Good control strategies are vital to gain the benefits of applying renewable technologies. Truly open protocols and an intelligent approach are the keys to success. Roger Woodward explains why.

Fuel costs for heating were more than halved following the retrofit of CA Group’s transpired solar collector to one of its existing buildings. The independent testing was carried out by BSRIA. and showed an annual saving of 304 MWh.

Rehau, district heating, renewable energy

Gaunts Estate near Wimborne in Dorset is the site of three new district-heating schemes that are powered by three separate anaerobic digestion plants. Throughout the schemes, 1600 m of Rehau’s flexible, pre-insulated Rauvitherm pipework connects the anaerobic-digestion plants to the various farms, dwellings and countryside buildings on the estate.

Rinnai, DHW, renewable energy

Rinnai’s continuous-flow water-heating solutions can work with renewable-energy sources such as solar-thermal and air-source heat pumps. The concept is that the water heater tops up the temperature of stored water heated by renewable energy — but only when required.

CIBSE, Ashford, biomass, boiler, wood pellet, wood chips, renewable energy

The emerging industry for biomass has been hampered by lack of specialist expertise and comprehensive technical guidance. Colin Ashford gives an insight into how a CIBSE application manual will help.

Flakt Woods. heat recovery, energy recovery, heat pump, thermal wheel, AHU, energy efficiency

A reversible heat pump and a thermal wheel are key features of Flakt Woods ventilation system installed as part of the refurbishment of the Arundel Building at Sheffield Hallam University. The system can supply up to 2.5 m3/s of conditioning air into a VAV (variable air volume) system and incorporates inverter-driven compressors. It replaces a natural-ventilation system.

AmbiRad, space heating, control, energy efficiency

AmbiRad’s SmartCom intelligent energy-management controller is compatible with radiant-tube, warm-air and many other types of heating system. It is straightforward and easy to use and has a wide range of energy-optimising features.

Marks & Spencer is to evaluate a central-heating additive that is claimed to be independently proven to reduce gas heating bills by 15%. The decision to try out EndoTherm from Endo Enterprises was made at the Big Innovation Pitch to M&S at the recent Ecobuild exhibition. The company will work with M&S to explore the possibility of applying the additive to the retailer’s estate.

Ideal Commercial Boilers, space heating, boiler, energy efficiency

New Forest District Council is looking forward to substantial reductions in heating costs following the replacement of boilers in 12 buildings that had heating running continuously with the only control being the boiler thermostat. Savings of up to £2500 a site will achieve a payback of just one year at current gas prices.

CP Electronics, lighting control, BMS, BEMS, energy efficiency

Fully addressable and networkable lighting control for Brighton & Hove Albion’s (The Seagulls) new training and teaching facility is provided by systems from CP Electronics. The state-of-the-art American Express Elite Football Performance Centre in Lancing, West Sussex, include CP’s Rapid and Vitesse systems. They were chosen for the flexibility and ease of configuration to any floor layout.

Face to Face Digital, North Building Technologies, BMS, BEMS, energy efficiency

Face to Face Digital, a systems partner of North Building Technologies, has won the 2014 CEDIA award for best energy-management solution. The project is part of a major renovation of a Grade 1 listed country house dating back to 1425 and has reduced energy bills by 75% from the previous figure of £70 000 a year.

Ex-Or, lighting, control, PIR, presence detection, absence detection

With business wanting ever-more control over their operations, Nadine Deery of Ex-Or wonders why so many organisations lack a system to manage their lighting.

Gilberts of Blackpool’s Mistrale 75 ventilation units achieve accurate and stable airflow and also have low air leakage and good thermal performance. Air leakage is as low as 5 m3/h.m2, with a U-value of 0.93 W/m2K, similar to a double-glazed window.

Lindab, chilled beam, space heating, energy efficiency

The Lindab Solus chilled-beam system conserves energy within a building by using high-temperature cooling (HTC) and low-temperature heating (LTH) in one common pair of water pipes working at a common inlet temperature. This means that regardless of whether the zone needs heating or cooling the inlet temperature remains constant, allowing you to harvest the energy saving benefits this brings.
