phi Low Carbon also act as consultants to other architects, contractors and clients supporting their aims to achieve Passivhaus standards and low embodied carbon in construction. Our role can include.
Early design advise on built form and orientation to optimise form factor and the benefits of useful solar gain during the heating season.
Preliminary PHPP assessment to establish fabric U values.
Advice on construction options for wall, floor and roof build up to achieve U values and reduce embodied carbon.
Advice on the airtightness barrier and line within the thermal envelope to enable ease of construction and avoid interstitial condensation.
Advice on window size, configuration and shading to optimise useful solar gains during the heating season whilst limiting excessive solar gain during the summer months.
Thermal Bridge Calculations using 2D software anaylsis ( Flixo)
Strategies for Mechanical Ventilation and Heat Recovery (MVHR), Heating and Hot water to minimise energy use whilst ensuring the comfort of occupants. Detailed design by specialists.
Advice for on site renewables such as solar PV or solar hot water and the extent required to offset any overrun of the PER ( Primary Energy Renewable) Target and/or achieve the Passivhaus Plus or Passivhaus Premium standard. Detail design by specialists.
Submission of pre- construction PHPP calculations to the Passivhaus Certifier, to ensure any anomalies are addressed ahead of construction.
