Dataset Information

Survey dataset on architect?s awareness and adoption of building envelope technologies for energy efficient housing in Lagos State.

ABSTRACT: Low energy houses are forms of housing that use less energy from the design, technologies and building products from any source than a traditional or average contemporary house. The survey dataset examines architect?s awareness and adoption of building envelope technologies (BET) for energy efficient housing in Lagos State, Nigeria. The dataset was based on seventy-four (74) returned questionnaires of both registered and non-registered Architects. A multistage sampling that involved cluster sampling and random sampling of architects in Lagos State was adopted. Descriptive statistical tools were used to present the dataset. The dataset contains the intent of promoting energy sustainability by architect while designing their building envelopes, the awareness of the building envelope strategies to adopt, factors influencing their adoption of these strategies, strategies that can be adopted to improve adoption of building envelope technologies for energy efficiency in housing units. The dataset can be used for evolving housing energy policy by decision makers.

Project description:The mycomembrane layer of the mycobacterial cell envelope is a barrier to environmental, immune, and antibiotic insults. There is considerable evidence of mycomembrane plasticity during infection and in response to host-mimicking stresses. Since mycobacteria are resource and energy limited under these conditions, it is likely that remodeling has distinct requirements from those of the well-characterized biosynthetic program that operates during unrestricted growth. Unexpectedly, we found that mycomembrane remodeling in nutrient-starved, nonreplicating mycobacteria includes synthesis in addition to turnover. Mycomembrane synthesis under these conditions occurs along the cell periphery, in contrast to the polar assembly of actively growing cells, and both liberates and relies on the nonmammalian disaccharide trehalose. In the absence of trehalose recycling, de novo trehalose synthesis fuels mycomembrane remodeling. However, mycobacteria experience ATP depletion, enhanced respiration, and redox stress, hallmarks of futile cycling and the collateral dysfunction elicited by some bactericidal antibiotics. Inefficient energy metabolism compromises the survival of trehalose recycling mutants in macrophages. Our data suggest that trehalose recycling alleviates the energetic burden of mycomembrane remodeling under stress. Cell envelope recycling pathways are emerging targets for sensitizing resource-limited bacterial pathogens to host and antibiotic pressure.IMPORTANCE The glucose-based disaccharide trehalose is a stress protectant and carbon source in many nonmammalian cells. Mycobacteria are relatively unique in that they use trehalose for an additional, extracytoplasmic purpose: to build their outer "myco" membrane. In these organisms, trehalose connects mycomembrane biosynthesis and turnover to central carbon metabolism. Key to this connection is the retrograde transporter LpqY-SugABC. Unexpectedly, we found that nongrowing mycobacteria synthesize mycomembrane under carbon limitation but do not require LpqY-SugABC. In the absence of trehalose recycling, compensatory anabolism allows mycomembrane biosynthesis to continue. However, this workaround comes at a cost, namely, ATP consumption, increased respiration, and oxidative stress. Strikingly, these phenotypes resemble those elicited by futile cycles and some bactericidal antibiotics. We demonstrate that inefficient energy metabolism attenuates trehalose recycling mutant Mycobacterium tuberculosis in macrophages. Energy-expensive macromolecule biosynthesis triggered in the absence of recycling may be a new paradigm for boosting host activity against bacterial pathogens.
