Sustainable Technology for Energy and Environmental Benign Building Design Md. Faruque Hossain1,2 1 Green Globe Technology, 4323 Colden Street 15L, Flushing, New York 11355, USA 2 Department of Civil and Urban Engineering, New York University, 6 Metrotech Center, Brooklyn, New York 11201 Abstract

A sustainable technology has been proposed to satisfy the total energy and gas demand for a building which can be produced by the building itself without any outsource connection. To satisfy the energy demand of 100% of a building some portion of its exterior curtain wall skin can be used as the black body acting PV (photovoltaic) panel to capture solar energy and convert it into electricity energy. The domestic waste including humane feces is proposed to be implemented into transforming process in site where sludge shall be collected into a closed anaerobic detention tank at cellar to introduce into a bioreactor; allowing to produce biogas (CH4) by Methenogenesis, then store, and utilize it for cooking and HAVC equipment. Then, the separated waste water to be collected and treated in site by applying all primary, secondary, and tertiary process and the treated water be used for gardening, and landscaping. Combined all these technologies simply would be an innovative field in sustainable science where a building can itself produce electricity and gas without any outsource connection to meet its total energy and gas demand which is benign to the environment.

Introduction Climate change depends much on buildings as nearly 40% of energy consumption from burning fossil fuel is used by buildings (8,19,30). In 2015, the annual global energy consumption was 5.59 ร— 1020 joules = 559 EJ, in which 2.236x1020 EJ is consumed by residential and commercial buildings (15,22). Because of this level of

energy consumption, buildings have produced nearly 8.01x1011 ton CO2 (218 gtC by building of global total 545 gtC; 1 gtC = 109 ton C = 3.67 gt CO2). The acceleration of using fossil energy by building sector is still increasing worldwide, the condition will not be changed until a sophisticated renewable technology is been developed. Currently, the atmospheric CO2 level is 400 ppm which can be reduced to a comfortable level of 300 ppm CO2 once renewable energy application are being widely used in building sector (40,42). Certainly, a better technology is required for building sector to ensure a cleaner, greener environment by deploying sustainable technology to alleviate energy and environmental perplexity. In this paper, thus, a zero-emission building (ZEB) technology which is a combination of the innovative PV system and the bioenergy production by the building itself has been proposed. In this concept, a building with zero emission building (ZEB) shall greatly be an interesting one to balance of its energy demand if the certain part of the building skin is designed to be a black body assisted PV (photovoltaic) panel to capture solar energy which will reduce nearly 8.01x1011 ton CO2 per year (7,15,16.) In addition to self-producing energy by a building, the domestic waste including human feces and waste water of the building are to be chosen that can be collected into the closed detention tank into the cellar. Then the waste can be separated as (i) waste water, and (ii) humane feces with solid waste into two different chambers. Then the Methenogenesis process would be allowed into the closed detention tank to produce bioenergy in context with domestic solid waste and human feces utilization. It is estimated that a person can produce 0.4-0.5kg/day and 0.5 kg/day that can form the 0.4 m3 biogas/day and this amount of biogas (0.4 m3/day) production which is good enough to cook three meals for a family of four persons in day. Subsequently, the treated waste water in site by applying all primary, secondary, and tertiary process can be used for gardening and landscaping for a building. Application these sustainable technologies would be an interesting field of science to satisfy all its total energy and gas demand which is produced by the building itself which environmentally friendly.

Simulation and Method Model of Photovoltaic (PV) Array A mathematical model of photovoltaic module has been developed to describe the photovoltaic generator for maximum solar energy intaking considering radiation shield, thermocouple, and temperature of the building exterior skin PV panel (Figure 1a). Naturally, the model of the photovoltaic solar irradiance absorbed by the photovoltaic module can be simplified for the maximum power output connected with the temperature module and logarithmic with the solar radiation (12,34,36). The calculation of accuracy and the number of parameters of the current-voltage (I-V) characteristic are necessarily explain the model in single diode equivalent circuit of a PV cell module (3,5,35). Then, using large-scale variation of the irradiance collected by the photovoltaic array at various parameters (voltage proliferation, transformation rate, and PVVI curves) and least control strategy to be used to realize the active and reactive solar volt (Iv+) can be calculated from the model with one diode (Figure 1b).

The next step is to determine the photovoltaic current production by Ipv calculation from the model of one diode (Figure 2a), considering I-V-R relationship (Figure 2b), and using the illumination received by the photovoltaic array to convert from DC to AC and then use for domestic energy and low voltage current demand (Figure 2c).

