ABSTRACT
[...]FY22 proved to be a strong year financially, as revenue, operating profit and net assets all improved. [...]consolidated net assets increased $2.8 million as of March 31, 2022. During the year, ASSP: *continued to lead on standards focusing on the top 10 causes of occupational injuries, illnesses and fatalities including confined spaces and lockout/tagout concerns;fall protection and fall arrest;and construction and demolition topics such as the use of drones, heat exposure, excavation and roofing *continued efforts to move training forward with a revised standard addressing hydrogen sulfide and new training techniques *distributed more than 20,000 standards through sales, distributors, special events, and educational offerings and engaged more than 1,300 volunteers representing some 500 organizations, resulting in 17 new or revised industry consensus standards, technical reports and guidance documents The ASSP Foundation helps build a strong pipeline of OSH professionals to make all industries safer and continues to strengthen programs and leverage resources to better serve the safety community.
ABSTRACT
The effect of substrate type and cultivation site in the urban fabric on growth, nutrient content and potentially toxic element (PTE) accumulation in tissues of the halophyte Crithmum maritimum was studied. Plantlets were cultivated for twelve months in containers with a green-roof infrastructure fitted and placed either on an urban second-floor roof or on ground level by the side of a moderate-traffic street. Two substrate types were used;one comprising grape marc compost, perlite and pumice (3:3:4, v/v) and one composed of grape marc compost, perlite, pumice and soil (3:3:2:2, v/v), with 10 cm depth. Plants grew well on both sites, although aboveground growth parameters and nutrient content in leaves were greater at street level. Both cultivation site and substrate type affected heavy-metal accumulation in plant tissues. Cu, Ni and Fe concentrations in leaves and Pb in roots were higher in street-level-grown plants compared to the roof-grown plants, and concentrations of Cu and Mn in leaves and Fe in both leaves and roots were lower in the soilless substrate compared to the soil-substrate, making the soilless type preferable in the interest of both safer produce for human consumption and lower construction weight in the case of green-roof cultivation.
ABSTRACT
Current buildings are responsible for the highest energy consumption, exceeding polluting sectors such as industry and transports. In Portugal, a large part of the building stock was built in the 1970s and 1980s, but buildings dated from the 1960s and 1970s are the ones with the most anomalies and worst quality of construction and, therefore, worst energy performance. The renovation of those buildings can represent an excellent opportunity to correct and improve their energy deficiency and, with that, to promote a more sustainable building stock. The ETICS system is the most used for the renovation of buildings in Portugal due to its lower cost, quick application and thermal efficiency, but it doesn’t solve other problems that may exist, such as structural safety and interior organization of the existing building. The application of prefabricated systems in the envelope has proved to be successful in improving energy efficiency, allowing new volumes and extra areas while contributing to the structural resilience of existing buildings. This paper aims to describe the current situation of the buildings renovation in Portugal and to discuss the potential of innovative envelope retrofitting solutions, using natural materials like timber, and is more concerned with the problems of existing buildings and the need for comfort and space for the occupants.
