The energy market in Mexico is facing changes due to the incorporation of clean energy certificates (CEL) on the Electric Industry Law (LIE, Ley de la Industria Electrica). One of the aims is to increase the percentage of clean energy use in the national energy matrix. Consequently, the integration of energy efficiency strategies prior to the incorporation of renewables has become essential at different levels. Industrial buildings have significant heat gains and losses through the envelope, mainly due to their vast surface and simple construction systems. This work analyses the typical envelopes of industrial buildings in Mexico and the effect of industrial rooftop photovoltaic (PV) systems over the annual energy consumption. It was found that for temperate climates, the best option would be to insulate the roof. For cities with warm climates, the best approach is to implement a cool roof on a non-insulated layer or to simply insulate the roof. Additionally, the industrial buildings with metallic roofs situated in warmer climates would benefit the most from the implementation of rooftop PV systems. After all, the results point out that the decrease in the required CELs would not influence the savings.

“…It acts to reduce heating needs in the warmer months, but raises cooling needs [86,87]. On the other hand, efficiency improvement methods, such as reflective wall coatings, will decrease summer cooling loads but raise winter heating needs [88]. Most building energy losses occur through the walls and windows [89], and retrofitting can reduce these losses.…”

Given that global energy use today is still dominated by fossil fuels, there is an urgent need to rapidly reduce its use in order to avert serious climate change. However, the alternatives to fossil fuels—renewable and nuclear energy—are more expensive, and have so far done little to displace fossil fuels. Accordingly, reducing energy use must play an important part in both averting climate change and avoiding the depletion of high energy return easily recoverable fossil fuel reserves. This paper examined both the potential and barriers to the adoption of energy reduction measures, with particular attention to domestic energy and passenger transport. The main finding was that energy efficiency approaches alone are unlikely to deliver anywhere near the energy reductions needed in the limited time available. Instead, most energy reductions will have to come from energy conservation, involving less use of energy-using devices, including private vehicles. Achieving such reductions will require changes in lifestyles, especially for residents of OECD nations.

“…Considering the influence of occupants on building energy conservation, occupant behavior would be an important factor to also incorporate in building energy simulations [13]. For example, in a series of simulations, Becherini et al [19] found that load reduction and natural ventilation in historic buildings can improve the effects of thermal coating. The authors modeled and suggested several scenarios through which thermal coating and occupant behavior can contribute to building thermal performance.…”

Occupant Behavior for Energy Conservation in Commercial Buildings: Lessons Learned from Competition at the Oak Ridge National Laboratory

et al. 2019

Accompanying efforts worldwide to deploy sustainable building technologies shows a pressing need for expanded research on occupant behavior. Discourse is lacking concerning drivers of occupant behavior for energy conservation, especially in the case of commercial buildings. This paper explores potential determinants of occupant behavior for energy conservation in commercial buildings. This is investigated in a case study of a two-month energy conservation competition involving eight office buildings at the Oak Ridge National Laboratory. Four buildings achieved energy savings based on the previous year’s baseline. Potential challenges and success factors of occupant behavior for energy conservation during the competition were explored based on an explanatory research design incorporating energy data, participant interviews, and surveys. The findings suggest that both social and technological aspects may be important drivers of energy conservation. The determinants of occupant behavior for energy conservation in commercial buildings suggested for further research include bottom-up involvement, stakeholder relationship management, targeted information, real-time energy visualization, and mobile social platforms. This paper presents initial implications, with a need for further research on these propositions and on their impacts on occupant behavior. This paper aims to contribute to both academia and practitioners in the arena of commercial building sustainability.
