- - - - Mechanical - Install a Mechanical Heat Recovery Ventilation (MHRV) system during the construction of the house
      - Natural – ensure that all rooms have glazed manual openings so that air can naturally circulate
        bringing in fresh air from the outside and removing stale moist air from the inside
      - A MHRV system works by providing a constant
        supply of fresh, warm air into the residence while also extracting the inherent heat from the
        warm, moist stale air from rooms within the house having a high moisture and odour content
        – kitchen, bathroom, and utility space
      - Improves indoor air quality for occupants
      - The MHRV system must be capable of yearround operation
      - 95% of the heat contained in this stale warm air is extracted and used to heat the entering cold
        fresh air that passes through the heat exchanger without the two air flows ever mixing
      - The incoming fresh, warm air passes through a “particle filter” which stops and traps all pollen and
        dust – allowing only clean, fresh heated air into the dwelling
      - A MHRV system guarantees a constant supply of fresh warm air free of contaminants throughout
        the dwelling achieving a high-quality fresh air supply to all occupants
      - This provides high quality, clean air supply to all occupants but especially to those with underlying
        medical (respiratory) issues.
    - - Use high quality insulation to ensure the building envelope meets the current building standards and maintains a high level of thermal comfort for the occupants
      - Install of high-performance glazing / door systems in external envelope which will minimise heat loss and retain airtightness
      - Less heat loss through the windows will reduce operation energy usage
      - Adequate glazing systems on the southern, eastern and western elevations to increase solar gain
      - Maintain a constant temperature in living areas of 20 ⁰C and 18 ⁰C in sleeping areas
      - Incorporate overhangs into the design to prevent glare and overheating internally – extended roof overhangs, brise soleil, shutters, dynamic glass, pergola, etc.
      - Plant deciduous trees in the garden along the south façade - the leaves will provide natural shade
        during the summer so that the internal spaces do not overheat
      - Install a Mechanical Heat Recovery Ventilation (MHRV) system during the construction of the
        house to regulate the temperature internally
      - Install thermostats in each room to meet the needs of the occupants
      - Appropriate air barrier membrane installed to the inside of timber frame wall, keeps cold air out
        and warm air in – improving thermal environment of the home
      - • Open plan layout in living spaces enable the transfer of heat – maintaining a comfortable 20 ⁰C.
    - - Multifunctional rooms - provide spaces where people can talk and interact with each other in the one space while carrying out day to day tasks - e.g. having the table in the kitchen space so people can be eating/doing homework while chatting to those preparing food or cooking
      - Incorporate seating areas into the kitchen space so that people are not isolated in separate rooms - this can be done through window seats, counter seats, tables etc.
      - • Have separate quieter spaces so the occupants can be removed
        from noise and activity if they want to relax
      - Open plan living is very popular – it is important to be able to perhaps close off these open plan spaces too into separate smaller units – use of pocket doors
      - Outdoor living spaces for social gatherings during
        milder weather
      - Separate living / social space for small groupings interactions such as living room, snug or outdoor living space
      - Large areas of glazing / natural light /with views
        out to a green landscaped area/garden
      - Comfortable seating beside windows and sound
        proofed from vehicular traffic/noise
      - Sunspace easily accessible and with comfortable seating
  - - - • The design of a house has a huge impact on the mental health and wellbeing of the occupants
      - • Reduces stress levels for occupants of the house
      - • Provides a calm, secure, private space for occupants – better for health and wellbeing
      - • Adequate natural light encourages occupants to appreciate nature - improved wellbeing
      - • Natural light enhances occupants comfort level and enables a positive mental attitude
      - • Natural light enhances colour definition and seasonal changes perceptible
      - • Plentiful fresh air invigorates occupants - good for health and wellbeing
      - • Being surrounded by nature reduces stress and improves mental health - connect the indoor and outdoor spaces with large glazing and opening doors out to the garden them a sense of place and belonging
      - • Opening windows so the sound of nature can be heard inside calms the occupants
      - • Using materials that are locally sources helps to link the occupants with their community giving
      - • Designing a space with good air and thermal quality can be both comforting and refreshing
      - • Improves and encourages sound sleeping - essential for rest and wellbeing
      - • Combinations of biophilic design, natural light and sound proofing will lead to improved wellbeing.
- - - - • The use of photovoltaic panels reduces the use of
        electricity and finite materials required to produce it
      - The generation of electricity with PV panels would
        reduce carbon emissions from the house
      - Panel installed on a south facing inclined surface
        – roof surface
      - Panel will reduce the operating costs and negative
        impacts on the environment.
    - - Reduces the demand on the houses heating system
        – reduces energy use
      - Efficient method of heating hot water for domestic
        use by using the power of the sun
      - To reduce the dependency on mains electricity and operational carbon of the house
      - Installed closest to south-facing aspect for maximum efficiency to heat domestic hot water.
    - - The installation of a MHRV system will recover up
        to 95% of the heat that is normally lost
      - Reduce the demand for additional heating energy usage
      - The system maximises the energy input for a house- assists maximise energy usage
      - Improves indoor air quality for occupants.
    - - Air-to-water heat pumps extract heat energy
        from the outside air to heat a house
      - Low carbon footprint as the system does not burn any fossil fuels
      - Easily installed or retrofitted into a domestic house
      - The external unit extracts the air and the internal unit exchanges this air to heat the house.
      - Very energy efficient method of heating spaces and hot water in a house
