Abstract:In the year 2017, about 89% of the total energy consumed in the US was produced using non-renewable energy sources, and about 43% of tenant households were cost burdened. Local governments are in a unique position to facilitate green affordable housing, that could reduce cost burdens, environmental degradation, and environmental injustice. Nonetheless, limited studies have made progress on the costs and benefits of green affordable housing, to guide decision-making, particularly in small communities. This stud… Show more
“…On the instrument level, we urge policymakers to reduce interference between instruments, or otherwise move towards instruments that can address multiple objectives [59,79]. For example, jurisdictions have already been using multi-objective instruments such as density bonus incentives to promote affordable housing [82,83], as well as relaxing zoning laws for densification if a green building label is achieved (i.e. exaction) [84].…”
Section: Integrated Policy Mixes For Retrofitsmentioning
Retrofitting existing buildings is critical for meeting global and institutional net-zero CO₂ emissions goals. Prominent energy and climate policy strategies are aiming to increase notoriously low retrofitting rates by triggering energy efficient and/or decarbonized real estate investments. Although many real estate assets are owned by large-scale investors, the interplay of their retrofit decision-making and policies are under researched. Relying on interviews with four major owner types, industry experts, and policymakers, we unpack the “black box” of retrofit investment and demonstrate how large-scale investors can transform retrofit decision-making processes to meet emissions goals. We show that to accelerate deep retrofits, policymakers should focus on integrated policy mixes, and consider the cross-impacts of policy instruments from various domains on the value-driven retrofitting decision. Instruments indirectly influencing retrofits, such as those targeting affordability or densification, represent a critical avenue for improving the retrofitting policy mix by moving away from single instruments directly targeting energy or emissions aspects. This policy mix should specifically target asset management budgetary decisions, which mainly drive investment planning relevant for deep retrofits.

“…At the same time, the statistics show that SC requires small upfront costs in the construction industry, which will be offset by revenue in the future [29]. For the successful implementation of the SC concept, the resources and market position of organizations are crucial [30].…”
Nowadays, sustainable construction (SC) is considered as a measure to support a healthy economy. The SC concept ensures quality of life and helps minimize the negative impact on the environment, human health, and biodiversity. SC fits into the modern sustainable development (SD) concept due to the ability to improve the environment, energy efficiency, and care for future generations. Despite numerous studies dedicated to the SC concept and implementation, practical matters related to SC including the importance of macroeconomic environmental sustainability are still insufficiently explored. The objective of this research is to study the practical issues of SC in the example of developing countries. Moreover, this work is aimed at determining the importance of the sustainable macroeconomic environment in ensuring SC. With the help of correlation and regression analysis effected for the purposes of the study, the direct connection and strong correlation between the GDP growth in the country and the number of large sustainable infrastructure facilities constructed and put into operation in the Russian Federation and China (correlation coefficient comprised 0.9987) were revealed. Within the current study, the experience of developing countries in SC is also discussed. It has been outlined that for emerging countries, the development of the construction industry environment within the framework of SC is possible in a sustainable business environment. The competitive advantages for SC are considered in social, economic, and environmental systems. Moreover, the models of formation and ensuring competitive advantages of the SC enterprise are presented. This paper reveals that the stability of the macroeconomic environment is a key factor in construction industry growth within the SC for developing countries.
“…Tankless may also last 1.5 to 2 times as long as tank water heaters (20 years) and save 8% to 34% on water (values used in the simulation), depending on water demand; however, demand flow for multiple simultaneous operations must be evaluated and proper capability systems selected [50]. The water demand reduction factor was included in the simulation by a uniform distribution between 0.66 and 0.92 as shown in Equation (8). Acquisition and replacement costs for tankless and tanked water heaters were based on user input for average cost (inflation-adjusted), while the replacement life was estimated at 8-10 years (uniform distribution) for tanked heaters and 15-20 years (also uniformly distributed) for tankless [51].…”
A major consideration for consumers and the residential construction industry is the cost–benefit and break-even of various sustainable construction options. This research provides a publicly available simulation that allows users to compare baseline construction options versus sustainable options and evaluates both break-even costs as well as environmental effects. This R Shiny Monte Carlo simulation uses common pseudo-random number streams for replicability and includes options for solar, rainwater harvesting, wells, Icynene foam, engineered lumber, Energy Star windows and doors, low flow fixtures, aerobic/non-aerobic/city waste treatment, electric versus gasoline vehicles, and many other options. This is the first simulation to quantify multiple sustainable construction options, associated break-even points, and environmental considerations for public use. Using user default parameters, coupled with a 100% solar solution for a baseline 3000 square foot/279 square meter house with 2 occupants results in a break-even of 9 years. Results show that many of the sustainable options are both green for the environment and green for the pocketbook.
