This paper provides the first credible evidence on the economic value of “green buildings” derived from impersonal market transactions rather than engineering estimates. We analyze clusters of certified green and nearby buildings, establishing that “rated” buildings command substantially higher rents and selling prices than otherwise identical buildings. Variations in premiums are systematically related to energy-saving characteristics. Increased energy efficiency is associated with increased selling prices -- beyond the premiums paid for a labeled building. Evidence suggests that the intangible effects of the label itself may also play a role in determining the values of green buildings in the marketplace. (JEL G31,M14,Q52,R33)

The impermanence changing of the climates that cause many natural disasters these days has raised the attention of us about the importance of greening towards our planet. The building sector has been verified as the major part of the global solutions. Hence, Green Rating Tools are recommended internationally to guide the developers and public in designing and developing green buildings in order to reduce the negative impact towards human health and environment due to increasing use of natural resources. The research on energy efficiency of Residential New Construction (RNC) was successfully done and analyzed by using the DIALux software and light illumination calculations.

Green building is building that the focus is to maximize the energy efficiency and resources used. While, retrofitting is the process of renovate or refurnish the existing building. Therefore by retrofit existing buildings that comply with green building requirement, it improves the environmental attributes of the buildings. In Malaysia, existing buildings and its communities contribute over 40% of green house gases to the environment. This paper describes a study that explores the potential to retrofit existing campus buildings that response to sustainable green building standard. A validation survey was carried out and the data collected was analysed using SPSS in order to confirm the significance of retrofitting Universiti Teknologi Malaysia (UTM) buildings toward green building initiative. The results show that all the twenty eight identified green elements recorded average index of higher than 3.5 which means that there is significant needs to retrofit the existing buildings to green buildings. This study concludes that it is urgently need for the campus to response to green building requirements in order to achieve higher energy effeciency and this can be done through effective etrofitting of existing buildings.

Low Energy Buildings

In many countries the availability of data about the energy performance of low-energy buildings is quite limited and this lack of information refrains potential investments on green buildings. In 2004, in order to contribute to generate and collect reliable performance data, the European Commission launched the GreenBuilding (GB) Programme aimed at enhancing energy efficiency in both existing and new non-residential buildings on a voluntary basis. Under the umbrella of the GB Programme, the GreenBuildingPlus (GB+) Project operated from 2007 to 2010. One of the activities developed in the project was the creation of a European database on building energy performance. The authors developed a Data Collection Tool, which was used by building owners and their consultants to provide a detailed description of the candidate buildings and their energy efficiency and renewable energy features. In this paper, we present a selection of the results of a statistical analysis of the detailed data of 85 green buildings. The main outputs of the GB+ project are: the total primary energy saved by the 85 buildings amounted to about 115 000 MWh per year and the average percentage of savings is 54%, hence much higher than 25% requested by the GB Programme.

Residential Sector

Existing buildings are the massive percentage of the building stock, and therefore, are the key to improving efficiency; buildings account for an enormous share of the climate change crisis, and approximately 40% of the world total energy consumption (McArthur & Jofeh, 2015). The Egyptian stock of buildings includes about 12 million buildings. 60% of these buildings are residential. The final electricity consumption of the residential buildings in 2010 was 51370 GWh and increased in 2014 to reach 62441 GWh. Thus the share of total energy consumption was 18.8% in 2010 and increased to reach 21.55% in 2014 ("Technology Roadmap - Energy efficient building envelopes.", 2013). Therefore, the residential sector plays an important role in the mitigation of energy consumption crisis, which is expected to increase. The research field and initiatives in Egypt on the green buildings and green buildings retrofits are rare and, if existing, are weakly applied. Unlike in developed countries, there is a large research on building retrofits, e.g., the Residential Property Assessed Clean Energy (R-PACE) program and the weatherization assistance program (WAP) of the department of energy (DOE). Both are examples of the incentives to green building initiatives globally. This paper discusses the challenge of greening the existing residential buildings in Egypt by demonstrating an analysis of the motives and the barriers to applying green measures in the Egyptian market. The research methodology comprises the analytical-comparative method. In the analytical part; the paper identifies the current situation of the residential sector energy consumption in Egypt, and the benefits of greening existing buildings for tenants, investors, and owners. In the comparative part, the current situation of Egypt's Green Market Business Case is compared with the international one, discussing the challenge of greening the residential buildings. The paper summarizes the opportunities to improve the building energy efficiency, incentives, and policies that are developed to address significant financial and technical awareness to building efficiency. These policies will help enable critical market actors to make decisions to promote energy efficiency in existing buildings.

The Continuum

This chapter presents a continuum of building-level actions cities are taking in light of the political and economic constraints they face. It begins by explaining the continuum of building-efficiency standards cities are using as well as a continuum of action that runs from individual buildings to all buildings in a defined district. It examines two categories of standards: those for constructing new buildings and those for retrofitting existing buildings. The chapter also considers the question of who gets to occupy green buildings—with the reduced energy costs they make possible—highlighting how some cities are building green low-income housing using methods that are then taken statewide. Finally, it examines how cities, in collaboration with the private and nonprofit sectors, are serving as test beds for technical, financing, and equity greenovations that can be scaled for policy in larger political geographies and for private market participation.
