Vilallobent

Description

Passivhaus consultancy and M&E engineering design for a single-family home, certified Passivhaus Classic, built with renewable bio-based materials, including a cross laminated timber structure (used as the airtight layer), wood fibre insulation, and timber window frames.

Passivhaus consultancy included PHPP energy simulation and performance optimisation, thermal envelope design, passive strategies to combat summer overheating and thermal bridge calculations.

HVAC design included heating and DHW production with an air-source heat pump and underfloor heating system, with ducted mechanical ventilation with heat recovery. All services were integrated and controlled with Loxone home automation system. Energy certification and compliance verification with the Spanish Building Regulations CTE HE0 & HE1 was carried out, achieving a class “A” certification.

Shirehampton

Description

These 7 terraced homes constitute the world’s first commercially available straw eco-homes. Behind the traditional brick elevation of the development is a state of the art, well insulated, prefabricated, low-carbon straw bale construction system: the BM Trada Q Mark certified ModCell Core system.

The homes include individual Passivhaus certified Mechanical Ventilation with Heat Recovery (MVHR) units for good indoor air quality and minimal energy loss. Thermal comfort is provided through high levels of thermal insulation, double-glazed argon-filled low-e windows with “warm edge” spacers between the glazing and PVC frames, reduced thermal bridges, and reduced air leakage through the envelope. Individual air source heat pump units provide space heating and hot water generation. Each home is fitted with a 2.2 kWp grid-tied solar PV array, A++ appliances and broad-spectrum LED lighting.

Passivhaus consultancy included PHPP energy simulation and performance optimisation, and thermal envelope design. M&E engineering included heating and DHW production with an air-source heat pump, together with ducted mechanical ventilation with heat recovery.

HQ1

Description

Passivhaus consultancy and M & E engineering design for the deep retrofit of a single-family home, certified to Passivhaus EnerPHit Component Method, and VERDE. Healthy bio-based materials have been used as far as possible, including sprayed cellulose internal wall insulation, clay boards for dry lining (instead of gypsum plasterboard), and clay paints. The extension, built on the top floor of the house, is made of prefabricated lightweight timber-frame panels with wood fibre insulation. The final “Blower Door” airtightness test achieved N50 = 0.99 ach. Construction details were looked at in detail during design phase to reduce and eliminate thermal bridges.

Passivhaus consultancy included PHPP energy simulation and performance optimisation, thermal envelope design, advice regarding bio-based materials, passive strategies to combat summer overheating, thermal bridge calculations, and dynamic hygrothermal simulation with WUFI to assess and eliminate the risk of moisture damage.

HVAC design included an air-source heat pump for heating, cooling and DHW production, ducted mechanical ventilation with heat recovery, and an underfloor heating and cooling system with dehumidification. All services were integrated and controlled with Loxone home automation system.

Solgetic has installed the home automation system and programmed the integration of all services on the system. Energy certification and compliance verification with the Spanish Building Regulations CTE HE0 & HE1 was carried out, achieving a class “A” certification.

Els Pallaresos

Description

Solar PV, heating, cooling and home automation system design and installation for a single-family home. The PV system includes a 12-panel array with a 3 kW inverter for self-consumption, with heating, cooling and DHW provided by an air-source heat pump. The Loxone home automation system provides integrated control of all the systems, with fingerprint access control and an innovative system to divert excess solar PV production in the summer months to an electric immersion heater in the DHW tank, providing all-electric solar hot water production.