Design of PV panel To ensure the high efficiency of conversion rate of solar energy, long lasting ability and other essential abilities of the photovoltaic (PV) panel, nanocrystalline materials and films of conductive polymers, using exterior skin of the building wall, are introduced as the materials to build up an advanced photovoltaic (PV) panel (27,28,46). In addition, load resistant factor design (LRFD), which primarily uniformly distributed wind load should also be considered when design such sophisticated photovoltaic (PV) panel to ensure that it is strong enough to protect

itself and operate regularly under storm condition. To guarantee that the tornado resistant PV panel is strong enough, it should have the following wind load resistant capacity of wind velocity (F6 tornado level) 379 mile/hour) at standard air density 1.2 kg/m3 and wind pressure and drag coefficient 1.00 considering per meter square (m2). Since the wind stagnation pressure is half the density of the air times the square of the velocity, the equation for wind pressure can be expressed as ๐‘

Once the sophisticated wind load resistance capacity has been determined, the PV panel need to be analyzed to capture maximum sun light during the whole year based on different directional angles, which can be defined as a spherical coordinate system called Cartesian coordinate system, as shown in Figure 3, whose x represents for horizon conventions, y for east-west, z for zenith. The position of the celestial body in this system is decided by h represents for height and A represents for the azimuth angle while the equatorial system uses the protocol that the z axis points to the North Pole, the y axis identical to the system horizon, and x axis perpendicular to both. Besides, the ฮด decline and ฯ‰ angle hours can also determine the position and analysis generally leads to the insertion of vector control strategies to regulate the active and reactive power based on the combination of different controls, which is reproducible and useable to other complex systems (4,10,11).

The properties of sunlight are considered because of electromagnetic waves and movement of photon flux applied to solar panel since the photo-physical relates to photo-induced the charges (8,31). The first view is fundamental for all applications of solar thermal energy and anti-reflective coatings for solar cells while the second view is also basic with respect to solar cells and solar photochemistry. The combination of the two views is represented by quantum electrodynamics, one of the most fruitful and matured technology in modern physics fields (17, 18). All the hot bodies emit radiation, while black bodies emit the maximum amount of radiation at a given approximately 7000C temperature. However, changes in body color to orange, yellow, white, blue and efficiencies in overlapping loads have been calculated in bandgap and the sun and cells which supposed to be at temperatures of 6000ยฐK and 300ยฐK, respectively (36). The energy density of the solar radiation considering the photon wave frequency has been modeled by using the classical statistical physics in Figure 4a. Then, the maximum solar energy formation considering a single photon excitation at the rate of 1.4 eV with an energy value of 27.77 MW/m2 ยท eV has been modeled in Figure 4b.

(a) The energy density of the solar radiation frequencies shown by the classical statistical physics, (b) The maximum solar energy formation of a single photon at designated wave length (Ultraviolet to Infrared) and frequencies (1017 Hz to 1014 Hz) at the rate of 1.4 eV with an energy value of 27.77 MW/m2 ยท eV. Design of Bioreactor As have mentioned in previous part, building solid waste can be collected into the closed detention tank into the cellar of a building and then be separated into waste water and humane feces including domestic waste into two different chambers. During this process it need to be conducted to treat the waste water by preliminary treatment, primary treatment, secondary treatment, and disinfection. The whole

treatments process can remove nearly 100% pollutants from the wastewater and disinfect the effluent, furthermore, the final product can be utilized for local gardening and landscaping.

Figure 5. Waste water treatment process where effluent is shall be used for gardening and sludge is for further process to produce the biogas.

Besides the treated waste water in situ, the product sludge shall undergo in situ anaerobic tank to produce bioenergy. It is a transformation process by performing filters electrochemically active carbon nanotubes (CNT), which can adsorb and oxidize chemicals in the anode effectively (23,41). It is a novel system of waste treatment to combine both adsorption and oxidation at the anode CNT and further oxidation in situ generated hydrogen peroxide (H2O2) in the cathode CNT in a small-scale. The factors affecting the efficiency of the treatment, and the oxidation mechanism of the system is studied systematically. The model of this calculation demonstrated that H2O2 flow may be affected by the electrode material, the cathode potential, pH, flow rate, and oxygen dissolved (37,39,50). The maximum flow H2O2 of 1.38 mol L-1 m-2 C are to be achieved CNT L-1 m-2 with an applied cathodic potential V -0.4 (vs. Ag / AgCl), a pH of 6.46, a rate flow 1.5 ml min-1 and a DO influent flow of 1.95 mol L-1 m-2. Furthermore, phenol can be used as aromatic compound model for assessing the removal efficiency of the system and its oxidation

rate correlated directly with H2O2 flow. H2O2 shall probably react with a phenol species anodically activated to itself, which is the reason why H2O2 radical form cannot remove phenol efficiently. In addition, the formation of electrochemical polymer through chain reactions phenolic radicals can also contribute to 13% of phenol removal. A stable removal efficiency of 87.0 ยฑ phenol 1.8% to 4 h of continuous operation can be achieved with an average rate of oxidation of 0.059 ยฑ 0.001 mol h-1 m-2 (28,39). The electrochemical CNT filtering system thus developed with H2O2 generated in situ for a new application of filters in this process, where carbon nanotubes can be used as an effective treatment for removing organic pollutants nearly 100%.

