Energy and Indoor Air Quality Impacts of DOAS Retrofits in Small Commercial B...RDH Building Science
Heating, ventilating and air-conditioning (HVAC) typically accounts for 30% to 50% of commercial building energy use. Small commercial buildings often use oversized and inefficient rooftop air handling units (RTUs) to provide both air conditioning and ventilation. A conversion strategy to reduce energy
consumption is the installation of a very high efficiency dedicated outdoor air system (DOAS) to provide ventilation with a separate heat pump system to provide heating and cooling. Decoupling the heating and cooling from ventilation allows for improved energy efficiency and control of space conditions. Upgrades to mechanical systems can also improve the indoor air quality (IAQ) and comfort through control of carbon dioxide (CO2) concentrations, dry bulb temperature, and relative humidity (RH).
A pilot study of eight buildings was conducted to investigate the potential benefits of replacing existing RTUs with high efficiency heat recovery ventilators (HRVs) and air source heat pumps in the Pacific Northwest. This report contains results for a subset of seven buildings for which data is available. The
building energy use before and after the conversion was determined using utility data, energy modeling and monitoring. Indoor environmental conditions were measured at hourly intervals for up to one year postconversion using CO2, temperature, and RH sensors. The data was analyzed to determine changes in energy use and IAQ before and after the conversion.
This paper presents the pilot building results pre- and post-conversion. While several factors need to be in place to ensure optimal performance and cost effectiveness, the pilot shows that replacing RTUs with DOAS systems in existing commercial buildings can both reduce energy use as well as improve indoor environmental conditions. This conversion type is viable for a wide variety of building types and scale-up of the retrofits has the potential to significantly improve a previously underserved segment of the building stock.

Energy Simulation of High-Rise Residential Buildings: Lessons LearnedRDH Building Science
This presentation covers lessons learned from an energy study of over 60 architecturally representative mid to high rise multi-unit residential buildings (MURBS) in BC.
This document discusses ways for large infrastructure projects to achieve carbon neutrality. It proposes that projects should not only account for their direct emissions, but also procure additional low-carbon energy generation to fully offset emissions over the project lifecycle. The document uses HS2 Phase 1 as a case study, estimating how many wind turbines would need to be built to offset construction and operational emissions under different scenarios. Building 165 turbines could ensure HS2 Phase 1 never results in any net increase in atmospheric carbon. The proposal suggests amending legislation to require carbon neutrality over three-year periods to ensure projects do not contribute to climate change.
Optimization of Energy Efficiency and Conservation in Green Building Design U...Totok R Biyanto
The development of green building has been growing in terms of both design and quality. The development of green building bariered by the issue of expensive investment. Actually, green building can reduce energy usage in the building especially in utilization of cooling system. External load plays as major role of reduction in the use of the cooling system. External load is affected by type of wall sheathing, glass and roof. The proper selection of wall, type of glass and roof material are very important to reduce external load. Hence, the optimization of energy efficiency and conservation in green building design is required. Since this optimization consist of integer and non-linear equations, this problem fall into Mixed-Integer-Non-Linear-Programming (MINLP) that required global optimization technique such as stochastic optimization algorithms. In this paper the optimized variables i.e. type of glass and roof were chosen using Duelist, Killer-Whale and Rain-Water Algorithms to obtain the optimum energy and considering the minimal investment. The optimization results exhibited the single glass Planibel-G with the 3.2 mm thickness and glasswool insulation provided maximum ROI of 36.8486%, EUI reduction of 54 kWh/m2·year, CO2 emission reduction of 486.8971 tons/year and reduce investment of 4,078,905,465 IDR.

* All the content is not mine. I have collected the data through different places on the net and books.
A zero-energy building, also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), or net zero building, is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site,or in other definitions by renewable energy sources elsewhere.These buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount.

Carbon Capture in OAPEC Countries and the Circular Economy: A Roadmap to Zero...Dr. Salem Baidas
June 2024. The Organization of Arab Petroleum Exporting Countries (OAPEC) countries are aiming to achieve zero carbon emissions by 2050 by transitioning from a linear to a circular carbon economy. Carbon capture and storage (CCS) technologies are crucial for this transition. This study investigated the Circular Carbon Economy Index (CCEI) scores of six OAPEC member states and found that KSA, Qatar, the UAE, and Kuwait had higher CCEI scores, indicating greater adoption of CCE-transition policies and emission-reducing investments. Based on the findings from this study, specific actions were recommended for OMSs to enhance their CCE transitions and mitigate climate change, including detailed CCS planning, international cooperation, and increased investment in CCS infrastructure.

Competitive Removal of Perchlorate from Contaminated WaterDr. Salem Baidas
March 2023. This study examined the removal of perchlorate anions from water using modified reed (MR), an adsorption material with enhanced anion adsorption properties, in the presence of nitrate and phosphate, which are naturally found in water. Additionally, a multicomponent isotherm model was developed to describe the adsorption of perchlorate. The study found that MR had a higher adsorption capacity for perchlorate than nitrate or phosphate. However, the addition of phosphate or nitrate to a perchlorate solution reduced the MR adsorption capacity. The results of this work provide perchlorate removal efficiency information that is applicable to the design of water treatment systems.

