Antarctic Base personnel live for 3 months in winter with no natural sunlight. This project compared sleep, by actigraphy, during periods of increased exposure to white light or blue enriched light in 2003. The primary aim was to help define the optimum spectral composition and intensity of artificial environmental light. Nine men and one woman (33 +/- 7 years, mean +/- SD), wore activity and light monitors continuously from 28.2 to 9.10, and kept sleep diaries. Extra light was provided by light boxes (standard white, 5300 K, or prototype blue enriched, 10 000K, Philips Lighting), which were turned on in bedrooms and in communal/work areas approximately 08.00-18.00 hours. After a no-treatment control period, 28.2-20.3, sequential 4-5 week periods of first white, then blue light, were imposed with a further control period 19.9-9.10. A limited baseline study in 2002 (no interventions) similarly measured light and activity in seven men and one woman (30 +/- 7 years). Daily light exposure in winter (lux, mean +/- SD) was doubled in 2003 (maximum 1039 +/- 281, average 64 +/- 21), compared to 2002 (572 +/- 276 and 30 +/- 11), P < 0.05 and P < 0.01, with no differences between white and blue light. There were no major differences in sleep between light conditions in 2003. A delay in sleep timing was found in midwinter compared to control (2003, bedtime, P < 0.05, sleep start, P < 0.05, sleep end, P < 0.01) and sleep fragmentation increased (P < 0.05). Sleep efficiency was slightly higher during all blue light periods compared to all white periods (P < 0.05). The use of higher intensity light of suitable spectral composition is proposed.

At Spark, we’ve partnered with Vibrant Energy Matters to help landlords and their agents plan ahead and take advantage of the opportunity this presents.The legislation means that landlords and agencies won’t be able to let properties with an EPC rating lower than E can’t be let. It’s estimated that 15-20 per cent of properties in the UK will need upgraded to meet the new standards.WHAT’S IN IT FOR ME(ES)?The new regulations offer a great opportunity for property upgrades. The big benefit is that meeting the new regulations can be achieved with little risk to landlords.Vibrant Energy Matters can carry out a property survey to identify what work the property needs and, even better, how and where to get the funding from to carry out the works.Secondly, if landlords aren’t convinced to upgrade to meet the MEES then Vibrant can help landlords to understand the exemptions that exist. For example, landlords do not have to undertake work in the following circumstances:The measures needed to upgrade will not provide payback within seven years;The landlord cannot gain the consent from their tenants despite reasonable efforts;The measures required will reduce the value of the property by five per cent or more.This is a real opportunity for general rental property improvements, through government funding – with the added tenant benefit of cheaper bills in the future!ACT NOW!Before you know it, the MEES regulations will be in effect.Spark’s Partner Managers can arrange a review with Vibrant, who will then provide a comprehensive report on how properties can comply with the new legislation.For more information about Vibrant, visit their website: https://www.vibrantenergymatters.co.uk/Minimum Energy Efficiency Standards MEES spark energy Darren Ypey darren ypey spark vibrant Vibrant Energy Matters September 27, 2017Grant LeonardRelated articles Conveyancing Foundation provides stress management tips1st May 2021 BREAKING: Evictions paperwork must now include ‘breathing space’ scheme details30th April 2021 City dwellers most satisfied with where they live30th April 2021 read more
