“…Test t was performed trying to identify the correlation indices between TC, IAQ and IEQ (Table 3). The complete formulation of the regression equation is then: IEQ = 0.011 + 0.27 TC + 0.70 IAQ (6) The unknown variable is the occupants' evaluation of the IEQ. The ANOVA method suggests a greater weight of IAQ.…”

“…IEQ is widely investigated and many findings about how the indoor quality affects human life were defined [4]. However, in the field of low energy buildings, that represent the current target for new and retrofitted buildings [5], few studies focused on IEQ and well-being effects [6], emphasizing the energy aspect [7,8]. In these buildings where the environmental variables are often automatically controlled by dedicated systems and the users' role in this task is low, attention must be paid on IEQ, avoiding possible discomfort [9,10].…”

The quality of the indoor environment, in terms of thermal, lighting, air and acoustic quality, grouped in the Indoor Environmental Quality (IEQ) concept, plays a key role in occupants’ wellbeing and satisfaction. Only in recent years IEQ has been investigated as a whole. Today, IEQ occupies the same place of energy efficiency in the design of buildings, especially those with high performance level as the Zero-Energy Buildings (ZEB). The research deals with an experimental campaign during the cooling season carried out in a ZEB laboratory that involved 100 participants aimed at evaluating the IEQ and the indoor environments (e.g. thermal and air quality). The test consists in a survey, during which each participant is required to answer a questionnaire about how he feels the indoor environment. The experimental campaign was completed with a monitoring activity aimed at detecting the main environmental variables that can affect the participants’ answers. Collected data were treated with regression techniques to highlight possible relationships between them. The results show how in a building with high levels of energy performances the air quality plays a key role on occupants’ evaluation.

South Africa’s private sector - under significant pressure to become energy efficient and employ sustainability principles - has long been implementing energy saving mechanisms. Unfortunately, there seems to exist many misplaced incentives in South Africa's public sector that prevent it from embracing energy-efficient technology. With the falling cost of LED lighting and the rising cost of electricity, however, conversions are increasingly cost efficient. Effecting these changes are increasingly urgent given the national utility-imposed rolling blackouts and climate change concerns. The primary education sector is a particularly attractive test case, since money saved on utilities can be allocated to desperately needed value-adding services in schools. From a technical perspective, however, the cost-benefit of replacements and the range of options facing decision makers could be overwhelming. To assess the impact of replacing fluorescent lights with LED lights at schools in South Africa, we propose a model that draws on smart metering data, a bench-test assessment of available LED lights and tariff rates. The model was validated with field tests at three schools and used to assess the impact at seven local schools. The results show that the setup cost differs substantially from the life-cycle cost, and that buying the cheapest lights could prove to be the costliest decision over the light's life cycle. The results also show that lights contribute from 42% to 57% of electricity expenditure, and that monetary savings of 21% to 39% are achievable by replacing fluorescent tubes with the most efficient LED lighting option available.
