THE GREENEST BUILDING (IS THE ONE THAT YOU DON’T BUILD!) Effective Techniques for Sustainable Adaptive Reuse/Renovation

As an advocate for the older building,I offer the following article as a compendium of useful arguments for the caring institution manager,trustee,or architect.They can be used to support your efforts to convince others to fund the reuse of your wonderful existing buildings from a“green”point of view!Not everyone appreciates the quirks and qualities of older buildings,and,to be fair,they do require more time and attention than brand new facilities.However,there are many advantages to adaptive reuse or renovation.

The Challenges in Providing Affordable Housing in Nigeria and the Adequate Sustainable Approaches for Addressing Them

Despite multiple schemes implemented by various governments around the country, affordable housing remains elusive to the average Nigerian. Because the situation is comparable to that of other developing nations, it remains a key concern in these countries’ socioeconomic development. Over 52% of Nigeria’s population has been claimed to live in shanties, squatter communities, and informal settlements. This article, therefore, reviews the challenges to the provision of affordable housing in Nigeria and the Sustainable approaches to address them. The article’s findings were based on a thorough examination of the literature. The article’s findings indicated that sustainable approaches for addressing Nigeria’s affordable housing barriers may best be examined through the economic, ecological, social, institutional, and technical factors. The paper urges the present regime, investors, lawmakers, and private developers in Nigeria to implement these approaches for affordable housing provision. The findings from this article will add to the current body of knowledge by providing important information on affordable housing provision and re-directing research interest towards affordable housing in Nigeria and other developing countries.

Valorization of semi-solid by-product from distillation of cellulosic ethanol into blends for heating and power

Burning down on semi-solid by-product from distillation of cellulosic ethanol to power upstream steps of its manufacturing is usual.However,this feedstock is homogenous in size and shape,hygroscopic and poorly energetic.These disadvantages make its re-use in the industrial plant very complex.Conversion of this agro-residue into high-performance blends for heating and power is,accordingly,the scientific point of this study.The pilot-scale manufacturing of composite pellets consisted of systematically pressing the residue with sugarcane bagasse at the mass ratios of 1:4,2:4,and 3:4 on an automatic pelletizer machine at 200 MPa and 125℃.The process of compaction lasted for 90 s.Durability and energy density,both increased significantly,from 95.85%to 99.55%and from 27.95 GJ m^(−3) to 32.20 GJ m^(−3) with blending at 3:4.Practically,the semi-solid by-product considerably improved the feeding,thus,enabling the layers of particles to go smoothly through the channel-forming die of the machine.Thereby,blends became stiffer and denser than pellets purely consisting of sugarcane bagasse.Preliminary evidence of the process of pelleting capable of highly valorizing the semi-solid by-product from distillation of cellulosic bioethanol into mechanically stable and energetically effective hybrid fuel grade biosolids exist.The major findings of this paper should be of great relevance to ensure safe and effective transportation and storage of biomass in indoor facili-ties where the risk for the generation of dust and fines and the subsequent off-gassing and self-firing is high.Furthermore,pelletization may optimize the co-generation of heat and steam at the large-scale bioethanol station.
