelling Space

Each dwelling has outdoor space, whether this is a balcony or a private garden.

Daily Watt-hours = Solar panel watts x average hours of sunlight x 75% (250 watts 5 hours x 0.75 = 937.5 daily watt hours)

937.5 ÷ 1000 = 0.937 (kWh per solar panel)

Average 1 Bed Usage = 1800 kWh

Average 2 Bed Usage = 2500 kWh

Average 3 Bed Usage = 2900 kWh (1 Bed Example)

1800 ÷ 365.25 = 4.928 (daily kWh usage)

4.928 ÷ 0.937 = 5.259 (solar panels per 1 bed) 6.845 ÷ 0.937 = 7.305 (solar panels per 2 bed) 7.940 ÷ 0.937 = 8.474 (solar panels per 3 bed)

20 (1 Bed) x 5.259 = 105.18 22 (2 Bed) x 7.305 = 160.71

10 (3 Bed) x 8.474 = 84.74

105.18 + 160.71 + 84.74 = 350.63 (Total solar panels)

North South

Photovoltaic Panels

Photovoltaic Panels will be fitted to the south facing roofs to generate energy from the sun to provide electricity for the dwellings.

The recessed balconies will allow solar shading to occur, reducing glare and hear gain in the summer. This will keep the building cool.

Smart metres will be fitted in each dwelling allowing each resident to be aware of how much energy they are consuming.

Underground pipes containing water which is compressed and released into the house at a higher temperature will heat the dwellings.

Permeable Paving

Deciduous Trees Smart Metres Ground Source Heat Pumps

The public paths will consist of a permeable surface treatment to act as a natural filtration system for water to be stored and re-used.

The community garden will give residents the opportunity to grow food together increasing interaction. The garden is also a safe space for children to play

Passivhaus Communal Recycling Bins Recessed Balconies Community Garden

Underfloor Heating and Cooling Bee Hives & Birds

Bees and birds will be attracted to the specific trees planted in the park, residents will be able to use the honey from the bees to sell.

Bin stores located near the bike storage unit will allow residents to separate their waste into the appropriate bins ready for collection.

Deciduous trees have been planted across the scheme to filter direct sunlight in the summer, attract wildlife, and provide privacy to some dwellings.

Rainwater Harvesting Tank

Reclaimed Slate Roofs

Mechanical Heat Recovery Systems

Triple Glazed Windows

Rainwater will be collected and stored in a tank to be used for domestic uses such as toilets and gardens throughout the scheme.

The scheme will achieve Passivhaus standards through outstanding energy efficient homes, eliminating the need for space heating and cooling.

The underfloor heating system will provide an evenly distributed temperature all year round whilst reducing running costs.

The roof slates will not absorb much rain water, this is to collect as much water as possible for the rainwater harvesting tank.

Warm air will be captured from outside, kitchens and bathrooms. It is then filtered through a central heat exchange unit and distributed around the house as clean air.

Triple glazed windows will be used to retain heat which will also reduce energy consumption and providing good acoustics.

Chosen Area Of Study

Rigid Insulation

The Revive housing scheme’s primary structure and load bearing walls are composed of Structural Insulated Panels (SIPs) which provide high performance characteristics; high quality insulation properties, lightweight and versatile (such as its use in wall panels, roof and flooring). The wall build ups have an extra layer of insulation to meet the PassivHaus requirements and are cladded in brick. The dwelling façades do not disrupt the surrounding area, the pale brick is an alternative approach to the typical terrace houses along Lodge Lane. This brick walls are exposed on the inside of each terrace where they are attached to another, giving the walls an interesting texture. High grade windows and doors, sourced locally, will give the scheme an opulant feel. Other details such as the charred timber cladding around the balconies and between windows add to the projects’ luxurious ethos.

Stone paving is far more attractive than concrete style paving, it is also more durable, and needs very little maintenance. This will be used for the front paths.

REVIVE - INTERIOR AND LIGHT STUDY

REVIVE Interior Study

NATURAL SUNLIGHT

This study illustrates the key interior spaces in terms of light and materiality within the ‘Stacked Terrace’ prototype. This dwelling in particular maximises the daylight which penetrates through the scheme due to the south facing frontage. The open plan ground floor allows the light to travel through the entrance hall into the dining space and kitchen. Interior materials have also been chosen to mimic the exterior, forming a coherent style to the dwellings inside and out. The exposed brick and timber panelled walls add contrast to the spaces, especially when mixed with the diverse range of finishes and furniture. These walls have been left bare, giving the residents the option to paint them if desired, whilst creating a warm, homely feel to the dwellings.