After this step, the product can be stored in a closed chamber to allow the thermophilic anaerobic co-digestion process to thicken. Then, the sludge is to be placed in free oxygen tanks called digesters and heated to at least 95OF for 10 to 15

days to stabilize the thickened sludge by converting much of the material into methane gas (2,7). It will therefore make it safer environment for the bioreactor when waste being discharged, which will stimulate the growth of anaerobic bacteria of Desulfovivrio, Methanecoccus, that consumes organic matter in the sludge and thrive in a free anaerobic environment, which is different with bacteria in the aeration tanks.

Figure 7. The methanogenesis process shows the detail biochemical process of M. maripaludis and D. vulgaris bacterial syntrophic interaction, highlighting the central energy-generating and consuming the mechanism to produce methane as a source of bioenergy.

Results and Discussion Conversion of Solar Energy To establish a connection between the number of light-quanta by steady state๏ผŒthe intensity of solar irradiance is considered as the primary source of energy volts to convert it into electricity energy by PV panel (13,31). The number of stationary states of light-quanta is a certain type of polarization whose frequency is in the range of ฮฝr to ฮฝr + dฮฝr. From there maximum solar radiation it can be achieved at 1.4 eV with an energy value of 27. 77 mW/m2 ยท eV based on an average of 5 hours solar irradiance

harvesting in a day peak levels, which is the equivalent of 27,770 kWh / year or 7.6 kWh / day energy (3,45). Due to physical principles, there are losses in the conversion of solar energy into DC power and converting direct current into alternating current (AC). This ratio of AC to DC is called "derating factor ', which is typically 0.8 (23,36). Thus, the surface texture of selective solar metal is excellent in energy conversion (33, 34), since the current net conversion by solar panels is 125% higher level with an efficiency of 80% (8,13,14) of solar panels which means that (27,770 x 1.25 x 0.8) = 27,770kWh/year or 7.6 kWh/day. Energy remains equal to the solar initially what was before the introduction to the solar panel. Necessarily, the maximum solar irradiance is depicted 1.4 eV with an energy value of 27.77 mW / m2 ยท eV in Figure 8 per year in an average of five hours a day maximum levels for 365 days referents by panel Solar and black body (6,9,33). A standard residential house requires average 12 kWh/day (2,12,36). Since the produced energy is equivalent to 27,770 kWh / year or 7.6 kWh / day, which in fact will meet the energy demand for a residential house required 12 kW/day by using only two solar panel of 1 m2 each. The average energy consumption rate monthly of commercial office or buildings is about 10,000 kWh/day for a foot printing 32m x 31m with 30 meters (10 floors), respectively (18,21,29). In calculation of a building is an average of 32m x 31m footprint with a height of 30m, total installed 1m2 PV panels requires 1,195 units (945 + 250) with the capacity of 7.6kWh/unit energy production can provide total energy x 1,195 = 9,082kWh/day to meet the daily energy demand of about10,000 kWh/day for a commercial office or building.

Figure 8. The figure depicted the blackbody radiation in various temperature at 5770 K power is 6.31 ร— 107 (W/m2); Peak E is 1.410 (eV); Peak ฮป is 0.88 (ฮผm); Peak ยต is

2.81x107 (W/m2ยทeV).

Cost Comparison The total cost for 30 years energy consumption from a conventional source for a standard building (100 people capacity) at 0.12/kwh of 4000kwh per month is (30 x 12x 4000 x 0.12) = $172,800.

Conversion of Biogas Since the anaerobic Co-digestions of domestic perishable waste and human feces is conducted into the bioreactor, thus, the methanogenesis started into the bioreactor

immediately. Consequently, the inorganic loading rate started to form COD from the various parameters of Raw thermophilic, Raw Mesophilic, Ground Thermophilic, Row Mesophilic, Sludge Thermophilic, and Sludge Mesophilic condition of the waste (Figure 9).

Figure 9. Shows the inorganic (COD) loading rate formation in (a) Raw thermophilic, and Raw Mesophilic, (b) Ground Thermophilic, and Raw Mesophilic, (c) Sludge Thermophilic, and Sludge Mesophilic condition of the waste. The effects of inorganic loading rate are enforced to form anaerobic digestion foaming to produce Bio Energy (CH4), and Fig. 10 shows the results of the formation

Conclusion The development of residential and commercial buildings in cities, suburban and rural areas around the world are accelerating exponentially over the last few decades. Consequently, climate change is increasing rapidly due to conventional energy consumption by the building sector. In addition, traditional domestic waste and wastewater management are creating severe environmental pollution, causing damage to human health and harmful to flora and fauna in the aquatic environment. Here, the โ€œGreen Scienceโ€, an innovative technology could be the cutting-edge science to solve the energy, and gas demand for a building. Just because this technology โ€œGreen Scienceโ€ could produce these two vital needs by itself by using the exterior building skin as the PV panel to produce energy and domestic waste as the source to produce gas that would in fact be the most innovative technology for building a sustainable world.
