Recent research has suggested that energy use for cooling will overtake the demand for heating by 2050, and to avoid increasing costs, facilities managers should turn to high effi ciency cooling and ventilation systems.

reathing Buildings, a UK provider of controlled hybrid ventilation systems, has welcomed the 2018 edition of BB101: Guidelines on ventilation, thermal comfort and indoor air quality in schools. Recently published by the Education and Skills Funding

Agency, the document is aimed at technical professionals involved in the design, specifi cation and construction of new school buildings and the refurbishment of existing buildings. The Building Bulletin sets out the regulatory framework for school ventilation, giving recommended performance levels for compliance with UK regulations while also providing non-statutory guidance on ventilation, thermal comfort and indoor air quality in schools. The BB101 2018 guidance has changed signifi cantly

since the previous BB101 published in 2006. Focusing on the vital balance of indoor air quality, thermal comfort and effi ciency, BB101 2018 sets more stringent air quality targets, is tougher on summertime overheating, and recommends a pre-mixing of air to eliminate cold draughts. Hybrid ventilation systems are also introduced in BB101 2018 alongside traditional natural and mechanical ventilation, off ering specifi ers an alternative ventilation design strategy for schools. “We welcome the updated BB101 since it

comprehensively addresses the issues of air quality, thermal comfort and energy use all of which are key to the design of ventilation systems in schools. This guidance will help ensure that we have effi cient, healthy and comfortable environments in schools so children will benefi t from eff ective teaching and learning spaces,” said Matthew Bray, commercial director at Breathing Buildings.

Showing the government’s new tough stance on air quality in the classroom, the guidelines include maximum CO2 limits which cannot be breached for 20 consecutive minutes. BB101 has also established air fl ow requirements for science labs, halls and gyms to help ensure children experience healthy indoor environments. The new guidance advises that where natural ventilation

is used, or when hybrid ventilation systems are operating in natural mode, in general teaching and learning spaces the daily average concentration of CO2 must be less than 1500ppm when occupied. The maximum concentration should not exceed 2000ppm for more than 20 consecutive minutes each day. Meanwhile, for mechanical ventilation the daily average CO2 level must be less than 1000ppm and must not exceed 1500ppm for more than 20 consecutive minutes each day. Summertime overheating is also re-addressed in the 2018 edition of BB101 with thermal comfort criteria aligning more closely with other building types. Overheating needs to be assessed in terms of operative temperature using the DSY1 2020 weather fi le during the occupied period of 9am - 4pm Monday to Friday from May 1 to September 30, including the summer holiday period. Another change to BB101 has been the additional

guidance on the need to eliminate cold draughts in teaching spaces. This is important since draughts can either raise heating bills by increased use of radiators or aff ect air quality with teachers closing windows to reduce draughts. Therefore, in winter, the guidance advises the mixing of incoming cold air with warm room air to avoid cold draughts in the occupied zone.



harities were the winners of this year’s Polypipe Regatta after the annual event raised £11,000 for good causes.

Almost 50 boats took to the Port Solent to participate in the friendly competition, which celebrated its 20th year on September 5-6 as more than 400 members of

the plumbing, heating and construction sectors raised money for causes including Help for Heroes and the John Merricks Sailing Trust. The two-day event included a day of sailing and a

celebratory evening of food, live music and entertainment. The tightly-fought contest saw independent builders

merchant Elliots take home the grand prize, narrowly beating runner-up, law fi rm Squire Patton Boggs. Heating and plumbing supplier Williams & Co came third. Help for Heroes entered three boats, fi lled with ex-

servicemen and women who are supported by the charity. Polypipe has a long-term association with charity the John Merricks Sailing Trust, which teaches young people how to sail. Trustee Jim Saltonstall announced said the event has helped raise £400,000 for the Trust over the last 15 years. An auction and raffl e raised more than £9,000, with prizes on off er including Manchester United match tickets, and a round of golf and luxury hotel stay at St Andrews.