August 2024. Bioenergy is a form of renewable energy that is derived from organic matter, known as biomass. Biomass is used to generate clean electricity, carbon-neutral gas, and sustainable biofuels. Power plants burn biomass to produce clean electricity and heat. Bioenergy sources include wood chips, farming crops, food waste, and manure. There are many benefits to bioenergy utilization, such as revenue from electricity generation and new job creation. In addition, replacing fossil fuels with bioenergy will reduce carbon emissions, mitigating climate change. The use of bioenergy has grown as a result of increasing efforts to reduce the environmental impacts associated with fossil fuel use and to utilize waste for bioenergy production.

Biological Removal of Perchlorate Contamination from Spent AdsorbentDr. Salem Baidas
February 20203. Disposal of untreated perchlorate-laden modified reed (MR) generated in the treatment of contaminated water risks further contamination issues. This study investigated the biodegradation of perchlorate bound to spent quaternary amine-MR adsorbent using enriched microbial culture (EMC). Kinetics experiments were performed to determine biodegradation rates and the total time for complete removal. Results show that EMC can degrade aqueous perchlorate effectively and consistently. EMC can also effectively degrade the adsorbed perchlorate from spent MR. In conclusion, anaerobic biodegradation of perchlorate from spent MR can be used as an efficient, cost-effective, and environmentally friendly treatment method to remove perchlorate from contaminated water.

Plant-based green synthesis of nano particles using environment favorable tec...Open Access Research Paper
In this era of science and innovation, nanotechnology is one of the major and rapidly emerging fields. It works on the creation of nano-particles by interlinking with other innovative science fields and also works on portrayal and utilization of different NPs. The creation of NPs is a critical procedure as it left harmful effects. Scientists are now on the way to foster non-poisonous NPs by green blend techniques. Because of its simplicity of use and organic selection, plant-based NP green mix is presently regarded to be of the best quality among these green, natural techniques. In this article, we address the most recent developments in the green and portrayal plant-derive NPs and their potential employment. Few plant-based NPs that have recently gain a lot of interest due their unique nature and characteristics include, silver NPs, Gold NPs, Zinc NPs and copper NPs. Another important aspect discussed in the paper is potential holding applications of the NPs. Because of the outstanding qualities, Nanoparticles are economically in demand. Due to their numerous applications in the business, hardware, climate, and energy sectors particularly in the healthcare industry. The well-known Ag and Au NPs have been the subject of extensive research in this field and are in high demand for organic applications. Green nanoparticles made from plants are typically less likely to unintentionally have significant effects on people than nanoparticles made artificially. They offer a wide range of possible applications, including, Nano medicine and human health assurance that further covers in different aspects. The paper concludes with a discussion about the future research opportunities in this research venue such as green engineering techniques for generating nanomaterials from plants, microbes, and other everyday resources and its potential challenges associated with plant-based green NP blends, production, depiction and applications.

• Airtightness Backstop-5m3/(hr.m2)
13. Checking NZEB using NEAP
• Current version of SBEM 3.5 to be used - available on SEAI website
• Calculate the performance of the proposed building in SBEM using
the draft Interim Public Sector Specification for fabric and services.
This must be done manually using “table 1” from the draft interim
specification with same size and shape as actual building. This then
becomes the reference building.
• Calculate the performance of the proposed building in SBEM using
the actual design specification for the building
• Compare the primary energy (kWh/m2/yr) and carbon dioxide
emissions (kgCO2/m2/yr) between the building with the actual
performance specification and the building modelled with the draft
Interim Public Sector performance specification.
14. Checking NZEB using NEAP
• Where the actual building performance specification has a primary energy
performance equal to, or lower than the primary energy performance
(kWh/m2/yr) of the same building modelled using the draft Interim Public
Sector Specification it achieves the NZEB performance specification for
energy i.e. The Energy Performance Coefficient (EPC) must be equal to or
less than MPEPC =1.0
• Where the actual building performance has a carbon dioxide emissions
performance equal to, or lower than 1.15 times the carbon dioxide
performance (kgCO2/m2/yr) of the building modelled using the draft Interim
Public Sector Specification it achieves the NZEB performance specification
for carbon dioxide emissions. Ie. The Carbon Performance Coeffient (CPC)
Must be equal to or less than MPCPC =1.15
• EPC/CPC Spreadsheet calculation tool to be released on SEAI website in
coming week
15. • Renewables requirement will be included in TGD L Buildings other than
Dwellings as Renewable Energy Ratio (RER)-20%
• It is recognised that in certain confined situations it may not be possible to
achieve the full 20% RER. In these situations Public Sector Authorities
should provide the optimum proportion of energy from renewable energy
sources that is practically possible.
• In all cases the overall energy performance of the building should be
equivalent to the performance of the building as if the 20% RER had been
achieved.
• Renewable energy sources include Photovoltaics, Heat Pumps (Air source
and ground source), Biomass, Solar Thermal ,Primary Energy Savings
from Combined Heat and Power (CHP), Renewable district heating
• Primary Energy Factor for electricity for calculating RER–the same as
residential 2.19 (3 year forward look)
Interim Public Sector Specification RER
16. Costs
• Performance requirements are based on cost optimal
reports published in accordance with EPBD:
http://www.housing.gov.ie/housing/building-
standards/energy-performance-buildings/energy-
performance-buildings
• Table 5.3a of Non Residential Cost Optimal Report
provides Initial Investment Costs for the energy related
costs for different performance levels for 5 buildings.
• Further analysis currently being performed for RIA.
• Consultant appointed for TGD L 2017 and costs will
be available for TGD L Public Consultation-end Feb.
19. TGD L-Draft Major Renovation
